ST / Mbed OS DISCO_L475VG_IOT01-Sensors-BSP

Read board sensors (temperature, humidity, pressure, gyroscope, accelerometer, magnetometer) using ST BSP drivers. This example is superceded with the HelloWorld_ST_Sensors example.

Dependencies:   BSP_B-L475E-IOT01

Information

This example is superceded with the HelloWorld_ST_Sensors example.

Import programHelloWorld_ST_Sensors

Simple application to test ST motion and environmental MEMS sensors. Supports NUCLEO+X-NUCLEO-IKS01A2 , STEVAL-STLKT01V1 (a.k.a. SensorTile) and B-L475E-IOT01A boards.
