First, set everything up.
- Install VS Code
- Install Extensions: Rust Analyzer, Even Better TOML
Run some commands:
- cargo install espup
- espup install
- C:/Users/YourUsername/export-esp.ps1
Note: The esp installer may say you don't need to set these environment variables. However this is often WRONG!
Here is code to blink the onboard LED of the ESP32-WROVER-DEV board!
#![no_std]
#![no_main]
use esp_backtrace as _;
use esp_hal::{clock::ClockControl, IO, peripherals::Peripherals, prelude::*, Delay};
use esp_println::println;
#[entry]
fn main() -> ! {
let peripherals = Peripherals::take();
let system = peripherals.SYSTEM.split();
let clocks = ClockControl::max(system.clock_control).freeze();
let mut delay = Delay::new(&clocks);
// let io = peripherals.IO.split();
// let io = peripherals.GPIO.p
let io = IO::new(peripherals.GPIO, peripherals.IO_MUX);
let mut led = io.pins.gpio2.into_push_pull_output();
println!("Hello world!");
loop {
println!("Loop...");
delay.delay_ms(500u32);
led.set_high().unwrap(); // Turn the LED on
delay.delay_ms(500u32); // Wait for 500 milliseconds
led.set_low().unwrap(); // Turn the LED off
delay.delay_ms(500u32); // Wait for 500 milliseconds
}
}
