Design and Implementation of an Independent Keyboard Simulation System Based on Microcontroller

1. Control Requirements1.Keyboard Structure: An independent keyboard structure is adopted, consisting of 4 mechanical keys K0~K3;2.Debounce Algorithm: A software delay debounce algorithm is used to effectively eliminate interference caused by mechanical key bounce;3.Display Method: A static display using a digital tube is employed to clearly and real-time show the value of the pressed key.2.
