Finally, here are the sources I was talking about for so long! This project page wouldn’t be complete without it, would it?
The zip file below contains complete sources of AVR firmware in Arduino language (C++ with a couple of libraries, basically), the graphical development environment, a sample control program with corresponding configuration, a simple PC SCADA application and a simple communication library in Java.
Schematics and other info can be found (just search in the document, you’ll find it at the end).
It looks like that:
Do read more about it .
Here it is! The AT90USB646-based homebrew programmable logic controller. It’s not quite a (and it’s not even completed in some parts), but it’s a nice start. A more complete and IEC-ish environment on the development software part (among many other things) would be nicer, but… the code is (will be) here, so extend it to whatever you want. But, whatever you may want to do with it, keep in mind it’s more of a “proof-of-concept” thing than a production-ready device.
