I think I figured this out. My steppers are of the six-wire variety so it appears that I should be able to use them. My ignorance....
Another question - I need a solution that is very low RFI, because I am building an automatic antenna tuner unit. I can shield the motor wires in braid, so that should be no problem. I have had problems in the past with 2-wire serial interfaces generating massive RFI, however. I had to get rid of the wired controller for my garage door openers because they were so noisy. Ironically, the wireless controllers produce much less RF than the wired ones! I have not used SPI before. Can I expect it to be a problem?
Can this product be used to control unipolar steppers? Or is there another product for Arduino recommended for this purpose? hanks!
No public wish lists :(
