Only white led color appears, looks like dont communicate the arduino

  • Hello!
    My setup
    Raspberry pi3 with libreelec
    Arduino uno (chinese clone)
    WS2812B led strip


    Well, I will try wery wery lot possibilities but still nothing.
    Firts, i install the led strip correctly, I connect the data cable the arduino data pin 6, with a 470ohm resistor.


    Then I install a test arduino sketch. Neopixel strandest. The ledstrip is working well, every colours, rainbow colours. So the arduino controll the led strip well!


    Then I will install the right sketch to the arduino. [MEDIA=pastebin]WPEMEyKv[/MEDIA]
    Yes i set the data pin 6, I setting up the baud rate. (I try all possible baud rate), And I set up the number of leds.
    (I try 3 different ambilight arduino sketch, but all of them do the same thign)


    I install the hyperion correctly, I set up everything, the number of leds, the baud rate, the TTYUSB0, and etc.
    I send the config to the to the raspberry, [MEDIA=pastebin]hZaq1i9y[/MEDIA]


    I make this steps about 100 times, but nothing.


    When I push the start stop button at the Hypercon, the white colour run arround my TV and stuck until I pres over the start stop button. When I try to set up any colurs, the log say this


    Set color to 255 205 125
    ssh out: /storage/hyperion/bin/hyperion-remote.sh -c ffbd83
    ssh in: hyperion-remote:
    ssh in: version : V1.03.3 (brindosch-2fbbcff/2f01dfa-1495880388
    ssh in: build time: Jun 3 2017 02:06:16
    ssh in: Connected to localhost:19444


    So it looks like good, but nothing just the white light.


    I try an othet ambilight program in windows, the name is ambibox. But still nothing. When I choose the correct COM interface the white colour run arround my TV and stuck in. Like the Hyperion. And when I try to setting up a colour still only the white led lights. So something is working, because the program says connected, and the white colour run aroound, bud I dont know why do this white colur thing.


    So i think my hyperion config is good. I think the usb connection or the datapin connection is bad. But this is only an idea. The usb cable is good, because I use this cable to upload the sketch. :( Or myabe the chines arduino is bad? But when i will upload the "test" sketch the arduino work well and I see all colors.

  • Thank you! I will try it afternoon. But I think I have different problem, but I dont know why bad. I have an other chinese arduino clone, I was use couple years ago, this arduino controll an Bluetooth RC car, so work well, but I uploaded the ambilight sketch and still nothing. There is no test colours. But when I upload the fast led library test programs, the led strip and both of the old and new arduino works well!
