4.1 TSC Power

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 TSC2007EVM-PDK motherboard (the USB-MODEVM interface board) supplies power to J3 of the
TSC2007EVM. Power for the motherboard is supplied either through its USB connection or via terminal
blocks on the board.

Power for the TSC2007 VCC 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 TSC2007. 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.

EVM Operation

4.2 Stand-Alone Operation

When used as a stand-alone EVM, power can be applied to TP1, referenced to TP3.

Verify that all power supplies are within the safe operating limits shown on the
TSC2007 data sheet (SBAS405 ) 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

• 6 VDC-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 6 VDC-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.

CAUTION

5 EVM Operation

The following section provides information on the analog input, digital control, and general operating
conditions of the TSC2007EVM.

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 TSC2007EVM
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 TSC2007EVM-PDK. See the product folder for the TSC2007 for
a current list of compatible interface and/or accessory boards.

5.3 Default Jumper Locations

Figure 1. TSC2007EVM-PDK Block Diagram

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 TSC2007EVM 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 TSC2007EVM is installed on the USB-MODEVM interface board. The TSC2007EVM
should be installed in the topmost position, using J11, J12, and J13 on the USB-MODEVM.

Kit Operation

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 TSC2007 Evaluation software on your PC.

Accept the license agreement, and continue the installation.
When the installation completes, click Finish on the TSC2007EVM 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 TSC2007 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 TSC2007EVM, 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 TSC2007EVM, as described previously.

Kit Operation

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 TSC2007, the TSC2007EVM is installed in the topmost EVM slot, which connects the
TSC2007 digital control interface to the I2C port, realized using the TAS1020B. Because the TSC2007 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 TSC2007EVM except for SW2, in which
case at least one of SW2-1, SW2-2, and SW2-3 must be set to OFF.

6.4 Program Description

After the TSC2007EVM-PDK software installation (described in Section 6.2 ), evaluation and development
with the TSC2007 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 TSC2007 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 TSC2007 data sheet, but without multiplying it by the
R
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.

resistance. This value ranges from 0 to 3, and larger, with larger numbers representing a more

X-plate

6.4.2 Data Acquisition Functions Panel

The TSC2007 has provision for measuring one auxiliary input voltages (AUX1) 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 TSC2007 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 = 600 mV at +25°C.

6.4.3 Configuration Panel

The TSC2007 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 TSC2007 is
acknowledging the address sent, the light is green; if the TSC2007 cannot acknowledge, the light is red.
The address to which the TSC2007 is set is shown in binary format in the box labeled Device Address
A1-A0. The address set here should be "00" when using the TSC2007EVM. Even though the TSC2007
has two pins, A0 and A1, for users to select four different I2C addresses, the TSC2007EVm has only a
fixed address 1001000b, where A0=A1="0", because both A0 and A1 are tied to ground. See the
TCS2007EVM schematic provided in this document.

The two power-down bits of the TSC2007 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 TSC2007 data sheet (SBAS405 ) for details on what these bits do.

6.4.4 Datalogging

The software can record the data it takes from the TSC2007 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.

days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY
SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.

The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all
claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to
take any and all appropriate precautions with regard to electrostatic discharge.

EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER
FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.

TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of

patents or services described herein.

Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the
product. This notice contains important safety information about temperatures and voltages. For additional information on TI’s
environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh .

No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or

FCC Warning

This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and

can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.

EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 3.3 V to 5 V and the output voltage range of 0 V to 5 V.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are

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.
