I am trying to use this simple servo code on a 16F684 using portc.1. What am I missing? Why doesn't it work? All that happens is the servo twitches when downloading the hex file, then that's all.
OSCCON = %01100001 '4 Mhz on internal osc
TRISC = %00000000
PORTC = %00000000
x var byte
y var byte
main:
for x = 0 to 50
pulsout portc.1, 75
pause 20
next x
pause 2000
for y = 0 to 50
pulsout portc.1, 175
pause 20
next y
pause 2000
goto main
end
Hi,
The answer is in your Datasheet ...
PortC1 is shared with the on chip ADC ... so you must tell the chip you want to use it as a DIGITAL pin ...
BTW ... Comparator also shares this pin ... soooo ...
Two datasheet sections to review ...

Thanks! That helps a lot. I use a lot of different PIC chips
and it's been a long while since I used a 684. I thought I
had remembered all the details.
:)
