//! Embassy I2C

//!
|
|
//! Depending on your target and the board you are using you have to change the
|
|
//! pins.
|
|
//!
|
|
//! This is an example of running the embassy executor with IC2. It uses an
|
|
//! LIS3DH to get accelerometer data.
|
|
//!
|
|
//! Following pins are used:
|
|
//! - SDA => GPIO4
|
|
//! - SCL => GPIO5
