I connected an LED up to my LaunchPad board to test out the features of it.
But I'm getting the weirdest of symptoms from what seems to be an unstable voltage regulator.
The voltage regulator (3.3V) will continue normally for minutes, but suddenly, its output will drop by about 200mV, and it will start swinging wildly about the place. This is measured from the anode of the LED I have connected - I do not see the effect on the cathode (which deepens the mystery further.) The effect will often happen if the reset button is pushed, or if the regulator is touched.
I assume since the LaunchPad was professionally designed the designer considered the effects of the voltage regulator. It's a tiny TSSOP-8 package, but only has to drop 5V USB to 3.3V.
