Touch Element matrix example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example demonstrates how to use the Touch Element library of capacitive touch sensor and set up touch matrix.

How to use example

Hardware Required

A development board with ESP32-S2 or ESP32-S3 chip
A touch extension board like esp32-s2-touch-devkit-1

Configure the project

Set the target of the build by following command, where TARGET can be esp32s2 or esp32s3.

idf.py set-target TARGET

Run idf.py menuconfig to select a dispatch method for the example.

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.
