I am trying to use FastSPI_LED library with Teensy 3.0 and self built WS2801 led strips but no success… With my old Teensy 2.0 ++ it is working well - so hardware is ok. I would like to explore the benefits of more power of Teensy 3.0 … Please can anyone tell me where is my possible problem? My SPI cable connection: clock signal - pin 13, data - pin 11. ( I have tested also another possibilities written in FastSPI_LED.cpp ). Is there anything extra that must be written in code to setup Teensy 3.0 correctly? Thanks a lot!
You should use the WS2812B leds instead. Each pixel contains the ic and is ridiculously easy to work with. I buy my individual pixels from http://aliexpress.com. as for your current problem, try FastSPI_LED2
Are you using FastSPI_LED2 (note the 2)?
RC5 is the latest https://code.google.com/p/fastspi/downloads/list
^like I said…try the newer version
I am using the “normal” FastSPI_LED (not 2). I will try 2. I was afraid of some bugs because it is"just" release candidate and not the final debugged version… Do you use Teensy 3.0 with ws2801 normally with FastSPI_LED2 ? No problems?
James Dawson: now I cannot change the led driver - it was pretty hard to built my own led strips (120leds) and solder everything… The reason why I decided to built it by myself is that I want to use high quality Cree leds with better lumen/watt ratio than classic cheap 5050. Because it is for long term installation in music club I want the best possible durability and quality - not the China solution… I was working with ws2801 quite often and they were alway working as I expected. But thanks for your solution.
Version 2 (RC5) is tested and working well with the Teensy 3.0.
We haven’t added explicit support for the new Teensy 3.1 yet, but I expect that will probably come in January.
Super! It is working with Version 2 (RC5). Thanks!!!
