ESP IDF Servo Library

Introduction

This crate is a simple wrapper over the esp-idf-sys bindings to make servo control easier using the LEDC module.

Basic Usage

Create a basic Servo Configuration - this one specific for the SG90 series of servo motors.

``` let peripherals = Peripherals::take().unwrap();

let servo_cfg = ServoConfig {
    max_angle: 180,
    min_width_us: 500,
    max_width_us: 2500,
    frequency: 50,
    timer_number: ledc_timer_t_LEDC_TIMER_0,
    pin: peripherals.pins.gpio0.pin(),
    channel: esp_idf_hal::ledc::CHANNEL0::channel(),
    speed_mode: ledc_mode_t_LEDC_LOW_SPEED_MODE,
};

```

Initialize the servo:

let servo = Servo::init(servo_cfg);

Change the angle of the servo within your program:

``` loop { for i in 0..180 {

        servo.write_angle((i as f64));

        FreeRtos::delay_ms(20);
    }

    for i in (0..180).rev() {

        servo.write_angle((i as f64));

        FreeRtos::delay_ms(20);
    }
}

```
