Using PIC 16f819 and an LCD screen, code a game of tetris in C language that will use the PIC and four buttons to play tetris on the LCD.
The game should use the clock/timer fuction of the PIC- such as to time the length of each game and the eeprom function- to record th eplyaers high scores, as well as three levels of difficulty/speeds.
You are given the code to set up the LCD and the eeprom code.
