While running through a few tutorial / getting started I ran into a couple items with my Panda II:
- I am unable to blink the onboard LED as described in the getting started video. FEZ_Pin.Digital.LED doesn’t seem to be the right pin on the Panda II.
- I put together an LED on my breadboard driven via a transistor, and I initially connected the transistor to the D20 port on the Panda (right side set of pins, 2nd from the top on the left-hand column). FEZ_Pin.Digital however doesn’t have a D20 pin, nor does it have a Di20 pin. There’s not an “IO20” pin either (though there is an “IO21” pin). I connected the transistor to the D21 pin and tried FEZ_Pin.Digital.IO21, but that did not work. Connecting it to D0 and using FEZ_Pin.Digital.Di0 worked as expected.
As for powering the Panda and the other things on my breadboard (currently, a big pile of LEDs and a shift register), how much is it safe to draw from the “5V” port on the Panda? At what point should I start powering things from elsewhere?
Am I correct in assuming that I can power the Panda with the “Vin”/“GND” ports? Does that voltage need to be 3.3v or can it be 5v? How should I set this up, assuming the only power supply I have supplies either 5v or 3.3v, but not both at the same time, and my LEDs etc need 5v?
