Introduction

Designing the monitoring and management program through the keyboard is an important part of the system design. For a complex electronic system, if a single defined key is used, a large number of keys are required, and the operation is not convenient, often using multiple defined keys. Commonly used keyboard management design methods include direct analysis method and state variable method.
