SDK • Re: RP2040 ADC sampling speed

The pacing timer is "(16 integer bits, 8 fractional bits) for setting free-running sample rate", that give minimum around 730 Hz. Try to reduce ADC clock with SDK:

4.1.4.7.3. clock_configure

Thank you a lot, It makes sense now (using e.g. 8kHz works fine). Indeed for slow paced sampling I'll use a timer alarm which should do the job
