Test Plan/Results (Mc)

The Microcontroller's port B, Vcc, Ground, Port a and port E were all used for the functionality of the LED's display. To test the microcontrollers ports we put LED'S on breadboards to make sure that the three: PA0, PA1, PA2 were decoding properly in order. We expected the following results where PA0 = C, PA1 = B, PA2 = A.

C          B            A

Row 1:         H           L             H

Row 2:          L           L             H

Row 3:          H           H            L

Row 4:          L           H            L

Row 5:          H           L           L

Row 6:          L            L           L

We then set the clock with Port E (PE3) with a delay of 200 expecting a good speed of the word form left to right.

Results:

The result was that the decoder did move through the pattern successfully but the delay was to short and therefore was increased to 400.
