Hi Community

I am struggling a bit with the ADC channels. 

I am using the OS-Less ADC demo. This demo works with thevariable resistor on the SPC560D-Discovery board. My question is why is thisdemo working only with channel 36? I tried several configurations and i getevery time some static ADC values. I mean if i change the resistance the ADCvalue does not change. The exception is Channel 36 this channel works fine. 

I hope somebody can help me.

kind regards

Philipp

Hello Philipp ,

Sorry for the late answer

Yes this demo works only on the channel 36

ADC1_S[4] ==> CH36 ==> 36

Cf Chapter 26.5.1

on the channel 36 , the values are updating.

      Best regards
