#ifdef UBITX_DISPLAY_LCD1602I
/**
* The Raduino board is the size of a standard 16x2 LCD panel. It has three connectors:
*
* First, is an 8 pin connector that provides +5v, GND and six analog input pins that can also be
* configured to be used as digital input or output pins. These are referred to as A0,A1,A2,
* A3,A6 and A7 pins. The A4 and A5 pins are missing from this connector as they are used to
* talk to the Si5351 over I2C protocol.
*
* Second is a 16 pin LCD connector. This connector is meant specifically for the standard 16x2
* LCD display in 4 bit mode. The 4 bit mode requires 4 data lines and two control lines to work:
* Lines used are : RESET, ENABLE, D4, D5, D6, D7
* We include the library and declare the configuration of the LCD panel too
