Arduino / ATMega stepper motor control in C++

Rudamentary stepper motor control with linear start/stop speed ramps.

Small demo: https://youtu.be/yUwn1LcOEcw

Control one or more stepper motor drivers that have an 'enable, direction, step' interface. Linear start/stop speed ramps for smoothisch movement.

Building/Installing

Dependencies

apt-get install avc-libc avrdude

Building and flashing

make
make install  # Assumes your bord is attached to /dev/ttyUSB0

Classes

GPIO

gpio led(gpio::portb, gpio::pin5, gpio::out);
led.set();

Motor

gpio ena(gpio::portd, gpio::pin2, gpio::out);
gpio dir(gpio::portd, gpio::pin4, gpio::out);
gpio pul(gpio::portd, gpio::pin6, gpio::out);

Motor motor(pul, dir, ena);
motor.enable();
motor.step();
motor.ccw();
motor.cw();
motor.disable();

Control

Control control(motor, 250, 8000, 4); // motor, start steps/sec, max steps/sec, ramp angle)
control.move(4000); // Rotate shaft CW 4000 steps
control.move(-4000, 2000); // Rotate shaft CCW by 4000 steps @ max 2000 step/sec
