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

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Boards	am263x-cc, am263x-lp
Example folder	examples/drivers/i2c/i2c_led_blink

AM263X-CC

• Watch out for LEDs LD2, LD3, LD4, LD5, LD6, LD7, LD8, LD9, LD10, LD11 on the CC to blink which is controlled by I2C2.

AM263X-LP

• Watch out for LED D7, D8, D9, D10, D11, D12, D13, D14 on the LP 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
