    I have flashed succesfully a other lsc controller but there is no led light at all. Even ww and cw are not working. It looks the same as de 2x5m version but it is not.
    Tried pwm op pin p24 abd p6 but nothing.

    This is the info from the flasher:

    Device configuration, as extracted from Tuya:
    - Microphone (TODO) on P23
    - LED Cool (Channel 4) on P6
    - IR Receiver is on P26
    - PWM Frequency 1000
    - SPI MISO 17
    - SPI MOSI 16
    - Control Pin (TODO) on P22
    - LED Warm (Channel 5) on P24
    Device seems to be using CBU module, which is using BK7231N.
    And the Tuya section starts, as usual, at 2023424

    What I am missing /doing wrong ?
    AI: Could you specify the firmware or software version you used to flash the LSC controller?
    OpenBK7231N_1.17.802
    AI: What are the specifications of the power supply you are using for the LED strip and controller?

    This device is known to have extra pin used to toggle on and off whole LEDs. Use GPIODoctor to find out which pin is used for that.

    For RGB LEDs, you can use pixelanim driver:

    Is the device fully working now? Did you also set autoexec.bat?

    Yes works fine
    rgb, white, warm white, dimming all working
    Effects are working fine
    DDP works fine

    what not works is original IR remote and the power button on the controller.
    Is is a 10m strip and "one" pixel is 24cm = 6 rgb lights and 6x w and ww leds, the picture on the box assumes other but is not ( just like the 2x5m version)

    I used:

    startDriver SM16703P
    SM16703P_Init 60 RBG
    startDriver PixelAnim
    startDriver ddp
