16f877a

[dirkwerk]

Hi,
I use microchip MPLab ICD 2 and the picfem 2 plus board, now im complete new to this
so i tried to program in picbasi waht moer familiar looks to me, i set the pbpw as compiler
now when i use a bas program , and compile the message always is:
ERROR: Unable to find -p<pic> processor file
doe any knows whats wrong? i looked on the web for 16F877A.BAS file
buth did not found it. Im getting nervous of this
Thanks any way
Here is he sample program:

And what have you got in the way of software? You did purchase a PBP Compiler... it doesn't come free with your ICD2...

[dirkwerk]

I purchased it but i wanna use mplab cd2 because it was delivered with my picdem board

[dirkwerk]

no much help in here

There's lots of help here, but you need to be a tad more specific.

Are you compiling from within MPLAB or MicroCode Studio?

Do you have MPASM or PM selected as the assembler?

Which version of PBP do you have?

i looked on the web for 16F877A.BAS file

Have you looked in your PBP install directory?

[dirkwerk]

hope someone can help me im trying nos for 2 weeks
but thank already for the reply.

Im compiling within MPLAB

I have selected the PBPW as the assembler
Which version of PBP do you have?

procompiler 2.46
16F877A.BAS is not in my pbp directory

[Bruce]

Support for the 877A was added back in version 2.42. If you can't find 16F877A.BAS in your
PBP directory, then you should re-install, or contact the distributor you purchased PBP from.
They should be able to help you if there are missing device header files on your original PBP
install disc.

PBPW is not the assembler. It's the Windows version of the compiler EXE. In MPLAB, with PBP
setup as the language tool, you have the option of selecting PM or MPASMWIN as the
assembler.

But you will need to get familiar with MPLAB if you're compiling PBP programs using this IDE.

Assuming you have installed PBP correctly (as shown in your PBP manual), you have the path
setup, and PBP setup properly within MPLAB, you should not have any problems getting it to
compile in MPLAB.

What i only see in my pbp directory is the pbpw.exe file could be a problem with
the installing disc. Its a disc i get from a friend who did not need it any more
and for me it was a good to see if it was better to program in picbasic
but without that 16f877a.bas file i cant do nothing and buying again that program
without knowing it will work is to expensive, is the 16f877a.bas the only file im missing then?

Thanks very much
Dirk

[Bruce]

No. You will need a great deal more than just pbpw.exe and a .bas header file.

That's what is so nice about actually purchasing legal copies. You get full support, and a
compiler that actually works.

[dirkwerk]

I gues it is a legal, but there is something wrong with the disc i guess,
thats probaply why he give it to me but the only thing is nnow that i catnt
test it

Thanks very much
Dirk

[Bruce]

If you can't get the files you need from your friend so you have the full working version, you
can still test drive the compiler. Just download the demo. It supports the 877A.

I gues it is a legal

Read the yellow section on this page http://www.microengineeringlabs.com/...pgrade.htm#pbp

but i dont see any 877a.bas files.

[Bruce]

The demo version is a bit different, and does not install the same files. Run it, and try it.

[dirkwerk]

ill try i tommorow, but important is for me that it works with the ICD MPLAPS

see tomorrow

[Bruce]

I don't think you will be able to run ICD2 without ICDDEFS.BAS which is required to reserve
ICD resources. Like any demo, there are limitations as compared to the full version.

You can however use the ICD2 as a device programmer with no problem.

I'm using the PB Pro demo with MPlab 8.0 using Mpasmwin and ICD2 and the Picdem 2 Plus(older version 2002). The only problem I had was a path problem. I'm using a 16F877 and it gave some message about finding the P16F877.inc file. I setup my path for PB pro and the mpasmwin directories but it didn't help. So for a temp solution, copied, then modified the 16F877.inc file with the full path. Works great now.

Other than that the demo works fine and you will find that 31 commands is a big limitation. I liked the demo, so I order the full version today, hopefully MElabs are a fast shipping company.
