According to the Arduino website: “The Arduino IDE 2.0 is an improvement of the classic IDE, with increased performance, improved user interface and many new features, such as autocompletion, a built-in debugger and syncing sketches with Arduino Cloud“. If you want to install the ESP32 bo...
It also comes with a built-in blue LED that is internally connected to GPIO 2. This LED is useful for debugging to give some sort of visual physical output. There’s also a red LED that lights up when you provide power to the board. ESP32 GPIOs Pinout Guide The ESP32 chip comes wi...
Step3:选择 ESP32C3 Dev Module 作为开发板,使用示例文件中的“ESP32”-“GPIO”-“BlinkRGB” 测试板载 RGB 的测试情况。其余使用方法与 Arduino 其他开发板均一致。 /* BlinkRGB Demonstrates usage of onboard RGB LED on some ESP dev boards. Calling digitalWrite(RGB_BUILTIN, HIGH) will use hidden RG...
