A49xx/DRV88xx stepper motor driver
Stepper motor driver that supports A49xx and DRV88xx families of stepper drivers.
Example
#![deny(unsafe_code)]
#![deny(warnings)]
#![no_std]
extern crate panic_abort;
extern crate cortex_m;
extern crate embedded_hal;
extern crate tm4c123x_hal as hal;
extern crate stepper_rs;
use hal::delay::Delay;
use hal::gpio::GpioExt;
use hal::sysctl::SysctlExt;
fn main() {
let p = hal::Peripherals::take().unwrap();
let sysctl = p.SYSCTL.constrain();
let portc = p.GPIO_PORTC.split(&sysctl.power_control);
let clocks = sysctl.clock_setup.freeze();
let cp = cortex_m::Peripherals::take().unwrap();
let mut driver = stepper_rs::MotorDriver::a4988(
Delay::new(cp.SYST, &clocks),
portc.pc6.into_push_pull_output(),
portc.pc7.into_push_pull_output(),
200,
16,
100f32
);
loop {
driver.set_speed(100f32);
driver.set_direction(true);
driver.move_instant(600);
driver.set_direction(false);
driver.move_instant(600);
driver.set_speed(300f32);
driver.set_direction(true);
driver.move_smooth(1600, 150, 150);
driver.set_direction(false);
driver.move_smooth(1600, 150, 150);
}
}
TODO
- Implement EN pin handling (enable/disable the driver)
- Implement driver specific functions (for example, setting a step division by pins)
- Refactor
hal::delay
into properly configured timer when embedded-hal will get more consistentCountDowm::Time
restrictions.
