    I spotted this happening again.
    I found 1.5.3 had been released so have installed that and updated udev.rules. However, teensyloader is still using a lot of CPU if no teensy is connected. It stops...

    teensy loader gobbling CPU

    I'm running teensyduino 1.5.2 on Debian 9.

    Whenever there is no teensy connected, the loader is consuming CPU (currently 68% of one core).
    It does this regardless of whether I unplugged a working...

    Not really unresolved - my code seems to work fine with your fix.

    I'm just curious as the effect of that bug : what does that counter do ?

    I've just noticed that the OctoWS2812 library uses pin 12 for frame sync.
    I'm using pin 12 for MISO0, but I'm not doing multi-teensy video syncing.

    I can see that pin 12 is manipulated in the...

    The idea is that it doesn't do more than 1 transmission per millisecond, though I agree it's a bit dodgy. The message it sends lasts about 800us.

    But while not calling that code stops the problem,...

    I have the code below to regularly send out some MIDI values. I'm also maintaining 4 strings of 360 WS2813 LEDs using the octows2811 library on a teensy 3.5.

    Yes, I realised I was wasting the memory - I'd had to disable the double buffering when I used too much earlier. I just hadn't realised I couldn't use all 64K for display memory.

    Teensy on TV

    The BBC don't credit it, but it's a Teensy 3.2 controlling the LEDs (it's only an AVR controlling the fingers ..)

    Maximum sizie of WS2811 displayMemory

    I'm using teensy 3.2 to drive 4500 WS2811 leds. For $reasons, they're connected to only 3 of the outputs, so ledsPerStrip is 1500.
