Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

Write a function to generate an output voltage of 0.5V on the CCP2 pin. Consider a resolution of 12 bits, a fosc of 16MHz, Vcc of 3.3V and a Vss of 0V. It is necessary to include the proper pin configuration.
Write an assembly language program (not C programming) for the PIC12F675 microcontroller to implement the following function: A single 7-segment LED numeric display is to display the number of people in a room. The number is ranging from 0 to 7. There are 2 inputs: Input A is a logic HIIGH pulse lasting 0.5 seconds to signal that a person has entered the room. Input B is a logic HIGH pulse lasting 0.5 seconds to signal that a person has left the room. There are 4 outputs: 3 lines are for the BCD value up to 7. One output line is needed to flash the display if the count exceeds 7. Use a 4511 7-segment latch/driver/decoder IC. If the count exceeds 7, then display a 7 and flash (turn OFF and ON) the display at a rate of 2 Hz. List comments telling the purpose of each section of your program.
