Instant Interrupts - Revisited

[mister_e]

Yup it's working really well indeed. Interesting how it could be handled as ASM... Being said, it open a wide range of USB testpoints as well.

Oh... when i compiled your example i got an error message... Config fuses related... in this line

    __CONFIG    _CONFIG1H, _FOSC_XTPLL_XT_1H & _FCMEM_OFF_1H . . . . . .

Must be _FCMEN_OFF_1H

Thank you very much Darrel for your time on this one!

Now, i have to read the USB18.ASM file to understand WHY it's working like that now, AND to see what else we can do with

Must be _FCMEN_OFF_1H

Interesting, I got the same error with your's. Except I had to change it to _FC_MEM

After further review I see the P18F4550.inc file in my "MPASM Suite" folder shows these configs for CONFIG1H

Is yours different?

If you want more info on the ASM handling of the USB_INT, I can elaborate some.

Just checked mine for grins...
I've got FCMEM in my 4550.INC file

Also checked the file straight from the .zip file from Microchip, it's the same.

[mister_e]

Yup! seems mine is different... looking on another forum thread (12 Bytes code one ) i know we don't have the same MPLAB version... 7.50 Here, MPASM 5.06

Here's a .inc file quote]

_FOSC_HS_1H          EQU  H'FC'    ; HS oscillator, HS used by USB
_FOSC_HSPLL_HS_1H    EQU  H'FE'    ; HS oscillator, PLL enabled, HS used by USB

_FCMEN_OFF_1H        EQU  H'BF'    ; Fail-Safe Clock Monitor disabled
_FCMEN_ON_1H         EQU  H'FF'    ; Fail-Safe Clock Monitor enabled

_IESO_OFF_1H         EQU  H'7F'    ; Oscillator Switchover mode disabled
_IESO_ON_1H          EQU  H'FF'    ; Oscillator Switchover mode enabled

and above... with the new CONFIG plah plah...

;   Fail-Safe Clock Monitor Enable bit:
;     FCMEN = OFF          Fail-Safe Clock Monitor disabled
;     FCMEN = ON           Fail-Safe Clock Monitor enabled

Anyways.. it's no surprise at all that Microchip change it from a version to another

If you want more info on the ASM handling of the USB_INT, I can elaborate some.

EDIT: i'll download the new MPLAB version and see what's different or Still the same... interesting...

EDIT #2 : Just remove and re-install V7.50 (No i never download a interim version) and FCMEN is still good. Maybe they discover that Fail safe Clock Monitor Emable make no sense? Same as mixing Moon and Mood :-]

[Darrel Taylor]

Hmm, I think we have a Spock moment here... "Fascinating!".

OK, 3AM here, sleep first. ASM Interrupts tomorrow.

Looks like it's time for an upgrade on my end. Arrrrgh!
But here, let me shoot the moon first.

Whew!, You're lucky that didn't go through.
