max6955

A platform agnostic driver to interface with MAX6955 LED Display Driver

• MAX6955 datasheet

Example

```rust

[entry]

fn main() -> ! { let dp = stm32f30x::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 gpiob = dp.GPIOB.split(&mut rcc.ahb);
let scl = gpiob.pb6.into_af4(&mut gpiob.moder, &mut gpiob.afrl);
let sda = gpiob.pb7.into_af4(&mut gpiob.moder, &mut gpiob.afrl);

let i2c = I2c::i2c1(dp.I2C1, (scl, sda), 400.khz(), clocks, &mut rcc.apb1);

// create an instance with the default address 0x60
let mut max6955 = Max6955::new(i2c).unwrap();
// power up
max6955.powerup().unwrap();
// set intensity
max6955.set_global_intensity(4).unwrap();
// write text
max6955.write_str("HELLO").unwrap();

loop {}

} ```
