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);
  }
}
