IWR6843: How to transfer adc raw data via SPI on IWR6843 ES2.0

HI, there:

Do you know what is your data rate you want to achieve for this ADC raw data transfer?

Hi Zigang

We calculate based on the largest adc data that the radar can transmit. The current problem is that this data path does not seem to work, if SPI is used.

HI, there:

When you say the data path does not seem to work with SPI, what do you mean?  

I do not think we have a demo code that uses SPI for raw data transfer. But we have a API driver code and test code located at: C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\spi\  if you are willing to develop the code for this purpose?

Hello

My mean is the amount of ADC data is too large  so that the SPI may not have enough bandwidth.

HI, there:

Yes, the SPI interface is limited comparing to LVDS interface.  But for debug, maybe you can slow down your chirp (add a lot of idle time) to make SPI works for you.
