When you start uP圜raft for the first time, you will probably be prompted to install SourceCodePro.

Copy it to the folder you want to work from. There is no installation file, but you get the executable program directly as an “.exe” file. If you are using Windows, you can download uP圜raft here. Installing uP圜raft and setting up the ESP32 Installation Run the installation file, and choose “Add Python version to PATH”.For Windows, the best option is “Windows installer (64-bit)”. In the Files section (scroll down a bit on the page), you select the correct installation file.On you will find the download link for the latest version.You have to install Python first, because MicroPython is based on it. On you will find the excellently structured documentation for MicroPython. MicroPython is available for the ESP32 and the ESP8266 among others. Since the programs you create always require the MicroPython interpreter, this language is only suitable for microcontrollers with correspondingly large memory and sufficient computing power. You could say that in terms of Python, MicroPython is what the “Arduino language” is for C++, namely an adaptation for microcontrollers.

Syntax errors are detected only when the interpreter encounters the corresponding line. In addition, it is more difficult to find bugs. Among hobby electronics engineers, Python has spread mainly through its use on the Raspberry Pi.īut Python also has disadvantages: the programs are interpreted and not compiled. He is apparently a Monty Python fan because that’s where the name comes from. The language is quite young – it was developed in the early 90s by Guido van Rossum. Python code is easy to read and very compact.

Python is an object-oriented high-level language that is comparatively easy to learn. Here you can find more information on the ESP32. Helpful, but not absolutely necessary, is previous experience with the ESP32. But only by practicing can you learn the language. So try things out and vary the examples, although many things may be boring at first. In programming books, this would fill dozens of pages. It’s a lot of knowledge in a small space that I’m trying to impart here. In the next post I will show you how to use other functions of the ESP32 like PWM, A/D converter, timer, etc. In addition, you will be able to control the ESP32’s GPIOs with the counterparts of digitalWrite() and digitalRead().

Appendix: Installing Thonny as an alternative to uP圜raftīy the end of working through this post, you will be able to write simple MicroPython programs.

Simple GPIO operations with MicroPython.

For this purpose, I use the ESP32 as a microcontroller and uP圜raft as a MicroPython IDE. This article is aimed at those who have experience in programming Arduino boards, but want to take a look beyond the horizon with MicroPython.
