Question

University nology LEARNING OUTCOME 3 A learner is expected build a simple circuit that uses a PIC16F627A micro-controller to decode binary numbers to BCD counter that will display a zero to 9. Make sure that you download the data sheet for the type of 7 segment you have. The circuit must be able to convert the binary numbers from the four switches to a BCD that is to be displayed on a 7 segment display Buld a dirout that wil accomplish what is described above. Ifal four SWITOESS are open, the croît should display a o, and if the SWITCH! s pressed, the cirouit display a 1, etc NOTE There must be no noticeable delay between pressing or releasing the switch and the counter changing direction Hint: LOOKUP TABLE DO NOT USE A LOOKUP TABLE DOCUMENTATION OF RESULTS 1. A cover page as descrbed in Experiment 1 2. A fully labelled block diagram of the circuit 3. Component list as described in Experiment 1 4. A fully labelled crcut diagram as described in Experiment 5. The function of each component in this dircuit . A flowchart 7. Fully commented program listing. 8. A desaription of your understanding of the operation of the orcuit 1.Build a circuit using PIC16F627A microcontroller that will decode binary number to BCD counter that will display zero to 9 2.Draw a fully labelled block diagram of that circuit builded 3.Name the components used to build a circuit 4.write the function of each components used to connect the circuit 5.Draw a control flow chart s 6.Write a program code pic16f627a

don't make use of truth table or logical operation

Answer 1

LDI R1, 0x00 ; Load immediate value in register R1
MOV DDRD, R1 ; Make PORTD pins as input
LDI R1, 0xFF ; Load immediate value in register R1
MOV DDRB, R1 ; Make PORTB pins as output

LOOP1: ; Label name “LOOP1” starts here
IN R1, PORTD ; Read PORTD and store in register R1
OUT PORTB, R1 ; Make respective LED ON as per read value
JMP LOOP1 ; Jump to label name LOOP1 for infinite looping
