Go Forth on a Breadboard
Forth isn’t a shiny new programming language, but it has a staunch following because it is lightweight and elegant. The brainchild of [Chuck Moore], the language is deceptively simple. Words are character sequences delimited by spaces. In its simplest form, Forth knows a few basic words including–and this is the key–a word to define other words. [Jean-Claude Wippler] likes to experiment with physical computing and he found a Forth image ready-made for the LPC1114 . Why is that interesting? The LPC1114 is one of the few (or maybe the only) modern ARM processor in a breadboard-friendly DIP package. Since [Jean-Claude] had a chip sitting around, he had a Forth system up in no time. All he needed was a breadboard and a 3.3V serial connector. The chip has its own bootloader and the The Mecrisp-Stellaris Forth he used has over 300 words as well as the ability, of course, to add ...
