pic Basic Pro 2.50a & debug statement

[Bruce]

Change DEFINE DEBUG_Bit 1 to DEFINE DEBUG_BIT 1 and it should work.

Having the last 2 characters in lower case was making pin RA0 an output VS RA1.

At least is was in MPSIM. I don't have a 737 to test, but this works fine in MPSIM once
I change Bit to BIT.

  @ __config _CONFIG1, _INTRC_IO & _MCLR_OFF & _DEBUG_OFF & _WDT_OFF & _CP_OFF


' Defines
DEFINE OSC 8
DEFINE DEBUG_REG PORTA
DEFINE DEBUG_BIT 1    ' note it's all UPPER CASE
DEFINE DEBUG_BAUD 9600
DEFINE DEBUG_MODE 1   ' 1 = inverted

    ' System Constants
    OSCCON = $F0  ' set 8MHz internal
    ADCON1 = $0F  ' all digital
    CMCON = 7     ' comparators disabled

' Code start
Init:
    PAUSE 100 ' let things settle
    DEBUG "Start",10,13
    GOTO Init
    
    END

There's a section in the library that sets up default values, and if something isn't
DEFINED, the value will be whatever the default is. In this case it's 0.

ifndef DEBUG_BIT ; Debug pin bit
DEBUG_BIT EQU 0

If wasn't seeing DEBUG_Bit as DEBUG_BIT so the default was RA0.
