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
An international research team led by Wake Forest University has made significant breakthroughs in the field of bioprinting: they have utilized a novel bioink to 3D print functional human islets, demonstrating enormous clinical application potential, bringing new hope for the treatment of Type 1 diabetes.
