Assignment 2

Hardware Tasks

This assignment is based on C language programming skills and PIC18f4321 programming skills. The weight of this assessment is 20% of the unit final mark.  

Q.1 (a) Write a program ON a LED when a switchSW2 is pressed once and OFF the same LED when the same switch is pressed again. (should change the LED ON/OFF state every time when the SW2 is pressed)

(b) Write a program to run a DC motor connected to pins 1A and 1B in CW direction and reverse it when SW2 is pressed.

Q2. (20marks)

Write a program to display (on 7-segment) continuous up-counting numbers from 00 to 99 (in the decimal system) when switch SW2 is pressed and released and down-counting when switch SW3 is pressed and released.

Q.3. Write a program to read analog input from RA2 when SW2 is pressed and display the following messages on the LCD panel. “input is <= 2V”, “input is < =4V & > 2V”, “input is > 4V” depending on the actual real-time analog input. ( if the message goes over the first-row display area, it should display on the second line) ( For testing your program: Use a 10kΩ potentiometer in the following configuration to provide the analog input. Use any of the GND pins in P2 as a ground connection and the female socket next to PICkit3 connector as +5V and connect the mid pin of the pot to RA2.) (30 marks)

Q.4. a program to display whatever you type on your computer keyboard on the LCD display and change the color of your computer monitor (emulated dummy terminal)as follows: S2= RED, S3= Yellow, S4= BLUE and quit the program when S5 is pressed.(you need to connect your PIC development board to your computer via USB to serial cable for testing this) (30 marks)
