About

CamelForth

A Forth in C by Dr Brad Rodriguez

Forth interpreter for the RP2040 and Raspberry Pi Pico.

Requires pico-sdk and is modeled on pico-examples.

The /dev/ttyACM0 is the primary interface (USB).

(Reference host PC is Linux Debian amd64)

Using CP2104 USB-to-USART bridge, the secondary interface (in Linux host PC) is /dev/ttyUSB0, but that is arbitrary (you can bridge using other methods and chips).

Connected to UART0 on the pico.

BUILD ENVIRONMENT - bare bones text interpreter

no Forth functionality at all - not even base code.

Just keyboard echo loop.
