laptop for evaluation. A complete circuit description, schematic diagram, and bill of materials are included
in this document.
The following related documents are available through the Texas Instruments web site at www.ti.com.
The following lists devices and corresponding device data sheets of devices that are compatible with this
EVM:
• TSC2013, SLVSC89
• DRV2605, SLOS825
• REG1117-33, SBVS001
• MSP430F247, SLAS547I

J202.6 GND
J201.1 RXD_Debug Receiving asynchronous data input. For debug purpose.
J201.2 GND
J201.3 TXD_Debug Transmit Asynchronous Data Output. For debug purpose.
5 Power Supplies
The USB connection supplies the TSC2013EVM with power. Onboard regulators generate the required
supply voltages and no further power supplies are necessary. The power-supply voltage has an LED
(LED502) that lights up when the power supplies are active.
6 EVM Operation
The following section provides information on the analog input, digital control, and general operating
conditions of the TSC2013EVM.
6.1 Analog Input
The analog input sources (touch screen) can be applied directly to pin J300.
6.2 Digital Control
The digital control signals are applied through the USB connection and no other connections are required.
The TSC2013EVM can also be connected to a DSP or microcontroller interface board through the J202
pin. If external I2C control is desired, remove the following resisters: R231, R232, and R233.

The following section provides information on using the TSC2013EVM, including setup, program
installation, and program usage.
7.1 TSC2013EVM-PDK Block Diagram
Figure 1 shows a block diagram of the TSC2013EVM. The TSC2013 and DRV2605 device are both
controlled by an MSP430™ microcontroller (MCU) through an I2C interface. One resistive touch panel is
connected to the TSC2013 device by a 4-pin FPC connector and an LRA motor is attached as an
actuator. The FT232 device is a USB-to-serial UART interface and is used to transfer data from the
MSP430 MCU to the host PC or is used to receive commands from the host PC.

Kit Operation www.ti.com
7.2 Quick Start
Place the CD-ROM into CD-ROM drive of the PC. Locate the Setup.exe program on the disk and execute
the program. The setup program installs the TSC2013 evaluation software on the PC. Follow the
instructions and prompts given to correctly install the software.
After the software is installed, a dialog box appears with instructions for installing the FTDI CDM drivers
which are a self-extracting archive. Click the Extract button to proceed. The archive extracts the files and
automatically runs the installer for the FTDI CDM Drivers which is shown in Figure 2.
When the driver installation is complete, attach a USB cable from the PC to the TSC2013EVM board. The
board receives power from the USB interface and therefore the power-indicator LED (LED502) on the
TSC2013EVM should light up when the USB cable is attached. When the USB cable is connected to the
PC and the EVM board, launch the TSC2013 evaluation software on the PC. A screen similar to the one
in Figure 4 should appear when the software is launched.

Figure 4. Default Software Screen
In order to use the touch-screen features, a 4-wire resistive-touch screen must be connected to the J300
pin of the TSC2013EVM, as previously described.
Click the Serial Settings button and the window shown in Figure 3 opens. Select the correct port and click
the OK button. Click the Connect button and the word Connected appears with a green background in the
bottom left of the screen. Figure 4 shows the word Disconnected with a red background.
If the port number is unknown, navigate to the PC Device Manager from the Control Panel that is located
on the Start Menu of a PC running a Windows OS. Expand the Ports (COM & LPT) list to view the ports.
Select the port that has an annotation beginning with USB Serial Port as shown in Figure 5.

7.3 Program Description
After the TSC2013EVM software is installed, the EVM board can be used to evaluate and develop the
TSC2013 device.
7.3.1 1-Finger Trace Panel
The touch-screen box in the 1-Finger Trace Panel is updated when a touch is detected on the touch
screen (see Figure 6). When the touch screen is drawn on, the drawing motion on the touch screen is
translated into pixels on this box.
The display can be cleared by pressing the Clear button on the screen.
Figure 6. 1-Finger Trace Screen
7.3.2 2-Finger Gesture Panel
The TSC2013EVM supports three types of gestures which are zoom in or out, rotation, and 1-finger flick.
Pictures are updated when a gesture is detected by the firmware in the MSP430 device (see Figure 7).
For example, if a user performs a zoom in or zoom out gesture on the touch panel, the picture on the
screen zooms in or out at the same time that the gesture is performed.
