Write an Assembly coding file with the series of instruction in
this question.
Use the external 8-pin switches to determine a 2-digit
hexadecimal number and show each digit on the 7-segment
display.
***Note: The coding language is Assembly and the board is the
DE10-NANO:
Please use proper assembly language for the file.

LOOP: Load JP1/JP7; Load LED; Load LOOKUP Change Directions for JP1/JP7 while is used as output Load values from DIP switches (JP1/JP7) to register Use MASKS to obtain right 4 bits and left 4 bits LDR R2,=JP1_BASE LDR R5,=0xFFFFFFFF STR R5, [R2, #4] The same as Lab 2, left 4 bits need to be logic shifting Find the corresponding value of your LOOKUP for the first 7-segment, then load it to a register Do the same step for the second 7-segment Combine the first and second 8 bits together, and store it to the JP1/JP7 (as output) See next page Hint: LSL, ADD 0123456789 A62366
For instance, assume I get a 4-bit value which is R8 = 0b00001001, it is R8 = 9 in decimal. Suppose I have already loaded all LOOKUP into the register R4, so it may be stored from 0x0000000c as an example. What we need to transfer Ob00001001 (9) to the 7- segment display form which should be Ob01101111 (111 in decimal) and output this value to the JP7 which connect to the 7-segment displays. • Let's say: 0023456789 A62366 LOOPUP: .word Ob00111111, Ob00110000, 0b01101101, Ob01111001 // 0, 1, 2, 3 .word Ob01110010, 0b01011011, 0b01011111, Ob00110001 // 4, 5, 6, 7 Ob01111111, Ob01111011, Ob01110111, 0b01011110 // 8, 9, A, B Ob01001100, Ob01111100, Ob01001111, Ob01000111 // C, D, E, F .word 63, 6, 91, 79, 102, 109, 125, 7, 127, 111, 119, 124, 88, 94, 121, 113 //decimal So, in fact, we want to get the value of 111 from the LOOKUP. .word .word Number on 7-seg: 0 1 2 3 5 6 7 8 9 Memory address: 0x0000000c 0x00000010 0x00000014 0x00000018 0x00000010 0x00000020 0x00000024 0x00000028 0x0000002c 0x00000030 0x00000034.... 119...
