oled_async 0.2.1

//! Print:
//!
//!  Hello world!
//!
//!     <<=== (R) ===>>  // Moving RUST logo
//!
//!  Hello rust!
//!
//! the text with a 6x8 pixel font.
//!
//! This example is tested with an STM32G431 board connected to a SH1107 based display via SPI or I2C.
//!
//! It should be easy to modify:
//!  - Display type: Choose below
//!  - Chip/board, if STM32:
//!       - Modify chip in Cargo.toml
//!       - Choose different periperals and pins in bsp.rs
//!
//! Run with: `cargo run --example image --features=embassy-stm32 --features=spi --release`.
//! or
//! Run with: `cargo run --example image --features=embassy-stm32 --features=i2c --release`.
//!
