Hi guys, I'm totally new to MCUs and the Beagleboard and I'm a little overwhelmed by the amount of information out there. For a class project, I need to sample a signal (the beat signal out of a FMCW radar module, the frequency is not higher that audio), detect its frequency, and use this frequency value to calculate the range and/ or speed of my target.
I'm pretty sure that I can use either the beagleboard-xm or the beaglebone black for this, but I'm confused about a couple things. I hope that I can get help here! Can I just use the CPU on the BB-xM or the BBB to sample the audio and do the necessary processing or would I have to use the xM's DSP or an audio cape for the BBB? I have written simple DSP applications in C before, and so far I have used JACK to get my samples from the sound card. Could I do the same thing on the Beagleboard? Would grabbing samples for computations in a C program also work by using ALSA? In order to detect the frequency of my signal, I believe that I will have to take chunks of the signal, take the FFT and detect the peak in the resulting array. Can I do these operations on a beagleboard without significant delay? Thanks for your help!
