Re: [Amforth-devel] Connection to host

That would be great.

It may (or may not) be useful to take a peak at the ICSP programming 
code for the arduino.

It can be found in the example code for V18 of the arduino IDE and is 
called ArduinoISP. This emulates the AVR ISP I think using the STK protocol.

Certainly there is a whole bunch that can be trimmed out for a more 
simple clone function ie the STK protocol and a whole bunch of the host 
comms code.

It is written in C and I am certainly not suggesting doing similar. It 
would be useful though to pull apart and understand the programming 
algorithms and bit banging etc though.

An optionally overridden check of the device ID's could be used to 
ensure that a successful clone is possible.

I was sugesting overridden because Atmel do have a habit of bringing out 
new variants of their processors that are directly compatible but have a 
different device ID. I am thinking of the "p" or low power variants 
here. ie the 644 and 644p are 100% compatible code wise from 644 => 644p.

If you already had a bunch of this covered, sorry. Not knowing I thought 
it better to contribute just in case it was of some use.

Cheers

PS off to play some more with getting amforth onto an Arduino Mega 
(ATMega1280). I have got it assembling and loading but does not yet run.
