How to configure more than 1 differential input channels for r_sdadc?
with the bellow configuration, I can only read channel 0 but not channel 1
I could read channel 1 if I deleted channel 0.
It was my mistake. After re-adjust the gain, the of the input is updating conversion data.
There are couple things about this SDADC
1. the manual show if external VREF is used, only 2.4V can be selected…
