-/* This is a hack of Simon Ford's direct-driven TextLCD code.
-* It should be refactored to extract a common superclass
-* but my C++ isn't yet good enough :) 
-*
-* The code assumes the following connections between the PCF8574
-* and the LCD
-* 
-* nc  - D0
-* nc  - D1
-* nc  - D2
-* nc  - D3
-* P0  - D4
-* P1  - D5
-* P2  - D6
-* P3  - D7
-* P4  - E
-* P5  - nc
-* P6  - nc
-* P7  - RS
-* gnd - R/W
-*
-* D0-3 of the LCD are not connected because we work in 4-bit mode
-* R/W is hardwired to gound, as we only ever write to the LCD
-* A0-2 on the PCF8574 can be set in any combination; you will need to modify
-* the I2C address in the I2CTextLCD constructor.
-* Remember that the mbed uses 8-bit addresses, which should be
-* in the range 0x40-0x4E for the PCF8574
