Introduction

This example demonstrates writing data to & reading data from the EEPROM connected to the I2C controller. Application writes 10 Bytes to the EEPROM in interrupt mode and then reads back the same 10 Bytes.

The application makes use of the I2C LLD driver and it's memory read/write polling APIs.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Boards	am263x-cc, am263x-lp
Example folder	examples/drivers/i2c/i2c_memory_read_polling_lld

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
