AW9523 Example

This example shows how to use the Aw9523 component to communicate (via I2C) with an AW9523 I2C digital IO expander and LED driver.

It is currently designed to run on an ESP32-S3, but (by changing the I2C pin definitions in the main file) can be reconfigured to run on any of the ESP32 chips.

How to use example

Hardware Required

This example requires a connection (via I2C) to a dev board which has an AW9523. To that chip should be attached some digial inputs (such as buttons) as well as an RGB LED.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
