Had some trouble with the ESP32U devkit boards I got on ebay.
It has a micro-usb adapter but after connecting it, no com port shows up in windows.
I tried using the boot button and also tying IO0 to gnd, still nothing.
Any idea why this is? I tried multiple cables, esp32u boards and different usb ...

Im using the WLED software

Thanks! I'll give it a shot
Last time I had a problem with one of the two WS2812b LED strips, it would have a very brief flicker of crazy colors every few seconds... the problem still persisted even after I replaced both the ESP controller and LED strip.
The WS2812b was connected to the ESP32 output ...

Well the wiring diagram is very specific, figured there was a reason.
After going through the datasheets...
The WS2813 (I think version A), shows : RGB Channel Constant Current = 16mA

The SN74AHCT125N Shows : Output clamp current = 20mA
Continuous output current = 25mA
Absolute maximum ratings ...

I am confused how to calculate the proper resistor needed for the data lines on two, 1-meter long WS2813 LED strips.
From the ESP32U I am connecting pins 17 & 19 to a SN74AHCT125N booster exactly as in the diagram.

What I cant find clarification on is how it says "Data ...

I'm running two LED strips, each 32 led's, one line is only 6" and the other is 24" from the ESP32.
I added a 370ohm resistor and it seems to be stable.
Im curious what you mean by decoupling capacitors, I have a 1,000uf on the 5v across the power supply.
Is this what you mean or am I missing ...

Yes I also tried the ESP32 on a 5v 1a and the WS2812 LED's on a 5v 6a with the grounds tied together.
Its has something to do with the signal from the ESP32.

I am trying to get WS2812 LED strips to work with the ESP32 but it keeps flickering like crazy.
The ESP32-Wroom, ESP32-S, ESP32-U all do the same thing, the LED's flicker different colors and brightness when they should be solid.
I am trying to test with only 15 LED's powered by 5vdc 1amp. The color ...

I can utilize FreeRTOS through ArduinoIDE?

Ok so I can continue to code in ArduinoIDE, but the one and only way to utilize FreeRTOS is by compiling through ESP-IDF?
