Post by thread:[PIC]: Free stuff for PICs

I am looking for some free stuff I can use in the IEEE robotics club at the U of S to allow beginners to program PICs. Here is what I want: GNU basic compiler, must support 16f87x, can be a limited version. I.e. Free to 1k or 2k. This will only be used to write simple programs. GNU C compiler same criteria as the basic compiler. Programmer schematic. Something simple, that will hopefully support ICP. Again must support 16f87x _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- http://www.piclist.com hint: The PICList is archived three different ways.

If you mean ports of the GNU-basic and GCC compiler: forget it. Search the archives for the reasons. If you mean GPL-covered basic & C compilers: be sure to let us all know when you find them! If you mean a free compiler there are a few C compilers that have free demo versions (HiTech for 16x84 only, BKD C for all PIC up to 1K?). > Programmer schematic.

Hi. As far as a free compiler goes, CC5X is great.. It supports up to 1K-word programs and is reasonably efficient even with the demo optimizations. As far as a programmer goes, http://jaichi.virtualave.net/pic16f8xx-e.htm (great software) and AN589 from Microchip. Note: If you are using a Low-voltage programmable Chip, then AN589 can be modified somewhat. The whole programmer I use is ICSP capable, Low-voltage and consists of just a 244 buffer. That's essentially what AN589 says without all the stuff for switching 13V! Hope that helps. - Wade {Original Message removed}

C compiler: c2c http://www.geocities.com/SiliconValley/Network/3656/c2c/documents.html Runs under DOS, Windows and of course Linux. Produces assembly which can be further tuned or directly compiled into a hex file using gpasm (http://www.gnupic.org) or mpasm. I haven't actually used it for anything large, so I don't know if it includes everything you could ever need, but for those other cases you can write inline assembly I guess :-) Compiles for many many chips, including the 16f87x A schematic for a programmer, have a look at NOPPP at http://www.covingtoninnovations.com/noppp/com/noppp/ Schematic is pretty simple (remove R6 though! I had to anyway :-), it has software for Dos, Windows and again Linux. It does not target the 16f87x, but can be easily modified. (i.e. the pin connections are the same, so instead of wiring to MCLR on the 16f84, wire it to the MCLR on the 16f87x, same for RB6, RB7, VDD, VCC etc. Actually, just read this page :) http://patearl.net/pic_html Depending on your audience you might still want to go with commercial test boards that allow lots of experimenting, programming etc. Regards, Dennis {Quote hidden}> If you mean a free compiler there are a few C compilers that have free demo > versions (HiTech for 16x84 only, BKD C for all PIC up to 1K?). > > > Programmer schematic.

Hmmzzz, what have I been smoking :-) Still free to use though. Regards, Dennis -- http://www.piclist.com hint: The PICList is archived three different ways.

As far as difficultly - well for me the hard part is the compiler, not the target CPU. Things like data stacks and better addressing would make things easier, but Hi-Tech, ByteCraft, and C2C show that it's not necessary.

There is a free version of my basic compiler available at http://basic18.piclist.com Unfortumately it only works for the PIC18Xxxx series.

David, i'm interested in your opinion, but the use of the "c" word (you know the one) is not really needed and it's such an ugly word in this context. I prefer to express myself with less ugliness and maybe some humour when "extreme" concepts need to be communicated. :o) -Roman -- http://www.piclist.com hint: The PICList is archived three different ways.
