Being faster, gives your applications more time to do more things than just controlling the LCD. So, its cool, you can do more stuff. It supports most Hitachi HD4.

Library Overview. This library provides the same interface to applications as the Liquid. Crystal library sourced by the. Arduino SDK. The main changes to the Liquid. Crystal Library is that it has been changed to be a pure. All the basic functions to control an LCD are implemented in the base class, while the particular. LCD is done by a class that simply knows how to write to the LCD. Therefore, it is possible to create new drivers to the library by simply inhering from the base class. LCD. The library currently supports 3 types of connections 4 bit parallel LCD interface. LCD interface. I2. C IO bus expansion board with the PCF8. I2. C IO expander ASIC. Shift. Register adaptor board please visit the HW schematics and configuration for details. The LCD library started as a base support for the PCF8. I2. C IO expander ASIC in the. LCDI2. Cextra. IO board. LCD driving mechanism due to the simplicity of adding. Since this library is a full class hierarchy, new interfacing mechanisms can be added without having. Drivers for the MCP2. SPI and Serial are very easy to develop since. Usage. The library is used just like the current stock Liquid. Crystal LCD library. You only have to tell it. LCD and how you have connected to your project and you are set. The main difference is. LCD library is a collection of libraries with the same common interface a class.

Not a bit difference, right When you install the library it may come out with a compilation error. This is due to the fact that. Wire library header files. Please include Wire. Why Because of the peculiarities of the Arduino compilation environment. I am working on a way to work around this. The library is configured by default to run fast. Should you have problems with slow LCDs, you will. FASTMODE in the LCD. FASTMODE define. Tests. All the HW configurations described in the HW section have been tested, the last one was the Shift.
