This example uses an infrared-coded signal from a home remote control to illuminate the infrared photodiode on the LaunchPad. The signal PA24 is introduced to PA26 by the Dupont wire, which is the positive phase input of the comparator. The signal of the infrared photodiode is filtered using a staggered comparator. Use LA to observe the output signal of the comparator, indicated by a flashing LED. This routine only observes the filtered infrared signal from LA and does not decode it.
