CCS/PGA970EVM: EVM has no function and no activity on any pins (PGA970_FW_Release_1_5_Generic)
Part Number: PGA970
Tool/software: Code Composer Studio
I have buy PGA970 controller for programing i required Setup_PGA970_EVM.exe read from PGA970 GUI installation for running the PGA970EVM Controller. please share link for downloading the setup exe file.
also i want to know which CCS vrsion is applicable to run the firmware without any issue..
The PGA970EVM GUI should be available on the PGA970 mysecure page shortly. I recommend using the latest version of CCS when developing PGA970 firmware, but V6 or newer will work without issue.

Thanks for the reply,
currently I am using CCS Ver 7.4 which is having PGA family.
in that I have following issue
1) I am using USB2ANY debugger for putting the program into PGA 970 controller from CCS Ver 7.4 . but while putting the program into my development board I am not able to select the USB2ANY debugger for putting the program into the development board. I want to know that How to configure the USB2ANY for putting the program. also I have read all the user guide manual of PGA970 but I have not able to get any solution.
2) I am trying to install the Setup_PGA970_EVM but while installing the .exe I am getting an error that Version of PGA 970 we are trying to install is already installed in the system. thus the installer will exit.
I have check all the file related to Setup_PGA970_EVM.exe in C drive and in control panel but there are no related file please send the list of file that has been generate while the executing the setup.exe if any of the file is missed by me or how to remove this error so that installing .exe will be done .

Awaiting for your reply for Above message.
Also I want to know that USB2ANY can be used for debugging the PGA970EVM program from CCS Ver7.4
if Yes, then how to do wiring connection from USB2ANY to PGA970EVM evaluation board and how to get the debugger name will selecting the debugger from CCS7.4 for downloading the program into PGA970EVM evaluation board.
Thanks and regards,
The USB2ANY cannot be used for debugging with the PGA970. It is used only to communicate through I2C, SPI, or OWI between the PGA970EVM GUI and the PGA970EVM itself.
In order to debug in realtime using CCS, you will have to use an XDS200 JTAG emulator. The PGA970 Software Quickstart Guide describes how to connect and set up the XDS200 as a debugger with CCS. You can find the quickstart guide here: http://www.ti.com/lit/ug/sldu025/sldu025.pdf
Thanks Scott for the reply,
I want to that is there any another option to buy cheaper debugger than XDS200 for development.
if yes then please let me know?
At this time the XDS200 is the only supported debugger for the PGA970.
Current I am using PGA970EVM with USB2ANY also with PGA970 setup.exe for communication.
In that i am able to generate the sinewave in CRO using PGA Evaluation board and PGA970 software.
Output voltage is 14mV at TP16 and TP22 . Output waveform has been taken from TP70 and TP71.
But Now the waveform which i am getting is not constant i,e. its amplitude is constant but the sinewave width is varying with respect to time.
Varying of sinewave width is very fast. my whole operation depends on this sinewave if it is varying with respect to time.
then my measurement will also vary with respect to time.
Please Help me to get the stable sine wave at the TP70 and TP71 at the output.
also i have checked with both i,e. bypass the external amplifier or applying the external amplifier i am getting the same waveform at the Output in CRO.
Kindly give the reply of above message and also I want to know that in PGA970EVM Evaluation Module with USB2ANY using PGA970 software.
How to configure LVDT signal conditioner output to DAC so that I will get the output from Vout (TP3) as I vary the probe the output voltage will also vary.
Thanks and Regards,
Kindly give reply on Above message..
Awaiting for your reply,
If you have not already, I recommend following the instructions in the PGA970 GUI User's Guide (http://www.ti.com/lit/ug/sldu023/sldu023.pdf) for configuring the excitation waveform. This is found on page 33.
If you have already done that, can you please send me a scope capture of the waveform output that you are seeing?
