  • [Solved] Hyperion Flicker Issues(2)

    *Solved* Fingers Crossed

    Originally had 2 issues.
    1) White Color Only Flicker - Symptom Intensity Change from Bright to Medium Bright by itself.
    2) Grabber Disconnect - Symptom LEDs would go back Background Effect several times a second for short duration.

    Solution to problem 1:
    Replace Adafruit I2C/SPI IO Level Lifter with Arduino
    --Lesson: 'rate' and 'serial rate' are the same. Corresponds to serial baud rate.

    Solution to problem 2:
    Enable Smoothing
    Decrease Update Frequency to 15 Hz
    Changed time to 150ms instead of 200ms
    --Lesson - O that is what that is for!


    Settings I kept:
    720x480 at 30 fps for NTSC and PixelDecimation 2

    Note:
    I switched from Pi 0 to Pi3 because I dont use USB Hub.
    A hub is needed to connect grabber and arduino to pi zero

    TLDR:
    - Problems with flickering?
    Try lower the smoothing frequency and lower the framegrabber frequency in your Hyperion configuration.
    -Problem with Single Color Flickering
    try an Arduino Uno Rev 3 or higher.

    sometimes the usb video grabber get not enough current...if you have a powered usb hub, try to check if this is the problem...


    Thank you for the suggestions.

    TLDR: Issue Not resolved.

    Test Performed:
    Soldered Peripheral 5V direct to Easyday Grabber ( Onto 5V to 3,3V regulator )
    Note: I have 3x 5V buck regulators supplies. 2 for LEDs and 1 For Peripherals. All GNDs are connected from Astec 24V supply ( source)

    Results:
    Voltage went from 4.86V ( No Mod) to 5.06V ( W/ Mod ) while operating.
    Flicker back to Solid Color Effect persists. Changed Grabber settings around.
    No further observable differences. :/

    Issue: Grabber Disconnects and Reconnects fast
    Has anyone any idea what is happening and or how to fix?

    "device": {
    "rate": 1000000,

    },

    rate should be the same as on your arduino sketch...

    Firstly, thank you for your help.

    Changing the rate did the trick. I did some testing.

    Flickering while solid white is fixed WITH Arduino in Communication chain.

    Results:
    Can now Test White color reliably with no flicker.
    Can now lower brightness reliably with no flicker.

    New Issue:

    What happens - Intermittently LEDs go crazy, on still image. Leds for a split second return to Effect.
    Can have no issues for a couple of seconds.
    Not observable in Hyperion Screen Capture TV


    Tests I have performed.

    NTSF or PAL
    Any Standard Resolution ( from list )
    Any Hz, 25, 30 or Auto
    pixelDecimation-1 - 14 tested
    Crop numbers varied ( Random order )
    Disabled: Smoothing ( Reason: LEDs go Crazy )
    Disabled: Black Border Detection ( Reason: Just Testing)
    Enabled: ForegroundEffect - Color - Red (Reason - Noticed When Grabber is disabled effect activates )
    Swapped Mail to Mail on Yellow RCA
    Placed 470 Ohm in series on MOSI ( Data Out)

    Has anyone any idea what is happening and or how to fix?
