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 exits after 10 iterations..

Supported Combinations

Parameter	Value
CPU + OS	mcu-r5fss0-0 nortos
	wkup-r5fss0-0 freertos
Toolchain	ti-arm-clang
Boards	am62px-sk

AM62X-SK

• Watch out for LED LD2 to blink which is controlled by I2C1.

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

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.

• Refer Flash a Hello World example for flashing the application.
