PIC12F675- LED on GPIO4
Posted: Tue Sep 30, 2008 3:50 pm
I'm a relative newbie to PIC's and having trouble getting a 12F675 to simply blink a LED on GPIO4. I have Flowcode3 and recently upgraded to the Pro version. My Flowcode simulates fine, but will not run at all after programming the PIC. I use a Melabs U2 programmer and the hex files appear to be loading fine.
I'm using the internal osc (4MHz) and saving the calibration, not using any resets (WDT,POR,BOR, etc.) and my target circuit looks good with a solid 5.06vdc supply, sourcing the LED through a 1K resistor to GND. I have programmed other devices (mainly 16F877's) with more complicated code, so this seems silly.
I'm sure I am missing something simple... anyone?
Thanks in advance.
