To: lcdproc at

For your consideration, I have attached a v0.5.6 patch which adds a driver
for the Adafruit PiPlate ( The PiPlate
includes a HD44780 LCD and 5 button keys which is accessed via a MCP23017
I2C IO expander.

The driver was adapted from the HD44780-i2c driver, which uses the PCF8574
I2C IO expander.
