Post by thread:Free PIC16C84 C Compiler

-----BEGIN PGP SIGNED MESSAGE----- Well, I checked out John Favata's free C compiler for the PIC16C84. Now, I've got good news, so-so news, and bad news... The good news is: o It's available in full C source. o It's a port of Small C, so it's well modularized. The so-so news is: o It's only targeted towards the PIC16C84. The bad news is: o It generates pseudo-8051 assembly code which (as far as I know) is only usable with the Parallax PIC16/17 assembler. :-( I don't have anything against Parallax, nor against their (probably spiffy) assembler... except for the fact that I don't have a copy. It's not free, is it? I certainly wouldn't want to spend money on an assembler that's generally considered less capable than the free one (MPASM, the *standard*) from Microchip. Is there any way to convert Parallax-ish pseudo-8051 assembler into standard (MPASM) code? Does anyone know of any documentation available which would help me re-code "pic_cc" to output normal PIC16C84 instructions???

It was targeted to PIC16C84 because there was enough ram on chip to implement a small stack. Porting the compiler to the 5X family may take a little more work because of the limited stack depth and paging problems.... The compiler was posted as a starting point for people to hack into whatever C compiler tool they need. As it is, it can be converted to generate MPASM instructions easily. I do pattern recognition research for a living, not compilers... 8-) jf

However, some people like our cute, little assembler. It's available at ftp.parallaxinc.com/pub/parallax/pic_lite.zip. This zipped file contains several files, including our PASM.EXE (16C5x) and PASMX.EXE (16Cxx) assemblers at no charge. Michael J. Robin
