PIC Discussion | by Eng. Tamar Jomaa

Example#1:

Addition of two numbers entered to portB and display the result

on portA.

Solution:


Example#2:

Subtraction of two numbers entered to portB and display the

result on portA.

Solution:


Example#3:

Check if the input number from PORTA is larger than 10 or not.

If the number is larger than 10 then a LED on RB0 will be on.

Solution:

Solution#1 solution#2


Example#4:

Half Adder program.

Solution:


Example#5:

Full Adder program.

Solution:


Example#6:

Implement 4 bit XOR.

Solution:


Example#7:

Move the content of RA0 TO RA3.

Solution:


Example#8:

Move the content of RA0 TO RB3.

Solution:


Example#9:

Multiplier to multiply two 3 digits numbers.

Solution:


Example#10:

Implement square of PORTA.

Solution:


Homework

1) Implement 8-bit decoder with two enable pins.

2) Implement 4-bit multiplixer with 2 enable pins.

3) Implement 4-bit buffer with two enable pins.

4) Implement 4-bit gray code.

5) Implement a single bit comparator.

6) Implement 4-bit divider.

7) Implement 4-bit XOR/XNOR device with select pin.

8) Implement 4-bit "AND-OR-NAND-NOR" device with

select pins.

9) Copy the input data from PORTB to all GPR.

10) Implement 4-bit L/R shift register.

Notes:

Delivery Date is 6/10/2010.

Any late homework will not be accepted.

All copy-paste homework will not be accepted and both will

take ZERO.

Each question implement the PROTUS simulation and you will

implement the code in MPLAB.

So I will receive CD that has all PROTUS and MAPLAB program

for each part.
