Embedded Interface – LCD HD44780

• HD44780 compliant controllers 16×2 Character LCD is a very basic and low-cost LCD module that is commonly used in electronic products and projects.
• 16×2 means it contains 2 rows that can display 16 characters.
• Its other variants such as 16×1 and 16×4 are also available in the market.
• In these displays, each character is displayed using 5×8 or 5×10 dot matrix.
