Resolved the issue tonight; I found another Micro USB-B cable, if you look in the 'A' plug there is a white piece in the plug. Other Micro USB-B cables have a black piece. May or may not be significant.
Any way with Driver signing enforcement disabled and executing the "Install Driver - 64-bit.bat" file with administrative rights, I was able to load the driver. I ran two sketches; blink example and the Difi server example.
I hope to start moving a project from the Arduino Mega to the Digix; it reads current weather observations at 15 minute interval, writes data to a SD card, and uses a web server to output data. Also, it has a download link for the collected data from the SD card. Not all my coding; I did add some timing logic and a couple of functions to simplify code. Project uses DS1307 Real Time Clock, BMP085, and DHT22 sensors.
Is the Digix, Real Time Clock compatible with the DS1307?
Thanks for hosting the support forum!
