Just as the title says the esp becomes unresponsive after some time. The web interface stops responding and the leds freeze. trouble shooting wise I have tried:
switched 12v powersupply.
Removing all leds.
Swithed what pin I use for led data.
Using an external 3.3v regulator.
Put a capacitor on the 5v led power or/and the esp32 3.3v power.
Put a 470 ohm resistor between the led and the esp on the data line.
Done all of the above on both a esp32 modemcu devkit v1 and an esp32 WROOM module.
the setup I’m trying to achieve is using a WS2812B led to boost the signal to an WS2815 strip with 594 leds on it. I’m using buck regulators to step down 12v to 5v and 3.3v.
