Chapter 1. Introduction
Thank you for purchasing Microchip Technology’s CAN/LIN/J2602 PICtail™ (Plus)
Daughter Board. This board is compatible with both the Explorer 16 Development
Board and the PIC18 Explorer Board to facilitate rapid implementation and evaluation
of applications that use Controller Area Network (CAN) and Local Interconnect Network
(LIN) interfaces and are implemented on dsPIC33F Digital Signal Controllers, PIC24
16-bit microcontrollers and PIC18 8-bit microcontrollers.
This chapter introduces the CAN/LIN/J2602 PICtail™ (Plus) Daughter Board and
provides an overview of its features. Topics covered include:
• Overview
• Functional Overview
1.1
OVERVIEW
The CAN/LIN/J2602 PICtail™ (Plus) Daughter Board augments development of
dsPIC33F and PIC24 based applications on the Explorer 16 Development Board and
augments development of PIC18 based applications on the PIC18 Explorer Development Board. It offers two interfaces: one for a CAN bus and one for a LIN bus. Although
CAN and LIN protocols are used most extensively in automotive applications, the
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board can be used in any application that
requires interfacing to a CAN and LIN bus.
Both interfaces can be used simultaneously. Appropriate bus transceivers on the
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board complete the physical layer requirements of the CAN and LIN bus protocols. In both cases, communication is driven by
the dsPIC33F, PIC24 or PIC18 device on its respective development board.
Figure 1-1 shows the CAN/LIN/J2602 PICtail™ (Plus) Daughter Board plugged into the
PICtail Plus slot on the Explorer 16 Development Board, and Figure 1-2 shows the
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board plugged into the PICtail slot on the
PIC18 Explorer Development Board. The CAN/LIN/J2602 PICtail™ (Plus) Daughter
Board draws 9V, 5V and 3.3V DC power from the connected development board. The
external power supply and MPLAB ICD 3 are plugged into the development board.

LIN Operation
The CAN/LIN/J2602 PICtail™ (Plus) Daughter Board connects two LIN transceivers
with integrated voltage regulators to UART modules on a dsPIC33F, PIC24 or PIC18
control device on the Explorer 16 or PIC18 Explorer Board. The LIN transceiver monitors the LIN bus, conditions the incoming signal and passes it to the UART module on
the control device. The LIN transceiver responds to a “Transmit Enable” from the control device by conditioning an output signal and placing it on the LIN bus.
A Power-down mode turns the transmitter and voltage regulator off, leaving only the
receiver and wake-up circuits in operation. Each LIN circuit includes a Master/Slave
jumper to accommodate a Master node on the LIN bus.
In order to use the transmit enable for the LIN2 transceiver with the PIC18 Explorer
Board and a PIC18 device, the LIN2TXE pin must be connected to 5V, or a pin on the
PIC18 device, to control it. This can be done by connecting a jumper wire on the J18
header between LIN2TXE and either the 5V supply also on the J18 header, or an available pin on either the J17 or J18 header. For more information on the J17 and J18
headers see Section 2.3 “Auxiliary Header Pinouts”.
2011 Microchip Technology Inc.
DS70319B-page 13
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board User’s Guide
For PIC18 devices, the pinout for the LIN1 and LIN2 modules can be different. The
jumpers J4, J8, J13 and J14 are for choosing between these pinouts. For the specific
pinout that is necessary for the PIC18 that is used, refer to that device’s data sheet. For
PIC24 and dsPIC33 devices, make sure to leave the J4, J8, J13 and J14 jumpers
disconnected. Otherwise, these connections can disrupt LIN communications.
For detailed information on the MCP2021-500 LIN Transceiver, refer to Microchip Data
Sheet MCP202X “LIN Transceiver with Voltage Regulator” (DS22018).
1.2.2
CAN Operation
The CAN/LIN/J2602 PICtail™ (Plus) Daughter Board connects two high-speed CAN
transceivers to ECAN modules on the control device on the development board. The
CAN transceivers convert the differential signal on the CAN bus to a digital signal for
the ECAN module. It also converts the ECAN output digital signal to a differential signal
for the CAN bus.
All PIC18 devices have one CAN module, which is connected to the CAN1 transceiver
(U3). For some PIC18s, there is an optional alternate pinout for the CAN module that
is chosen by an internal MUX. This alternate pinout is connected to the CAN2 transceiver (U4). Depending on the number of pins the device has, this alternate pinout has
two options. These two options are chosen by the two jumpers (J15 and J16). For
detailed information on the CAN pinout options for the PIC18, refer to that device’s data
sheet. Also, the alternate CAN pinout for some PIC18s is the same as the LIN1 pinout.
If this is the case, LIN1 and CAN communications cannot be used simultaneously. For
PIC24 and dsPIC33 devices, make sure to leave J15 and J16 disconnected.
Otherwise, these connections can disrupt CAN communications.
In Sleep mode, the CAN transmitter is turned off, and the receiver operates at a lower
current level. The control device monitors CAN activity and switches the transceiver
back to normal operation when needed.
For detailed information on the MCP2551 High-Speed CAN Transceiver, refer to
Microchip Data Sheet MCP2551 “High-Speed CAN Transceiver” (DS21667).

2.2.1
Explorer 16 Board PICtail™ Connector (J7)
Explorer 16 Board PICtail connector J7 (see Reference 1), a 120-pin signal connector
that carries signals from the I/O pins of the dsPIC33F or PIC24 device on the Explorer
16 Board to the CAN/LIN/J2602 PICtail (Plus) Daughter Board. This connector handles
the following signals:
• 9V, 5V and 3.3V DC input to the CAN/LIN/J2602 PICtail (Plus) Daughter Board
• Signals from the ECAN modules on the dsPIC33F or PIC24 device to the CAN
transceivers on the CAN/LIN/J2602 PICtail (Plus) Daughter Board
• Signals from the UART modules on the dsPIC33F or PIC24 device to the LIN
transceivers on the CAN/LIN/J2602 PICtail (Plus) Daughter Board
• LIN Bus Fault Communication
2.2.2
Auxiliary Headers (J17, J18)
Auxiliary Headers J17 and J18 (see Reference 2) make a various set of signals available from the development board. These headers can be used for monitoring, testing
and development purposes. Refer to Section 2.3 “Auxiliary Header Pinouts” as well
as the board schematic for more details on these headers.
2.2.3
LIN Bus Master/Slave Select Jumpers (JP12, JP13)
The LIN1 and LIN2 Bus Master/Slave Select Jumpers (see Reference 3 or
Reference 7) are used to indicate the presence of a master device on the LIN bus.
Placing jumper JP13 or JP12 pulls the LIN bus high via a 1K pull-up resistor. This can
be detected by nodes on the LIN bus as an indication that a Master node is present.
There can be only one Master node on a LIN bus.
2.2.4
LIN Transceivers (U1, U2)
A set of MCP2021 LIN transceivers (see Reference 8 and Reference 4) provide the
interface between the UART modules on the dsPIC33F, PIC24 or PIC18 device and the
LIN bus. The transceiver converts the signals from the UART modules on the control
device to a 5V regulated signal for the LIN bus. The power supply to the LIN transceivers is selectable between +12V or +9V with jumper J2 (see Reference 6). While the
+9V is available from the development board, the +12V supply must be connected
externally to J1 (see Reference 10). For PIC18 devices, the LIN 1 and LIN 2 modules
can be used on two sets of pins chosen by the J4, J8, J13 and J14 jumpers. Choose
the correct pinout corresponding to which PIC18 device is used.
2.2.5
LIN Bus Connectors (J10, J12)
The LIN1 and LIN2 bus connectors are 3-pin terminal blocks that connect the
CAN/LIN/J2602 PICtail (Plus) Daughter Board to a LIN bus. LIN1 connector J10 (see
Reference 9) connects UART1 module on the dsPIC33F, PIC24 or PIC18 control
device to the LIN bus via the LIN1 transceiver. LIN2 connector J12 (see Reference 5)
connects UART 2 module on the dsPIC33F, PIC24 or PIC18 control device to the LIN
bus via the LIN2 transceiver.
2.2.6
LIN Transceiver Power Supply Select Jumper (J2)
This 3-pin jumper (see Reference 6) selects the power supply to LIN transceivers U1
and U2. Either +9V DC is supplied from the development board or +12V DC is supplied
from an external power supply connected to J1 (see Reference 10).
2.2.7
External +12V DC LIN Power Supply Terminal Block (J9)
External +12V DC power for the LIN transceivers must be connected to J1 (see
Reference 10).

A pair of MCP2551 CAN transceivers (see Reference 11 and Reference 14) provide
the interface between the ECAN modules on the dsPIC33F, PIC24 or PIC18 control
device and the CAN bus. The transceiver converts the signals from the ECAN modules
on the dsPIC33F, PIC24 or PIC18 device to a pair of differential CAN bus signals.
2.2.9
CAN Bus Termination Jumpers (JP4, JP5)
Termination Jumpers (JP4, JP5) are provided to terminate the CAN bus. Jumper JP4
(see Reference 12) places a 120 ohm termination resistor across the CAN bus connected to CAN1. Jumper JP5 (see Reference 16) places a 120 ohm termination
resistor across the CAN bus connected to CAN2.
2.2.10
CAN Bus Connectors (P1, P2)
Nine-pin D-type connectors connect the CAN/LIN/J2602 PICtail (Plus) Daughter Board
to a CAN bus. CAN1 connector P1 (see Reference 13) connects ECAN 1 module on
the dsPIC33F, PIC24 or PIC18 control device to the CAN bus via the CAN transceiver.
CAN2 connector P2 (see Reference 15) connects ECAN 2 module on the dsPIC33F or
PIC24 device and the ECAN1 module’s alternate pinout on the PIC18 device to the CAN
bus via the CAN transceiver.
For PIC18 devices, the alternate pinout of the ECAN1 module can be used on two sets
of pins chosen by the J15 and J16 jumpers. Choose the correct pinout corresponding
to the PIC18 device used. The CAN bus provides high and low differential signals.
2.2.11
Alternate LIN1 and LIN2 Module Pinout Jumpers (J4, J8, J13, J14)
For PIC18 devices, depending on which device is used and how many pins it has, the
LIN1 and LIN2 module will be available on two different sets of pins. The J4, J8, J13
and J14 jumpers are used to select between these two options (see Reference 17).
2.2.12
Alternate CAN1 Module Alternate Pinout Jumpers (J15, J16)
For PIC18 devices, depending on which device is used and how many pins it has, the
CAN 1 module’s alternate pinout chosen by its internal multiplex will be available on
two different sets of pins. The J15 and J16 jumpers are used to select between these
two options (see Reference 18).
2.2.13
PIC18 Explorer Board PICtail™ Connector (J3, J5, J6, J9, J11)
PIC18 Explorer Board PICtail connector (see Reference 19) is made up of five connectors that carry signals from the I/O pins of the PIC18 device on the PIC18 Explorer
Board to the CAN/LIN/J2602 PICtail (Plus) Daughter Board. This connector handles
the following signals:
• 9V, 5V and 3.3V DC input to the CAN/LIN/J2602 PICtail (Plus) Daughter Board
• Signals from the ECAN module on the PIC18 device to the CAN transceivers on
the CAN/LIN/J2602 PICtail (Plus) Daughter Board
• Signals from the UART modules on the PIC18 device to the LIN transceivers on
the CAN/LIN/J2602 PICtail (Plus) Daughter Board
• LIN Bus Fault Communication

CAN/LIN/J2602 PICtail™ (Plus)
DAUGHTER BOARD USER’S GUIDE
Chapter 3. CAN/LIN/J2602 PICtail (Plus) Daughter Board
Tutorial Program
This chapter provides a brief description of the code that can be used with the
CAN/LIN/J2602 PICtail (Plus) Daughter Board. When connected to the PIC18 Explorer
Board, the code included with the board can be used. When the daughter board is connected to the Explorer 16 Board, some examples available on Microchip’s web site
(www.microchip.com) can be used. Topics covered include:
• PIC18 Tutorial Overview
• dsPIC33F and PIC24H Tutorial Overview
3.1
PIC18 TUTORIAL OVERVIEW
The PIC18 tutorial in this chapter demonstrates the CAN module features of the
PIC18FXXK80 family in mode 1. When either the PIC18F46K80 PIM or PIC18F66K80
PIM is connected to the PIC18 Explorer Board, and is interfaced with the
CAN/LIN/J2602 PICtail (Plus) Daughter Board, the tutorial demonstrates how to transmit and receive with the CAN module.
The PIC18 tutorial project, ECAN_Daughterboard.mcp, is written in C for MPLAB
C18. Make sure that the correct PIC18FXXK80 device is chosen for the project. This
tutorial program transmits data over the CAN bus when the RB0 push button is
pressed, and has three filters with three buffers to receive data sent over the CAN bus.
The project contains three files, main.c, CAN.c, and CAN.h. The CAN.c and CAN.h
files contain the functions used for CAN communication. These files can be easily
ported to other projects if needed. The main.c file contains the code that handles the
CAN communication for this specific tutorial.
Specifically for this example, while running in mode 1, when a CAN message is
received that fits one of the three filters, 0x111, 0x444, and 0x0A0, the LEDs on PORTD
increment by one. When the push button on RB0 is pressed, a CAN message is transmitted. To show that the device is working properly, the LED on RD7 is toggled continuously at a constant rate.
To effectively demonstrate this tutorial, a device is needed to transmit and receive messages to and from the PIC18FXXK80. Any device capable of CAN communication can
be used, but a CAN bus analyzer is the simplest to use. Microchip has a CAN bus analyzer available for purchase on the web called the CAN bus Analyzer Tool
(APGDT002). This analyzer tool can query the CAN bus for all messages transmitted
and received. It can be connected to the DB9 connectors on the CAN/LIN/J2602 PICtail
(Plus) Daughter Board.
