This is a guide for cross-compiling Qt 5.15.2 for Raspberry Pi 4 and installing it on the Compute Module 4.
It's an update to my blog post Qt on the Raspberry Pi 4, with the difference that this time I'm using Raspberry Pi OS Lite.

In this blog, I would like to provide a small Qt Quick application (qml) as an example of a Modbus connection over TCP/IP.
In the Qt examples, I have only found QWidget examples for Modbus connections, and after recently creating a Qt Quick application for this, I would like to provide a slimmed-…

You can also use the USB-C interface of the Raspberry Pi 4, which is normally used for power supply, as a normal USB interface.
In this case, however, the Raspberry should supply power via the GPIO pins.

The goal was to write a Qt application for the Raspberry Pi 4 that can be used to switch between different WLAN access points and store the associated credentials.
I used a raspbian-buster-lite image and a Qt installation as described in Qt on the Raspberry Pi 4 as a starting point.
In addition, I…

The task was to write a Qt Quick application (GUI) to upload new firmware to a touch controller.
The upload software was provided by the manufacturer in a .exe application that loads a .bin file onto the touch controller.
I wanted to use the Qt classes "QProcess", which can be used to call and…

If you have created a Qt application - or any other application - for the Raspberry Pi 4, you often want the application to be called immediately after restarting the Raspberry after the application has been completed.
This is often attempted with start scripts that can be entered in various places…

Due to the frequent writing or overwriting of data, the lifespan of an SD card is affected.
For example, it is recommended to write temporary data (e.g. sensor values for comparative calculations) to a RAM disk for applications that often contain temporary data (e.g. sensor values for comparative…

Recently I had to develop an application (kiosk system) for/on a Raspberry Pi 4. The special thing about it was that 2 touch monitors were to be connected via HDMI, which had to be rotated 90 degrees to the right. So portrait formats, 2 monitors on top of each other.
Rotating the screen and…
