breakpoints within interrupts

Hi All, Not sure anyone has ever required to set break points within interrupts, but this seems to be a serious limitation of the MPLAB v6.13 + Hi Tech PICC combination. I'm using MPLAB v6.13 along with Hi-Tech PICC compiler v8.01 PL3. I'm unable to set breakpoints within the interrupt function in the C code, whereas I can set the breakpoints in any other function including main. When I was using MPLAB v5.62, with the same compiler, I did not have such problems and I could set breakpoints even within the interrupt functions. I'm desperately in need to set breakpoints within the interrupts to debug a program and I want to do it using MPLAB v6.13. Any suggestions or help in this regard would be greatly appreciated. The same problem persists with MPLAB v6.10 Best Regards, Naveen.P.N. |

I've gotten around it in two different ways: 1) Pull your interrupt handler code out of the interrupt handler proper and put it in a subroutine that the interrupt handler calls. You should be able to set a breakpoint in this subroutine. 2) Put a breakpoint at address 04x (i.e., the address of the interrupt handler vector) in the "program memory" window. For some reason, I can't set the breakpoint in this window by double-clicking. I have to right click and select 'set breakpoint'. Good luck. |
