Supported Targets	ESP32-S2

Touch Element basic example (EVENT)

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

How to use example

Configure the project

• Set the target of the build (where {IDF_TARGET} stands for the target chip such as esp32 or esp32s2).
• Run menuconfig to select a dispatch method for the example.

Build and Flash

Build the project and flash it to the target 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.
