This crate provides a platform agnostic driver for the MAX7219 LED Driver IC.
This driver was built using the embedded-hal traits.
An updated version of the library should be available on crates.io. Add the following to your Cargo.toml to get is a dependency.
rust
[dependencies]
max7219-driver = "*"
Create an instance of the driver with the new method, by passing SPI and Output pin instances.
rust
use max7219-driver::MAX7219;
let spi = // SPI instantiation code
let cs = // Output pin instantiation code
let mut max7219 = MAX7219::new(spi, cs).unwrap();
Initialize the driver instance with the init_display method. A boolean needs to be specified to indicate whether to clear the display after init or not.
rust
max7219.init_display(true);
