Hello everyone, I am Da Yi, and today we are going to talk about the serial communication protocol between microcontrollers (MCU) and PLCs. When it comes to serial communication, many of you might feel confused, but don’t worry, I will clarify everything shortly. What is Serial Communication?Communication is everywhere; for example, the way you and … Read more
When it comes to flashing firmware, everyone is familiar with it. The essence of flashing is to update all or part of the programs in the chip and external memory of embedded products. Based on the various methods of programming chips involved from PCB production to R&D debugging, assembly, and finally to the user, today … Read more
Abstract Chip programming is an important part of the production process of electronic products, and the efficiency of programming is a key concern for customers. The efficiency of programming is closely related to the programming speed of the chip. What factors influence the programming speed of chips? 1. Different Manufacturers’ Chips The differences between chip … Read more
Author:Jens Wallmann Abstract:This article introduces the ultra-low power STM32WBA52 MCU series from STMicroelectronics, demonstrating how developers can quickly complete and run BLE 5.3 wireless designs using BLE evaluation boards, development tools, and application examples. Additionally, this article briefly discusses programming and MCU wiring. Intense competition puts pressure on Internet of Things (IoT) device developers, who … Read more
The intense competition has put pressure on IoT (IoT) device developers, who must quickly launch new innovative products while also reducing costs, ensuring stable, low-power, and secure communication. Traditional smart IoT terminal nodes include microcontroller units (MCU) for edge processing and wireless integrated circuits for connectivity. Problems arise when design teams lack the RF(RF) skills … Read more

GUI: Graphical User Interface. In the past, due to the limited resources and processing capabilities of MCUs, there were very few general GUIs based on MCUs. Now, with increased resources and stronger processing capabilities of MCUs, along with growing market demand, GUI functionalities have become richer. Let’s take a look at some common MCU-based GUIs. … Read more
1 Introduction to nr_micro_shell During debugging and maintenance, it is often necessary to interact with microcontrollers to retrieve or set certain parameters or execute specific operations. nr_micro_shell is a basic command line tool designed to meet this need for resource-constrained MCUs. Although the finsh command line interaction tool provided in the RT_Thread component is powerful, … Read more
We have all heard of static libraries and dynamic libraries. Static libraries are quite familiar to everyone, especially in microcontroller development. Dynamic libraries, however, are rarely seen in the microcontroller field. Today, I would like to share a method for dynamically loading functions, which is somewhat similar to dynamic libraries. Project Address: printf("hello world!"); Introduction … Read more
Development boards are circuit boards used for embedded system development, including a series of hardware components such as central processing units, memory, input devices, output devices, data pathways/buses, and external resource interfaces. When it comes to development boards, we have to mention the king of cost-performance ratio MCU—the ESP32 development board. 1. Powerful Functions The … Read more
