Lab 2.1: Introduction to the PIC 16F84A

• Objective: To get familiar with the PIC 16F84A microcontroller.
• Assignment:
  • Read the brief overview of the 16F84A.
  • Read the quick and dirty tutorial to program the 16F84A.
  • Program the microcontroller using a C language program found here. The microcontroller should drive a 7 segement display so that it counts '0', '1', ..., '9', '0'.... The TA will provide the parts and show you how to connect them.
  • Modify the program so that it counts up ('0', '1',..., '9', '0' ...) if RA0 = 1, but otherwise it counts down ('0', '9', '8',... '0',...).
• Lab Report: In your lab report, include your modified C program. Explain the parts you used and how they were connected (include a circuit diagram). Describe any problems that you encountered.
