12f683 help

[hcker2000]

Hey I am just trying to do some simple led flashing on the 12f683 but for some reason gpio.1 is not turning on. Here is my code.

Right now the leds on gpio.0 and .1 should come on and .0 does but .1 doesn't light up.

Code: Select all

program LED_Flicker

main:
TRISIO = 0 'Set all pins to output
ANSEL = 0 'Turn off analog stuff
ADCON0 = 0
gpio.0 = 1
gpio.1 = 1
gpio.2 = 0
while true
'code goes here
wend
end.

Try adding CMCON0 = 7 to turn off the comparitors.

Hi everyone

I am having some trouble understanding why this code doe NOT work on EasyPIC5


program Leds_on_683_with_push_button


main:
osccon = %01110111 'set osc to internal 8mhz
CMCON0 = 7 ' turn off comparitors
ansel = 0 ' make i/o digital

Trisio = %101001 'set up input and output
IF GPIO.0 = 1 then ' check if GPIO.5 = 1
GPIO.1 = 1 'If so then turn on output pins
GPIO.2 = 1
GPIO.4 = 1
'GPIO.0 = 1
else GPIO = 0 'if not then output pins are off
end if ' do it all over again
goto main


end.

Hi dandav1,

The code that you've sent works on EasyPIC5 with 12F683.
I've tried it myself. Did you turn on the LEDs and turn off any unnecessary switches off?

Upload the HEX in the zip file attached and see if you still have a problem.
If you do, I would kindly ask of you to take a picture of your configuration and upload it here.


Best regards,
Aleksa.
