The TWILCD is an easy to use dot matrix character display controller (backpack) that is controlled using the TWI (I2C compatible) protocol.
It is super-easy to control with any microcontroller that supports the TWI/I2C protocol. Libraries for Arduino and avr-gcc are available on GitHub.
The library is compatible with the Arduino LiquidCrystal library, so any sketch you have that uses a standard dot matrix display (with the HD44780 controller) can be converted to use the TWILCD with only 4 wires with only one single line of code change.
Only four wires are required for operation, one for power (runs on both 3.3V and 5V), one for ground, and two for the TWI protocol.
This is the 40x2/40x4/RGB. It is suitable for displayws with 1x18 connector (for Newhaven RGB backlit displays), 2x8 connector (used for some 20x4 displays) and 2x9 connector (used for 40x4 displays)
40x4 displays are directly supported (not supported by the normal LiquidCrystal library).
