# 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](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32s2/esp32-s2-touch-devkit-1/user_guide.html)
|
|
|
|
### 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.
