Pbp + Mplab + Icd2

I didnt get to test the debugger mode of ICD2 using your recommendation coz my proto board was not working well maybe need to recheck the connections.

But anyway...I just observed the format on how the 876 & 877 series ICDDEFS code vs the Program/data memory used was coded..see below.

Any thought about this why? I understand the "reserving 12 bytes of RAM from 0x1F4-0x1FF" on the PIC18F2550 series" but this one seems different.
Am I correct that it is 11bytes of ram was reserved? Why it is written "ICDRESERVED1 & ICDRESERVED11".

Just some curiosity Bruce hope you can answer my questions in here still.

Thanks in Advance

Chris

Hi Chris,

Check with meLabs on this one. Like I mentioned before, I have an ICD2, but I haven't
used it in several years.

I find it a lot less trouble & work to just build the circuit & test it directly rather than use
some in-circuit debug hardware that eats up my time/resources.

I'm not saying in-circuit debug is a bad thing - it's just that I've never been able to justify
the additional time, effort, or cost requirements VS simply testing my code on the physical
hardware in real-time operation, on the target hardware.

I have just never had a reason to step line-by-line through any code that I already know
what it's supposed to be doing. I think it's great for learning, but it's just not something I
need for what I do here.

I will run some sections of code through MPSIM just to find precise timing for some routines
or functions, but I just don't need ICD, so I don't use it, and can't offer much help...;o}

Thanks Bruce....

I got your point & with the idea you presented seems was logical enough coz right now I find it easy to plug the chip into the demo board to debug the program.
Your insight just supported my thought on ICD debugging.

Chris
