Blinkt is a Rust library that provides an interface for the Pimoroni Blinkt!, and any similar APA102 or SK9822 strips or boards, on a Raspberry Pi.
Blinkt accesses the BCM283x GPIO peripheral either through /dev/gpiomem (preferred) or /dev/mem. Both the original APA102 and the SK9822 clone are supported. The APA102 RGB LED/driver ICs are referred to as pixels throughout the code and documentation.
All documentation can be found at doc.golemparts.com/blinkt.
Add a dependency for blinkt to your Cargo.toml.

extern crate blinkt;Call Blinkt::new() to create a new Blinkt with the default settings. In production code, you'll want to parse the result rather than unwrap it.
