I'm not sure I love how this was implemented, but RGB_BUILTIN has co-opted the previous use of LED_BUILTIN, specifically to make it easier to use the Arduino HIGH/LOW functionality. The code for neoPixelWrite is part of arduino-esp32 core- RGB_BUILTIN is not going to work as an RGB with any 3rd ...

Quick update: Looking through the open issues, I found some of the information in https://github.com/espressif/arduino-esp32/issues/7767

RGB_BUILTIN works fine with the function: neopixelWrite

I also found that if I run the sketch:
#include "Freenove_WS2812_Lib_for_ESP32.h"

#define LEDS_COUNT 1 ...

I have been experimenting with seeing if the Arduino debugger works with a few of the different ESP32 boards, and thought I would experiment with just cycling the colors of the built in RGB led... But each time I changed from (C3 to S2 or S3), I kept having to remember to change the #define for ...

Wondering if it is possible to use a CMIS-DAP board to debug an ESP32-S2 board using the Arduino IDE 2.x IDE?
The only JTAG options I see are: Disabled, FTDI Adapter, ESP USB Bridge.

Disabled : I am assuming means no JTAG...

FTDI Adapter : If I build for it, The GDB Server tab shows it failed ...
