PWM code is taking 'No such device' error.

[system-linux]

Using this library with my Raspberry Pi 5, I ran the ready-made example code below using sudo:
`Rust
use std::error::Error;
use std::thread;
use std::time::Duration;
use rppal::pwm::{Channel, Polarity, Pwm};

fn main() -> Result<(), Box> {
// Enable PWM channel 0 (BCM GPIO 18, physical pin 12) at 2 Hz with a 25% duty cycle.
let pwm = Pwm::with_frequency(Channel::Pwm0, 2.0, 0.25, Polarity::Normal, true)?;
// Sleep for 2 seconds while the LED blinks.
thread::sleep(Duration::from_secs(2));
// Reconfigure the PWM channel for an 8 Hz frequency, 50% duty cycle.
pwm.set_frequency(8.0, 0.5)?;
thread::sleep(Duration::from_secs(3));
Ok(())
}`

But this code does not work and gives the error Error: Io(Os { code: 19, kind: Uncategorized, message: "No such device" }).
Note: I ran the program with sudo due to an permission error.

Apologies for the late response. This type of error usually means PWM hasn't been properly configured. Make sure you have added dtoverlay=pwm to your /boot/firmware/config.txt (and reboot the Pi after).

@system-linux were you able to resolve this issue?

Closing this due to inactivity. If you're still encountering this error, and it's not a Raspberry Pi OS configuration issue, please let me know and we can revisit the matter.

I'm so sorry, I didn't have time to reply. I don't have time to try this anymore in my project because we decided to use C++ wiringPi. So I haven't had a chance to try it yet.
