SSD1315

The SSD1315 device driver serves for both SSD1315 and SSD1306.

Introduction

SSD1315 is a single-chip CMOS OLED/PLED driver with controller for organic/polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons. This IC is designed for Common Cathode type OLED/PLED panel.

Example

Here is a full example (the MCU model is STM32F411CEU6):

#![deny(unsafe_code)]
#![no_std]
#![no_main]

use cortex_m::asm::nop;
use cortex_m_rt::entry;
use embedded_graphics::{
    pixelcolor::BinaryColor,
    prelude::*,
    primitives::{Circle, PrimitiveStyle},
};
use panic_halt as _;
use ssd1315::*;
use stm32f4xx_hal::{
    i2c::{DutyCycle, Mode},
    pac,
    prelude::*,
};

#[entry]
fn main() -> ! {
    let dp = pac::Peripherals::take().unwrap();

    let rcc = dp.RCC.constrain();
    let clocks = rcc.cfgr.freeze();

    let gpiob = dp.GPIOB.split();
    let (scl, sda) = (
        gpiob.pb8.into_alternate_open_drain(),
        gpiob.pb9.into_alternate_open_drain(),
    );

    let i2c = dp.I2C1.i2c(
        (scl, sda),
        Mode::fast(400000.Hz(), DutyCycle::Ratio2to1),
        &clocks,
    );

    let interface = interface::I2cDisplayInterface::new_interface(i2c);
    let config = config::Ssd1315DisplayConfig::preset_config();

    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();

    loop {
        nop()
    }
}
