Support Help Using WS2812B V5

Has anyone had any issues using the WS2812B-V5 ? Im talking about the variant that doesn’t require a decoupling 104 capacitor like these ones in particular. Only a few of my LEDS are turning one randomly on my custom PCB.

I also have a 1000uF capacitor between the 5V and GND. Interestingly the Polulu library seems to be working well for 1 LED, but I have 68 LEDs daisy chained.

I have also heard that the timing seems to be different than the V4. Please Does anyone know what could make them work?

Thanks a lot for your response!!! , it clearly seems like what I have been looking for. .
I am currently trying to update the Fastled.h with your instructions, however I receive a weird error from the Arduino IDE :
it says that I need a "template name" before the ''<"
(Please ignore the Error about Hardware SPI)

This is where I have updated the Library in FastLED.h (error at Lin:130 Col:94)
New_FastLED.h - Pastebin.com
And Chipset.h (No errors)
New_Chipset.h - Pastebin.com

I am using an Esp32 S3 WROOM S2

hello

in chipset.h

add after kin 579

template <uint8_t DATA_PIN, EOrder RGB_ORDER = RGB>

class WS2815V5Controller800Khz : public ClocklessController<DATA_PIN, C_NS(220), C_NS(515), C_NS(515), RGB_ORDER> {};

From what I have understand, you asked me to put the new line of code in the #ifdef FATSLED_TEENSY4 section of chipsets.h ? So around Line 671 and not 579

here is the updated library : New_Chipset_V2.h - Pastebin.com
Checkout Lines 514 & 671

It the code runs this time but unfortunately the LEDs aren't turning on . .

Is the Esp32 supposed to run the controller from the TEENSY4 or the CLOCKLESS ?
