Just for the heck of it. Try bumping down your SPI clock to 1Mhz.

Have you tried say a 10k resistor ?

Did you check the docs?

No. Some calls use more than others. For instance, I would never use printf without a minimum of 2048. But things like x+7*Y you can get away with 1024 with no problems. There is a function called uxTaskGetStackHighWaterMark you might want to check into. This way you may know how close to running ou...

try increasing your stack size for the task.

xTaskCreatePinnedToCore(
neoTrigger,
"TaskCore0",
4096,
NULL,
0,
&TaskCore0,
0); // this is the core where it will run

@ESP_Minatel, Though I agree with your points. My beef with Arduino is that it teaches new coders things that will only confuse them later if they move to how things are really done in the real world of embedded. There are no such things as setip(), loop(), Serial.print and so on. They get to comfor...

Probably gong to get slammed for saying this. IMHO esp32 Arduino is for non serious, mostly lazy people that just want to get something done super fast with minimal reading and learning. Basically copy others code and be done with it. ESP32-IDF is for the more serious where you can control every asp...

Have your tried the Flash Download Tool ?

How about using the LEDC (LED Controller) ?

I also don't see any WiFI or Bluetoooth connection showing up on a nearby phone or computer

you wont, you need to turn those on in code.
