In a previous article, I introduced the basic knowledge of SPI, see <<SPI>>. This time, I will present a design of a wireless communication system based on the 51 microcontroller, focusing on how to achieve data transmission between the microcontroller and the wireless module through the SPI (Serial Peripheral Interface) protocol. The system uses the … Read more
In today’s world where embedded systems and IoT devices are prevalent, the 51 microcontroller, as the “mentor” for electronic engineers, still holds an important position in industrial control, smart home, and other fields.On this land of China, domestic 51 microcontroller manufacturers are also in fierce competition. So, who is the “king” of domestic 51 microcontrollers? … Read more
This article introduces a design scheme for a multi-machine communication system based on the 51 microcontroller. The system achieves data exchange between a master device and multiple slave devices through a serial communication interface (UART), supporting address recognition and data verification functions. The article elaborates on the system’s hardware design, software programming, and communication protocol … Read more
On December 19, Qualcomm seems to be accelerating its layout in the RISC-V field as the patent war with Arm erupts. According to The Register, at last week’s global RISC-V summit, Qualcomm’s product management director Manju Varma revealed that Qualcomm has already integrated RISC-V into its Snapdragon 865 SoC microcontroller since 2019, and has shipped … Read more

ECU (Electronic Control Unit) is the core component of the automotive electronic system, primarily used to receive sensor signals, process data, and control actuator actions. It contains various electronic components, which can be categorized into the following functional modules: 1. Core Processing Module Microcontroller (MCU) Function: The “brain” of the ECU, responsible for computation, logic … Read more
Issue:The compile button in Keil5 is not working and appears gray. Cause: 1. A code file was created without a project. 2. Without a project, the system cannot detect components and the microcontroller, so compilation is not possible, even if there is code. Solution: 1. Save the file and import it into a project. 2. … Read more
