How to debug in MPLAP IDE?

[ThomasT]

How can I debug my own application using the IDE'S simulation debugger?

Generally:

Is it possible to get the source code of MIOS?

Another question:

In the old software version there were different kind of display modi and cursor button functionality. Have I to program my own behaviour from the scratch or is there a kind of framework, example?

Hi Thomas,

I will publish the source code of MIOS over an official channel (sourceforge.net) when I feel pleasant with the implementation... however, you don't need the source for debugging, and if any function or relation is unclear, please ask here so that I can documentate it. I'm planning to collect all the questions&answers for the programmers guide.

Debugging - the simplest way: add a "org 0x00000" at the end of main.asm and call the function which should be simulated. Following example helps you to simulate a button event:

        org     0x00000

        ;; (Input parameters: see documentation of the USER_DIN_NotifyToggle function)
        movlw   0x00    ;; 0 == button pressed
        movwf   MIOS_PARAMETER2
        movlw   7       ;; button #7
        movwf   MIOS_PARAMETER1
        call    USER_DIN_NotifyToggle
EndlessLoop
        goto    EndlessLoop

        END

Since the Input/Output parameters of the hooks are clearly defined in the functions reference, it shouldn't be a problem to debug in this way.

Framework for menu/cursor buttons: the most enhanced handler can be found in the SID application, the MIOS implementation of the old handler known from the PIC16F based firmware can be found here: http://www.ucapps.de/tmp/mb64seq_snapshot.zip
