Display

Some ESP32 boards are available that combine display, touch screen and processor for implementing panels.

The Display example shows how to implement devices that take advantage of the touch screens and has some additional elements implemented especially for this scenario.

As the final sketch file will exceed the memory available in ESP8266 and ESP32C3 processors they should be avoided. The size of the sketch can be reduced by disabling elements that are not used for a specific board.

Display Output Elements

Analog Clock

The Analog Clock Element implementation can be found in the src sub-folder of the sketch. When configured it will draw an analog clock at the specified location on the screen in the specified colors.

For more information on the supported configuration properties see [AnalogClock Element].
