Design and Implementation of a Key Increment/Decrement Digital Tube Display System Based on AT89C52 Microcontroller
Abstract This article designs a key increment/decrement digital tube display system based on the AT89C52 microcontroller. The system achieves numerical increment and decrement control through independent keys and drives the digital tube display using a dynamic scanning method. The paper details the hardware circuit design, software programming implementation, and anti-interference measures of the system. Test … Read more
