Crate super_simple_st7789driver

super_simple_st7789driver

A simple async Rust driver for the ST7789 TFT display, based on embedded-hal traits.

Features

• Async SPI communication
• Basic display initialization
• Set row/column address
• Write memory and data

Example

use st7789driver::{St7789, Timer_};
use embedded_hal::digital::OutputPin;
use embedded_hal_async::spi::SpiBus;

struct MyTimer;
impl Timer_ for MyTimer {
    fn delay_ms(&self, ms: u64) -> impl core::future::Future<Output = ()> {
        async move {
            // Implement your async delay here
        }
    }
}

// Assume you have implementations for spi, cs, and dc
let mut lcd = St7789::new(spi, cs, dc, MyTimer);

// Initialization and basic operations
lcd.init().await.unwrap();
lcd.set_row(0, 319).await.unwrap();
lcd.set_col(0, 239).await.unwrap();
lcd.write_memory().await.unwrap();// send write data command
lcd.write_data(&[0x00]).await.unwrap();// send real data
