Is there any way to measure up to 20kHz frequency, two chanel, on panda 2 ?
If ram is the problem I could simulate it with sd memory card. Also it would be nice if there wouldn’t be to much latency…
Why do you need fft? See the very previous post about pincapture function please.
Most likely you won’t be able to perform real time FFT in managed code. You shall use RLP for that. However the FEZ might not be the best platform for signal processing…
