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

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am64x-evm, am64x-sk
Example folder	examples/drivers/i2c/i2c_temperature

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)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
