Interface Guide: Controlling LCD1602 Character Displays on 8051 Microcontrollers
The LCD1602 is a character-oriented liquid crystal display capable of rendering two lines of 16 alphanumeric symbols per line. Its internal architecture divides each character cell into 5x7 or 5x10 vertical dot grids. Due to rigid spatial spacing and the absence of pixel-level control, complex graphical rendering is unsupported. Direct communic ...
