TM1639

A platform agnostic driver to a LED-display powered by the TM1637 chip

What works

• Displaying raw bits and HEX-digits
• Controlling brightness

TODO

Example

Here is a simple example for using the MAX7219 on a stm32f103xx device with stm32f103xx_hal: ```rust

![deny(unsafe_code)]

![no_std]

extern crate cortexm; extern crate stm32f103xxhal as hal;

use hal::delay::Delay; use hal::prelude::*; use hal::stm32f103xx::Peripherals;

extern crate tm1637; use tm1637::{TM1637};

fn main() {

let dp = Peripherals::take().unwrap();

let mut rcc = dp.RCC.constrain();

let mut gpiob = dp.GPIOB.split(&mut rcc.apb2);

let mut clk = gpiob.pb6.into_open_drain_output(&mut gpiob.crl);
let mut dio = gpiob.pb7.into_open_drain_output(&mut gpiob.crl);

let mut flash = dp.FLASH.constrain();
let clocks = rcc.cfgr.freeze(&mut flash.acr);
let cp = cortex_m::Peripherals::take().unwrap();
let mut delay = Delay::new(cp.SYST, clocks);

let mut tm = TM1637::new(&mut clk, &mut dio, &mut delay);
tm.init().unwrap();
tm.clear().unwrap();
loop {
    for i in 0..255 {
        tm.print_hex(0, &[i, i + 1]).unwrap();

        tm.print_raw(3, &[i]).unwrap();

        tm.set_brightness(i >> 5).unwrap();
    }
}

} ```
