12f675 code will compile but it would not run
PostPosted: Wed Dec 29, 2010 12:44 pm     Reply with quote
I have this simple code that I been trying to run on my pic12f675

Code:
#include <12F675.h>
#fuses INTRC_IO,NOWDT,NOPUT,NOPROTECT,NOMCLR

#use delay(clock=4000000)


void main()
{
   while(1)
   {
         OUTPUT_HIGH(PIN_A0);
         delay_ms(1000);
         output_low(PIN_A0);
         delay_ms(1000);
   }
}


it does compile but when I burn it into the chip it would not run I though it was something wrong with the hardware, but when I put this hex file that I downloaded from online the led starts blinking

What's your compiler version ?

Are you running this in Proteus or a real board ?

Also, what's the Vdd voltage on your PIC board ?

I installed vs. 4.068 and it works in hardware. The LED is blinking.

I don't see an LED on your schematic. My LED circuit looks like this:
Code:

pin      470 ohms      LED       
A0    ---/\/\/\/------->|----
                            |
                            |
                          -----  Ground 
                           ---
                            -

Also, make sure you compile the program for "Release" mode
and not Debug mode.
