Just received my Sparki from Adafruit. The default program runs but I can’t upload anything. When I plug into my Win 7 PC (MacBookPro Retina), the COM port appears for a few seconds but then disappears. Neither automatic not manual upload process works.
Moreover, the Sparkiduino software blue screened my PC TWICE in the last 30 minutes!
Not a good first experience so far…
Any ideas?
PS. I am very experienced with Arduino, having designed many consumer products based on it.
