If you have been wondering what I have been up to this morning, and I am sure you have, then the answer is the graphic below. It is a circuit board I am attempting to design for a project – the most complex one I have designed for a while. It has a microprocessor module on it, and a couple of RS232 ports, and that is about it. It is designed to allow me to interface between two significantly different systems without needing to put a PC in between. Basically, it is a swiss army chainsaw.
