Thread: Forth system for the PIC?

I have written Forth for two microcontroller chips, the SX28AC and the
16C73. They work by treating the microcontrollers internal program area like
microcode. External SRAM, serial EEPROM, UART's, and other peripherals are
accessed via a multiplexed data-address buss. Writing it was lots of fun.
I'm in the process of writing code that handles low-level interrupts using
high-level Forth definitions so eventually every subsystem will be available
to the user. So far I hav'nt written a seperate compiler, just the
interpreter-compiler that's standard with any Forth system. I'm working on
it though...
