Programming: Displaying Simple Characters to the LCD

The AVR microcontroller is programmed to show simple characters on the LCD (Liquid Crystal Display). The pin functions are defined so the microcontroller can easily access these pins with an understandable name. Four functions are created to make it easy to write typical methods that the LCD can understand. These functions are Peek_A_Boo (Gets the LCD to see the data), Send_A_ Command, Send_A_Character, and Check_IF_MrLCD_IsBusy. With these definitions and functions, the main function can then be written easily accessing these functions when needed to send a command and to send a character.
