Hello,
1)in case of wrong parameter the console returns a -1. The docu describes errror codes in the SW but how can the error codes be read?
Customer found:
System_printf ("Error: mmWave Control Configuration failed [Error code %d]\n", errCode);
But where is the output of the system printf?
2) How can the parameter RAMP_END be interpreted? A RAMP_END time of 40uS sound not realistic that means FMCW of 500m but it is ineffective at 10m. So the demo SW seems not useful for the customer.
3) Customer tries 1x tx and 4x rx and would like to shift the multiply of FFT to eliminate all objects with the multiplication outside of a dedicated angle window. Unfortunately the IWR1443 has no programmable phase shifter but only a binary modulator so that customer can't do active beam forming. He has to do mathematical tricks and different antennas.
4) Customer has problems to get access to the FFTs of the rx in the current firmware. He needs a function with 1x tx and 4x rx which can be shown overlayed (see attachment, the multiplied curve is only drawn for better overview.).
