LSC Smart Panel Lights OpenBeken RGB SM16703P Configuration for BK7231N - troubles

Hey everyone,

I bought the LSC Smart Panel Lights from action. With BK7231N inside I flashed OpenBeken on it through UART.
But I'm struggling with the firmware to get the RGB + W working.

Right now i'm running this config


But It's not really working. So far im getting the white leds to power on and are dimmable but no RGB yet.
Anyone got any pointers to what is going wrong?

I can post more info, just tell me what's needed and i'll get it.

Thanks in advance!
AI: Could you share how the RGB channels are wired in your panel—specifically, which pins on the BK7231N are connected to the RGB LEDs or their driver ICs?
Pin 9 is connected to the controller IC. And set to SM16703P_DIN
AI: Do you have the SM16703P protocol enabled or configured in OpenBeken, and if so, could you share those settings or any relevant logs?
Yes its in the command

Hey, can you specify how it should work? Do you want both RGB and W at the same time or separate RGB + W modes?

xref with @cyclemat thread for the same device: https://www.elektroda.com/rtvforum/topic4162583.html

The RGB not working might be because P16 should be set for SM16703P_DIN. I think you can even unset it because it should default to P16. Unsure if setting it to incorrect IO will be overridden though anyway, in which case there's another issue.

I'm not sure on the function of


Added after 24 [minutes]:

P14 can be reused as SPI_SCK
P16 can be reused as SPI_MOSI
P17 can be reused as SPI_MISO
P15 can be reused as SPI_CS

I wonder if SPI_CS and SPI_SCK are even used for anything in this device.

Let's continue in the other thread to keep the overview.

I can close this topic if required, but I will note here one thing.

I don't think P9 is used for WS2812/SM16703P. Only P16 is supported for this on Beken, because it's using hardware SPI. Where did you get information that it is using P9? Futhermore, OBK automatically uses P16 internally, so setting this pin has no effect on firmware, it will always use P16 because only P16 is hardware SPI MOSI pin.
