sharp-memory-display

An Adafruit 2.7" SHARP Memory Display driver with [embedded_graphics] support.

This is based off Adafruit's libraries and doesnotcompete's Rust driver, but crucially without the bitvec dependency which does not play nice with ESP32.

For usage on other display sizes, you will need to adjust the WIDTH and HEIGHT constants in the file. Alternatively use version 0.1.0 which has the display size passed through as arguments. For simplicity, I just hard-coded them.

Usage

This is an example of usage with esp-idf-svc.

use sharp_memory_display::SharpMemDisplay;
let spi_driver = SpiDriver::new(
    peripherals.spi2,
    pins.gpio36,
    pins.gpio35,
    None,
    &DriverConfig::new()
).expect("failed to create SPI driver");

let spi_config = config::Config::new()
    .baudrate(1u32.MHz().into())
    .bit_order(BitOrder::LsbFirst);

let spi_device = SpiDeviceDriver::new(
    &spi_driver,
    None,
    &spi_config,
).expect("failed to create SPI device");

let cs_pin = PinDriver::output(pins.gpio13).expect("failed to create CS pin");
cs_pin.set_low().ok();

let mut display = SharpMemDisplay::new(spi_device, cs_pin);
display.clear();
