My self-written libraries for HD47780-driven LCDs for PIC MPUs. All written from scratch.

Contents

The libraries include:

• 4-bit interface mode
• 8-bit interface mode
• 8-bit interface mode via i2c. (Coming Soon)

Features

• It's written for 8-bit MPUs but can be easily adapted to others (if required).
• Efficient implementations.
• All HD47780 instructions are fully implemented.
• The same library for all interface modes. 😄
• Basic display operations implemented.
• A bunch of error-checking.
• Easy-to-use interface.
• Relatable names of utilities.
• Unnecessary details hidden from main program.
• Custom Character Generation (coming soon).

Functionalities

• Single Character display
• Character String display
• Integer dislay
• Floating-point display
• Backspace
• Cursor movements
  • Up & Down
  • Left & Right (With option for number of positions)
  • Home & End (within same line)
  • Home (first line beginning)
  • Abitrary Positon
• Reverse Cursor Direction
• Display Shift/Scroll: Left & Right (With option for number of positions)
• Scroll animation with following parameters:
  • Number of repetitions
  • Start and End Positions
  • Scroll speed

NOTE: All operations are aware of display bounds and employ a number of input "error-checking" methods.
