Problems/Solutions (SR)

Some of the problems that we encountered while using the shift registers was that the function generator was not outputting a clean square wave. The square waves offset was such that there was a negative voltage entering into the clock. As a result we used the Axeman's PWM from Port E. Another issue we encountered was that we left pin 13 open making the assumption that it would be considered a ground. The shift register did not read it as ground and therefore did not operate correctly and had to have that pin forced to ground.
