The new greatly simplified controller works. It will also enable
experimenting with ds boards. Here is a link to a panel I just made
of 4 of the new mcu boards. The minor smudging at the bottom of the
board is an artifact - The toner was printed slightly on the tape
holding the board to the carrier. The traces are 10 mil wide. I will
post the new schematic in the next day or so.
