When power is supplied to J3, JMP1 allows for one of two different DC voltages to be selected as power
for the TSC. See the schematic and PCB silkscreen for details.
The TSC2008EVM-PDK motherboard (the USB-MODEVM interface board) supplies power to J3 of the
TSC2008EVM. 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 TSC2008 VDD can be supplied either from the +1.8VD terminal or from the +3.3VD terminal.
JMP1 selects which of these voltages is routed to the TSC2008. When JMP1 is in the default factory
condition (shunt on pins 2-3), power to the TSC comes from J3.9 (+3.3VD). When the shunt is installed on
JMP1 pins 1-2, power comes from J3.7 (+1.8VD). Removing the shunt on JMP1, the user can connect
any DC power supply between 1.2VD and 3.6VD to VCC by connecting the power to JMP1 pin 2.

When used as a stand-alone EVM, power can be applied to TP6 (VDD), referenced to TP12 (GND).
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
TSC2008 data sheet (SBAS406) 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-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 (this is the default
factory configuration). When powered from 6VDC-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 then are applied to J2 (+5VA), J3 (+5VD), J4
(+1.8VD), and J5 (+3.3VD). The +1.8VD and +3.3VD also can 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 lights when the power supplies are active.

EVM Operation
The following section provides information on the analog input, digital control, and general operating
conditions of the TSC2008EVM.
5.1
Analog Input
The analog input sources (touch screen and auxiliary input) can be applied directly to J1 (top or bottom
side) 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). The modular TSC2008EVM
also can be connected directly to a DSP or microcontroller interface board, such as the USB-MODEVM
interface board if purchased as part of the TSC2008EVM-PDK. See the product folder for the TSC2008 for
a current list of compatible interface and/or accessory boards.

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. However, provision is made for driving all
the data buses (I2C, SPI™, and I2S/AC97) externally. The source of these signals is controlled by SW2 on
the USB-MODEVM.
6.2
Quick Start
Before installing the TSC2008EVM board on top of the USB-MODEVM board, check SW2-1, SW2-2, and
SW2-3 on the USB-MODEVM board to ensure that at least one of these three is OFF
Ensure that the TSC2008EVM is installed on the USB-MODEVM interface board. The TSC2008EVM
should be installed in the topmost position, using J11, J12, and J13 on the USB-MODEVM.

Place the CD-ROM into your personal computer (PC) CD-ROM drive. Locate the Setup program on the
disk, and run it. The Setup program installs the TSC2008 Evaluation software on your PC.
Accept the license agreement, and continue the installation.
When the installation completes, click Finish on the TSC2008EVM 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 is powered from the USB interface; so, the power indicator LEDs on
the USB-MODEVM should light. Once this occurs, launch the TSC2008 evaluation software on your PC. It
is suggested that users read the readme_install.txt file for up-to-date, step-by-step instructions.
The software should automatically find the TSC2008EVM, and a screen similar to the one shown in
Figure 2 should appear.
Figure 2. Default Software Screen
In order to use the touch screen features, a user needs to connect a 4-wire resistive touch screen to J1 of
the TSC2008EVM, as described previously.

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 TSC2008, the TSC2008EVM is installed in the topmost EVM slot, which connects the
TSC2008 digital control interface to the SP1 port, realized using the TAS1020B. Because the TSC2008
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 TSC2008EVM.
6.4
Program Description
After the TSC2008EVM-PDK software installation (described in Section 6.2), evaluation and development
with the TSC2008 can begin.
6.4.1
Touch Screen Functions Panel
The touch screen box in this panel is updated 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 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 TSC2008 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 TSC2008 data sheet, but without multiplying it by the
RX-plate resistance. This value ranges from 0 to 3, and larger, 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 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 TSC2008 has provision for measuring one auxiliary input voltages (AUX) 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 TSC2008 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 normally is a calibration that the user performs. This program
assumes that TEMP0 = 600 mV at +25°C.
6.4.3
Configuration Panel
The TSC2008 can be configured to operate in 8-bit or 12-bit resolution modes. Control over the mode
used is selected in this panel.
Touch screen measurements can be made in either single-ended or differential mode; see the TSC2008
data sheet for a discussion of these modes. The touch screen measurement mode can also be selected in
this panel. If single-ended mode is used, an external reference is highly recommended; however,
single-ended measurements are discouraged for touch screen use because differential mode yields far
more accurate results.
The two power-down bits of the TSC2008 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 3 (Command Byte Definitions)
of the TSC2008 data sheet (SBAS406) for details on what these bits do.

6.4.4
Setup Panel
TSC2008 has several software programmable features that can be set up by TSC2008 in the setup mode,
when A[2:0] = 2h.
Software reset can bring TSC2008 to its power-up default condition. When clicking on the LED and it
becomes green, the TSVC2008 is software reset.
TSC2008 can be totally compatible to TSC2046 on their data protocols, that is: the MSB of MISO signal
from the TSC starts at the falling edge of the ninth SCLK, that is: the SDO data is readable from the rising
edge of the tenth SCLK. Besides, TSC2008 can have its SDO output readable from the rising edge of the
ninth SCLK. This option can be selected by clicking on the TSC2046 Timing button. TSC2008 output
starting from the tenth SCLK when the TSC2046 Timing is enabled; and TSC2008 outputs starting from
the ninth SLK when the TSC2046 Timing is disabled. TSC2008 is defaulted with the TSC2046 Timing
being enabled.
TSC2008 has a built-in MVA filter, which is enabled by default. The MV filter can be disabled/enabled by
clicking on the MVA Filter button.
The PENIRQ can be used as an interrupt to the host and is pulled up by RIRQ internally. The RIRQ is with a
programmable value of either 50 kΩ (default) or 90 kΩ. The Internal PENIRQ Pullup button is used to
select the RIRQ.
For more details on the programmable features, see the data sheet.
6.4.5
Datalogging
The software can record the data it takes from the TSC2008 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 AUX 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 AUX 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, AUX, TEMP0, and TEMP1 columns.
Every new reading is a new row in the file.

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.
