UDN2559-based control board going
OK, I've got the resistors a factor of 10 out on the opto sensors on the first board, but I'm not using those anyway yet :) I'll fix that later. The main problem with the new board was a track cut in the wrong place - took a while to figure it out.
Now to modify the original board to use the new opto layout, and right resistor values. Then I should be able to control 2 motors. If that works I'll rearrange the bus to use the new power line arrangement Simon and Adrian figured out.
I've bought more stripboard, so hopefully I'll have 3 motors controlled soon.
It's still pretty beta so I'm not publishing yet. If anybody really wants the "how to" files though, mail me under caveat!
Vik :v)
