pic Basic Pro 2.50a & debug statement

[Phil Moore]

Code below for 16F737 compiles & runs just fine under PBP 2.46. Compile under 2.50a and everything runs OK *EXCEPT* DEBUG (nothing changes on debug pin).

Running MicroCode Studio v3.0.0.5 & WinPIC v??? (compiled Jun 3 2007). Using MPLAB 7.60.00.00 and MPASM (not PM).


Am I going nuts or is something broken?

' Code:
' System Constants
OSCCON = $F0 ' Tell the PIC
ADCON1 = 7
CMCON = 7

' Defines
DEFINE OSC 8 ' Tell PicBASIC
define DEBUG_REG PORTA
define DEBUG_Bit 1
DEFINE DEBUG_BAUD 9600
DEFINE DEBUG_MODE 1
define PULSIN_MAX 1000

// snip //

' Code start
init:
pause 100 ' let things settle
debug "Start",10,13

Any ideas greatly appreciated.
Phil.

Config fuses set the same between the 2 PBP versions?
Did you change something in the .inc file way back when and forget about it?

MPLAB 7.60. There is a newer version...not that it'll help anything...you never know...

Hi Skimask,

I did change over from PM to MPASM as I was doing other stuff with 18F chips, however, the only config change I made to the 16F737.INC file was to set clock to INTRC with IO. This is the same config I had with PM:

' Device fuses & registers (Assumes PM assembler)
@ DEVICE INTRC_OSC,MCLR_ON,WDT_OFF


Fuses:
Osc - INTRC as IO
WDT - Off
PUT - Off
RE3/MCLR = MCLR
BODEN - Enabled
BODENV - 2.0V
Backbug - disabled
CCP2MUX - RC1
CP - Off
BORSEN - enabled
IESO - enabled
FCMEN - enabled

Device (DVD simulator - don't ask why) is powered off USB port of PC, with extra cap for filtering - don't think it's a voltage thing.

Cheers
Phil.

I don't see anything turning off the ANALOG function of PortA.1 and switching it over to digital...

Actually, yes I do see something turning off SOME analog ports, but not enough...

Hi Skimask,

Changed ADCON1 to $f, but no joy (if that's what you meant).

Yep, you got it.
Try a different pin without any analog functions on it, just a plain ol' pin.
Try one of the SEROUT commands and see what happens.
Try a bunch of things...try anything.
