Linux/Win-Compliant C PIC Prog

MIOS programming (Assembler)
1

I’ve been using some PIC16F876A µC’s at work for one month now, with MicroChip’s PICSTART Plus hardware & MPLAB software and PicAnt C2C compiler. Easy way but not for cheapskates… I’d like to find a low-cost solution for my own projects (including MIDIbox ones, that’s why I’m here), running on Linux (and Windows if available), in C not ASM!

When it comes to hardware, I’ve been thinking of C. Tavernier’s or El Cheapo’s designs. Should the SourceForge couple (SDCC & PP06) help handle that situation, PIC16F support seems to be on its earliest stage… Any replacement idea?

I use GPASM (http://gputils.sourceforge.net) with SDCC and mios C wrapper, I post a makefile on another thread. It works great :wink:

I’ve found the aforementionned makefile on the topic “Status of SDCC evaluation” (for those who read posts silently on their own):

project.hex:      main.c 
       gpasm -c mios_wrapper/mios_wrapper.asm -I mios_wrapper -o mios_wrapper.o 
       sdcc -S -V -mpic16 -p18F452 --pomit-config-words --pomit-ivt -pleave-reset-vector main.c  
       perl tools/fixasm.pl main.asm 
       gpasm -c main.asm 
       gplink main.o mios_wrapper.o -s project.lkr -o project.hex 
       perl tools/hex2syx.pl project.hex

I think I can guess how to remove occurences of the MIOS C Wrapper above as I ain’t into MIOS programming for the moment. I’ll still be notfied of updates on the other topic for future projects.

Thanks!

Here’s a better one I think :wink:

project.syx:    main.c mios_wrapper.o
        sdcc -S -V -mpic16 -p18F452 --pomit-config-words --pomit-ivt -pleave-reset-vector main.c
        perl tools/fixasm.pl main.asm
        gpasm -c main.asm
        gplink main.o mios_wrapper.o -s project.lkr -o project.hex
        perl tools/hex2syx.pl project.hex
        mios_upload.pl project.syx

mios_wrapper.o: mios_wrapper/mios_wrapper.asm
        gpasm -c mios_wrapper/mios_wrapper.asm -I mios_wrapper -o mios_wrapper.o

upload: project.syx
        mios_upload.pl project.syx

Thanks again!

When using Windows, it’s more to be considered as a *.bat script than a makefile, isn’t it?

Why don’t you use PP06 instead of GPASM?

Yes I think, but I don’t know windows very well.

PP06 is for programming the chip? gpasm is a pic assembler (needed because SDCC output asm). But I didn’t know PP06, I will look after it now :wink:

I use Pikdev for linux, works fine with the midbox design of the JDM. There is a decent open source C compiler in the works too, but I don’t think it’s done yet.

And gvim for writing the source code, it has syntax highlighting for Microchip Assembly, cool!

kwrite has this feature too :wink: (and emacs has got an asm mode too)

This is not SDCC?

I haven’t taken time to test it all… Haven’t made my choice on the harware programmer either! Any fave here? The JDM module?
