Great excitement in the Botanical Garden of the University of Vienna. After three years the Amorphophallus titanum blooms for the first time in Vienna. Of course I had to see this rare event on the spot.

The Raspberry Pi is now largely obsolete for me. It has become too expensive and completely oversized for many tasks anyway. Now the new generation of the Zyklochron is ready. Besides the microcontroller, some other things have also changed.

How can a headless device be connected to a WLAN network? One possibility is SmartConfig, which makes provisioning very easy via smartphone. With this library for the ESP32, you only need a few lines of code to connect the device to the network.

The TMC2208 stepper motor driver from Trinamic is considered the reference as far as noise is concerned. Therefore I have developed a component for the ESP32, with which the TMC2208 can be controlled very easily via the UART interface.

The Raspberry Pi is getting more and more expensive and is poorly available. But what alternatives are there? I have decided to use the ESP32 as a new platform for my IoT projects. You can read about the reasons in this article.

Logging is one of the most important tools in software development. The Espressif IoT Development Framework offers a library for this purpose that logs to the UART interface by default. A setting allows the logs to be displayed in color.

With this component you can use the ESP32 microcontroller to find the time zone based on GPS coordinates. The required offline database is generated by a Java program and then stored on a flash chip.

Real hardware debugging with the ESP32 requires a JTAG debugger. This means that two USB ports are used on the PC. But it also works with only one USB connection.

The Raspberry PI does not have a battery-backed clock. Without a network, you therefore have neither the current time nor the current date. With a NEO-6M GPS module and a Python script, however, you can also get the time via the navigation system.

The Logitech Media Server, formerly also called Squeezebox Server, is the heart of the Squeezebox ecosystem. In this tutorial I describe the installation on a Raspberry 3B+ including a small display.
