When power is supplied to J3, JMP1 allows for one of two different DC voltages to be selected as powerfor the TSC. See the schematic and PCB silkscreen for details.
The TSC2007EVM-PDK motherboard (the USB-MODEVM interface board) supplies power to J3 of theTSC2007EVM. Power for the motherboard is supplied either through its USB connection or via terminalblocks on the board.
Power for the TSC2007 VCC can be supplied either from the +1.8VD terminal or from the +3.3VDterminal. JMP1 selects which of these voltages is routed to the TSC2007. When JMP1 is in the defaultfactory condition (shunt on pins 2-3), power to the TSC comes from J3.9 (+3.3VD). When the shunt isinstalled on JMP1 pins 1-2, power comes from J3.7 (+1.8VD). Removing the shunt on JMP1, the user canconnect any DC power supply between 1.2VD and 3.6VD to VCC by connecting the power to JMP1 pin 2.

EVM Operation
When used as a stand-alone EVM, power can be applied to TP1, referenced to TP3.
CAUTION
Verify that all power supplies are within the safe operating limits shown on theTSC2007 data sheet (SBAS405 ) before applying power to the EVM.
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 defaultfactory configuration). When powered from 6 VDC-10 VDC, either through the J8 terminal block or J9barrel 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 interfaceboard, 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 onboardregulators from the +5VD supply; to enable this supply, the switches on SW1 need to be set to enable theregulators by placing them in the ON position (lower position, looking at the board with text readingright-side up). If +1.8VD and +3.3VD are supplied externally, disable the onboard regulators by placingSW1 switches in the OFF position.
Each power supply voltage has an LED (D1-D7) which lights when the power supplies are active.
The following section provides information on the analog input, digital control, and general operatingconditions of the TSC2007EVM.
The analog input sources (touch screen and auxiliary input) can be applied directly to J1 (top or bottomside) or through signal-conditioning modules available for the modular EVM system.
The digital control signals can be applied directly to J2 (top or bottom side). The modular TSC2007EVMalso can be connected directly to a DSP or microcontroller interface board, such as the USB-MODEVMinterface board if purchased as part of the TSC2007EVM-PDK. See the product folder for the TSC2007 fora current list of compatible interface and/or accessory boards.
Table 6 provides a list of jumpers found on the EVM and their factory default conditions.

Kit Operation
Place the CD-ROM into your PC CD-ROM drive. Locate the Setup program on the disk, and run it. TheSetup 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 promptedto restart your computer.
When installation is complete, attach a USB cable from your PC to the USB-MODEVM interface board. Asconfigured at the factory, the board is powered from the USB interface; so, the power indicator LEDs onthe USB-MODEVM should light. Once this occurs, launch the TSC2007 evaluation software on your PC. Itis 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 inFigure 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 ofthe TSC2007EVM, as described previously.

6.4.2 Data Acquisition Functions Panel
6.4.3 Configuration Panel
Kit Operation
The simple diagram shown in Figure 1 shows only the basic features of the USB-MODEVM interfaceboard. 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 beinstalled.
For use with the TSC2007, the TSC2007EVM is installed in the topmost EVM slot, which connects theTSC2007 digital control interface to the I
2
C port, realized using the TAS1020B. Because the TSC2007 hasno audio features, the lower EVM slot, which is connected to the TAS1020B digital audio interface, is notused.
As configured from the factory, the board is ready to use with the TSC2007EVM except for SW2, in whichcase at least one of SW2-1, SW2-2, and SW2-3 must be set to OFF.
After the TSC2007EVM-PDK software installation (described in Section 6.2 ), evaluation and developmentwith the TSC2007 can begin.
The touch screen box in this panel is updated when a touch is detected on the touch screen. As the touchscreen is drawn on, the motion on the touch screen is translated into pixels on this box. The softwaretakes X, Y, and Z readings which are shown to the right of the touch screen box. As the touch pressure isincreased, 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 sheetequation, it is assumed that the sheet resistance of the touch screen being used is known. The value usedin this program is calculated by Equation 2 of the TSC2007 data sheet, but without multiplying it by theR
X-plate
resistance. This value ranges from 0 to 3, and larger, with larger numbers representing a moreforceful press on the screen. Using the Maximum Z Value to Display knob, you can set a threshold sothat the program does not display lightly pressed points. This threshold setting helps to eliminate displayof spurious points that may result from touch screen mechanical bouncing.
The display can be cleared by pressing the Clear Graph button on the screen.
The TSC2007 has provision for measuring one auxiliary input voltages (AUX1) and temperature. Thispanel displays the measured values for these parameters. Measurements are updated only when thetouch screen is not being pressed.
Temperature is displayed using both methods described in the TSC2007 data sheet. Using the TEMP0and TEMP1 measurements, a temperature reading with 2°C resolution and accuracy is achieved. Usingonly the TEMP0 measurement, a reading with 0.3°C resolution is possible, but this option requiresknowing the TEMP0 value at +25°C; this would normally be a calibration that the user would perform. Thisprogram assumes that TEMP0 = 600 mV at +25°C.
The TSC2007 can be configured to operate in 8-bit or 12-bit resolution modes. Control over the modeused is selected in this panel.
In the middle of this panel is an indicator light that shows the I
2
C Bus Status. If the TSC2007 isacknowledging 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 AddressA1-A0. The address set here should be "00" when using the TSC2007EVM. Even though the TSC2007has two pins, A0 and A1, for users to select four different I2C addresses, the TSC2007EVm has only afixed address 1001000b, where A0=A1="0", because both A0 and A1 are tied to ground. See theTCS2007EVM schematic provided in this document.

6.4.4 Datalogging
7 EVM Bill of Materials
EVM Bill of MaterialsThe two power-down bits of the TSC2007 can be set from this panel as well. A brief description of themode 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.
The software can record the data it takes from the TSC2007 to a tab-delimited file, suitable for importinginto spreadsheets. To do this, first go into the File menu, and select Log Data to File..., which opens afile-select window and allows you to specify a file to which to write the data. At the same time, this enablesthe Datalogging menu.
When ready to begin recording data to a file, select Datalogging →Start Logging. Data is written to the fileuntil Datalogging →Stop Logging is selected. When the screen is not touched, the AUX and TEMP valuesare written to the file, and the X, Y, Z1, and Z2 parameters are written to the file with values of 9999, toindicate that they are not updated. When the screen is touched, the X, Y, Z1, and Z2 parameters arewritten while the AUX and TEMP values are written to the file as 9999. Because the program constantlyupdates at a rate of about 400 readings per second, datalog files can quickly grow large; therefore, logonly 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 theprogram; 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.
