Introduction

This example configures multiple GPIO pins connected to LEDs on the EVM in output mode. The application toggles the each LED on/off for 10 seconds and exits.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am243x-lp
Example folder	examples/drivers/gpio/gpio_multi_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 LED LD1 on the LP to blink which is controlled by GPIO0_22.
• Watch out for LED LD5 on the LP to blink which is controlled by GPIO0_26.
• Watch out for LED LD4 on the LP to blink which is controlled by GPIO0_27.
• Watch out for LED LD3(RED) on the LP to blink which is controlled by GPIO1_38.
• Watch out for LED LD3(GREEN) on the LP to blink which is controlled by GPIO1_39.
• Watch out for LED LD2 on the LP to blink which is controlled by GPIO1_55.
