maximum cable lenghts

  • Hello,


    I made this tutorial


    http://powerpi.de/atemberauben…rry-pi-2-tutorial-teil-1/


    and everything is fine except the fact, that my receiver and my tv are ~6m away from each other (a door is in between).


    And here comes the problem:
    1) if I install the pi next to the receiver, and the power supply next to the TV, I need 3 lines back to the PI from my LED-Strip. (The 2 Data-lines + ground)



    --> lights flicker and are not well controlled, the distance seems to far.



    2) or the other way round: the pi next to the TV. So it is well working, but for the sound I need a HDMI back to my receiver from the pi. This is too long, the screen stays black.....




    Any ideas?

  • You could connect a level shifter to both end's of the data/clk line. Then option 1 would work.


    I haven't tried this myself, but have read some tip's describing this as a fix for long runs.


    Hope it help's

  • Probably cheaper and certainly a lot easier to get a pi zero .


    Level shifter can be had for under .50 cents usd. each. And adding it to an existing setup is just a matter of simple wiring. I'm puzzled.

  • Both options sound good!
    I also found a software called Hyperion capture for Windows.


    For the first, I put my Pi3 behind my TV for now...
    The sound is sent back via TV to my receiver that works....
