Electronic, 3D printing and embedded programming
In this article, we will dive into some technical details of the Ebyte LoRa E32 module integrated with the STM32 microcontroller. One key feature that we will explore is the WOR (Wake on Radio), which is a significant factor in the world of low-power long-range communication systems.
Microcontrollers, the core of many embedded systems, have evolved from being programmed with low-level languages like Assembly or C to more accessible high-level languages like Python. MicroPython, a streamlined Python 3 implementation, is a prime example. This article explores the integration of MicroPython with the cost-effective, high-potential STM32F4 microcontroller from STMicroelectronics, with a focus on the WeAct STM32F411CE, STM32F401CC, and Nucleo board.
Here an article that provides a step-by-step guide for getting started with MicroPython development on the ESP8266 and ESP32 boards using the Thonny IDE. The article covers how to flash MicroPython firmware onto the board and how to connect to the board using Thonny’s MicroPython plugin. Additionally, the article includes an example project that demonstrates how to control an LED connected to the board using MicroPython code.
This guide focuses on using MicroPython with ESP8266 and ESP32 microcontrollers, two popular choices for IoT and embedded systems. By understanding the standard instruments available with MicroPython, such as Python, esptool, ampy, PuTTY, and screen, you can quickly and easily build projects for these powerful devices. This guide will provide an overview of each tool and how to use them effectively, so you can take full advantage of the capabilities of your ESP8266 or ESP32 microcontroller.
It’s time to explore the new series of microcontrollers based on the rp2040 chip from the Raspberry Pi Foundation. As usual, we are going to use a generic Arduino IDE and C language.
After carrying out all the calibrations, all that remains is milling our piece. If the whole process is successful, I expect an excellent final product.
One of the most important features is the auto-level. Even if your CNC is precise, it will never be accurate to one-hundredth of a millimeter, but to carry out the removal of copper, you will have to have an excellent level of precision.
Here we are going to learn how to do auto-level.
I have been prototyping PCBs with the CNC for years. I have created a CNC machine suitable for this, and today I would not know how to do it without it.
I have been using bCNC for some time as a GCode sender, a very simple open-source software, we will see how to install it and do the probe.
The ESP32 has enough resources to be able to use a FAT system which is certainly more expensive in terms of resources, but which offers large dimensions and few limitations, as well as compatibility with various devices.
LittleFS was recently added and focuses on higher performance and directory support, but has a higher resource consumption and occupancy per file, although not by default for esp32 it should be remembered that it takes up less resources than FatFS.
