edrv-st7735

Rust driver for ST7735.

Overview

The ST7735 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 396 source line and 162 gate line driving circuits.

Maintenance

This project is maintained by the embedded-drivers team. Our organization's goal is to provide consistent driver access interfaces for embedded Rust and to maintain these drivers collectively to avoid orphaned crates.

Features

• Display driver using SPI
• Display driver using async SPI

Usage

use embassy_sync::blocking_mutex::raw::NoopRawMutex;
use embassy_sync::mutex::Mutex;

let spi = hpm_hal::spi::Spi::new_txonly(r.spi1, r.sclk, r.mosi, r.dma_ch0, config);

let spi_bus = Mutex::<NoopRawMutex, _>::new(spi);
let spi_dev = embassy_embedded_hal::shared_bus::asynch::spi::SpiDevice::new(&spi_bus, cs);
let mut display: ST7735<Display160x80Type2, _, _> = ST7735::new(spi_dev, dc);

let mut fb = Framebuffer::<
    Rgb565,
    _,
    BigEndian,
    160,
    80,
    { embedded_graphics::framebuffer::buffer_size::<Rgb565>(160, 80) },
>::new();

display.init(&mut Delay).await;

Or using blocking SPI:

use embedded_hal_bus::spi::AtomicDevice;
use embedded_hal_bus::util::AtomicCell;

let spi = hal::spi::Spi::new_blocking_txonly(r.spi1, r.sclk, r.mosi, config);
let spi_bus = AtomicCell::new(spi);

let spi_dev = AtomicDevice::new(&spi_bus, cs, Delay).unwrap();
let mut display: ST7735<Display160x80Type2, _, _> = ST7735::new(spi_dev, dc);
