'Define CCP1_BIT 2 'Bit 2

' Variables
Posit var Word
Speed var byte
Pause 100

Scan:
ADCIN 3, Posit ' Read channel AN3 to Posit
Speed = Posit/4
HPWM 1,Speed,1000
Pause 10
Goto Scan
End
OK, I'm still trying to understand this and use code, so I thought that I would revive this thread.

Above, the code has "ANSEL = %00111000 'AN3 analog" To me it looks like AN4 and 5 are also made analog. Is this needed? if it is not needed, I should be able to use:
Code:
ANSEL = %00001000  ' AN3 analog
