PICForth

PicForth is a really nifty little Forth implementation for the 16F87x and 16F88 processors, written by Samuel Tardieu. I had a Microchip PICDem.Net board that I borrowed from a friend.

I wrote a handful of little demo programs for PicForth, located in the Subversion repository, linked to below.

These demonstrate using the various peripherals and PicForth features, such as the

• ADC
• I2C
• LCD
• Serial ports
• Forth tasking

Note: While PICForth is still available, it hasn't been updated since 2004. Unless you're already locked into a 16F87X or 16F88 processor, you may want to consider rforth, by the same author. Features of rforth include:

• Native compilation (no virtual machine)
• 16 bits cells
• Optimized generated code
• */ scaling operator with 32 bits intermediate result
• Postfix and prefix integrated assembler
• Written in Python (is that really a feature?)
