Using MCLR pin at Input

[aerostar]

I have this in my program (PBP2.60C) and am using GP3 as an input and it works fine.

@ DEVICE PIC12F683, intrc_osc_noclkout, wdt_on, mclr_off, protect_off , bod_on

INCLUDE "ALLDIGITAL.pbp"

The ALLDIGITAL.pbp just makes sure I have everything set as digital.


The problem is that the PBP assembler uses mclr and mpasm uses MCLRE , see the .inc file

"device pic12F683, intrc_osc_noclkout, wdt_on, mclr_on, protect_off"
"__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF"

I believe to use the MCLRE pin as a digital input these 2 lines must read "mclr_off" and "_MCLRE_OFF"

But ONLY if you always want it OFF - and then have to remember to change it in the program, when you want it on.

The inc file is for general use, and idealy should be left unchanged, - you use the config statements in your program to over ride, as per the statement at top of post 3
