Hi TJF, I am getting the hang of the pocket beagle, C++ and libpruio and I am testing some features. Thanks again for your efforts because it has been really helpful. One of the things that struck me as odd is that the claim of the beaglebone is 12-bit ADC's. What I see when I measure the analoge pins is values that differ by 64. This suggests that the pocket beagle is not 12 bit but 10 bit... (full range is 65536 and differences between values are 64 is 1024 steps or 10 bits). I must say that the difference is not 64 consequently but sometimes the differences are 32 bit (other measurement). So it seems the board shifts between bit depths. I tried with sample frequencies 22.1kHz and 1kHz. 1 khz seems inclined to 11 bit.
My question is whether you know if this is because of libpruio or a general issue with the pocket beagle and whether there is a way to fixate the bit depth at 12 also for high frequencies? I measure 8 channels and the number of samples is 220500 (10 seconds of audio at 22.1 kHz). Thanks in advance.
