Nice.. I just want to use the ADC as feedback sensor for a plunger... I all
works fine until the FIFO is full 😉

IFO is full... Maybe I have to add an IOCT

If I understand well, you want to put the ADC to continuously sample an input
at some sampling rate.The ADC ring buffer depth will be set to 1 and should
store the value of the last
If I understand well, you want to put the ADC to continuously sample an
input at some sampling rate.The ADC ring buffer depth will be set to 1 and
should store the value of the last sample. Is that correct?
If yes I think that is not possible because adc_receive() will refuse new
data if FIFO is f
Is it possible to achieve a continuous ADC conversion, where the
sample[0].am_data is written in a struct (and constantly updated) and where I
can get and check the voltage from the ADC?
I have it working that the value I get is true and it also seems to measure the
change, but after some time
