//! Draw a 1 bit per pixel black and white image.
//!
//! Wiring connections are as follows for a CRIUS-branded display:
//!
//! 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 embassy --features=embassy-stm32 --features=spi --release`.
//! or
//! Run with: `cargo run --example embassy --features=embassy-stm32 --features=i2c --release`.
//!
