Raspberry Pi Pico W - an alternative to the ESP32
Jul 4, 2022, 11:31 PM
Microcontrollers with built-in Wi-Fi are still rare. Now the Raspberry Pi Foundation has introduced the Raspberry Pi Pico W, which addresses exactly this weakness. This makes the Raspberry Pi Pico W an interesting alternative to the ESP32.

ESP32 instead of Raspberry Pi for the controlling of the Zyklochron
May 22, 2022, 1:52 PM
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.

ESP32 library for Trinamic TMC2208 stepper motor driver
Apr 19, 2022, 8:31 PM
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.

Goodbye Raspberry Pi - Hello ESP32
Mar 31, 2022, 12:14 PM
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.

Colored Logs with ESP32 and PlatformIO
Mar 8, 2022, 9:42 AM
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.

ESP32 library for offline time zone search with given GPS coordinates
Jan 27, 2022, 3:30 PM
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.

ESP32 JTAG debugging with PlatformIO and only one USB connection
Jan 19, 2022, 11:02 PM
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.
