Use DIP switches to demonstrate the microcontroller's ability to use digital inputs and perform mathematical operations. The result is displayed on an LCD.

  • I think micro-controllers are harder to understand than switches.

  • this a ppi8255 or what IC you use in the circuit ??? i need make a circuit with a dip switch and ppi 8255 you can help me :-(

  • THANK YOU SO MUCH! I don't have a nerdkit, I've just been working with AVR's - but your source code finally answered my question of how to read a pin's value. I didn't know that PINxn wouldn't work for conditional controls - but your suggested double-shift technique seems to work! THANKS! *****
