//! Embassy "async" vesrion of ead calibration data from BMP180 sensor
|
|
//!
|
|
//! This example dumps the calibration data from a BMP180 sensor by reading by reading
|
|
//! with the direct I2C API and the embedded-hal-async I2C API.
|
|
//!
|
|
//! //! Folowing pins are used:
|
|
//! SDA GPIO4
|
|
//! SCL GPIO5
|
|
//!
|
|
//! Depending on your target and the board you are using you have to change the
|
|
//! pins.
|
