    LED Tutorial files. Where are they?

    by timbrass » Mon Mar 07, 2022 12:41 pm

    The "USB to LED.pdf" guide talks about downloading "MadMapper_LED_Tutorial_Files.zip" from Yourspace.

    It's not in the MadMapper.com downloads. https://madmapper.com/yourspace/ does not exist anymore.....

    Anyone know where to find this file?

    Thanks for the files. I can run the sketch "FastLED-serial-only-single-line" and if I unblank "#define JUST_TEST_LEDS" then my single strip of 25 x WS2811 LEDs (no clock pin) on an Arduino Uno blinks as expected. So the Arduino/Com3 is working...

    When I go into MM DMX Output preferences (I have nothing in DMX input) and set Loopback 127.0.0.1 and Route Artnet to USB LED devices and click + to add new routing I don't see anything in the "Out LED Device" dropdown and "Setup LED Devices" shows nothing I can configure. The tutorial implies I should see a device in the dropdown.

    So my question is - How do I populate the "Out LED Device" dropdown in Preferences/DMX Output to include my Arduino?

    BTW I have a Teensy 3.2 on order in case MM is hardcoded to look for specific hardware devices, but was expecting an Arduino Uno to work for 25 LEDs on one strip...

    Ahh...Just seen a similar question from CaseyJScalf....

    My VID(s) on my USB-Serial COM3 device in Device Manager is:-

    USB\VID_1A86&PID_7523&REV_0264
    USB\VID_1A86&PID_7523

    So my Teensy 3.2 arrived and I installed the "FastLED-serial-only-single-line" sketch. Serial monitor shows "Setup Done".

    In MM preferences I can now see Teensy(com4) on the Out LED device dropdown. I can see output in the DMX monitor and I get some vaguely relevant activity on my 3 (+,- and data) pin 25xWS2811 LEDs.

    However not all the LEDs are lighting and some colours are odd, so I clearly don't have the Fixture Editor settings correct.

    One thing that is odd is that the sketch sets the baud rate to 921,600 but in MM preferences it always goes back to 4,000,000 even when I try and change it to 921600.

    What baud rate should I use? Why does MM keep setting it back to 4000000?
    What should be the fixture settings for a single WS2811 string of 25 LEDs (+ve, -ve and data pins)?
    The Fixture editor needs some better documentation!

    I tried various Fixture settings and briefly managed to get all 25 lights firing (right pattern but wrong colours - first 4 lights white the rest Red) by using Garagecube SFX-01 W 1m with Pixel width of 75 and Pixel size of 1 and Pixel type L. I now can't reproduce that working so its seems very fragile.

    When it was working with a setting of width = 60 only 20 lights lit so the 75 must be 3x25 (one for each RG and B??).

    Perhaps I need more than 1 Universe? If my 25 lights each need 3 values up to 255,255,255 how many channels do I need?

    The fixture editor needs more documentation!

    Have you tried changing the number of elements?

    Teensy thing is tricky. For a proper setup, you'd better use a LED driver (Advatek Pixelite, Falcon, Enttec...)

    What is the lowest cost way to connect my PC to my WS2811 string? (I can't get Teensy to work) I need some box that takes Ethernet (I assume ArtNet only works on Ethernet in and lets me connect the 3 wires from my LED string. Does such a device exist? I want the equivalent of the Enttec Open USB/DMX box but for ArtNet and WS2811.

    There are a bunch of Pixel Drivers out there, Advatek, Falcon, Enttec...
    I know a bunch of people using Advatek Pixlite and have one for testing: https://www.advateklights.com/pixlite-4 ... trol-board
    There is a list of devices here: https://www.facebook.com/legacy/notes/2672135769484381/
    There's a cool facebook group for this kind of subject: https://www.facebook.com/groups/myleds
