# esp_pwm_reader

Wrapper around the mcpwm capture module for reading pwm signals.

# Documentation

- see 

  

# Usage

- you need to create a capture timer which can then be used by multiple channel readers

- f.e.

  ```

  use channel_reader::{CaptureTimer, ChannelReader};

  use esp_idf_hal::delay::FreeRtos;

  use esp_idf_sys::{

    gpio_num_t_GPIO_NUM_16, gpio_num_t_GPIO_NUM_17

  };

  fn main() {

    let capture_timer = CaptureTimer::new(0).unwrap();

    let channel1 = ChannelReader::new(&capture_timer, gpio_num_t_GPIO_NUM_16).unwrap();

    let channel2 = ChannelReader::new(&capture_timer, gpio_num_t_GPIO_NUM_17).unwrap();

    loop {

        println!(

            "ch1: {} ch2: {}",

            channel1.get_value(),

            channel2.get_value()

        );

        FreeRtos::delay_ms(11);

    }

  }

  ```
