  • Effets étranges ...

    Je pense que ton alimentation est sous dimensionnée, 12*5 = 60 W
    Tu as plus de 200 led + le Pi.
    Je connais pas SK9822 mais pour APA102 (ce que j'ai) on compte 1W maxi par led. Si pour SK9822 c'est pareil je te laisse conclure.
    Cherche du coté de l'alim et de la puissance.

  • SECAM video input

    Les barres vertes sont "normales". Pal/Secam on s'en moque d'ailleurs je me demande si le secam n'a pas disparu...test en ntsc si ton convertisseur te le permet.
    A quoi ressemble ton convertisseur ?

  • Rien ne fonctionne

    Salut,


    Es tu sur que la masse et bien reliée au Pi, à l'Alim et Led ?
    Je te conseille également d'utiliser un Level Shifter, fais une recherche sur ce forum pour trouver des infos.


    Merci de poster ton fichier de configuration.

  • Changing Leds ws2801 / Apa102

    Thanks for the answer :)
    i bought a new apa102 led stripe but no time to test yet :(


    Are you using the level shifter from lightberry ?
    Do you know how the cable of the level shifter is connected ? i mean is the order "+,clk,data,-" or "-,data,clk,+" when you look at the led connector ?



    Thanks !

  • Changing Leds ws2801 / Apa102

    Well, the GND and +5V was not matching.....so i suppose that the clk and data was not match
    I cut the first led , and soldering in the right way but nothing works. I suppose the led strip is broken.
    Does anyone know a way to easily test the led strip?

    This is a V4l2 grabber (utv007)
    The start effect (rainbow swirl) doesn't work.
    May be a power issue ?
    When i check the power at the start of the strip i get -0.5V. (I put the black pin of the tester on the GND and the red one to the 5V), why i get negative power ?
