I am trying to experiment with changing the sampling frequency in the profileCfg command. To achieve the goal of my project, I need to have a profile with a short chirp period but still have 256 ADC samples. According to the mmWaveLink doxygen, the highest sampling frequency for the ADC is 37.5 MHz which means I should be able to reduce the chirp period to ~6.82 microseconds and still be able to collect 256 ADC samples. However, in my configuration, I am trying to have a period of 13.25 microseconds which means I should have a sampling frequency greater than 19.32 MHz. I chose to use 20 MHz, but the mmWave demo threw an error after I tried to upload my profile. Here is the command I am trying to configure:
profileCfg 0 77 3 3 16.25 0 0 8 1 256 20000 0 0 30
Why does this throw an error and what can I do to fix it?
