18F452 compile error

[Woodzy]

I will try that yeh.
dont why its rejecting the TRISB TRISC etc
Am using the MPASM that came with PBP 2.45, mate.

cheers

euh... as far as i remind, MPASM don't comes with PBP 2.45 (or i miss something in the past)

Download the latest version from Microchip Website.

MPASM = my mistake.
I just use the assembler supplied with PBPro 2.45

cheers

Mister-E,

Took your advice, here is the test program i tried;

------
'e:\plc\pbp245\PBPW.exe -p18f452 e:\2005\FZ4\452LED.bas

ALED var portb.0
high ALED
pause 1000
low ALED
end
------

and now the associated compilationerror messages.
-------------------

You dont think there may be errors in the .ASM or .LIB files listed above??
I was of the assumption that both the 16F877and the 18F452 were both 14bit devices.

any help from any one would be greatly appreciated.

cheers

Woodzy,
You have to use MPASM for the PIC18-series chips. Not the PM assembler (PBP standard). If you're using MicroCodeStudio goto View/Compile and Program Options, select the Assembler tab and make sure that the box use MPASM is ticked. If you don't have MPLAB/MPASM installed you can download it from Microchips site.

If you're not using MicroCodeStudio you need to figure out how to invoke MPASM instead of PM.

Or plug PBP in MPLAB... but i prefer MicroCode Studio
