SH1106 driver
I2C driver for the SH1106 OLED display written in 100% Rust
Documentation
[Examples]
This crate uses probe-run
to run the examples. Once set up,
it should be as simple as cargo run --example <example name> --release
. --release
will be
required for some examples to reduce FLASH usage.
