Hi guys,
I have a strange problem with 16F1828 .
So, I want to use AN6 (PORTC.2) to read a variable from 5k potentiometer . In main program if I use only HPWM2 , all works ok.
If I add HPWM1 , on AN6 pin I have not a proportional voltage, like this pin is not analog input.

Can somebody help me, please ? The last 2 days I spent my time to solve this problem, but no succes !


Code:
#CONFIG
        __CONFIG _CONFIG1, _FCMEN_OFF & _FOSC_INTOSC & _WDTE_OFF & _MCLRE_OFF & _CP_ON & _IESO_OFF & _BOREN_OFF & _PWRTE_OFF
        __CONFIG _CONFIG2, _PLLEN_OFF & _STVREN_OFF & _LVP_OFF
#ENDCONFIG
