Hi all,
We are currently evaluating using the PixelBlaze V3 as a primary LED controller in our art pieces (9 foot tall interactive 3D-printed cat statues). We have use a Raspberry Pi as primary controller, and were planning on controlling our LED strings directly from the Pi GPIO, but the PixelBlaze looks like an attractive alternative.
Since the PixelBlaze is another controller, with it’s own internal state, we want to be able to keep it’s state in sync with the state of the control scripts on the Raspberry Pi. To this end, we need a way to communicate bi-directionally between the host and LED controller. We’re aware of the WebSocket interface, but would prefer to use a wired interface if possible.
So, my question is, can the PixelBlaze be controlled via something like a USB-serial interface?
After further investigation, it seems the data lines on the USB connector don’t connect to anything, so I guess that answers my initial question.
