    if anyone's interested, I got a usbasp working today with Hyperion and https://github.com/poljvd/hyperion-usbasp

    It's a $2 USB device designed to program avr microcontrollers but can be reflashed to drive ws2801 or ws281x led strips < 256 LEDs long.

    If you don't already have an avr programmer you need to buy 2 of them so you can reflash one.

    Let me know if you want more details or the pre compiled hex code for it

    Hey penfold. thank you for your work. Thats exactly what i am searching for.
    Unfortunately i have the APA102 LED Stripe.
    Are you able to add support for it?

    Greetings Julian

    It might already have support ? If not, it won’t be far off.

    I notice there’s ws2801 support which is also SPI ?

    I don’t have any SPI addressable led strips so can’t test anything but can point you in the right direction here

    that would be great, thank you.
    I ordered the usbadp already and it should arrive thursday. I'll write my experience :)

    While this is a neat thing to do when you have some USBASP laying about, why wouldn't you just get a 2$ Arduino Nano with more CPU power and full FastLED support if you are ordering "fresh"?

    Hmm good point, i am new with this.
    Searching for Arduino nano i only get Artikles with ~20$.

    I want a compact controller to plug in my Windows computer.
    From there i want to play Movies via HDMI on my TV and controll die LED´s directly.
    The USBASP was for me the cheapest solution i found.

    Can you link me a better alternative?

    Wow great my swabian hearth is lucky :D
    Ok than i will use this instead.

    But because i already ordered the USBASP i will give feedback if APA102 is working.

    Thank you very much.

    Thing is, you need 2 USBASP or an USBASP and an Arduino to flash the USBASP in the first place.
    On aliexpress, you can get the nano for 2$, and it can be programmed with USB directly.

    Oh i didn´t know that.
    I just experimented with the raspberry pi as controller when i saw your USBASP alternative.
    Ok i will try to cancel my Order and use the nano instead :)

    So in my opinion there is no advantage using your USBASP!? (Except you already own one)

    The form factor is cute - but no, there’s no electronic advantage to the usbasp
