Struct ssd1675::interface::Interface

pub struct Interface<SPI, CS, BUSY, DC, RESET> { /* fields omitted */ }

The hardware interface to a display.

Example

This example uses the Linux implementation of the embedded HAL traits to build a display interface. For a complete example see the Raspberry Pi Inky pHAT example.

extern crate linux_embedded_hal;
use linux_embedded_hal::spidev::{self, SpidevOptions};
use linux_embedded_hal::sysfs_gpio::Direction;
use linux_embedded_hal::Delay;
use linux_embedded_hal::{Pin, Spidev};

extern crate ssd1675;
use ssd1675::{Builder, Color, Dimensions, Display, GraphicDisplay, Rotation};

// Configure SPI
let mut spi = Spidev::open("/dev/spidev0.0").expect("SPI device");
let options = SpidevOptions::new()
    .bits_per_word(8)
    .max_speed_hz(4_000_000)
    .mode(spidev::SPI_MODE_0)
    .build();
spi.configure(&options).expect("SPI configuration");

// https://pinout.xyz/pinout/inky_phat
// Configure Digital I/O Pins
let cs = Pin::new(8); // BCM8
cs.export().expect("cs export");
while !cs.is_exported() {}
cs.set_direction(Direction::Out).expect("CS Direction");
cs.set_value(1).expect("CS Value set to 1");

let busy = Pin::new(17); // BCM17
busy.export().expect("busy export");
while !busy.is_exported() {}
busy.set_direction(Direction::In).expect("busy Direction");

let dc = Pin::new(22); // BCM22
dc.export().expect("dc export");
while !dc.is_exported() {}
dc.set_direction(Direction::Out).expect("dc Direction");
dc.set_value(1).expect("dc Value set to 1");

let reset = Pin::new(27); // BCM27
reset.export().expect("reset export");
while !reset.is_exported() {}
reset
    .set_direction(Direction::Out)
    .expect("reset Direction");
reset.set_value(1).expect("reset Value set to 1");

// Build the interface from the pins and SPI device
let controller = ssd1675::Interface::new(spi, cs, busy, dc, reset);
