My crisp new Due arrived last night, and I can't wait to
let the smoke out power it up.
But I have some serious questions that need to be clarified. Hopefully the answers will be helpful to the many others asking similar questions!
OK. The Due info sheet http://arduino.cc/en/Guide/ArduinoDue is quite confusing, as it says that the board may be powered from the USB port, but then a paragraph later it says it can't, and it must be powered by the DC adaptor if the board is a host.
So could we get some clarification, specifically : -for testing, "first light" purposes (i.e. out of the box), what is the best method for powering the board?
This isn't explained anywhere, and would be an excellent item to add to the blurb sheet that ships with the unit, just so we know. A simple line diagram would be very helpful to prevent any potential release of smoke.
Can I program the board when it's just being powered by the Programming USB port?
Should I also remove any Native USB device at that time, or is it safe to leave in? In other words, can both USB connections be powered simultaneously, if I'm using the Native port from a powered hub, etc? Following on from this...
If I have a (second) USB target connected and powering the board via the Native USB port, when programming, can I just stick in the Programming USB connector, or should I only ever program on DC power?
Perhaps a simple "howto" thread, aimed at novices (I've been designing and building MCU projects for over a decade, but this is my first ever Arduino) could help prevent accidents and frustration. Could another Arduino image be used for this?
Ummmm... I think that's it for now. I hope this generates some interest and helps to improve the documentation. I'm happy to help out in any way I can - but right now, I know nothing!
