Post by thread:MPLAB help - stimulation with delay loops

When running MPLAB stimulator in single step fashion to try to debug an LCD control program, I ran into some 10msec delay loops - OUCH! What takes a short time when the PIC is running, takes many hundreds of mouse clicks or more to step through the program. Even the "Animate" mode was taking way too long to get through these delay loops. What is the easiest way to deal with this? I haven't figured out how to use breakpoints yet but would a breakpoint at the end of the delay loop stop the program here so I can resume the single step stimulation? I don't want to comment out the delay loops as I am not sure the program will run properly then. Thanks. Charlie WA2IPZ Burley, Idaho

I just comment out (or jump around) the delay loop during the simulation phase. ----- Original Message ----- From: "Charles L.

OR.............manually change the values that determine how long the loop is taking, in the memory of the simulator to speed things up.

(:^) put the loop values on a EQU in the start of the program. Change it to a low value when simulating, return it to the correct high value when burning. As I'm using CCS, I change the line "#USE DELAY(clock=20000000)" to "#USE DELAY(clock=1000)" when simulating/debugging.

If the delay loop is a separate subroutine, you can use F8 to run the subroutine at full speed, then stop when it returns.

I had exactly the same problem with a LCD routine too. If your delay is a subroutine, add a label such as "DELAY_TRAP" on (or just before) your RETURN instruction. Then from the BREAK SETTINGS menu option, select DELAY_TRAP (from the pull down label list) as your break point. The break point will then have a tick next to it if it is enabled. Whenever you reach the delay loop during single step, just press F9 to run through the delay. Regards Tony

Is it something you can use step over on? Otherwise you can comment out the delay or modify the program counter to jump past the loop. You can also modify the counter register to shorten the loop while stepping thru.
