Hello,
Basically I am driving coils of the stepper motor and changing the pulse width (DLYCADC) and hence frequency.
I feel ADC is not measuring the counts (or no acquisition) and hence I do not see anything at ADRESH or for change in voltage at AN7 has no effect. let me clarify here that I do...
Help on ASM code - 16f676 ADC not working
I am using 16F676 to change stepper motor rpm
Problem ADC is not working viz. for AN7 = 0 or +5V, no change
Analogue input 0 to 5 V potentiometer, at AN7 (pin 7)
Reference is VDD +5V
Conversion selction 16Tosc
Output at pin <11:8>
Check the problem...
