In this little game the player guesses a 8-bit unsigned number by setting a binary number on digital input port 'ui_in'. The player can manually follow the 'successive approximation' algorithm like its implemented in SAR ADCs to find the value. A 7-segment LED connected to 'uo_out' tells the player if his provided value is above, below or matching the wanted number.
Put the 'reset' port low (press the reset button on the demo board) and hold it for about a second in order to generate a secret number. Then set the DIP switches of the demo board in order to input a 8-bit value to the 'ui-in' port. The 7-segment LED will give immediate feedback if the player's number is above, below or exactly machting the 'secret' number. The player can continuously adjust the DIP switches until the wanted number is found.
To play another game just press the reset button again.
This game utilizes the DIP switch and the 7-segment LED of the demo board.
