I work with a MKE18F512 and I have to use the ADC.
We work with 5V Supply and a external 5V Ref
Now I have the problem that the any ADC pin is at 2,5V and delivers up to 20µA out current.
Could this be correct?
Why are the ADC pin at 2,5 in idle position.
To test this problem I have disconnect all connections form the ADC pin but it stays at 2,5V if the ADC run.
I am happy about any idea.
