googlie:
I am generating step and directions on PWM pins which are connected to a parallel breakout board.
This (http://probotix.com/ready_to_run_driver_options/ ) is what powers the stepper motors. So I only need to generate a tone and direction signal to operate the motors. I am having trouble seeing where the confusion lies. I have done this in the past. All this post was inquiring about as if I could control motors using an array.
Either that is a new way to drive stepper motors that people here are not familiar with or you are failing to give us some necessary information.
Most people use one of the Arduino libraries to create the signals for a stepper motor. In the case of a stepper driver that only needs step and direction inputs it is trivial to generate them with a digitalWrite() to the relevant pins. I am not aware of anyone using PWM to generate the step signals - how would you control the speed or the precise number of steps that way?
Without understanding how you are driving your motors it's difficult to understand how you plan to use the data in the arrays.
Iterating through an array is the easy part. For example ...
for (byte n = 0; n < 3; n++) {
byte xx = array[n];
if (xx == 1) {
// do something
}
}
Use nested FOR loops to iterate through a multi-dimensional array.
