A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

Has anyone ever seen this? I'm using mplab 6.30 and the mplab simulator. I have a number of memory locations in the watch fine and they aren't getting updated. I can step over a movwf foo and w will have some value but foo only shows 0. Looking at the file registers shows the location of foo shows 0 also but when I step over movfw foo, w gets the correct value even though foo still shows 0. I tried restarting mplab, rebuilding the project, deleting the watch item and re-adding it. nothing seems to work. this is sure making the simulator useless. Phil

I have tried this with mplab version 6.62 and can not confirm this happens in this version. The only way this appears to happen if I wipe memory with debugger,clear memory,all memory after which the program still appears to be there (the cursor still points to instructions in the assembler text window) but the program memory is wiped and only contains addlw 0xff instructions. I did not try version 6.30. Peter --- Phil <> wrote: > Has anyone ever seen this? I'm using mplab 6.30 and > the mplab > simulator.

Yeah, I've seen something like this. It happened because I was in the 'wrong' memory page, so the 'W' register read a 'foo' that I wasn't watching. Could that be happening here? --- In , "Phil" <phil1960us@y...> wrote: > Has anyone ever seen this? I'm using mplab 6.30 and the mplab > simulator.
