CS_LCD, A C# Library for LCD Displays (HD44780 Compatible) via I2C

Usage

To use the library just reference the CS_LCD.dll in your project or, since the full source code is provided, include the CS_LCD project in your C# solution.

The CS_LCD Library Calls

The following calls are publicly available in the CS_LCD library.
