LED matrix

I have succesfully interfaced the LED matrix with a PC via the serial port. The software on the PC-side sends frames to the matrix, which displays them. You can toggle a LED by clicking on a 10x10 grid on the PC side of things. By default, the program operates in 'batch mode': it sends a new frame only when you press a button. But there is also a 'direct mode' which directly updates the frame in the matrix when you click on the grid.

I think the protocol that I came up with is pretty robust, so when any mistakes occur, the software should be able to reset the PIC into a valid starting state. Of course, it needs some additional polishing, but at least the basics all work!
