Greetings all,
Im having a problem getting any code Ive written to work on a 12F675. Im using PicBasic Pro to compile in the MPLABS IDE. Im also programming threw the USB PicKit 1.

The kit came with a few tutorials that I can get to work(used to verify that the internal clock was indeed running) but I cant get anything I write and compile into HEX to do anything. Ive tried simple:

loop:
High 1
Pause 1000
Low 1
Pause 1000
Goto loop
or
loop:
GPIO.1 = 1
Pause 1000
GPIO.1 = 0
Pause 1000
Goto loop
and a few other simple variants and cant get an led to light. My leds polarity is correct, also the tutorial programs do alot of things with 8 leds on the evaluation board that all work properly.

Ive configured the compiler and MPLAB as stated on their site so Im guessing that I dont have something inside the IDE right. Ive picked the proper chip, and programmer from the MPLABs drop downlists.

Any help or advice will be greatly appreciated.

<EDITED>
I changed gpio's to pin 1, previously I used 3 as an example but pin 3 is a dedicated input so might cause some confusion

 

kk found part of my problem.

I can get correct output on pins now with the Low and High command (low 1) but why doesnt the GPIO.1 = 1 work? It isnt a huge problem that I cant work around but from what Ive read it should work on my PIC.

 

You need to set the ports TRIS to configure the pins as outputs.
