outputsplitter

Chris79

I have a problem. (I´m a beginner)

I´m using 3 ULN2803 to control 3 steppermotors. (I´m planning to use more steppermotors and more ULN2803·later on) and I have 2 of the ULN2803 to pin0-pin3 But I can´t split the outputs from the pins so pin0 and pin1 goes to one of the ULN2803 and pin2 and pin3 goes to the other. Every time I try to control for example the one that is connected to the BS2 through pin0 and pin1 the other stepper motors tries to start also and vicer versa. How can I split the outputs so· pin0 and pin1 goes to one and pin2 and pins3 goes to the other, so i can control the stepeprmotors the way I want

Chris -

It's a bit unclear exactly what you're trying to do since we haven't been told what the purpose of the pin ports are, nor where they're wired to. However, even without that information, I suspect you're going to need two pin ports for each stepper motor, or 4 pin ports for two stepper motors.

I know it was a bit fuzzy the way I explained it all, but as it turned out, the problem was in my code. I fixed it now. Thanx any way
