Flickering

  • So, I installed about 4 meters of APA102 under my cabinets. My issue is, there is a break (about 2 meters) between the sink and about a meter of LEDs. The last meter will only respond properly when saturation is full. If it's let's say 30/30/30 the lady meter just flickers like crazy.


    Would a logic lever shifter help? Or should I install "ghost leds" in the gap and just wrap with tape to hide the LEDs?

    it would waste 2ms leds, you could be right with the level shifter, it was my first thought too... its just a few dollars...you should try it before you waste those leds :)

  • It's one larger supply 20A.... I checked the wiring... Actually required the whole thing... Seems the issue only comes when it goes over the stretch above the sink... I checked the clock and data and it says it's at about 2.9v...


    Seems to have gotten slightly better but definitely not perfect... If set the RGB to like 90/90/90 the last set starts to flicker. Maybe I should clarify, it's more like a twinkle... Random LEDs flash on and off and at different colors. I also strung them all together and they work perfectly if that stretch of wire isn't installed...


    Is there something I should be adjusting INSIDE Hyperion? Baudrate or the Hz?

  • How did you measure the clock and data voltages ? Just a multimeter or using an oscilloscope ?


    Dropping the baud rate would be a quick test - any signal reflections between the strips will be worse at higher frequencies.
    Assuming you're using the default 1M, try 100k or 10k


    I don't know the output drive strength of the apa102. Interference from other devices could be an issue.

  • I used multimeter.


    I'll try dropping the baud rate tomorrow.


    So if I get what ur saying, the higher, the more exaggerated the issues. And what exactly is a baud rate (as you can probably tell, I'm a total NOOB
