| How to debug PCM compiled code in MPLAB with ICD2 |

Hi all,
I'm a CCS newbie. I've tried to debug a c-project (multiple c-files) in MPLAB 8.0 with ICD2. But i can only step inside the disassembler window. Not inside the C-source window. I would like to do debugging in the c-code. Is it possible ? Any hints on how-to ? Which Debug-File format ?
Thx.
Many Regards, Thomas |

I tested this just now with MPLAB vs. 8.01 and PCM vs. 4.066. It worked
fine.
1. Install the MPLAB, the CCS compiler, and the CCS plug-in.
2. Create a new project in MPLAB, using the Project Wizard.
3. Connect the ICD2 between your PC and your test board.
4. In MPLAB, in the Debugger menu, goto Select Tool, and choose ICD2.
5. Then compile your program.
6. Go to the Debugger menu, and select Connect. It may announce
that it's downloading a new "operating system" to the ICD2. Wait
for it to finish.
7. In the Debugger menu, select Program. Wait for the ICD2 to finish
programming the PIC.
8. Let's assume you have the following program as your project.
You should have this program visible in the source window.
| Code: | #include <16F877.H>
#fuses XT, NOWDT, PUT, BROWNOUT, NOLVP
#use delay(clock=4000000)
//=========================
void main()
{
int8 c;
c = 1;
c = 2;
c = 3;
c = 4;
while(1);
} |
Go to the line for "c = 1;", and double-click in the margin to the left
of that line. A red circle with a "B" should appear. If you get a hollow
circle without the B, then it means you didn't do one of the steps above,
such as programming the PIC from with the Debugger menu.
9. Now press the F9 key. The program should run to the line with the
breakpoint on it and stop. A little green arrow in the margin should be
pointing to that line.
10. Now press the F8 key, slowly, once per second. After each press,
the little green arrow should advance to the next line. This is all taking
place in the source code window. All this time, you will be looking at the
program posted above.
It works fine for me. |

Thanks PCM.
This describes is how i've done/tried it. But this doesn't work if your source consists of many c-files (like main.c adc.c i2c.c timer.c blabla.c). Then only the first linked file will be opened and you'll step always in this c-file even when the source is in another file. In other words: multi c-source debugging doesn't work in MPLAB8.0 w/ CCS-Compiler.
Any hints ?
thx. |

| Multiple source files |

I can't remember why I did it this way, but on some projects I made one *.c file that had my 'main()', and several separate files with related groups of functions/procedures. I named them as *.h files, added them under header file section of the project , and that worked for me. You might give that a try.
Cheers

| I never had problems debugging multiple C-files in my projects. What is the version number of your CCS compiler? |

Hello,
I tried the test program except I replaced the <16f877> with <18f2525> and after I program the chip and hit connect I get this:
Programming Target...
...Validating configuration fields
...Erasing Part
...Programming Program Memory (0x0 - 0x3F)
...Loading DebugExecutive

MPLAB ICD 2 Ready
I have always used the ICD2 hockey puck as a programmer and haven't tried it as a debugger. It is connected to the PIC via a 5 pin connector where the pins are PIN1 to GND, PIN2 to Vcc (5V), PIN3 to MCLR (which has a 10K pullup tp 5V), PIN4 to PGMD and PIN5 to PGMC. |

Hi,
It worked...after I unplugged the hockey puck from the computer a few times. Thanks. |
