Power Supplies
www.ti.com
When power is supplied to J3, JP1 selects power to the TSC2014 VDD/REF, either from the
TSC2014EVM-PDK motherboard (that is, the USB-MODEVM Interface Board) or from an external power
supply (through the J4 connector). See the schematic and PCB silkscreen for details.
The TSC2014EVM-PDK motherboard (the USB-MODEVM interface board) supplies power to J3 of the
TSC2014EVM. Power for the motherboard is supplied either through its USB connection or on terminal
blocks on the board.
4.1
TSC Power
Power for the TSC2014 VDD/REF can be supplied either from the motherboard or from an external power
source, selected by setting JP1. When the shunt is installed on JP1 pins 1-2, power for VDD/REF comes
from J3.8 (+VD1). +VD1 is a power source from the motherboard (the USB-MODEVM) and can be
selected in the range of +1.2 VDC to +3.3 VDC. When the shunt is installed on JP1, pins 2-3, power for
VDD/REF comes from an external power supply through the J4 terminal block.
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
TSC2014 data sheet (SBAS522) before applying power to the EVM. Also, note
the power polarity to J4.
4.2
Stand-Alone Operation
When used as a stand-alone EVM, the power can be applied through the J4 terminal block. Note that a
shunt must be installed on JP1, pins 2-3 for stand-alone operation
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
TSC2014 data sheet (SBAS522) before applying power to the EVM. Also, note
the power polarity to J4.
4.3
USB-MODEVM Interface Power
The USB-MODEVM Interface Board can be powered from several different sources:
• Through a USB connection
• 6-VDC to 10-VDC ac/dc external wall supply (not included)
• Laboratory power supply
When powered from the USB connection, JMP6 should have a shunt from pins 1-2 (the factory default
configuration). When powered from 6 VDC to 10 VDC, either through the J8 terminal block or J9 barrel
jack, JMP6 should have a shunt installed on pins 2-3. If power is applied in any of these ways, onboard
regulators generate the required supply voltages, and no further power supplies are necessary.
If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM interface
board, JMP6 should have no shunt installed. Voltages are then applied to J2 (+5 VA), J3 (+5 VD), J4
(+1.8 VD), and J5 (+3.3 VD). The +1.8 VD and +3.3 VD also can be generated on the board, from the
+5-VD supply, by the onboard regulators; to enable this supply, the switches on SW1 must be set to
enable the regulators. Move the switches to the ON position (higher position, looking at the board with text
reading right-side up) to enable the regulators. If +1.8 VD and +3.3 VD are supplied externally, disable the
onboard regulators by placing the SW1 switches in the OFF position.
Each power-supply voltage has an LED (D1, D2–D8) that lights when the power supplies are active.

Reference Voltage
No additional reference is needed for the TSC2014EVM because the reference voltage used for the
TSC2014 device is provided from the VDD/REF pin of the TSC2014. A reference is needed only for
single-ended input mode when measuring the AUX or temperature. TSC2014 touch screen measurements
are operated under differential (ratiometric conversion) mode and, therefore do not need any reference.

EVM Operation
This section provides information on the analog input, digital control, and general operating conditions of
the TSC2014EVM, both by itself and as part of the TSC2014EVM-PDK.
5.1
Analog Input
The analog input sources (touch screen and auxiliary input) can be applied directly to J1 (top or bottom
side; refer to Table 1), or through signal-conditioning modules available for the modular EVM system.
5.2
Digital Control
The digital control signals can be applied directly to J2 (top or bottom side; refer to Table 2). The modular
TSC2014EVM also can be connected directly to a DSP or microcontroller interface board, such as the
HPA449, or to the USB-MODEVM Interface Board if purchased as part of the TSC2014EVM-PDK. For a
current list of compatible interface and/or accessory boards for the EVM or the TSC2014, see the
TSC2014 product folder on the TI web site (www.ti.com).

USB-MODEVM Interface Board
The simple diagram shown in Figure 1 shows only the basic features of the USB-MODEVM Interface
Board. The board is designed for a TAS1020B USB controller with an 8052-based core. It features two
positions for modular EVMs, or one double-wide serial modular EVM can be installed.
For use with the TSC2014, the TSC2014EVM is installed in the topmost EVM slot, which connects the
TSC2014 digital control interface to the I2C port of the TAS1020B. Because the TSC2014 has no audio
features, the lower EVM slot (which is connected to the TAS1020B digital audio interface) is not used.
As configured at the factory, the board is ready to use with the TSC2014EVM. However, if external I2C
control is desired, the signals may be applied to J6 on the USB-MODEVM board. To view all the functions
and configuration options available on this board, see the USB-MODEVM Interface Board schematic
appended to this document.

GUI Software and Operating Descriptions
7.1
Program Description
Afteryou complete the TSC2014EVM-PDK software installation (described in Section 6.2), evaluation and
development with the TSC2014 can begin.
When the TSC2014EVM-PDK software starts on your PC, the interface GUI is displayed as shown in
Figure 3. On the top-left side of the GUI, a lit green LED indicates the digital serial interface type; this
indicator should be I2C for the TSC2014EVM-PDK. The next box to the right shows the location and
version of the firmware.
The two LEDs near the top center of the GUI can be used to perform a software reset of the TSC2014
and stop the TSC2014 analog-to-digital converter (ADC) operation. Note that the two LEDs reflect the
corresponding bits inside the CB1 (see the TSC2014 data sheet).
When the SW Reset LED is lit (blue), bit 1 of CB1 is set to logic '1' and the TSC2014 is in the software
reset mode. When the LED is off (black), bit 1 is set to logic '0'; the TSC2014 is not reset and is in normal
operating mode.
When the Stop ADC LED is lit (red), bit 0 of CB1 is set to logic '1' and the TSC2014 ADC stops. When this
LED is off (black), bit 0 goes to logic '0' and the TSC2014 operates normally.
Next to the SW Reset and Stop ADC LEDS, two boxes labeled CB0 and CB1 display the current/default
settings of the TSC2014 control byte mode 0 (CB0) and mode 1 (CB1), respectively. See the TSC2014
data sheet on the control byte and its two modes.
The data in CB0 are written to the TSC2014 while writing to a control register; CB0 is the command byte.
Data in CB1 are written to the TSC2014 when one of the following events occurs:
• Bit 0 (STS or Stop ADC) is set by clicking on the Stop ADC LED.
• Bit 1 (SWREST or SW Reset) is set by clicking on the SW Reset LED.
• Bit 2 (RM or Resolution) is set at the Human Interface tab.
• Bits 3 through 6 (Converter Function Select) can be set at the Configuration tab beneath the CFR1
section.
Most product and design evaluations can be implemented using the three primary tabs on the
TSC2014EVM GUI: Human Interface, Configuration, and Command Line Interface. Clicking on a tab
accesses the functions that correspond to the specific tab. This section provides a detailed discussion of
the functions of these tabs.

7.2
Human Interface Tab
Refer to Figure 3 for a view of the Human Interface tab; this screen is the default (startup) tab of the GUI,
and shows both touch data (such as X-, Y-, and Z-coordinates of each touch on the screen) and
non-touch data (for example, AUX and temperature).
7.2.1
Touch Screen Control Function
The touch screen box in this tab updates when a touch is detected on the touch screen. As the touch
screen is drawn on, the motion on the touch screen is translated into pixels in this box. The software takes
X, Y, Z1, and Z2 readings which are shown to the right of the touch screen box. As the touch pressure
increases, the pixel size increases; a lighter touch results in thinner pixel sizes.
(NOTE: The Z-value displayed is not exactly what is described in the TSC2014 data sheet because the
data sheet equations are calculated as if there is a known resistance of the touch screen being used.) The
value used in the evaluation software is calculated by Equation 1 of the TSC2014 data sheet, but without
multiplying the value by the Rx-plate resistance. This raw value is shown as Z beneath the measured
touch data, X, Y, Z1, and Z2; it normally ranges from 0 to 4, with larger numbers representing a more
forceful press on the screen. Using the Maximum Z Value to Display knob, you can set a threshold so that
the program does not display lightly pressed points. This threshold setting helps to eliminate the display of
spurious points that may result from touch screen mechanical bouncing or physical jitter.
The display in the touch screen box can be cleared by pressing the Clear Graph button on the screen.
7.2.2
Data Acquisition Functions
The TSC2014 provides for measuring an auxiliary input voltage (AUX) and the temperature. A data
acquisition function on this tab displays the measured values for these parameters. Measurements are
updated only when the touch screen is not being pressed, and the Auto Reading LED is on.
Temperature is displayed using both measurement modes described in the TSC2014 data sheet. Using
the TEMP1 and TEMP2 measurements, a temperature reading with 2°C resolution and accuracy is
achieved. Using only the TEMP1 measurement, a reading with 0.3°C resolution is possible, but requires
that the user know the TEMP1 value at +25°C. This setting normally requests a calibration that the user
performs. The evaluation software program presumes that TEMP1 = 590 mV at +25°C.
By default, the software continuously reads non-touch data, AUX, TEMP1, and TEMP2, and automatically
updates these values in the Non-Touch Data Acquisition section of the GUI display. To stop data
acquisition, click on the green LED Auto Reading in the top-right corner.
Both AUX and temperature measurements require a reference voltage, which is provided to the TSC2014
VDD/REF pin. The VREF value (in volts) controller box can be written with the corresponding VREF voltage.
7.2.3
Direct Configuration
The TSC2014 parameters (or modes) can be set up or configured in two ways. One approach is to set up
the control registers (this procedure is described in the Configuration Tab section). The second method is
to write directly to the TSC2014 through control bytes. Most of the device configuration information and
status of the TSC2014 can be accessed through writing to or reading from the TSC2014 control registers.
Additionally, several parameters or modes can be accessed through the direct configuration, including
Resolution, ADC Power-Down, ADC Stop, and SW Reset. See the TSC2014 data sheet for more details.
In the Human Interface tab, two direct configuration modes can be accessed: one is Resolution mode; the
second is ADC Power-Down mode.
The TSC2014 ADC can be configured to operate in either 10-bit or 12-bit resolution mode. This option can
be directly configured using Control Byte Mode #1 (or CB1), or by writing to bit #13 of Control Register
CFR0. Clicking on the resolution option in this tab changes the resolution setting in CB1. Note that the
CB1 box at the top of the GUI updates when any of the control bits change. You may also need to change
the resolution setting in CFR0 (which is discussed in the Configuration Tab section) to make them
consistent.

The tab has four sections, corresponding to the configuration registers CRF0, CFR1, CFR2, and the four
thresholds registers, respectively. The two status boxes, one under the CFR1 section and the other under
the Threshold Selection section, display the current values written to these TSC2014 control/configuration
registers.
Note that a digital box is next to each of these multiple selectors; clicking on this box sends the data to the
corresponding control registers.

7.3.1
ADC Configuration (CFR0)
This section controls the parameters in TSC2014 configuration register CFR0. Each button or selection
controls a single parameter.
• Pen Control Mode:
The button controls whether the touch data acquisition is started or initialized by a host processor
command (manually) or by a touch on the screen (automatically). The default option is to start
acquisition by touching the screen.
• Stop ADC
This button can stop the TSC2014 ADC, or put the ADC into normal operating mode; the default is
normal operating mode. It has the same function as the Stop ADC LED (bit #1 of CB1) at the top
center of TSC2014EVM GUI.
• Resolution
This button selects between 10- and 12-bit resolution. Note that bit #2 of CB1 also controls the
resolution; thus, you may need to double-check the settings in both places to make sure they are
consistent. The default setting is 12-bit resolution.
• Conversion Clock
The internal clock that runs the ADC can run at 4 MHz, 2 MHz, or 1 MHz. Note that at 4 MHz, only
10-bit resolution is possible; 12-bit resolution is not. Therefore, you should verify the resolution setting
after selecting a 4-MHz conversion clock. By default, the clock runs at 2 MHz.
• Panel Voltage Stabilization Time
This time is the period that the TSC2014 allows for the touch screen to settle after turning on the
drivers.
• Precharge Time
• Sense Time
These two parameters show the time allowed to precharge the touch panel capacitance and then
sense to see if the screen has been touched. For more details about these parameters, see the
TSC2014 data sheet.
• Detection of Pen Touch in Wait
This option is valid when the ADC is put into the host-controlled mode. Enabling this option puts the
touch detection in the background and allows the TSC2014 to pull its PINTDAV pin high if no touch is
detected while waiting for the host to issue a command, so that the host can decide whether or not a
reading touch data command should be issued.
• Longer Sample Mode
Enabling this option adds an extra 500 ns of sampling time to the normal sampling cycle. It is disabled
by default.

7.3.2
www.ti.com
Test Mode Configuration (CFR1)
The TSC2014 features a touch screen test function to check if the four-wire touch panel has been properly
connected and if there is short-circuitry enabled. To perform the connection test, the resistance range of
the touch screen must be entered into CFR1. Select Short Circuit Panel Test to perform the short-circuitry
test function.
To perform a touch screen test, the Converter Function Selection must be set up in CB1 as X-Axis
Connection Test, Y-Axis Connection Test, or Short-Circuit Test. The multiple selector under CFR1
provides user access.
The test result returns to the Status Register.
Another TSC2014 feature is the Batch Delay Mode, as shown in the CFR1 section. Under the
TSC-controlled ADC mode, this feature adds a delay between ADC samples and thus controls the
time/interval between samples. The batch delay ranges from 0 ms to 100 ms.
7.3.3
MAVF Configuration (CFR2)
The preprocessing MAV filter (MAVF) within the TSC2014 reduces sampling noise. See the TSC2014
data sheet for details of the MAVF.
The CFR2 section has five selection buttons that can be used to enable/disable the MAVF on touch data,
X, Y, and Z, or nontouch data, AUX and Temperature.
Clicking on the MAV Filter Control option box brings up a list of settings on M and W values. Select an
eligible option from the list (do not select the Reserved option) and the corresponding digital value
appears in the next box. Click on the digital box to write the selected value to the CFR2 Register.
7.3.4
Threshold Configuration
Zone detection is one of the new features the TSC2014 offers. The zone detection function was designed
to monitor the zone/range of the nontouch inputs, including AUX and TEMP1/TEMP2.
The four control registers on the TSC2014 (used to set up the upper and lower thresholds of AUX and
TEMP1/TEMP2) can be accessed through the four moving slides in the Threshold Selection section. The
zone detection modes can be controlled/selected through the two option boxes at the bottom of the CFR2
section.

Command Line Interface Tab
Clicking on the Command Line Interface tab brings up a screen similar to that shown in Figure 5, which
provides a flexible way to read from and write to the TSC2014EVM by the use of scripts.
Figure 5. TSC2014EVM-PDK Software GUI: Command Line Interface Tab
The line or lines of the script are typed or loaded into the Command Buffer. Clicking on the Execute
Command Buffer button runs the script. (The script is discussed in Section 7.4.1.)
There are three LEDs on this tab. The req done LED lights up (that is, it turns green) after the script
execution finishes. If a line of the script is a reading command, the read data is shown at the Read Data
section; if the line of the script is a writing command, the written data bytes also are returned to the Read
Data section.

As Figure 6 shows, three read buttons reveal the contents of the Threshold, Control, and Status Registers
of the TSC2014; these contents are also displayed in the Data Read/Written section of the screen. The
data flow shows at the top of the screen, and is interpreted and listed correspondingly on the button. For
example, Figure 5 shows a read result of the four TSC2014 threshold registers after clicking on the Read
All (4) Control Registers button.

7.4.1
Software Script
The TSC2014EVM-PDK software was designed to identify and decipher several scripting commands, as
described in Table 5.
Table 5. Script Command Types
Command Type
Description
w
Write to TSC through the I2C serial control bus
r
Read from TSC through the I2C serial control bus
#
Comment line
b
Break
d
Delay
Each line in a script file is a command, and a line is terminated by a carriage return.
• The first character of a command line indicates the command type. Table 5 lists all the command types
that can be recognized and implemented by the TSC2014EVM-PDK software.
• Following the command type w or r, the byte is the I2C device address. For the TSC2014, this address
is either [1001 00A0R/W]b where A0 is 0b by default and can be changed by JP3; the LSB R/W is '1' if
a read command or '0' if a write command.
No byte follows a # (comment) or a b (break) command.
The byte or bytes following a command type d is the delay time in milliseconds (ms).
• The second byte in a w or r command line is the address of the TSC2014 configuration register. Refer
to the TSC2014 data sheet for details of the register address.
In an r command, the byte after the TSC2014 register address indicates the number of registers reading
from; the next byte is ignored. If more than one register must be read, the next byte is the address and is
followed by two dummy bytes that are ignored.
In a w command, the two bytes after the register address are the data written to the 16-bit TSC2014
registers. If more than one registers must be written, the next byte is the register address, followed by two
data bytes.
For writing to CB1 of the TSC2014, this byte includes both address and content; thus, there are no further
bytes after this address byte.

7.4.4.1
Log Script and Results
Go into the File menu and select Log Script and Results ..., which opens a file-select window and allows
you to specify a log file to write the script and results to. At this point, the script to read/write and the
results start to be logged into the file. For example, a written script is logged into the file for any action
performed on the Configuration Tab (see Section 7.3); a reading script and the reading results are logged
into the file if one of the read buttons on the Command Line Interface Tab (refer to Section 7.4) is clicked.
7.4.4.2
Log Data to File
Go into the File menu and select Log Data to File ..., which opens a file-select window and allows you to
specify a log file to write the data to. At the same time, this option enables the Datalogging menu.
When ready to begin recording data to a file, select Datalogging→Start Logging. Data are written to the
file until Datalogging→Stop Logging is selected. When the screen is not touched, the AUX, TEMP1, and
TEMP2 values are written to the file; the X, Y, Z1, and Z2 parameters are written to the file with values of
9999, to indicate that they are not updated. When the screen is touched, the X, Y, Z1, and Z2 parameters
are written while the AUX, TEMP1, and TEMP2 values are written to the file as 9999.
The format of the data file has the first column as the time in milliseconds (this value is only a timer in the
program, and can arbitrarily start at any number); then X, Y, Z1, Z2, AUX, TEMP1, and TEMP2 columns
follow. Every new reading is a new row in the file.
After selecting the Start Logging option , the data are constantly updated, and the datalog file can quickly
grow large. Therefore, log only necessary data.
