C compiled part inside assembler
PostPosted: Mon Nov 14, 2005 2:40 am     Reply with quote
Hi everybody,

I have an old project compiled in assembler with MPLAB. Now I want to include a new part compiled in C.

1) Is it Possible ?
2) Is there any example somewere ?

Thanks for support,

Regards,
PCM programmer

The CCS compiler doesn't (yet) produce linkable object modules.
You would have to use a different C compiler.

Here is a thread on the Microchip forum on the topic:

mixing C and assembler

I'm using CCS PCH v3.214 with MPLAB 7.10 and MPASM etc 3.90.01.

The project was originally written in assembler, and then some floating point stuff was added using C. I have the source but not the tools. My tools (above) won't compile/assemble and link this.

Do I need different tools?

Either get new tools, or convert the ASM code into C.

If you have the assembler source code you can use CCS's mini assembler and embedd the code in your C code.

Yes, but people are always complaining that they can't
do everything they want with the CCS inline assembler.

On one hand I agree with them. It is a pain that it doesn't , especially not supporting all the FSRs, but on the otherhand its not rocket science to change the affected code.
