Unformatted text preview: ECE 25 Lab 3 Seven Segment Display Introduction Goal: Design a circuit using Project Navigator that will control a seven segment display on the board. The pinout for each segment (a-g) is given on the Basys Reference Manual on the Lab Web site. We will use this display to make a hexidecimal counter driven by the 4-bit counter chip we have used in the last two Labs. For a hexadecimal counter, there are a total of 16 possible outputs, ranging from 0 -F as shown on the truth table below that must be mapped to the seven-segment display. . Value Output 0000 0 0001 1 0010 2 0011 3 0100 4 0101 5 0110 6 0111 7 1000 8 1001 9 1010 A 1011 b 1100 C 1101 d 1110 E 1111 F The letters A, C, E, and F will be capitalized. Letters b and d will be lower case. As an example, if the counter is in state “1101” then the segments b,c,d,e, and g are lit which forms a lower case “d”. As the 4-bit counter cycles through each state from 0000 to 1111, you should see the corresponding hex representation on the display. You need to determine the combinational logic for each of the seven segments (a-g) of the display. (a-g) of the display....
