Adam, as you progress I would like to offer some assistance when you reach a point where you can share some of the source. I too have similiar "other" obligations but will try what I can.

I am the one that started this thread originally. After reviewing all the documentation available at the Basic Stamp Club's site as well as Chuck McManis's document on decoding the BS1 as well as the stuff on the Dontronics site, I have decided to try and roll my own Stamp clone using a 16F84. The reason? I didn't find any source code, I don't want use an AVR, Scenix, Motorola, etc. microprocessor, and besides it just looks like a fun challenge. As a starting point I have a BASIC interpreter from a Herbert Schildt C programming book that I think I can modify and use as the "tokenizer" for the input BASIC code, and can modify and use the algorithms on the PIC for the interpreter (I might even use CC5X for the interpreter). I intend to simplify the encoding scheme so that it is byte oriented rather than bit oriented. It will also be flexible in that you can use up to a 65K eeprom for storage if you need that much space or a 256 byte eeprom if that's all the storage you need (In other words I will use a full 16 bits for addresses). I also think it should be possible to add some instructions (PWM out?) that take advantage of interrupts, but I haven't thought this one through yet. I also have in mind a few other instructions I would like to add to the BASIC instruction set. I will definitely be sharing the result of my efforts (FREE, AND INCLUDING SOURCE CODE) as I work on this. However, I have 3 kids, a wife, a house, and other hobbies, so no promises on when you might see something. Adam On Thu, 16 Dec 1999 09:55:51 -0600 "Giles L.
