    Following up for anyone that is interested.

    It looks like there are 2 bugs. the first is common to both 3.1.6 and 3.1.8, and is a bug that kicks in if the assigned number of strips is 1. The...
  2. FastLED v3.1.8 not working in parallel with teensy 3.6

    Hi - I am trying to build a test rig to use FastLED in parallel with a teensy 3.6, and it is not working as expected. When I use the following sketch, which cycles a strip through the rainbow and...

    yup - it's kind of a lot of work to perform an experiment on with a LOT of LEDs on the line. I'll do some bench work on the APA102s for fun, but plan on WS2812s for the project. Thanks for the...

    hmmm - that is very good info. I was looking forward to the better low brightness performance. What do you think of having multiple arrays of APA102c LEDs on different pins - so the max number on a...

    What is a large number of APA102c LEDs?

    Hi all,
    I've done a lot of work with WS2811 and variants in fastLED. When I do a large number, I run them in parallel. I am just starting to experiment with the APA102c, and I am thinking of a...
  6. MSGEQ7 maximum output voltage and teensy 3.6

    Hi - does anyone know the maximum output voltage of an MSGEQ7 if it is using 5v supply? The data sheet says it operates best at 5v, but I can't figure out what that means in terms of max output...

    I think that is probably right! I will check it tomorrow. Thank you so much for your help! You have saved me all the time that I anticipated resoldering everything. My coding chops are way out of...

    Thanks guys! It does work! I had come at this a much clumsier way by using a counter instead of millis, and limiting the counter to about 20,000. That also worked but it had a seam when the...
  9. The floating point calcs with the rapidly...

    The floating point calcs with the rapidly increasing millis are my suspect as well. I tried converting all of the calcs to integers and using the sin8 approximation in fastled. I was about 30%...
  10. Everything works fine then dramatically slows after about a minute

    Hi - I am running an 8x32 matrix on a Teensy 3.2 using fastled in parallel. I'm displaying a sinusoid function. It works fine for about a minute and then slows to a framerate of about 2FPS - and...

    Hi again - Switching from LED_TYPE WS2811 to WS2812 appears to have resolved this problem.

    Hi Paul!

    Here is the code for the DemoReel100. The Octows2811 library seems to be working fine. I would use it, but I need to do 12 strips in parallel. The only thing I added to this example is...
  13. Teensy 3.2 Octows2811 fastled flickering problem

    Hi - I am having a flickering problem with the fastled library. I am using Teensy 3.2 and fastled 3.1.6.

    I'm not doing anything complicated - just getting the hardware set up and tested. The...

    Another thumbs up. I am using the CD74HCT245E to drive 12x5m of 12v ws2811 strips over 30 feet of cheap thermostat cable and it works great. This little chip solved a problem I have been having for...

    Adafruit 3.5" TFT HX8357D noise problems?

    Hi,
    I have this running (erratically) with SPI using the ILI9341_t3 library. It was starting the graphic test examples and then white screening after a couple of seconds. I added 100 ohm resistors...
