When power is supplied to J3, JP1 allows for one of two different dc voltages to be selected as the power
source for the TSC. See the schematic and PCB silkscreen for details.
The TSC2017EVM-PDK motherboard (the USB-MODEVM interface board) supplies power to J3 of the
TSC2017EVM. 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 TSC2017 VDD can be supplied either from the +1.8-VD terminal or from the +3.3-VD
terminal.
JP1 selects the voltage that is routed to the TSC2017. When JP1 is in the default factory condition (shunt
on pins 1-2), power to the TSC comes from J3.9 (+3.3 VD). When the shunt is installed on JP1 pins 2-3,
power comes from J3.7 (+1.8 VD). Removing the shunt on JP1, the user can connect any dc power
supply between 1.6 VD and 3.6 VD to VCC by connecting the power to JP1 pin 2.

Standalone Operation
When used as a standalone EVM, power can be applied to TP1 (VCC), referenced to TP3 (AGND).
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
TSC2017 data sheet (SBAS472) 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 to 10-VDC ac/dc external wall supply (not included)
• Laboratory power supply
When powered from the USB connection, JMP6 must have a shunt from pins 1-2 (this is the default
factory configuration). When powered from 6 VDC to 10 VDC, either through the J8 terminal block or J9
barrel jack, JMP6 must 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.

EVM Operation
www.ti.com
If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM interface
board, JMP6 must have no shunt installed. Voltages then are 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 by the onboard regulators from
the +5-VD supply; to enable this supply, the switches on SW1 must 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 +1.8
VD and +3.3 VD are supplied externally, disable the onboard regulators by placing SW1 switches in the
OFF position.
Each power supply voltage has an LED (D1-D7) that lights when the power supplies are active.

EVM Operation
This section provides information on the analog input, digital control, and general operating conditions of
the TSC2017EVM.
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 TSC2017EVM
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 TSC2017EVM-PDK. See the device product folder for the
TSC2017 for a current list of compatible interface and/or accessory boards.

The simple diagram 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 TSC2017, the TSC2017EVM is installed in the topmost EVM slot, which connects the
TSC2017 digital control interface to the I2C port, realized using the TAS1020B. Because the TSC2017 has
no audio features, the lower EVM slot, which is connected to the TAS1020B digital audio interface, is not
used.

You are done and ready to run the TSC2017EVM software GUI.
6.2
Quick Start
In order to use the touch screen features, a four-wire resistive touch screen must be connected to J1 on
the TSC2017EVM. It is important to ensure that the connection between TSC2017 and the touch screen is
as short, simple, and secure as possible.
When both hardware and software installation/setup have completed successfully, attach a USB cable
from your PC to the USB-MODEVM Interface board (J7 on the motherboard). As configured at the factory,
the board is powered from the USB interface; no other external power supply is needed, and the power
indicator LEDs on the USB-MODEVM light up.
Also the yellow LED (D2, which is located next to the J7 USB plug) lights up to indicate that the processor
on the USB-MODEVM board works and runs the TSC firmware program properly.
Launch the TSC2017 evaluation software on your PC, which you just installed. The software automatically
finds the TSC2017EVM, and a screen similar to the one shown in Figure 2 appears.

www.ti.com
Note that the I2C Bus Status shown in the lower right corner (just above the STOP button of the GUI in
Figure 2) is green if the driver in your PC has been properly set up, and the TSC slave address is
corresponding.
TSC2017 has an address pin A0 that can be set low or high to get the TSC2017 address for either
1001000b (if A0 = low) or 1001001b (if A0 = high). On the TSC2017EVM board, JP3 controls the A0
status. By default, A0 must be installed (refer to Table 5), and thus the default A0 is '0' in the Device
Address (A0) selection box. Change it to '1' if TSC2017EVM JP3 is removed (high).
At the startup of the GUI, the non-Touch Data Acquisition section (on the right side) functions and proper
temperature data is displayed, as shown in Figure 2.
To stop running the software, you click on the STOP button in the lower right corner of the screen.
6.3
GUI and Operation Description
After the TSC2017EVM-PDK hardware and software installation and setup (described in Section 6.1),
evaluation and development with the TSC2017 can begin.
By plugging into a USB port on your PC and starting the TSC2017EVM-PDK software on your PC, the
interface GUI is displayed as shown in Figure 2.
The GUI has four general sections (shown in Figure 3):
1. The yellow boxes contain Touchscreen Functions.
2. The blue box contains Data Acquisition Functions.
3. The pink box contains TSC2017 commands.
4. The purple box contains TSC2017 Setup commands.

www.ti.com
Figure 3. Four Main Sections in TSC2017EVM-PDK GUI Screen
6.3.1
Touchscreen Functions
The Touchscreen Functions section 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 TSC2017 data sheet; this difference is 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 TSC2017 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 pressure 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.

6.3.2
Data Acquisition Functions
The TSC2017 has provision for measuring one auxiliary input voltages (AUX) and temperature. This
section displays the measured values for these parameters. Measurements are updated only when the
touch screen is not being pressed and auto-reading mode is enabled (the AutoRead LED button is on).
Temperature is displayed using both methods described in the TSC2017 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 = 580 mV at 25°C.
By default, AutoRead LED is on. That is, the software continuously reads nontouch data, AUX, TEMP1
and TEMP2, and automatically updates them in the Non-Touch Data Acquisition section. To stop the data
acquisition, click on the green LED AutoRead to turn it off.
Both AUX and temperature measurements require a reference voltage, which is provided to the TSC2017
VREF pin. The VREF (volts) controller box can be written with the corresponding VREF voltage. The factory
default VREF is 3.3 VDC.
6.3.3
TSC2017 Command
The TSC2017 can be configured to operate in 8-bit or 12-bit resolution modes. Control over the mode
used is selected in this section, which is sent to TSC2017 in the command byte.
The two power-down bits, PD1 and PD0, of the TSC2017 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 2 (Command
Byte Definitions) of the TSC2017 data sheet (SBAS472) for details on what these bits do.
6.3.4
TSC2017 Setup Command
TSC2017 has several software programmable features that can be set up by TSC2017 in the setup mode,
a specific command called Setup.
Software reset can bring TSC2017 to its power-up default condition. When clicking on the LED and it
becomes green, the TSC2017 is software reset.
TSC2017 has a built-in MAV filter, which is enabled by default. The MAV filter can be disabled/enabled by
clicking on the MAV Filter button.
The PENIRQ signal from the TSC2017 can be used as an interrupt to the host, and it requires being
pulled up by a resistor. The TSC2017 has an internal pullup RIRQ, and thus no external pullup is needed.
The internal pullup RIRQ can be selected and programmed to be 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 and Setup mode of the TSC2017, see the product data
sheet (SBAS472), .
6.3.5
TSC2017 Hardware Reset
Clicking on the Hardware Reset LED in the lower right corner of the GUI turns the LED switch on or off.
When the LED is turned on or lit (in green), the hardware reset pin RESET is pulled low by a digital control
signal from the USB-MODEVM board, and the TSC2017 enters the hardware reset process. To bring
TSC2017 back to normal operational state, the LED must be turned off.
6.4
Datalogging
The software can record the data it takes from the TSC2017 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.

www.ti.com
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 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 approximately 400 readings per second, datalog files can quickly grow
large; therefore, log only that data which are 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.

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 0 V to 3.6 V and the output voltage range of 0 V to 3.6 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.
