Introduction

This example configures a GPIO pin connected to an LED on the EVM in output mode. The application toggles the LED on/off for 10 seconds 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/gpio/gpio_led_blink/

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
• Watch out for USER_LED on the EVM to blink which is controlled by GPIO_5 (J10).
