I was working at trying to find the bug in PIC-based controller board for Tommelise and finally stepped back and looked at the thing.
This is ridiculous. The whole thing is patches from various things that I tried that didn't work just right for one reason or another. Not only that, it's enough to scare the wits out of anybody contemplating making their own Tommelise. The Tommelise motherboard only has three integrated circuits (IC's), One Microchip PIC 18F4610 and two Texas Instruments 754410 dual Darlington chips. How simple can you get?
I don't make elegant boards, as you can see. The new one I'm building, however, ought to be a LOT less intimidating that this one.
