SSD1315

SSD1315 driver.

Usage

Here is an example of how to use ssd1315:

use ssd1315::*;
use embedded_graphics::{
    pixelcolor::BinaryColor,
    prelude::*,
    primitives::{Circle, PrimitiveStyle},
};

let interface = interface::I2cDisplayInterface::new(i2c);
// let interface = interface::SpiDisplayInterface::new(spi, dc);

let mut display = Ssd1315::new(interface);

Circle::new(Point::new(0, 0), 40)
        .into_styled(PrimitiveStyle::with_fill(BinaryColor::On))
        .draw(&mut display)
        .unwrap();

display.init(Default::default()).unwrap();
display.flush().unwrap();

Congratulations! Now you can see a small circle displayed on your OLED screen!

If you want to apply your own configuration for the SSD1315 (for example, to change the contrast), follow this example:

use ssd1315::*;
use embedded_graphics::{
    pixelcolor::BinaryColor,
    prelude::*,
    primitives::{Circle, PrimitiveStyle},
};

let interface = interface::I2cDisplayInterface::new(i2c);
// let interface = interface::SpiDisplayInterface::new(spi, dc);

let mut config = config::Ssd1315Config::new();
config.contrast = 0xff;

let mut display = Ssd1315::new(interface);

Circle::new(Point::new(0, 0), 40)
        .into_styled(PrimitiveStyle::with_fill(BinaryColor::On))
        .draw(&mut display)
        .unwrap();

display.init(config).unwrap();
display.flush().unwrap();

Alternatively, you can use a preset configuration provided by ssd1315:

let config = config::Ssd1315Config::preset_config();

Now you can see the change in contrast!

You might also want to draw some raw image(s) manually to fit your specific requirements. That’s no problem! You can draw it/them in an easy way:

let mut display = Ssd1315::new(interface);

let raw_image = [[0b1010_1010; 128]; 8];
*display.buffer_mut() = raw_image;

display.init(Default::default()).unwrap();
display.flush().unwrap();
