Using Keil MDK, I tried an example for STM32F107. After opening and compiling, the compilation succeeded, but the linker indicated that there were 5 functions undeclared. However, upon reviewing the files, it was clear that the header files were included. Why was it still not working? I also tried using extern declarations, but that did … Read more

Source: GF Securities With the development of intelligent connected vehicles, the number of onboard sensors is increasing, and the improving performance leads to a higher demand for computing power in onboard computing platforms. Compared to lower-level autonomous driving, advanced autonomous driving systems significantly increase the amount of data obtained from sensors, and the effective operation … Read more
Today we will learn what a BSP engineer is. 1. Embedded Systems To understand what an embedded software engineer is, we must first discuss embedded systems (embedded devices). The definition of embedded systems on Wikipedia is as follows: An embedded system (<span>Embedded System</span>) is a computer system that is embedded within mechanical or electrical systems, … Read more
0 Introduction Assembly language is a low-level programming language related to computer hardware. Since the Intel 80×86 processor and its compatible machines are the mainstream processors for personal computers, the current assembly language teaching in domestic universities mainly focuses on Intel processors and their development tools. Due to national information security considerations, establishing an independent … Read more
Click the blue text above to follow for continuous updates!!! Introduction Today, we will also not involve the Zigbee protocol, focusing solely on serial operations in the CC2530 microcontroller. This article uses Serial Port 0 for data transmission. The main function is to send serial data from a PC’s serial debugging tool to the microcontroller, … Read more
Introduction From this article, we officially step into the Zigbee protocol. This article will start with the basic Zigbee protocol, without using any packaged protocol stack. The content is migrated from a basic protocol template to the project, and has been updated to the code repository. Repository address: https://gitee.com/jeady5/zigbee-emaple Based on today’s project, I will … Read more

It focuses on the networking methods of ZigBee, the implementation of automatic control between nodes, and data collection and transmission. 1 Overview and Characteristics of ZigBee Technology 1.1 Overview … Read more
Recently, a friend of mine needed to create a DEMO related to image recognition. This friend, who holds a PhD, developed a fire alarm detection device. As we all know, our residential community has a surveillance system that allows us to see video images from various corners of the area. Based on this, my friend … Read more
The LCD screen is JM12864 or FYD12864 (with font library). I have used both models without issues. 4 rows * 8 columns of Chinese characters = 32 serial communication interfaces P1.5–P1.7, which can be modified according to your circuit. #include #define uchar unsigned char void LCD_ini(); void ascii_change(void); void delay(); void wri_add(uchar com); void wri_dat(uchar … Read more
