Hey thanks for the info! I'm using the functionality built in to the ESP32 board library, but I actually figured out the problem and it turns out it has nothing to do with the LED or the library. My ESP board has PSRAM on it, and the PSRAM uses GPIOs 35 thru 37 so there was a conflict on GPIO 37 (I ...

I'm building a program using an ESP32-S3 dev board and have encountered a weird problem. In short, if I set GPIO 37 to output mode without doing digitalWrite(RGB_BUILTIN, HIGH) first and then call the neopixelWrite function, the chip reboots. Is this expected behavior? My program uses GPIOs 35 throu...

Hey... uh... never mind!

I realized what's going on... the board where the function works has "USB CDC" (or whatever it's called), and the board where the function doesn't work has a plan UART... that apparently doesn't support that function! Case closed.

Hello! I'm working on a couple of different projects using the ESP32 core and Arduino development environment. I have a lot of "Serial.println()" statements in my code for debugging, but the code also needs to work well without the serial monitor connected, and that can at times cause slowness as de...
