PIC Micro Controller Languages

• ASM

  Many years ago everyone used assembly language because there was no alternative. A few years ago many people used assembly language because the alternatives were expensive. Now there are lots of alternatives, many of them free. Still, many people use assembly code because (a) inertia -- they've been using it for years, why change now ? (b) there are a few esoteric things that are cannot be done in any other language. ( writing native-code compilers, writing task switchers, squeezing code to minimum size, writing isochronous code )

• Pascal-like
  • JAL a Pascal like compiler produces .hex and MPASM .asm files (free) Now open source under GPL! See Getting started with JAL. See /techref/piclist/jal/jpwm.htm. Many people have written code in JAL. Much of that code is now available at the JAL libraries repository which also hosts the JAL wiki.
  • PMP (Pic Micro Pascal) http://www.pmpcomp.fr is a free Pascal cross compiler for PIC processors. There is a new Pascal compiler for Pic: PMP ppater-club_internet- replies: PMP now supports PIC10, PIC12, PIC16 and PIC18, floating point library for PIC18. Enjoy!+

  • XPL0 An excellent open source byte code interpreted language that will run on the following processors: 6502, 8080, 6800, PDP-10, IBM-360, a homebrew machine, 65802, 680x0, PIC, SX28, and the 80x86 family used by the PC. GUI support and win32 versions are also available.
  • mikroPascal " Have a look at this amazing new Pascal compiler for PIC MCUs: http://www.mikroelektronika.co.yu/english/product/compilers/compilers.htm

• Basic

  (XCSB, Basic Stamp, BS/4, Great Cow, etc.)

• C/C++

  There are quite a few different versions of C available for the PIC. Some of them are free. See language/cs.htm for details.

• Forth
• Java
• Python

  PICList post "Python for PICs" mentions the PYthon to ASsembler TRAnslator http://sourceforge.net/projects/pyastra/ for Microchip PIC16.

Questions:

• jamie@spam@ at @spam@i-technologyinc.com asks:

  Looking for older compiler for some old PIC source that needs a like updating. It is a sturctured type of assembly language called "mc macroassembler". This program was developed by "Microtec Research" and "AMD" back in the eary 1990's. "Microtec Research" is long gone as brough by "Methor Graphics" in 1995. I have some of the pieces need to compile the source but not all.
  
  Do you have the "MC macroassembler" by "Microtec Research" used to compile this source ?

• asks: " Have any person code for read and writte a sle4442 memory card with a 16f8XX."
• gbetts@spam@ at @spam@aracnet.com asks:

  Looking for a copy of the old MicroChip Fuzzy compiler. At $2000 the new one they recommend is a little past my budget. Have one you're not using, I'd like to buy it. Reply direct to gbetts@aracnet.com
