They are uni-polar (6 wires) And I need to control all 10 individually using one PIC.
I'm really good at PIC programming and I basically have most of the logic sketched down, but it's the external hardware that's giving me the problems.
I'm using the MC3479P. Everything runs well during initial testing if I use one of these chips. But if I connect two of them, one shorts and blows up in my face.
Can anyone help?
(also: what do I do if I need to power a larger stepper motor [like 1amp]? these chips only source something like .4amp)
