AWR1243: 1D/2D FFT source code, Doppler bins

J G1

Part Number: AWR1243

Hi,

1.According to the manual, 1D/2D FFT is made on EVE core. Can I see the source code(MIMO & TxBF)? I didn't find them in the SDK.

2.There was an error when I changed the doppler model from 64 to 128 (MIMO mode) :

The explanation I saw in another post:

But this error still exists after I changed the frame cycle from 100ms to 200ms.

And if I increase the number of samples from 256 to 512, I get the same error.

This is the configuration I'm using now:

Which parameter should I change to eliminate this error?

The EVE code is at C:\PROCESSOR_SDK_VISION_03_08_00_00\ti_components\algorithms\eve_sw_01_20_01_00\apps\fft\algo

The frame time is determined by framePeriodicity. Please look at the calculation for framePeriodicity in the code and check if your changes are getting reflected in this parameter.

Thanks and Regards
