CharLCD_I2C Component interface for PCF8574AT / HD44780 Combo
The CharLCD_I2C component provides an interface with the PCF8574AT I2C PC Board connected to the Industry Standard HD44780 LCD Controller (running in 4-bit mode) using only 2 I/O pins, SDA and SCL pins. The CharLCD_I2C component requires an I2C Master component to provide the I/O. For the PSoC 4 use the I2C (SBC mode)[v3.2] Master Component. For the PSoC 3 and PSoC 5 use the I2C Master (Fixed Function)[v3.50] Component. The instance name of the I2C Master Component needs to be I2C_ 'instance name of the CharLCD_I2C component'. It has been tested and works with the PSoC 3, PSoC 4 and the PSoC 5 provided with the C8YC KIT-001.
