Design of badminton scoring device based on 51 single chip microcomputer

1. Hardware Solution This design uses the AT89C51 microcontroller as the core component. This design consists of three parts: control system, display module, and key drive module. The main program, interrupt program, display program function module program, etc. are written to realize the badminton scorer function.

Design of badminton scoring device based on 51 single chip microcomputer

Single chip microcomputer controls LCD1602 to display characters (test passed)

This test is on the commonly used LCD1602 display screen. The operation process is very simple, but there are some minor issues to pay attention to. For example, the LCD processing speed is a bit slow, and the microcontroller needs to delay appropriately when sending control instructions, otherwise the operation may fa
