Deepika,

My guess is there is some security control in your browser is stripping off the zip file extension. Please add ".zip" to the file name and open it.

thanks for replying. i have installed software. 

now my second problem is that i want to communicate tdc7200 evalution  board with arduino instead of your MSP430 Touch pad.i have made a c code on arduino software using spi interfacing. but i am unable tor read registers of tdc7200 it shows zero values in registers.

plz help me to solve regarding this issuue. i am pasting my c code below.

Please probe the SPI bus and check if the Chip Select, Clock, Data In and Data Out signals are happening. Is the CS going down? Do you see the clock from MCU happening? Do you see the address written correctly? Please attach a scope shot.

Check all the connections between Arduino and TDC7200EVM. Make sure power is there. Also, check if the TDC7200EVM 8MHz clock is happening. What's the supply voltage for Arduino? TDC7200 cannot take 5V signals.

Please check this user guid

Section 5 explains installing the GUI , uploading firmware to the launch pad, and checking the connection.

Thanks,
Vishy

TDC7200 has a feature to blank or ignore stop pulses for a defined period using CLOCK_CNTR_STOP_MASK_H/L registers. In this case, TDC7200 will start looking for STOP pulses after this defined period. This period is applied after START is received so TDC7200 will ignore any STOP pulses occurring from START to the expiration of this period. It cannot be used for in-between STOP pulses.

Please check the MSP430 sample code released with the TDC7200EVM GUI. You can find the TDC7200EVM firmware source code in the following folder

C:\Program Files (x86)\Texas Instruments\TDC720xEVM\Firmware

For use with launchpad you can get TI CCS toolset free and launchpad has built-in JTAG so you can download and debug through the USB port itself. The zip file has project files for CCS as well as IAR. You will find a basic spi read/write project that illustrates TDC7200 register read/write from MSP430.

You can see some general getting started tips here
