    I don't fully understand why only a maximum of 3 boards may be used with one sync pin. I would not be surprised if it still works with four boards anyway but if you want to be sure you can just...

    Yes indeed, since the USB port has a bandwidth of 12 Mbit/s and you have (128*128*24) 0,393216 Mbits in every frame, the maximum theoretical framerate would be (12/0.393) 30,5 fps. When rendering the...

    Splitting it up would be a valid solution, the question in that case would indeed be how to connect them together. I imagine things can get pretty complicated if you're going to render the graphics...

    The schematic can now be found here.
    I'll soon make some pictures with the oscilloscope and explain it in more detail.
  5. MultiWS2811 - Simultaneously Control 128 WS2811/Neopixel LED strips

    After having done multiple projects using an increasing number of WS2811-based LEDs, I hit a point where more channels were needed than OctoWS2811 could provide.
    That's why I created a library and...

    Have you looked into the HTC Vive tracker?
    You can get the trackers seperately but idk whether you can buy the base stations without the VR headset though...
  7. Connecting one Teensy 3.x digital output to many IC's input

    Hi,
    For a circuit I'm designing I need to connect one digital output of a Teensy to the inputs of multiple 74HCT257 multiplexer IC's.
    To be more precise, I have 32 74HCT257's and the signal from...

    After a bit of digging around I found that the reason for the limit is probably explained by the 15 bit limit of the Current Major Iteration Count (CITER) (24.3.28 p.561 of the k66 manual).
    I guess...

    I'm working on a library based on OctoWS2811 on the Teensy 3.6, and I'm trying to figure out what exactly is causing this 32K bit limit and if there would be a way to circumvent it.
    Would it for...

    I'm using the K66 Teensy 3.6 now but it still doesn't work when configuring more than 1365 LEDs per strip.
    Does the library need to be adjusted to support the larger memory of the Teensy 3.6?

    Simultaneously start multiple timers

    For a project which requires precise timings, I'm trying to align three PWM signals from three different timers; one 12 MHz, one 1.5 MHz and one 0.75 MHz signal.
    As far as I understand this would...
  13. Periodically interrupting PWM signal using DMA

    Hi,

    I've been trying to create a high frequency PWM signal which is periodically interrupted by a lower frequency PWM signal.
    By studying the OctoWS2811 library and the MK20DX256 Manual I've...
  14. Teensy Audio: AudioOutputUSB only working when combined with different AudioOutput

    Hi!

    I've ran into a bug in the Teensy audio library when playing audio over USB.
    Apparently "AudioOutputUSB" only works when there is also a different audio output (like AudioOutputAnalog)...

    I'm quite sure this is not happening here. The code runs fine, even for extended periods of time.
    But if I add one extra variable to the class, just for increasing the size of the class so without...

    Teensy 3.1 crashing, memory problem?

    Hi,

    I'm working on the code of an installation that uses a teensy 3.1 with OctoWS2811 to control leds.
    Here is a bit of an old video of the installation to get an idea:...
