Introduction

The General-Purpose Inputs and Output (GPIO) reference application demonstrates using GPIOs as inputs and outputs using buttons and Light Emitting Diodes (LEDs). One application supports waking up from sleep using a GPIO interrupt.

Hardware Setup

QPG6105 Smart Home and Lighting Carrier Board, GPIO

QPG6105 GPIO Configurations

GPIO Name Direction Connected To Comments
GPIO0 Input (Pull-up) SW1 Button (Controlling red LED)
GPIO22 Input (Pull-up) SW2 Button (Controlling red LED)
GPIO3 Input (Pull-up) SW3 Button (Controlling white (cool) LED)
GPIO5 Input (Pull-up) SW4 Button (Controlling white (warm) LED)

Usage

After loading the program to the board and running:

  • Pressing the SW1 button will turn on the red LED (LD4), releasing it will turn off the red LED (LD4).

  • Pressing the SW4 button will turn on the (warm) white LED (LD2), releasing it will turn off the (warm) white LED (LD2).

  • Pressing and releasing SW2 button will toggle the red LED (LD4).

  • Pressing and releasing SW3 button will toggle the (cool) white LED (LD1).
