PicForth, a Forth compiler, generates code for the Microchip PIC 16F87x and 16F88x microcontroller families. It is hosted on Unix (or Linux) using GForth 0.6.x. It includes two kinds of cooperative schedulers. You can download PicForth 1.2.5 from http://www.rfc1149.net/devel/picforth . PicForth is available under the GPL free software license.

In the distribution, you will find some examples: a model railroad booster, a DCC signal generator, some code for silver card smartcards.
