Huh? MPASM? (pause for thought) - Oh yes, that's the windoze based thing. If
I had stopped to read what they wrote, I'd still be reading and never have
written any software at all yet :-o.
As things stand, I have the project software drafted, and am debugging. It is
a strange feeling to have a linux programmer suggest reading windoze
documents :-). Thanks for the idea though; I'd never have thought of it :))).
I did boot up M$ windoze, installed MPASM and took one look at that with my
sons here one day. We all agreed that whatever we were going to use, it
wasn't MPLAB.
grep found this and similar references; This one is in
~/mplab/template/Code/f877temp.asm
__CONFIG _CP_OFF & _WDT_ON & _BODEN_ON & _PWRTE_ON & _RC_OSC & \
_WRT_ENABLE_ON & _LVP_ON & _DEBUG_OFF & _CPD_OFF
; '__CONFIG' directive is used to embed configuration data within .asm file.
; The lables following the directive are located in the respective .inc file.
; See respective data sheet for additional information on configuration word.
(Boots windoze and comes back)
So I can set the configuration word, ID blocks and all with this __config
statement? That's what the mpasm help says. If I set the configuration word,
will I have to change to int32 hex format also like they appear to say? The
16f7877 only has a 16 bit configuration word.
