# Touch button example
|
||||
|
||||
This example demonstrates how to use the Touch Element library of capacitive touch sensor and set up touch button.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Configure the project
|
||||
|
||||
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `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.
|
||||

||||

# Touch Element waterproof Example
|
||||
|
||||
This example demonstrates how to use the Touch Element library of capacitive Touch Sensor and setup the touch elements with touch element waterproof protection.
|
||||
|
||||
## How to use 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.
|
||||
|
||||
## Example Output
|
||||
|
||||
This example's output maybe could not give a strong feeling to user since the waterproof function works
|
||||
automatically and silently inside the Touch Element library

# Touch button example
|
||||
|
||||
This example demonstrates how to use the Touch Element library of capacitive touch sensor and set up more than one type of touch elements and handle all the event messages in one task.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Configure the project
|
||||
|
||||
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `esp32s2`).
|
||||
|
||||
### 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.
|
||||
|
||||

# 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.
|
||||

||||

# Touch Element basic example (EVENT)
|
||||
|
||||
This example demonstrates how to use the Touch Element library of capacitive touch sensor and set up touch slider.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Configure the project
|
||||
|
||||
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `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.
|
||||

||||
