Additionally, there are more pins in order to distuinguish between full and part step modes.
I tried to emulate this with an up-counter, which counts up on every "STEP" and a RAM/ROM IC, which contains the distinct voltages on A+, B+ and A-, B- for each step.
Since the stepper in Simulide already work with 5V I thought the output of the RAM/ROM IC should already work as driver. Additionally, I tried an impedance conversion via a buffer.
Without a buffer the stepper motor often jumps back and is not able to make a full turn. With the buffers it's much better, but there are still some back-steps visible.
How could this be solved?
