got it.
I see it now… I had to scroll to the right to see it.
Try removing the capacitors
Try removing the capacitors on the outputs, or move them to go across the outputs instead of to GND.
I thought of that too, ezekiel
I guess caps are great and I also guess you can’t have too many of them but for the sake of testing and simplifying, it sure does seems that there are a lot of them in that schematic. Again, I have no idea if they would/could ever pose any kind of problem but when stuff does not work for me, my response is always to get the problem down to the least number of parts and the smallest amount of code. I think something very simple is being missed here.
Yeah, typically motors will
Yeah, typically motors will have a capacitor across the leads, not to ground. For additional noise suppression caps can be wired between each motor terminal and the motor case. I usually use 0.1uF @ 50V for this purpose since I have a few hundred laying around. The way you have it will create an AC short to ground from each of the Y terminals of your chip, which sounds like it should work fine for noise suppression.
