I believe my identification of the problem in the Pico slightly preceded Markomo’s comprehensive analysis. Target audience: MicroPython users with an RP2040 boards. Characterizing the Raspberry Pi Pico ADC. The conversion time of the ADC is the time it takes for the analog signal to be converted to become a digital signal, in devices like the ADC24, TC-08, PT-104 and so on is not very fast (as they do not need to be). Because FFT outputs are complex-valued, you may use the magnitude of the complex result to get a useful power value. The DMA module may be set up to automatically grab samples from the ADC as soon as they are ready. The following code was used to sample the ADC at it's full rate then dump the samples out the USB serial interface: You can increase clock divisions to sample at a slower rate.
