This is the wiring I used to use the octosWS2811 with apa102 leds. note that the power is provided by a 5v power brick attached to the LEDs with a tap to the octoWS2811. The green and blue wires are used from the ethernet connector to provide the SPI connection. The black connector plugs into a socket on the LED’s that was there from the factory (Ray Wu).
Awesome! Would you allow me to use your photo on the product page for this board? Of course, I’d mention you a link to your info here.
Feel free to use it. The Teensy has been a great help to me:-)
Thanks for the pic!
Did you do anything special to get this working? I’m trying the same setup based on your photo and not getting any results (random static colors all along the strip).
Any specific speed settings in code?
@Lucas_Morgan what are your current settings? There’s been a lot of exploration lately with how to get APA102 working on hardware SPI. Some suggestions: Dont OC the teensy, try 72mhz. Although the hardware SPI can go up to 21mhz, people have had better luck goingdown to about 8 (YMMV)
@Steve_Caress1 (or @PaulStoffregen )
Where do you find those blue screw terminal blocks, and what exactly are they called?
Search on Digikey for “Terminal Blocks - Wire to Board”, and when you get to the list of 22921 matching parts, choose Pitch of “0.200 (5.08mm)” and “Positions Per Level” of 3 and “Number of Levels” of 1, and click “Apply Filters”. That will give you a list of 321 parts. Many have pictures in the list, so you can easily see which type they are. Almost all of those 321 will work.
Thanks a million!
Hi Steve,
I want to put to same setup together do you have any code to share to help me get started?
@Greg_Heinz
Have a look at the FastLED library. It comes with example programs, works brilliantly with the Teensy, and supports a whole range of LED types including APA102, WS2811/12 and many others (including support for the OctoWS2811 adapter).
The idea of this connector is so helpful. Powering up Teensy from the same source save money(one less power supply), and make everything else way much easier.
I have applied the same idea powering up other projects . Thank you.
