SSD1315

The SSD1315 device driver serves for both SSD1315 and SSD1306. Supports both I2C and SPI interface.

Usage

Here is an example of how to use ssd1315:

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

// let i2c = ...; // Initialize your I2C peripheral here
let interface = interface::I2cDisplayInterface::new_interface(i2c);
// let interface = interface::SpiDisplayInterface::new_interface(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_screen();
display.flush_screen();

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

If you want to apply your own configuration to the SSD1315 (e.g. changing the contrast), follow this example:

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

// let i2c = ...; // Initialize your I2C peripheral here
let interface = interface::I2cDisplayInterface::new_interface(i2c);
// let interface = interface::SpiDisplayInterface::new_interface(spi, dc);

let mut config = config::Ssd1315DisplayConfig::default();
config.contrast = 0xff;

let mut display = Ssd1315::new(interface);
display.set_custom_config(config);

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

display.init_screen();
display.flush_screen();

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

use ssd1315::config;

let config = config::Ssd1315DisplayConfig::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. No problem! ssd1315 fits your need! You can draw it/them in an easy way:

// let interface = ...; // Initialize your I2C or SPI interface here
let mut display = Ssd1315::new(interface);

let raw_image = [[0b1010_1010; 128]; 8];
raw_image.draw_from_raw(&mut display);

display.init_screen();
display.flush_screen();
