There's a R-M-W (Read-Modify-Write) problem when OUTPUTting to a pin set to Analog. It adds a high frequency component to the PWM signal.
Would the following be correct
Code:
TRISIO.2 = 0 'Set GPIO.2 to output.
ANSEL.2 = 0 'Set GPIO.2 to digital
GPIO.0 = 1 'gpio.0 set to input
VRCON = 0 ' Voltage reference disabled
OPTION_REG.7 = 0

I'll try that and see what happens, thanks for the suggestion
