I am a beginner but I love to jump into things and learn while in the process of making something. I am not worried about programming the device, but more of how to build it, as I do have a little bit of programming experience. My first question is, is there anyway to "stream" the information from my pc to the cube instead of having to program the chip, remove the chip from the programmer, and then put it ...
