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 following calls are publicly available in the CS_LCD library.

The CS_LCD library source is based on, and largely ported from, the excellent python_lcd code of Dave Hylandshttps://github.com/dhylands/python_lcd
