I've just run a set of tests after noticing that the pico analog in reading is a lot less stable compared to the original.
I've also done a set of range tests where both devices are given the same fixed ref voltage. The original rock solid. I've tried adding a cap to ground on pico, I've tried other ana pins and multiple picos same results.
I'm not sure what I should expect I'm now considering and external ADC which is a shame.
Any ideas?
