Examples

From examples/image_i2c.rs:

```rust

![no_std]

extern crate cortexm; extern crate embeddedgraphics; extern crate embeddedhal as hal; extern crate ssd1306; extern crate stm32f103xxhal as blue_pill;

use bluepill::i2c::{DutyCycle, I2c, Mode}; use bluepill::prelude::*; use embeddedgraphics::Drawing; use embeddedgraphics::image::{Image, Image1BPP}; use embedded_graphics::transform::Transform; use ssd1306::{Builder, mode::GraphicsMode};

fn main() { let dp = bluepill::stm32f103xx::Peripherals::take().unwrap(); let mut flash = dp.FLASH.constrain(); let mut rcc = dp.RCC.constrain(); let clocks = rcc.cfgr.freeze(&mut flash.acr); let mut afio = dp.AFIO.constrain(&mut rcc.apb2); let mut gpiob = dp.GPIOB.split(&mut rcc.apb2); let scl = gpiob.pb8.intoalternateopendrain(&mut gpiob.crh); let sda = gpiob.pb9.intoalternateopen_drain(&mut gpiob.crh);

let i2c = I2c::i2c1(
    dp.I2C1,
    (scl, sda),
    &mut afio.mapr,
    Mode::Fast {
        frequency: 400_000,
        duty_cycle: DutyCycle::Ratio1to1,
    },
    clocks,
    &mut rcc.apb1,
);

let mut disp: GraphicsMode<_> = Builder::new().connect_i2c(i2c).into();

disp.init().unwrap();
disp.flush().unwrap();

let im = Image1BPP::new(include_bytes!("./rust.raw"), 64, 64).translate((32, 0));

disp.draw(im.into_iter());

disp.flush().unwrap();

} ```
