In this lab we will build a decoder circuit that can drive a common anode 7-segment LED display using a combinational logic circuit. The logic circuit is designed with four inputs and seven outputs. The four inputs will be connected to the switches on the Basys 3 development board, while the seven outputs will be connected to one of the four common anode 7-segment LED displays on the development board. Using Karnough’s map, logic circuitry for each input to the display will be designed. Figure1 shows a common anode 7-segment LED display and the pinout of the Basys 3 development board.
