This code is branched out of my M0RJCTracker repository. It is becoming big and, with a little work, will become sufficiently generalised to be useful in its own right.

The state machines are intended for parsing input, for example coming over a serial port from a GPS receiver module or a controlling PC. A particular feature of the model to support this is that unknown input will cause it to revert to its initial state.

Currently the sequence of operations is:

• Write a Java class which builds up a StateModel.
• Create the necessary builders for the desired output.
• Pass them to the model's accept() method.

The builders are

• DiagramBuilder outputs a Graphviz .dot file to allow visualisation of the model.
• SimulatorBuilder creates a simulator designed to allow unit testing of the model.
• PicAsmBuilder, when written, will create the PIC assembler file. I expect to write three builders, for ASM, INC and H.

I have a working unit test simulating a model built using Java code.

I have a reader for an XML definition file.

I have what looks like a working PIC18 Assembler builder. It needs testing.

Create an acceptance test:

• Define a State Model in an XML file
• Combine this with some support code and program it onto a PIC
• Write JUnit tests which interact with the PIC and the running state model over the serial port.

Create at least a simple UI to run files. Maybe one day a UI to edit them.
