Introduction

This example demonstrates reading data from I2C based EEPROM devices present in the board. Application reads 20 samples from the EEPROM and exits.

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 freertos
	m4fss0-0 nortos
Toolchain	ti-arm-clang
Boards	xWRL6432-evm
Example folder	examples/drivers/i2c/i2c_read

Using SDK with SysConfig

A GUI tool SysConfig is used to configure different modules and peripherals of the example. Using this tool, users can select and customize different modules and peripherals. The SysConfig tool will generate the code for initializing and configuring these modules. This configuration is saved to a file called example.syscfg for every example.

Using SDK with SysConfig

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
