PGA970: help with source code

Mohammad Hafeel B

Part Number: PGA970

hello,

i a working with the pga970evm board, and i got the source code . but i am new to thease codings and i am unable to process it to further. i want to generate the 4khz sine wave and i don't know how to do it.

i gone through the datasheet (page no 58) and i am not understanding the procedure . because i don't know how to implement this procedure in my source code.

can any one tell me how to generate 4khz sine wave from the source code and what and all changes i have to make to source code. give me the working main.c file

Thank you.

Hi Mohammad,

Unfortunately, I don't think I will be much help given our support model for the PGA970:

[FAQ] What is the E2E support model for the PGA900 and PGA970?

That being said, I really recommend you use the PGA970 GUI to help you. Navigate to the ADC Settings page, look at the waveform generation section and then populate the waveform table. These are the values and settings you'll need to create a waveform of your choosing.

Then, you transfer these settings into your project and assign them to the appropriate spot in memory. That's the high level idea. There is a whole section in the user guide as well: https://www.ti.com/lit/ug/sldu023/sldu023.pdf

Best,

-Cole
