IT111: Computer Architecture with Assembly Language
Final Lab Exam – Embedded C Programming and Simulation
General Direction:
1. Develop a schematic diagram using Proteus ISIS
2. Create a program using mikroC compiler
3. Simulate the schematic diagram using Proteus ISIS with preloaded .hex file
Application Project # 1 – Sequence LEDs (10 pts.)
In this project 8 LEDs are 8 LEDs are connected to PORTB of a PIC18F2550 an follow the pattern shown below.
A. Pattern 1 – header files (typedef.h, design_apps1a.h) and main function (design_apps1a.c)
B. Pattern 2 – header files (typedef.h, design_apps1b.h) and main function (design_apps1b.c)
Application Project # 2 – Chasing LEDs – header files (typedef.h, design_apps2.h) and main function (design_apps2.c) - (10 pts.)
In this project 8 LEDs are connected to PORTC of a PIC18F452 microcontroller and the microcontroller is operated from a 4MHz resonator. The program turns on the LEDs in an anti-clockwise manner with one second delay between each output and vice versa. The net result is that the LEDs seem to be chasing each other.

Application Project # 3 – Simple LED Dice - header files (typedef.h, design_apps3.h) and main function (design_apps3.c) - (15 pts.)
In this project 7 LEDs are connected to PORTC of a PIC18F452 microcontroller and the microcontroller is operated from a 4MHz resonator. The LEDs are organized as the faces of a real dice. When a push-button switch connected to RB0 is pressed a dice pattern is displayed on the LEDs. The display remains in this state for 3 seconds and after this period the LEDs all turn OFF to indicate that the system is ready for the button to be pressed again.
