# 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.
