16X2 overview

A 16x2 LCD (Liquid Crystal Display) screen is an electronic display module used in various devices and circuits. A 16x2 LCD can display 16 characters per line with the characters stretched between 2 rows (i.e. lines). In a 16x2 LCD, each character is displayed in a 5x7 pixel matrix. The 16x2 intelligent alphanumeric dot matrix display is capable of displaying 224 different characters and symbols. This LCD has two registers, namely, Command and Data.

Command register stores various commands given to the LCD display. The data register stores data to be displayed on the LCD matrix. The process of controlling the display revolves around putting the data that form the image of what you want to display into the data registers, then putting instructions in the instruction register.
