esp_pwm_reader
Wrapper around the mcpwm capture module for reading pwm signals.
Documentation
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); } }
