  • dmanum 10 PiZeroW - Color Wheel turns white then off/on

    I figured it out finally!
    Just had to set gpio to 19 in the header of the hyperion.config.json





    PiZeroW + WS2812B working with WS281X-SPI driver and UTV007 Video Grabber. All powered by 5V 15A power supply.


    In summary, I had to plug in the RCA-HDMI to a power source (5V 1.5A TV USB port, in my case) for the Video Grabber to work correctly.
    The software part took me the longest to figure out, but after reading a bunch of forum threads I concluded that I had to edit the header of the hyperion.config.json and input dmanum to 10 and gpio to 19 (default gpio is 18).

  • dmanum 10 PiZeroW - Color Wheel turns white then off/on

    I have my pi zero 5V pin, LED start 5V pin and LED end 5V pin all sharing the same DC Jack 5V terminal (along with their ground terminals in the same DC Jack Ground terminal).


    Just want to make sure that this is a safe way to power everything as the DC Jack seemed fairly warm after two hours.


    I'm gonna mess around with the core clock config settings today. I'm also receiving the logical level converters today to try out. Will update soon.

  • dmanum 10 PiZeroW - Color Wheel turns white then off/on

    I was reading on another thread from this site that I need to keep the SPI core clock stable (too low would give white lights and too high would give black), and that under-voltage would cause issues.


    I'm not using a level shifter by the way, but I ordered some.


    Any idea how I can control the SPI clock?


    Would the level shifter correct the under-voltage (3.3v) from the Pi 0?

  • dmanum 10 PiZeroW - Color Wheel turns white then off/on

    OMG I did it!


    I have no idea, but I copy pasted the dmanum block instead of the two lines and got it working.


    If anyone needs help with this exact set up, please let me know and I will offer assistance to the best of my ability!


    Woooohooooo :D


    Config:

    Nope, I just had the Luminance set at 0.04 for prior testing and forgot to reset it. When I put it back to 1, the Hyperion startup color wheel reappeared!


    Now back to my initial problem solving! :D

  • dmanum 10 PiZeroW - Color Wheel turns white then off/on

    I was messing around with the set up today and accidentally crossed the LED's 5V and Ground wires.


    Now every time I start Hyperion, the LEDs turn white (the color wheel start up is gone) and the power cycle is still intermittent (every 10 seconds or so).


    Before I could select a color on the SSH - Colorpicker and it would briefly show the color then off then turn white within a second.
    However, when I select a color on the Colorpicker now, it turns off then turns back on to white (no more color change).


    Did I short the LED circuit? :(

  • dmanum 10 PiZeroW - Color Wheel turns white then off/on

    I am having difficulty calibrating HyperCon with my setup:


    RGB LED WS2812B connected to 5V-15A power supply and Data In connected to Pi Zero W pin 19.
    Pi Zero W is connected to USB On the Go cable to Video Grabber UTV007.
    Video Grabber is connected to RCA cables to RCA/AV -> HDMI box which is connected to the HDMI Splitter.
    HDMI Splitter Input is connected to PS4, one Output to TV, the second to the RCA/AV -> HDMI box.


    The LEDs are powered by the power supply from both ends (at first just one end of the strip, then tried both start and finish sections of the strip).


    The Pi Zero W was first powered through the Mini USB -> standard 5V 1.8A phone charger.
    Then I tried powering the Pi's 5V and Ground pins with the LED strip's 5V and Ground.
    Then I tried powering the Pi's 5V and Ground pins into the power supply.


    All my efforts have led to the same result:


    Once the Hyperion color-wheel starts, it immediately turns white for 5 seconds then begins power cycling.


    I have selected the WS281X-SPI driver Type with GRB Byte Order, LED Bottom Right Clockwise with 85, 45, 47 LEDs on the horizontal, left & right.
    Blackborder detection is Enabled.
    Linear Smoothing is enabled with Update Frequency at 30Hz.
    Video Grabber is set to NTSC on HyperCon, and the RCA->HDMI device is set to NTSC.


    I tried editing the hyperion.config.json to add the dmanum=10 line under the device block, but it still reacted the same way.


    Is this a power issue?



    Not sure if this log helps:

  • All HDMI sources

    Perfect, thanks. That could work for most of my set up, but is there a way to get Hyperion to work with smart TV apps/content?


    Just wondering about the Smart TV itself

  • All HDMI sources

    Is there a way to make Hyperion work on all HDMI sources plugged into the TV?


    If someone could point me to a thread or site that resolved this inquiry, that would be appreciated.


    Thank you,

  • Powering Pi Zero W & WS2812B LEDs through TV USB

    Would it be possible to power the Pi & LED strip using the 5V USB port on most TVs?


    I am hoping to power the Pi Zero W through its mini USB port to the TV's USB port, then solder pins 2 & 6 (5V and Ground) to the RGB LED strip.


    Would the TV be able to power the Pi Zero W along with the USB Video Grabber and other connected components along with the WS2812B 60 LEDs/m strip on a 65" TV?


    Thanks in advance!

  • WS2812B+PiZeroW Device Type: Driver Selection?

    Hello,


    I have a Raspberry Pi Zero W and WS2812B RGB LEDs.


    What driver would I select in HyperCon under Device -> Type?


    WS2812B, WS281X-SPI, or WS281X?


    Any help to point me in the right direction on the forums would be appreciated.


    Just wondering if anyone else has also had this exact set-up work with Hyperion.


    Thanks!
