I'm using a version 3 Dev board, and starting thru the C$PIC course.

Trying to run exercise 1.1, but cannot build the program as I get errors from interrupt.c:

Code: Select all

Exit code was 1.
Removing target: interrupt.obj
Done

I did some searching within the foum, but could not decipher the fix a it was described. Can't find anything in any of the documentation to help me understand this one. I'm using the 1688 supplied with the board.

Any help to get me moving in the right direction is appreciated.

Hello

My exercise 1.1 looks like this

Code: Select all

/*  EX1.1 Light a LED      */
/*  David Miles April 2006 */

#include <system.h>

/* Set 8 MHz clock frequency */
#pragma CLOCK_FREQ 8000000

/* Set PIC16 configuration word */
#pragma DATA _CONFIG1, _EXTRC_CLKOUT & _WDT_OFF & _LVP_OFF

void main()
{
	trisa = 0xfe; /* set bit 0 of PORTA for output     */
	porta = 0x01; /* set bit 0 of PORTA to 1           */
}

Is this the same as yours? Interrupt.c should not be getting called by anything in the code. Have you included it somewhere in the IDE environment?

Whenever I open Sourceboost via the C4PIC icon, that is what opens up. That appears to be the issue. I'll see what I can do to close it, or prevent it opening.

I should get a clean IDE with nothing opened when I first open Sourceboost, right?

I see what I am doing wrong.

I was clicking on the SourceBoost icon, rather than the link for the exercise under the vpic.
