Frantisek Hrbata 1c92945f59 change(examples): switch examples to use a minimal build 
Currently, several example dependencies rely on the fact that all
registered components are added to the build, along with components
specified in common requirements. This results in longer build times
because even unused components must be built. Switch all examples to use
idf_minimal_build to compile only the components actually required by
the example.

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

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.
