PCM Programmer

I'm not religious by nature but God bless you for writing this. It saves me untold time and aggravation. It works fine on my old (red) 2002 PICDEM 2 PLUS board.

Right you are. I had a ROM statement where I had inserted a version string in eeprom on a 16F processor.

I noticed that the DAW location was always 210C no matter when everything else changed in t ...

I am able to to make this problem go away at times but one thing that stays consistent is that program location 210C is always a DAW command. The assembly code around it can change as I add more C co ...

I tried calling the rpc routine before the serial routine and it seems to be working ok now and the dissassembly looks more like you'd expect.

I tried inserting some junk code before the switch but the DAW is still there and the switch does not execute the proper case.

358: void rpc_exec(){
359: ...

I tried replacing the switch with multiple IF statements and came up with the same DAW as shown in the earlier code. RPC is an in8 global.
Thanks.

Here is the main() code that calls the rpc_exec ...

I'm back to this switch problem going to the wrong case. I'm looking at the disassembly listing and see something wrong at the top. Case 5 is not shown and there seems to be an inordinately large gap ...

OK I figured it out.

It should be: cc=*string_start++;

Thanks.

I'm not sure this is related to my other problem I've been posting about
but I'm having a problem using a pointer. I was wondering if somebody could look at this code and see what might be wrong wi ...

Yesterday I removed all routines that had not yet been filled with code. This 'fixed' the switch problem. Now I'm seeing something I saw the other day. I have a routine calling another routine, it ...

Setting up unique code for each Case didn't help. The fact that I can call it from Main() or remove executed code ahead of this routine seems to rule out all kinds of things.

Thanks for the reply. I tried all kinds of things including putting code in Case 1, removing the default case, break up the 30 switch cases into 3 seperate switch statements.

The two things I did t ...

Thanks for the reply.

The code executes case 1.

I suppose I could remove the default case. I just did that "in case" - no pun intended.

My feeling was maybe that maybe there was so ...

OK I'm having the same kind of problem but in another switch statement.

MPLAB version is 8.3.0.0 CCS compiler version is PCH 3.249

In the routine below, I break at the top of the switch and r ...

Geez are you kidding ?

The reason I'm not going further with this is because I'm in a hurry to do other things and this may not turn out to be a problem anyway. So why waste everybody's time ? I'd ...
