error: could not compile `uart` (bin "uart") due to 1 previous error
Hello,
I am trying to run Embassy on an ESP32, not ESP32C3. I was able to run the examples from the esp-hal repo, but I wanted to write something from scratch. I tried using code from your repo but looks like it's not working because it targets the wrong arch for my use case.
I would really appreciate it if you could provide some ESP32 examples as well!
While compiling, I got the below error which was fixed by updating the config.toml file to say rustflags = ["--cfg", "espidf_time64", "-C", "default-linker-libraries"]. I was trying to compile this example.
You can use an array instead of declaring 10 variables (one variable by pin!).
Then you will be able to iterate the array with a for loop.
// Configure all LED pins to digital outputs
let mut leds = [
PinDriver::output(dp.pins.gpio1.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio10.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio19.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio18.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio4.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio5.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio6.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio7.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio8.downgrade_output()).unwrap(),
PinDriver::output(dp.pins.gpio9.downgrade_output()).unwrap(),
];Put the following code in the main loop :
for mut led in &mut leds {
// LED n
led.set_high().unwrap();
blinkdelay = button_pressed(&button, &blinkdelay);
FreeRtos::delay_ms(blinkdelay);
led.set_low().unwrap();
FreeRtos::delay_ms(100_u32);
}I have tested the result on wokwi : https://wokwi.com/projects/370781756466770945
Hello Omar,
I read your blog on the ESP32 Standard Library Embedded Rust: Timers.
I was trying to factorize the code like following :
use esp_idf_hal::gpio::*;
use esp_idf_hal::peripherals::Peripherals;
use esp_idf_hal::timer::config::Config;
use esp_idf_hal::timer::TimerDriver;
fn main() {
esp_idf_sys::link_patches();
let peripherals = Peripherals::take().unwrap();
// Configure and Initialize Timer Drivers
let config = Config::new();
let mut timer1 = TimerDriver::new(peripherals.timer00, &config).unwrap();
let mut timer2 = TimerDriver::new(peripherals.timer10, &config).unwrap();
// Configure Pins that Will Read the Square Wave as Inputs
let pin1 = PinDriver::input(peripherals.pins.gpio0.downgrade_input()).unwrap();
let pin2 = PinDriver::input(peripherals.pins.gpio1.downgrade_input()).unwrap();
// Declare and Init Variables that will Track Pin level
let mut pin1_old_level: Level = Level::Low;
let mut pin2_old_level: Level = Level::High;
// Set Counter Start Value to Zero
timer1.set_counter(0_u64).unwrap();
timer2.set_counter(0_u64).unwrap();
// Enable Counter
timer1.enable(true).unwrap();
timer2.enable(true).unwrap();
loop {
pin1_old_level = measure_pin(&mut timer1, &pin1, 1, pin1_old_level);
pin2_old_level = measure_pin(&mut timer2, &pin2, 2, pin2_old_level);
}
}
fn measure_pin<T: Pin, MODE: esp_idf_hal::gpio::InputMode>(timer: &mut TimerDriver, pin: &PinDriver<T, MODE>, index: u8, pin_previous_level: Level) -> Level {
// Get Level of pin
let pin_current_level = pin.get_level();
if pin_current_level != pin_previous_level {
match pin_current_level {
// If pin level changed from Low to High then reset count
Level::High => timer.set_counter(0).unwrap(),
// If pin level changed from High to Low then capture count
Level::Low => {
let count: u64 = timer.counter().unwrap();
// Calculate and Print Out the Pulse Width
// Clock Frequency is 1 MHz According to Code
println!("Sq Wave {} Pulse Width is {:.1}ms", index, count / 1000);
}
}
}
pin_current_level
}I test it with Wokwi and the time accuracy is more precise (and take less emulated CPU).
First, I wonder why, then I understand that you print several time the same count at each iteration loop.
In my revised code, I only display the count, when the new measure is available. So the display of the message is triggered by the pin state change. Because Wave 1 pulse is 25ms and Wave 2 pulse is 10ms. We have more wave 2 pulse messages than wave 1 pulse messages.
