红色LED :红色LED,在电路板上标记为#13 ,在某些操作期间亮起或闪烁(例如在引导加载程序中发出脉冲),并且可以通过代码进行控制。它在 CircuitPython 中为board.LED,在 Arduino 中为LED_BUILTIN或13。 RGB :RGB灯引用的是33号引脚,在电路板上标记为33。在 CircuitPython引导加载程序中,被用来当做状态指示灯。通过代...

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 (...
