PIO is fantastic. Revolutionary. Not trivial to use but extremely powerful and adaptable. Too bad about the ADC. To be clear: the ADC is not "OK". It' s BAD.

- GeorgeTirebiter 2y agoUnfortunately, the poor ADC performance is due to a design / simulation error; at least you have to give them credit that they 'came clean' on the crappy performance, and explained it in the official documentation: https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.p... section 4.9 See https://pico-adc.markomo.me/ https://pico-adc.markomo.me/ for a thorough analysis of the problems. Especially look at the DNL.
