I accidentally took a 24V instead of a 5V PSU to power the Discovery 2 device. When I probe use a multimeter to read the voltage between GND and +V I get 0V. Also the waveform generator, when hooked up to a scope, doesn't seem to output anything. Did a toast my Discovery 2? Note that the polarity was (unfortunately) correct so I suspect there wasn't a diode or anything else that protects the board inside the Discovery 2. The LED in the center is still flashing.

Is it possible to create custom waveform similar to the attachment? I see there are options to create a list of values. However, I don't see an option to define the duration each value should stay at.
