    Problems with Madmapper, Teensy and led numbers on

    by EduCortina » Mon Apr 01, 2019 9:53 pm

    Hello, I wanted to consult you a question and problem that I have with the connection through Madmapper, Tensy 3.2, and the titorial of MadMapperLEDTutorial_files 2.
    The problem is that using different types of LED strips such as a 5 meter strip or a panel of 32 by 8 LEDs, they do not all work, they light up on the 5 meter strip a little more than half and on a panel of 32 meters. 8, light up 177, I have changed the number of Leds in Madmapper and everything is the same, the two plates are supplied with a ring and they still do not illuminate completely.
    I have tried with other codes, programming in Arduino that come in the zip file and they do get illuminated all.
    Will something have to change in the programming for the Teensy?
    Thank you very much everyone in advance

    Do I understand correctly that you are using different brands/chips of LED's?
    Then maybe with a teensy and octo board you can add them in different universes, but when in one long string it wouldn't work because of the different way of data.
    I guess you also need to tweak the tutorial code to accept multiple brands of led's for the different outputs

    Hi,
    you may need to add more DMX universes. 1 universe controls 512 channels. If every LED uses 3 channels (R,G,B) this means you are controling (512/3) about 170 LED points.
    This subject is covered in the "madmapper LED output tutorial" on page 7 out of 8.
    Multiply by 3 the total LED number you want to control and then divide by 512 to get the number of DMX universes you need.
    hope this is still relevant for you ;)
