Can anyone help me please; I am desperately looking for some example on how to interfacing Stepper Motor through A4988 Stepper Motor Driver Module with Arduino using FreeRTOS? There are other tasks to run concurrently too.
Stepper motor controllers aren’t that hard to use, basically you just need to pulse the step line at the rate you want to step the motor. Depending on the speed you are trying to get, it could be as simple as scheduling a timer to call a function to toggle the step line at the rate you need. That will limit you step rate to 1/2 the tick frequency.
If you need faster, you need some time base faster than the system tick.
