TUTORIAL OVERVIEW
Creating projects with the Microchip Graphics Library requires that a number of files be
included in the project. It is much more efficient to start a new project based on an existing demo application release with the Microchip Graphics Library. The tutorial in this
chapter uses that route to guide development of new applications. All demo
applications are written in C for MPLAB C30.
Note:
This tutorial was developed using MPLAB IDE v8.40 and MPLAB C30
Compiler v3.30 as the software tools, and the Microchip Graphics Applications Library v2.10. Before proceeding, verify that you have at least these
revision levels.
The Demonstration Applications are provided with the Microchip Applications Library
downloadable from http://www.microchip.com/mal. When installed in a specified path
(for example,C:\Microchip Solutions\), the help file Graphics Library
Help.chm is located in the path C:\Microchip Solutions\Microchip\Help\Graphics Library Help.chm. The help file contains the Graphics
Library release notes and description of the API. It also contains useful information on
the demo applications that can run on the development board.

Set Up the Device Configuration
The device configuration for the PIC24F devices can be set by two methods:
• Using configuration macros in the source code
• Using the Configuration Bits window in MPLAB IDE
To display the Configuration Bits window, select Configure > Configuration Bits from the
menu bar (Figure 3-6).
All demos that come with the Microchip Application Libraries include the configuration
macros in the code. It is recommended to use these configuration settings in the code.
To do this:
1. Open the Configuration Bits window.
2. Select the check box Configuration Bits set in code, located at the top of the
window, to enable the use of the configuration in code.
For building applications that do not include configuration macros, it is possible to set
the device configuration by using the Configuration Bits window. To do this:
1. Open the Configuration Bits window.
2. Set the Configuration bits by clicking on each line item and selecting an option
from the drop-down menu that appears. The Configuration bits for the PIC24F
device on the PIC24FJ256DA210 Development Board should be set as shown
in Figure 3-6.

“Configuration Bits set in code” checkbox at the top of the Configuration bits
window. Refer to the “MPLAB IDE Simulator, Editor User’s Guide”
(DS51025) for additional information.
Connect and Enable MPLAB REAL ICE In-Circuit Emulator
1. Connect the MPLAB REAL ICE in-circuit emulator module to the PC with the
USB cable.
2. Connect the MPLAB REAL ICE in-circuit emulator to the PIC24FJ256DA210
Development Board with the short RJ-11 cable.
3. Apply power to the development board.
4. From the Debugger menu, choose Select Tool > REAL ICE to set MPLAB REAL
ICE in-circuit emulator as the debug tool in MPLAB IDE.
Once selected, MPLAB IDE will connect to the MPLAB REAL ICE in-circuit emulator
and report that it has detected the module (Figure 3-7). Then it connects to the MPLAB
REAL ICE in-circuit emulator verifying the firmware loaded on the module is appropriate for the selected device (PIC24FJ256DA210). If not, it will load the necessary firmware. Once the firmware is verified to be correct it connects to the development board
and determines if the target device (i.e., the PIC24FJ256DA210) is present or not.

DEBUGGING THE CODE
Assuming that you have modified the code to implement your own application on the
PIC24FJ256DA210, it is possible that it will not work after your first build and needs to
be debugged. MPLAB IDE provides an editor and several debug features, such as
breakpoints and Watch windows, to aid in application code debugging.
This section includes:
• Editing Application Code
• Using Breakpoints and Mouseovers
• Using Watch Windows
3.7.1
Editing Application Code
To view application code so it may be edited, do one of the following:
• Select File > New to create new code, or File > Open to search for and open an
existing code file.
• Double click on a file in the Project window to open an existing code file. An example is shown in Figure 3-10.
For more information on using the editor to create and edit code, see the Help files for
the MPLAB IDE Editor.

Using Breakpoints and Mouseovers
To set a breakpoint in code, use one of the following methods:
• Double Click in Gutter: Double click on the window gutter next to the line of code
where you want the breakpoint. Double click again to remove the breakpoint.
• Pop-up Menu: Place the cursor over the line of the code where you want the
breakpoint. Then, right click to pop up a menu and select “Set Breakpoint”. Once a
breakpoint is set, “Set Breakpoint” will become “Remove Breakpoint” and “Disable
Breakpoint”. Other options on the pop-up menu under Breakpoints are for
deleting, enabling or disabling all breakpoints.
• Breakpoint Dialog: Open the Breakpoint dialog (Debugger > Breakpoints) to set,
delete, enable or disable breakpoints. See MPLAB IDE Help for more information
on this dialog.
A breakpoint set in code appears as red “stop sign” with a “B”. Once code is halted,
hovering over the variables pops up the current value of those variables (Figure 3-11).
The mouseover feature must be set up. From the menu bar, select Edit > Properties;
from the Properties dialog, select the Tooltips tab, and then click the Enable Variable
Mouseover Values check box.

USER’S GUIDE
Chapter 4. Development Board Hardware
4.1
INTRODUCTION
This chapter provides a more detailed description of the hardware on the
PIC24FJ256DA210 Development Board, and the procedures on configuring its many
features. Topics covered include:
• Functional Overview
• General Hardware Features
• Setup and Configuration
4.2
FUNCTIONAL OVERVIEW
The development board is centered on the PIC24FJ256DA210 microcontroller which
integrates in a single package a graphic controller, a CTMU for touch-sensing applications, and a wide range of other peripherals.
The microcontroller’s Graphics module is capable of driving TFT, CSTN and MSTN displays in a number of sizes and color depths. Many display applications (up to 8 bpp in
QVGA) can be run from the microcontroller’s 96 KByte RAM buffer. For bigger displays
or higher color resolution, the microcontroller can directly interface with external RAM
devices for additional data storage. For non-volatile data storage, both serial and
parallel Flash memory devices are provided.
The built-in USB functionality can be configured to operate in Device mode, as a
stand-alone USB host, or as a USB On-The-Go (OTG) device. Host and OTG modes
can be additionally configured for different types of bus sensing and external regulator
support.
Push buttons, CTMU touch sensors and a potentiometer are provided for a variety of
user-defined inputs. These share three common I/Os on the microcontroller, along with
three LEDs, and are configured manually with jumpers.
A PICtail Plus edge connector is provided, allowing the development board to be used
with different compatible PICtail Plus daughter board. An RS-232 port is provided for
general purpose serial communications between the development board and a host
PC; this serial port can also be re-configured to be available through the PICtail Plus
connector.
Figure 4-1 shows the main components of the development board.

GENERAL HARDWARE FEATURES
4.3.1
PCB Layout
The PIC24FJ256DA210 Development Board uses several design strategies to provide
a stable demonstration and development environment. Users should note these
features and design tips when developing their own graphic applications.
The development board uses a four-layer PCB design; this allows high-frequency
signals to be routed in a way to avoid crosstalk between data signals. It also gives
additional noise protection due to improved grounding.
For additional noise protection, oscillator circuits and crystals are laid out with appropriate grounding and guard rings. The layout guidelines are described in Section 2.
“Guidelines for Getting Started with 16-Bit Microcontrollers” of the device data
sheet.
Each group of color signals (Red, Green and Blue) is routed together to reduce intercolor crosstalk. This means, for example, that Red signals are close together and do
not mix with Green and/or Blue signals. Ideally, it is recommended to run a ground wire
or trace between groups of color signals to reduce crosstalk. Also, the traces for color
data should be as close to equal length as possible, and avoid the use of vias wherever
possible.
4.3.2
Microcontroller
The development board is supplied with the PIC24FJ256DA210 microcontroller
directly soldered to the board at U2. The device is installed with the notched corner (pin
1) oriented to the lower right. Vias are provided around the device, which allow access
to all microcontroller signals; this is labelled on the board as U9. A riser may be installed
here to facilitate connections to user added components in the prototyping area.
DS51911A-page 32
2010 Microchip Technology Inc.
Development Board Hardware
4.3.3
Oscillator Options
The PIC24FJ256DA210 Development Board is equipped with two separate oscillator
circuits. The main oscillator uses an 8 MHz crystal (Y1) and functions as the controller’s
primary oscillator.
A second oscillator is implemented using a discrete oscillator circuit with a 32.768 kHz
(watch type) crystal (Y2). This is connected to the microcontroller’s SCLKI pin, providing an external clock source for the secondary oscillator option used to clock the RTCC
and Timer1 modules. A discrete oscillator is used in this application to free up an additional pin for general I/O use. To use this clock source, the microcontroller must be configured to use External Clock mode for the secondary oscillator. For additional
information on secondary oscillator configuration, refer to the “PIC24FJ256DA210
Family Data Sheet” (DS39969).
4.3.4
Power Supply
The PIC24FJ256DA210 Development Board supports two power options.
In the first, an unregulated DC supply of 9V to 15V is supplied to J1. (A power supply
is not provided with the development board, unless the kit was purchased. If one is
required, Microchip Part number AC162039 is recommended). The 5V and 3.3V
regulators (Q1 and Q2, respectively) provide stable power to the board, as well as
compatible display daughter boards. Regulated 3.3V voltage is derived from the 5V
regulated voltage.
Optionally, an external, regulated DC power supply can be used to provide power to
the board. Two separate voltages are required: +5V (to TP3, the red terminal near the
upper left corner, adjacent to J9) and +3.3V (to TP4, the yellow terminal near the upper
right corner, adjacent to the prototype area).
The on-board voltage regulators can deliver a total combined current of 800 mA. If a
larger display with a current rating higher than 800 mA (combined board and display
rating) is to be used, the display board must be independently powered. In these cases,
power to the display cannot be provided through display connector V1. Only common
ground between the development board and the larger display should be connected
through V1.
A green power-on LED (D6) indicates when power is applied to the board from either
source. The power-on LED indicates the presence of +3.3V.
4.3.5
Programming and Debugging Interface
The PIC24FJ256DA210 Development Board can be programmed using either the
(PICkit) connector (J9) or the 5-wire, RJ-11 (ICD) connector (J10). Only one interface
may be used at any given time.
Use J9 to connect a PICkit 3 programmer, or other similar programmer/debugger
devices, to program the development board. Use J10 to program the board using the
MPLAB ICD 3 debugger or MPLAB REAL ICE in-circuit emulator.
4.3.6
Reset Switch (S4)
Switch S4 is connected to the MCLR line of the microcontroller. When pressed, it pulls
the MCLR pin low, resetting the microcontroller (and any application the microcontroller
is running). The same reset signal is also connected to the Reset signals of the PICkit
and ICD connectors. However, any applications being run on PICtail daughter cards
installed in the PICtail Plus port will not be automatically reset. In these cases, the user
must provide an alternate hardware signal to the daughter board.

PIC24FJ256DA210 Development Board User’s Guide
4.4
SETUP AND CONFIGURATION
The PIC24FJ256DA210 Development Board has been designed with a wide range of
hardware options. These allow the user to evaluate the entire range of the microcontroller’s features, include user-defined inputs, explore the range of graphics options,
and incorporate USB connectivity options.
To maintain flexibility, many of the board’s hardware options are configured using standard jumpers. In a few cases, modifying the board at several locations (by the addition
or removal of resistors) may also be required. Details of the configuration options and
how to select them are provided in the following sections. A list of the development
board’s configuration jumpers is provided in Table 4-1; their corresponding locations
are shown in Figure 4-2.

The only display mode available in this configuration is 16 bpp.
CTMU channels and push buttons are available with certain PICtail™ Daughter
Boards only. The number of inputs available depends on the daughter board and
the application. See Section 4.4.6 “PICtail™ Plus Card Modular Expansion
Connector” for additional information.
LED outputs are shared with CTMU input channels.
User-Defined Inputs and LEDs
The PIC24FJ256DA210 Development Board implements a variety of user-defined
inputs: push button switches, capacitance-sensing touch pads, a potentiometer, and
four LEDs. The development board multiplexes the switches, touch sensors, potentiometer and three of the LEDs through three I/O pins (RB5, RE9 and RG8). For each of
these pins, only one input mode can be chosen at any given time. The fourth LED (D4)
shares a pin with an address line for the external memory devices.
Note that the implementation of shared inputs and outputs used in the development
board is not a recommended design practice. In this case, it is implemented in consideration of I/O pin constraints. Using separate pins for different input and output features
is always recommended.
If the CTMU touch sensors are enabled, the LEDs can be used simultaneously. However, care must be taken in the application to switch the I/O pins alternately as analog
input and digital output as required. Please refer to the “PIC24FJ256DA210 Family
Data Sheet” (DS39969) for details on configuring the I/O ports.
The user-defined features are configured using jumpers J13, J14 and J15. In some
cases, modifications to accompanying resistors are also required. The locations of the
components are shown in Figure 4-3. A summary of the jumper settings is provided in
Table 4-3.

USB Connectivity
The PIC24FJ256DA210 Development Board supports three distinct full-speed USB
modes: Host mode (default), Device mode, and USB On-The-Go (OTG) mode.
Although the particular operating mode of the microcontroller is determined by the
application and device configuration, the development board hardware also needs to
be configured to suit the mode as well. These are selected by the USB mode jumpers
(Figure 4-4, callout 1). Additional current sense options for Host and OTG modes are
configured with setting I/O jumpers and modifying certain on-board resistors (callouts
2 and 3).
Note:
Only one USB mode may be enabled in hardware at any time.

USB HOST MODE (DEFAULT)
To enable the USB Host Mode:
1. Install jumper JP6.
2. Remove jumpers JP5 and JP7.
3. If the application requires detection of drawn current by the device on the USB
line, enable the detection of an analog OVERCURRENT signal at pin AN19/RG8
of the microcontroller as follows (Figure 4-4, callout 2):
a) Open jumper JP13 (disconnects CTMU_PAD1, LED D1 and Switch S1).
b) Populate R26 with a 0 resistor.
c) If installed, remove resistor R27. (R27 may have been installed if the USB
OTG mode was previously enabled. See Section 4.4.3.1 “UART and USB
OTG Mode (TX Remapping)” for more information.)
In Host mode, use J4 (Type A Female USB connector) to connect to an external USB
device.

To enable USB Device mode:
1. Install jumper JP7.
2. Remove jumpers JP5 and JP6.

USB ON-THE-GO (OTG) MODE
To enable the USB OTG mode:
1. Install jumper J5.
2. Remove jumpers J6 and J7.
3. To detect the status of the regulated output voltage of the charge pump, connect
the charge pump PGOOD signal to the microcontroller (Figure 4-4, callout 3):
a) Remove jumper JP14 (disconnects CTMU_PAD2, LED D2 and switch S2).
b) Populate resistor R32 with a 0resistor (connects PGOOD signal to pin
AN21/RE9).
4. To have software control of the charge pump, connect the SHDN signal to the
microcontroller (Figure 4-4, callout 3):
a) Remove jumper JP15 (disconnects the potentiometer, switch S3,
CTMU_PAD3 and LED D3).
b) Populate resistor R45 with a 0 resistor.
In USB OTG mode, use J7 (Type Micro AB Female USB connector) to connect with
external USB OTG devices.
Note:
4.4.3
Enabling USB OTG mode may require the remapping of the UART’s TX
signal. See Section 4.4.3.1 “UART and USB OTG Mode (TX Remapping)” for more information.
UART (RS-232)
The development board provides one UART, with its RX and TX signals appearing on
pins RD0 and RF3 of the PIC24FJ256DA210, respectively. The signals can be
configured to appear at one of two places:
• The RS-232 external serial port (default).
• The PICtail Plus connector, as signals U1RX (pin 2) and U1TX (pin 4).
An RS-232 level shifter (U3) has been provided with all necessary hardware to support
the external serial port. The DB-9F serial connector (P1) is wired to support hardware
flow control; however, the flow control signals are not connected to the microcontroller.
The port is configured as a Data Communication Equipment (DCE) device.
Note:
The TX and RX signals are mapped to the microcontroller pins using the
Peripheral Pin Select (PPS) feature. When developing applications, make
sure that the pins are remapped properly to use the UART Receive and
UART Transmit signals. Refer to Section 10.4 “Peripheral Pin Select” of
the PIC24FJ256DA210 data sheet for a detailed discussion of PPS.
The UART’s availability is configured by jumpers JP16 and JP17. Their location is
shown in Figure 4-5.
To access the UART through the RS-232 serial port:
1. Set jumper J16 to position 1-2 (USART_TX – TX) (default).
2. Set jumper J17 to position 1-2 (USART_RX – RX) (default).
In this configuration, a host PC running the appropriate application can communicate
with the development board using the serial channel. Use a standard
(“straight-through”) serial cable connected to P1.
To access the UART through the PICtail Plus expansion port:
1. Set jumper J16 to position 2-3 (U1TX – TX).
2. Set jumper J17 to position 2-3 (U1RX – RX).
In this configuration, the U1RX and U1TX signals appear at pins 2 and 4 of the PICtail
Plus connector, respectively.

UART CONFIGURATION
M
4.4.3.1
UART AND USB OTG MODE (TX REMAPPING)
Normally, the UART TX signal appears on pin RF3, along with the USBID signal. When
USB OTG mode is enabled, USBID takes priority over the TX signal. If the UART is also
needed, this requires the TX signal to be remapped to another pin. The development
board allows for RG8, normally used for S1/PAD1/LED1, to function as the TX signal
in these cases. In addition to remapping the pin in software using PPS, resistor R4, R5,
R26 and R27 will also need to be changed (Figure 4-6).
To remap the TX signal with USB OTG enabled:
1. If populated, remove resistor R4 (callout 1). Alternatively, remove jumper JP13
(callout 2). (Both disconnect the TX signal from pin RF3.)
2. Populate resistor R5 (callout 1) with a 0 resistor (connects USBID signal to pin
RF3).
3. Populate resistor R27 with a 0 resistor (callout 2) (connects TX signal to pin RG8).
4. If populated, remove resistor R26 (callout 2) (disconnects Overcurrent Sense
signal).

UART AND DISPLAY BACKLIGHT (RX SIGNAL)
The UART’s RX signal is mapped to only one pin (RD0) of the microcontroller. This pin
is also used by the development board to optionally control the backlight for the display
daughter board; all functions are multiplexed through the same jumper, JP12. If either
of the backlight control options is selected, the UART becomes unavailable to the external RS-232 port.
4.4.4
Graphics Port
The PIC24FJ256DA210 Development Board can support TFT, MSTN and CSTN
displays. Displays of 4, 8 and 16-bit data widths are supported. The 64-pin display Connector V1 (J3) (on the right hand side bottom corner of the board) is provided for connection of Microchip display boards.
4.4.4.1
TFT AND STN INTERFACES
When developing applications using TFT displays and the Graphics Display Prototype
Board, the 16-bit display bus can be used to send 16-bit RGB data (5-6-5 bits respectively) to a standard 24-bit (8-8-8) or 18-bit (6-6-6) RGB display. To do this, color data
from the microcontroller is mapped to the Most Significant bits (MSbs) of the display.
The Least Significant bit lines of the display (3-2-3 for 24-bit displays, 1-0-1 for 18-bit)
are then tied to the MSb. This technique allows full brightness whenever the MSb is ‘1’,
and full blackness when the MSb is ‘0’. The controller-to-display data mapping is
detailed in Table 4-5.

input is described in Table 4-6. Configuration of the different data widths is done by the
graphics controller module through the register interface. Refer to the

4.4.4.3
RESISTIVE TOUCH SCREEN INTERFACE
The development board supports display panels with a built-in 4-wire resistive touch
screen. The resistive touch screen interface (X-, Y-, X+ and Y+) is used to directly connect to the touch screen signals. X+ and Y+ are both analog and digital signals, and
are connected to I/O ports that can function both as analog inputs and digital outputs.
X- and Y- are digital output signals only, and are connected to digital I/O ports. The X+
and Y- signals are multiplexed with the SPI based touch screen controller.
When using the 4-wire resistive touch screen interface, jumpers JP9 and JP10 must be
set to their default positions, bridging pins 1 and 2 (Figure 4-7, callout 1).
4.4.4.4
SPI TOUCH CONTROLLER INTERFACE
Two SPI channels (two Chip Select lines) are provided in Display Connector V1 to
support display panels equipped with the following:
• SPI-Based Timing Controller: Some displays requires programming of an
on-board Timing Controller (TCON) to initialize the settings of the display before it
is used. The TCON is used to synchronize the display glass timing with the display controller signal timing. This option is provided on the pins A27 (SPI_SCK),
A28 (SPI_MISO), B27 (DISP_SPI_CS) and B28 (SPI_MOSI) of display connector
V1.
• SPI-Based Touch Controller: In some cases, an SPI-based touch module is used
with the display. Every time a touch is detected, it sends an interrupt to the host
controller to inform the host that there is a fresh touch input and the information
must be forwarded from the touch module to the host controller through SPI communications. The development board shares two of the pins of the 4-wire resistive
touch screen with the interrupt and chip select line of the SPI based touch controller. The sharing is done this way since in any system, only one of the two types of
user interface will be used.
The SPI-based touch control features are configured by jumpers JP9 and JP10
(Figure 4-7, callout 1). To enable the use of an SPI-based touch controller, set jumpers
JP9 and JP10 to bridge positions 2-3.
Note:
As of this writing, none of the Microchip display boards support SPI-based
touch controllers.

4.4.4.5
BACKLIGHT CONTROL
Depending on the display glass being used, backlight control is provided as an
ON/OFF signal, or as a PWM pulse train for a continuous range of brightness. Jumper
JP12 (Figure 4-7, callout 2) selects which signal is enabled on display connector V1.
By default, backlight control is disconnected (position 2-4).
• To enable BKLT_EN (ON/OFF), set JP12 to bridge 2-3.
• To enable BKLT_PWM (PWM controlled contrast), set JP12 to bridge 1-2.
Note:
4.4.5
If either of the backlight control modes is selected, access to the UART will be
disabled. See Section 4.4.3.2 “UART and Display Backlight (RX Signal)”
for more information.
On-Board External Memory
The PIC24FJ256DA210 can be used to create a graphics solution without any external
memory resources. However, in cases where the application requires a higher color
depth (8 bits per pixel or more), or larger storage for images and data, external SRAM
and Flash memory devices are provided on the development board.
Both SRAM and parallel Flash memory can be enabled at the same time. The
Enhanced Parallel Master Port module (EPMP) accesses memory on both devices with
the same data and address lines. PMCS1 is used as the Chip Select signal for the
SRAM, and PMCS2 is used for the parallel Flash. Note, however, that configuring a
memory addressing size option for one device selects the same size for the other.
If all 19 address lines of the EPMP are not required, PMA17 and PMA18 can be configured for other purposes. PMA17 can be used to control LED D4, while PMA18 can
be reconfigured to function as an I/O on the PICtail Plus Expansion port.
For more information on using the EPMP, refer to “Enhanced Parallel Master Port
(EPMP)” (DS39730) for more information.
4.4.5.1
EXTERNAL SRAM
The PIC24FJ256DA210 Development Board is provided with 512 Kbyte of external
SRAM, populating U6. By default, only 256 out of the 512 KByte is enabled; this allows
PMA17 to control LED D4 in the default board default configuration. If required, the
SRAM may be upgraded to 1 MByte by replacing U6 with a different device. The SRAM
interfaces with the microcontroller through the EPMP interface. Use of external SRAM
is optional if internal 24/96 Kbyte RAM of PIC24FJ256DA210 cannot accommodate the
required frame buffer size for a specific color depth and resolution combination.
SRAM access time is an important aspect of the interface to the EPMP port. In most
QVGA based applications, the use of a 55 ns access time is enough to meet the refresh
requirements of the display. The use of a 10 ns access time SRAM on the board is due
to the fact that VGA resolution display, which requires more bandwidth, can also be
driven by the development board.
The SRAM can be configured for one of three memory address ranges, shown in
Table 4-7.

EXTERNAL FLASH MEMORY
The PIC24FJ256DA210 Development Board has two external Flash memory devices.
Selection is controlled by jumper JP23. Only one can be enabled at any given time:
• 512 Kbyte Parallel Flash (SST39LF400A), connected to the EPMP port.
• 16 Mbits (2 Mbyte) SPI Serial Flash (SST25VF016B).
Flash memory configuration uses the same jumpers and resistors as SRAM configuration (Figure 4-9). An additional jumper, JP23 (callout 1), selects between the serial and
parallel devices.

To enable the support of multiple PICtail Plus Daughter Boards, the development board
maps selected I/Os to multiple PICtail Plus pins. In some cases, using certain daughter
boards may mean disabling some functionality on the development board. In general,
when the PICtail Plus connector is in use, these development board features are not
available:
1. All CTMU channels (most daughter boards).
2. EPMP Address lines PMA18 and PMA17. This reduces the accessible area of
the parallel Flash device to 256 Kbytes, regardless of the device installed
3. PMP Byte Enable line PMBE1. This limits parallel Flash and SRAM devices to
Word accesses; in turn, this limits display modes to 16 bpp mode.

DAUGHTER BOARD-SPECIFIC HARDWARE MODIFICATIONS
Depending on the PICtail Plus Daughter Board to be used, hardware modification to
the development board may be required. The modifications re-route different signals
from the microcontroller, particularly EPMP signals, to different pins of the connector.
All changes consist of placing 0 resistors in designated areas to enable the connections, or removing existing resistors in other places to disable existing connections. All
of the resistors are located in a single group adjacent to the Flash memory area, shown
in Figure 4-10. They are also shown as a single group in Figure A-6 of the development
board schematic.

For additional information on the configuration resistors, as well as specific modifications for particular daughter boards, please refer to Appendix B. “Modifications for
PICtail Plus Daughter Boards”.
4.4.7
Current Measurement
To provide additional information on developing hardware solutions, the development
board includes current measurement points at three locations. These permit the current
drawn by the different branches of the development board to be measured separately.
The measurement points are unpopulated jumpers at JP1, JP2 and JP3 (Figure 4-11,
callouts 1,2 and 3, respectively). To measure current, cut the trace on the reverse side
of the board that shorts the two vias for the jumper, then insert the current measuring
device between the two vias.
JP3 can be used to measure the total current drawn by the board from the 9V power
supply. JP1 can be used to measure the total current (at 3.3V) drawn by the microcontroller, and JP2 can be used to measure the total current drawn by the remaining 3.3V
branch of the board. The current drawn by the 5V branch can be measured by subtracting the sum of the currents of JP1 and JP2 from the total current measured at JP3.

Other Considerations
The PIC24FJ256DA210 supports two slightly different configuration options for its
Enhanced PMP. The configurations are selected by the ALTPMP Configuration bit; this
allows some flexibility in hardware design by remapping several address and Chip
Select lines to different pins. Table 4-9 summarizes the differences.
The development board is designed with the assumption that the Enhanced PMP interface is in the alternate configuration (ALTPMP = 0). This allows the use of three additional analog pins that would otherwise be used by the EPMP module. Users should
keep this in mind when designing applications that will be used with the development
board.

Appendix B. Modifications for PICtail Plus Daughter Boards
B.1
INTRODUCTION
This appendix provides a detailed description of the modifying the development board
for use with different PICtail Plus daughter boards. Topics include:
• Overview of the PICtail Plus Interface
• Modifications for Specific Daughter Boards
B.2
OVERVIEW OF THE PICTAIL PLUS INTERFACE
To maximize their versatility, many of Microchip’s development and demonstration
boards are equipped with the PICtail Plus interface. This allows boards with a standardized edge connector to directly access the I/O lines of each other’s microcontrollers and
expand their functionality. In most cases, this is used to allow a more fully-featured
board (such as the PIC24FJ256DA210 Development Board) to connect to a PICtail
Plus daughter card and add new features to a pretape application (for example, adding
100 Mbps Ethernet using the Fast 100 Mbps Ethernet Daughter Board).
The basis for the design of the PICtail Plus interface is Microchip’s adherence to a standard migration pathway throughout its microcontroller families: that is, for a given
microcontroller package pin count, certain I/O ports are always located on specific pins
of the PICtail Plus interface, and specific peripherals are almost always associated with
specific I/O ports. This permits daughter boards to use a specific pin for SPI communication, for example, because microcontrollers will always have an SPI peripheral associated with that I/O pin, and that PICtail Plus connector pin.
There are exceptions, however. Because of its complex graphics interface and
enhanced PMP, the PIC24FJ256DA210 microcontroller does not map I/O ports and
peripherals in the same way as other 100-pin devices are mapped. To maximize compatibility, this requires a change of the PICtail Plus mapping for the PIC24FJ256DA210
Development Board. The complete mapping from microcontroller to interface are
shown in Table B-1.
Since PICtail Plus-compatible daughter boards are designed to the standard interface,
some additional remapping of the interface is needed to make the PIC24FJ256DA210
Development Board compatible. Provisions to do this are made by connecting a group
of I/O lines the resistor bank described in Section 4.4.6 “PICtail™ Plus Card Modular
Expansion Connector”. Populating or removing specific resistors in this bank allows
the remapping of certain signals and restoring compatibility with specific daughter
boards. As of this writing, the development board can be made compatible with all
available PICtail Plus daughter boards.
A list of specific signals controlled by the resistor bank is provided in Table B-2; note
that some signals are routed to multiple pins on the PICtail Plus interface by default to
maximize compatibility. Table B-3 shows the same information to specifically highlight
which signals can be remapped to a particular pin.
Section B.3 “Modifications for Specific Daughter Boards” describes the specific
resistor changes required for each PICtail Plus daughter board.
