I2C Temperature Read

Introduction

This example demonstrates probing of sensor via I2C and read data from it. The application reads data from the temperature sensor in the EVM. Application reads 20 samples from the sensor and exits.

Supported Combinations

Steps to Run the Example

  • When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).

  • When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)

Attention

As the wake-up R5 is the device manager, it needs to be started by the SBL. So it can not be loaded through CCS. It should be flashed and booted through SBL.
