So instead of using the Toggle command to abbreviate the coding -not competent enough to really understand yet, I wanted to start off programming all four coils independently to learn how to do it. The driver board which came with the motor referenced above has a plug for the motor which has five leads, pins for four inputs from the controller, and a ground and power pin. The coding online for similar devices (can not read Chinese) that I can find shows eight steps
(which I can only assume is just repeated)? At the bottom is my code for these eight steps.
Result: It turned about 20deg over a long period of time- could not see movement with naked eye. Also LED lights for each motor leg do not make sense with inputs.
I took the eight steps below to be the inputs to the driver board from my controller-If they are the outputs from the driver board to the motor should I code the controller as if below values were inverted ?
The following picture is the control signal to drive a 28BYJ48 stepper to rotate 1/4096 circle.
