Action LSC 3202086 Addressable LEDs flashing with OBK for control cloudfree like in Tasmota/Esphome

Question

LSC 3202086 LSC Smart Connect XXL LED strip is a individually addressable (WS2812B-like) LED strip with extra two PWM channels (RGB + CW). It is using BK7231N module, so you can flash it with OBK: You can check our flashing guides for more info on flashing Beken chips: Brandname: LSC Product...

Hello there ! Do you have success with this led strip ? I bought one yesterday, did a backup , extract config , but no way to get some light after flashing ... Here is my extract : Code: text Expand Select all Copy to clipboard {    Jsonver:1.0.5,    brightmin:10,    gmwb:75,    title20:0,    cdtime1:60,    1err:40,    cdtime3:180,    cdtime2:120,    totallen:1000,    gmwg:70,    knum:1,    leaderr:15,    wfcfg:spcl_auto,    colormin:10,    bitseq:0,    pmemory:1,    gmkb:60,    pairt:180,    cmod:rgbcw,    slidemod:2,    micpin:23,    customcode:00ff,    rstbr:50,    ktime:5,    0err:70,    colormax:100,    c_pin:6,    module:CBU,    ctrl_lv:1,    rstmode:2,    irpin:26,    brightmax:100,    sfunc:1,    key_lv:0,    wfct:3,    pwmhz:1000 } Code: text Expand Select all Copy to clipboard Device configuration, as extracted from Tuya:  - Microphone (TODO) on P23 - LED Cool (Channel 4) on P6 - IR Receiver is on P26 - PWM Frequency 1000 Device seems to be using CBU module, which is using BK7231N.

So how did you configure the PixelAnim driver? What is your autoexec.bat?

snakesrules94 · Answer

hello, i didn't start yet to have colour leds. I'm just trying right now to have cool/warm white working. I have no autoexec.bat right now. BTW, i've also tried the esphome/libretiny port for this led strip and i also have no light at all, no white, no colours.

We need more information and you need to try the RGB. Maybe they have now alternate CW control, where second pin is used to control brightness. Try playing with GPIO Doctor on PWM pins. Make some detailed photos, what is connected where?

snakesrules94 · Answer

I think the game is over for now .. I don't have power any more to the board. I have 24V on input but the board is not powered, thinking something went wrong.The BK7231N is ok when powered directly from pin but not when powered from the 24V power supply.

Maybe it's just a mechanical damage. Can you check where voltage reaches and where it doesn't? How the step down converter looks like?

Dratii · Answer

Hello, I can relate to the snakesrules94 posts. Code: TextLog in, to see the code and Code: JSONLog in, to see the code and I can't get any LED's to light up

Can you share 2MB Tuya flash dump so I can try flashing it to my device and check the protocol on the scope?

Dratii · Answer

Okay no problem, if I understand correctly it's the file that the BK7231Flasher took as a backup so here it is

p.kaczmarek2 · Answer

Thank you, can you also share some photos of the device inside? Have you tried to run PixelAnim driver, as in the first post? Related guide:

Dratii · Answer

Here are the photos of the insides: and on the box there is .1 at the end of product code so i guess that means it's a new revision I didn't run PixelAnim driver because I have no clue what pins are relating to rgb led's and/or CW

p.kaczmarek2 · Answer

We actually know which pin is used for LED RGBs, the ones that are per-pixel addressable. It's always P16, hardware SPI output. That's because hardware SPI is used to control the WS2812 LEDs. For a start, I'd suggest following PixelAnim/WS2812 topic (linked few posts above) and trying to get some RGB light. I would also check if 24V is present on LEDs, because some devices might have extra pin used to toggle power on and off for them, sometimes to dim them. Check it with multimeter. Probably the transistor between 24 in and out is used: If there is 0V at output of transistor, try setting each pin in GPIODoctor to 1 and observe which enables voltage for the strip. It will be probably one of PWM pins.

Dratii · Answer

the 24V on the LED's is present but after using this RGB code in autoexec.bat form PixelAnim thread:Code: TextLog in, to see the codei didn't get any leds to light up and i tried toggling it on and off using the button in the home menu

For the people that have the revision of this product (3202086.2), here is my esphome config and the pinout that I figured out.

For those who has LSC 3202086.1 (i belive it is the same as of @Dratii), i modified config for esphome based on @xpeng config Here is how it looks Code: text Expand Select all Copy to clipboard bk72xx:   board: generic-bk7231n-qfn32-tuya light:   - platform: cwww     id: white_light     name: White Light     cold_white: output_cw     warm_white: output_ww     cold_white_color_temperature: 6500 K     warm_white_color_temperature: 2700 K     on_turn_on:       - light.turn_off: color_light   - platform: beken_spi_led_strip     id: color_light     name: Color Light     pin: P16     chipset: WS2812     num_leds: 40     rgb_order: RBG     power_supply: led_power     effects:      - random:      - pulse:      - strobe:      - flicker:      - addressable_rainbow:      - addressable_color_wipe:      - addressable_scan:      - addressable_twinkle:      - addressable_random_twinkle:      - addressable_fireworks:      - addressable_flicker:     on_turn_on:       - light.turn_off: white_light output:   - platform: libretiny_pwm     id: output_cw     pin: P6     power_supply: led_power   - platform: libretiny_pwm     id: output_ww     pin: P24     power_supply: led_power power_supply:     id: led_power     pin: P22 remote_receiver:   pin:     number: P26     mode:       input: true       pullup: true   dump: all binary_sensor:   - platform: gpio     pin:       number: P20       inverted: True       mode:         input: True         pullup: True     name: Button     on_press:       - light.toggle: white_light
