This larger sample mirrors the screen (or parts of it) from Windows or Linux onto an external, small display. The sample is configured to talk to an M5Though IoT module, a readily available integrated piece of hardware from M5Stack. The device features a QVGA display with touchscreen, a power distribution unit connected to an ESP32 microcontroller.

To run the sample, load the ConfigurableFirmata Firmware (V3.0 or later) onto the ESP32 first. The tool has some command line options:

Ft4222 Connect to the screen using an FT4222 instead of an Arduino/ESP32.
INET   Connect using a network connection instead of serial (recommended, as it is faster). Provide the IP address as additional argument
--nmeaserver If an NMEA server is also available, the display can show some information from an NMEA stream (e.g. speed)

And this then looks as follows:
