When power is supplied to J3, JMP5 allows for one of three different DC voltages to be selected as power
for the TSC. See the schematic and PCB silkscreen for details.
The TSC2003EVM-PDK motherboard (the USB-MODEVM Interface board) supplies power to J3 of the
TSC2003EVM. Power for the motherboard is supplied either through its USB connection or via terminal
blocks on the board.
4.1
TSC Power
Power for the TSC2003 VCC can be supplied either from the +5VD terminal or from the +3.3VD terminal.
JMP5 selects which of these voltages is routed to the TSC2003. When JMP5 is in the default factory
condition (shunt on pins 3-4), power to the TSC comes from J3.9 (+3.3VD). When the shunt is installed on
JMP4 pins 5-6, power comes from J3.10 (+5VD). A shunt on JMP4 pins 1-2 connects power to J3.8, an
unspecified voltage level that the user may supply.

EVM Operation
4.2
Stand-Alone Operation
When used as a stand-alone EVM, power can be applied to TP2, referenced to TP1.
CAUTION
Verify that all power supplies are within the safe operating limits shown on
the TSC2003 data sheet before applying power to the EVM.
4.3
USB-MODEVM Interface Power
The USB-MODEVM Interface board can be powered from several different sources:
• USB
• 6VDC-10VDC AC/DC external wall supply (not included)
• Lab power supply
When powered from the USB connection, JMP6 should have a shunt from pins 1-2 (this is the default
factory configuration). When powered from 6V-10VDC, 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 lab supplies are used to provide the individual voltages required by the USB-MODEVM Interface, JMP6
should have no shunt installed. Voltages are then applied to J2 (+5VA), J3 (+5VD), J4 (+1.8VD), and J5
(+3.3VD). The +1.8VD and +3.3VD can also be generated on the board by the onboard regulators from
the +5VD supply; to enable this supply, the switches on SW1 need to be set to enable the regulators by
placing them in the ON position (lower position, looking at the board with text reading right-side up). If
+1.8VD and +3.3VD are supplied externally, disable the onboard regulators by placing SW1 switches in
the OFF position.
Each power supply voltage has an LED (D1-D7) which will light when the power supplies are active.
4.4
Reference Voltage
The TSC2003 has an internal voltage reference. An external reference may be supplied through pin 20 of
J1 on the TSC2003EVM, referenced to analog ground (pin 18 of J1 on the TSC2003EVM). JMP1 must be
installed in order to route this external reference voltage to the TSC2003.
CAUTION
Verify that the external reference voltage is within the safe operating limits
shown on the TSC2003 data sheet before applying power to the EVM. Also,
program the TSC2003 to use an external reference, if one is used.

EVM Operation
The following section provides information on the analog input, digital control, and general operating
conditions of the TSC2003EVM.
5.1
Analog Input
The analog input sources (touch screen, auxiliary inputs, and battery inputs) can be applied directly to J1

The USB-MODEVM Interface board is intended to be used in USB mode, where control of the installed
EVM is accomplished using the onboard USB controller device. Provision is made, however, for driving all
the data buses (I2C, SPI™, I2S/AC97) externally. The source of these signals is controlled by SW2 on the
USB-MODEVM.
6.2
Quick Start
Ensure that the TSC2003EVM is installed on the USB-MODEVM Interface board. The TSC2003EVM
should be installed in the topmost position, using J11, J12, and J13 on the USB-MODEVM.
Place the CD-ROM into your PC CD-ROM drive. Locate the Setup program on the disk, and run it. The
Setup program will install the TSC2003 Evaluation software on your PC.

Runtime, a self-extracting archive. Click OK to proceed. A WinZip™ dialog appears. Click Unzip, and the
archive extracts itself and automatically runs the NI-VISA 3.2 Runtime installer.
Follow the instructions in the NI-VISA 3.2 Runtime Installer. When prompted for which features to install,
do the following:
1. Click on the disk icon next to NI-VISA 3.2
2. Select, Do not install this feature.
3. Click on the disk icon next to USB.
4. Select the option which installs this feature.
5. Click Next.
Accept the license agreement, and continue the installation.
When the installation completes, click Finish on the TSC2003EVM installer window. You may be prompted
to restart your computer.
When installation is complete, attach a USB cable from your PC to the USB-MODEVM Interface board. As
configured at the factory, the board will be powered from the USB interface, so the power indicator LEDs
on the USB-MODEVM should light. Once this occurs, launch the TSC2003 Evaluation software on your
PC.
The software should automatically find the TSC2003EVM, and a screen similar to the one shown in
Figure 2 should appear.

In order to use the touch screen features, a 4-wire resistive touch screen will need to be connected to J1
of the TSC2003EVM, as described earlier.
6.3
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 built around a TAS1020B streaming audio USB controller with an 8051-based core.
The board features two positions for modular EVMs, or one double-wide serial modular EVM may be
installed.
For use with the TSC2003, the TSC2003EVM is installed in the topmost EVM slot, which connects the
TSC2003 digital control interface to the I2C port realized using the TAS1020B. Since the TSC2003 has no
audio features, the lower EVM slot, which is connected to the TAS1020B digital audio interface, is not
used.
As configured from the factory, the board is ready to use with the TSC2003EVM. However, if external SPI
control is desired, the signals may be applied to J15, as long as the SW2 is set so that USB SPI control is
disabled. To view all the functions and configuration options available on this board, see the
USB-MODEVM Interface Board schematic in Section 9.

Program Description
After the TSC2003EVM-PDK software installation (described in Section 6.2), evaluation and development
with the TSC2003 can begin.
6.4.1
Touch Screen Functions Panel
The touch screen box in this panel will be updated when a touch is detected on the touch screen. As the
touch screen is drawn upon, the motion on the touch screen will be translated into pixels on this box. The
software takes X, Y, and Z readings which are shown to the right of the touch screen box. As the touch
pressure is increased, the pixel size increases; a lighter touch results in smaller pixel sizes.
The Z-value displayed is not what is described in the TSC2003 data sheet, because in the data sheet
equation, it is assumed that the sheet resistance of the touch screen being used is known. The value used
in this program is calculated by Equation 2 of the TSC2003 data sheet, but without multiplying it by the
RX-plate resistance. This value ranges from 0 to 3, and larger, with smaller 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 display
of spurious points that may result from touch screen mechanical bouncing.
The display can be cleared by pressing the Clear Graph button on the screen.
6.4.2
Data Acquisition Functions Panel
The TSC2003 has provision for measuring two battery voltages (VBAT1 and VBAT2), two auxiliary input
voltages (AUX1 and AUX2), and temperature. This panel displays the measured values for these
parameters. Measurements are updated only when the touch screen is not being pressed.
Temperature is displayed using both methods described in the TSC2003 data sheet. Using the TEMP0
and TEMP1 measurements, a temperature reading with 2°C resolution and accuracy is achieved. Using
only the TEMP0 measurement, a reading with 0.3°C resolution is possible, but this option requires
knowing the TEMP0 value at +25°C; this would normally be a calibration that the user would perform. This
program assumes that TEMP0 = 600mV at +25°C.
6.4.3
Configuration Panel
The TSC2003 can be configured to operate in 8-bit or 12-bit resolution modes. Control over the mode
used is selected in this panel.
In the middle of this panel is an indicator light that shows the I2C Bus Status. If the TSC2003 is
acknowledging the address sent, the light is green; if the TSC2003 cannot acknowledge, the light is red.
The address that the TSC2003 is set to is shown in binary format in the box labeled, Device Address
A1-A0. The address set here should correspond to the bit settings determined by JMP3 and JMP4 on the
TSC2003EVM.
The two power-down bits of the TSC2003 can be set from this panel as well. A brief description of the
mode selected is shown on the screen when setting these bits; see Table II (Power-Down Bit Functions)
of the TSC2003 data sheet for details on what these bits do.
6.4.4
Datalogging
The software can record the data it takes from the TSC2003 to a tab-delimited file, suitable for importing
into spreadsheets. To do this, first go into the File menu, and select Log Data to File..., which opens a
file-select window and allows you to specify a file to which to write the data. At the same time, this enables
the Datalogging menu.
When ready to begin recording data to a file, select Datalogging → Start Logging. Data is written to the file
until Datalogging → Stop Logging is selected. When the screen is not touched, the VBAT1, VBAT2,
AUX1, AUX2 and TEMP values are written to the file, and 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 VBAT1, VBAT2, AUX1, AUX2 and TEMP values are written
to the file as 9999. Because the program constantly updates at a rate of about 400 readings per second,
datalog files can quickly grow large; therefore, log only that data which is necessary.

The format of the data file has the first column as the time in milliseconds (which is just a timer in the
program; it can arbitrarily start at any number), then X, Y, Z1, Z2, VBAT1, VBAT2, AUX1, AUX2, TEMP0,
and TEMP1 columns. Every new reading is a new row in the file.

questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 30 °C. The EVM is designed to
operate properly with certain components above 85 °C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
