步进电机C实现

Question

Been unsuccessful in finding this answer elsewhere.

Is there a typical way to implement stepper motor, Accel, velocity and speed control in C?

The clock speed doesn't seem quick enough to toggle a step pin each loop. Do people normally use a CTC interrupt and change the timer compare value? I want to move a certain amount of steps at a definable Vel and Accel.

Any help would be greatly appreciated!

Answer 1

Time ago I wrote a C device driver on an STM8S microcontroller for a 24 VDC Sonceboz stepper motor.

Between the CPU and the motor I put an L6219 stepper motor driver.

The CPU clock was 8 MHz.

I used a hardware timer that every 10 ms fired an interrupt.

Within the interrupt function there was my code that drove the L6219 driver.

The CPU time spent in the interrupt function was less than 20 micro seconds.
