Introduction

This example demonstrates setting of multiple LED at the same time connected to the same I2C controller. The application will blink all the I2C controlled LED in the EVM.

Application blinks leds for 3 loops in interrupt mode and 3 loops in polling mode. Application exits after 6 iterations.

Supported Combinations

Attention

A53 NORTOS, A53 FREERTOS and A53 FREERTOS SMP support is experimental and is NOT supported by TI.

Parameter	Value
CPU + OS	r5fss0-0 nortos
	a53ss0-0 nortos
Toolchain	ti-arm-clang
	arm.gnu.aarch64-none
Board	am64x-evm, am64x-sk

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
