So… the mote sticks are too big to fit on my current project. I saw the thread about cutting mote sticks and may resort to doing that, but then I thought “Mote sticks are just APA102s, so I could wire up my own strip of these and run them off the mote controller!” So I sliced up a USB cable and wired it to a strip of APA102 LEDs, as shown:
The problem is, when I plug in the USB Mote Controller, a random selection of the LEDs on the strip light up, then stay lit up whatever I do. Here’s an example of running rainbow.py from the examples, showing the proper mote sticks behaving properly, but not the APA102 strip:
While the mote sticks cycle through the rainbow happily, the strip stays static. And it doesn’t matter which port on the controller board I plug it in to…
Any ideas what I might be doing wrong?
