Clear All Display Data on LCD Liquid Crystal Display
Introduction
The LCD Liquid Crystal Display (LCD) is a commonly utilized output device in embedded systems, serving to present text and numerical data to the end user. To effectively utilize the LCD, it is crucial to clear all existing display data, allowing for the refresh of data without any remnants of previous content.
