12f675 making me a crazy person

Hi Gary,
try ADCON0 = 0

Joe,

No better.
This is very very strange....

Something is strange.

I just tried your code for giggles and this is what happened.

It is not your code, something else is the matter. A lot of folks seem to be having problems with this chip....

Dave,

That's interesting.....
I tried with various settings in the config, watchdogs on and off, etc. I always use a 4k7 from MCLR to +5. That's just a "standard" here, and I always use the internal osc, and have never strayed far from 4mhz, so suffice to say that the config is pretty "plain".

Most of the timing floats someplace around variations of 1000 so that an aprox count in seconds should tell me when things happen.

The ONLY change here since the last functional chip is 4.31 software on the MELabs Programmer. And it's interesting that there's another thread nearby that the fellow is using the same programmer (although a much older code) and having "odd" issues.

Once again I've shipped it over to MELabs with a request for help.

Thanks to all who have responded. This kind of discussion is enlightening..

Cheers
Gary

Jerson,

The only change I see in your suggestion is an "else" for the Chubb. That part of the code is the only part that works repeatedly....

There is something whacked in the way the counter stuff is getting either compiled or put to the chip, or interpreted by the chip. That part is going off into lala land.

Hi,

Here is the V2.60 Answer :

C:\PROGRAM FILES\MICROCHIP\MPLAB IDE\PROJETS\MERIACHEE.BAS ERROR Line 63: Syntax error.
C:\PROGRAM FILES\MICROCHIP\MPLAB IDE\PROJETS\MERIACHEE.BAS ERROR Line 76: Syntax error.

Translated : Do not use " Loop " but "LoopA" ...

No more error after changing " loop "



Considering your program behaviour ...

The IF THEN sequences looks highly Hazardous to me ...

I'd recommend you to make it somewhat clearer ... but it's me !!!

Gary,

Can you add the following lines to your code and compile it with the PM assembler like this
C:\PBP\PBPW.EXE -apm -p12F675 "C:\MAC\PIC PROGS\TEST\12f675.bas

@ device  INTRC_OSC_NOCLKOUT, WDT_OFF
@ device  MCLR_OFF, PWRT_ON
@ device  CPD_ON, PROTECT_ON

This will embed the configuration into the HEX file. The way you have it now, I have simulated the code and find it is incrementing and repeating after 300. If you want the code to block per trigger of Chubb, you need to add the following to your trigger code

    if Chubb = 0 then
        high trig
        if X < 11 then
            X = 12
            gosub cola
            while Chubb : wend    ' wait while Chubb is 1
        endif
    else
        low trig
    endif

Good luck

Gary

Not so sure ... you caught it !

the "foto1" Label MUST end with a " GOTO " ...

Lala land is the GOSUB result ...

Jerson,

That won't work. The Chubb needs to be high or low irrespective of the Led.

Alain,

P&J, toast and jam, goSUB and return. Can't change one without the other. Code works like a charm. It may not be elegant, but I'm not charging myself very much for it either...

Cheers
Gary
