Hi !
Here is my modest contribution to the digispark :
http://opensource.grisambre.net/digisparkau3/ to save you an hour of coding...
This is a quick code I wrote to ease communication between an autoit3 language program and a Digispark using the Digispark USB protocol.
Don't hesitate to report any bug !
A simple example is included with the code.
Have Fun and Best regards

Nicolas
