Hello,

Compiling it, gives me some Warnings "Found Directive in column 1.(_CONFIG), but it compile. At the oshon simulator, the same result, the pins of the microcontroller doesn't change at all...

Thanks,
Nuno

I do not use simulators, I can not help you there.

For the warning, SPACE the
__CONFIG
over by one.

[nuno106]

Yes, the warning disapears... Thanks

I'll try to program the chip and test it.

Thanks,
Nuno

Hello,

I've tested with the Pic, but without luck, nothing happens...

Are this configurations correct?

Thanks,
Nuno

The default location for PBP is
c:\pbp

But if it is compiling where it is...
How did PBP get installed inside of MCS?

[nuno106]

Hello mackrackit,

I don't know how pbp intalled there... i've intalled it a long time ago.

I'm looking at the assembler code, and it loops at:

CLRWDT --> Clear WTD
BTFSS PIR1,RCIF,A --> Check if Receiving bits... but i don't have nothing in my code...
BRA-3 --> Goto the CLRWDT again

anyone understand it??

Thanks,
Nuno
