Daniel Lee / Mbed OS TextLCD_FC113

Initial setup for FC-113 controller of TextLCD(1602A)

Dependencies:   TextLCD

This example is a simple use case for the user of Text LCD with the FC-113 controller, based on Mbed OS 5.

Note that PCF8574T has Mbed base addresses 0x40 ~ 0x4E, while PCF8574AT has base addresses 0x70 ~ 0x7E.

I used 0x4E for Text LCD with the FC-113 controller.
