The LED(circled in red below) on FireBeetle 2 ESP32-E is default to be connected to pin 2/D9. Now make it blink by programming. Sample Code: The on-board LED blinks at an interval of 1 second. int ledPin = D9; //Define LED pin void setup(){ pinMode(ledPin, OUTPUT);// Set...
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...

When uploaded, the orange LED on the XIAO ESP32S3 will blink. You can use this UF2 file as a test. Step 5: Re-enter UF2 BootLoader Mode If you need to re-enter UF2 BootLoader mode to upload another UF2 file, quickly press the Reset button followed by the Boot button. There’s ...
I didn't try the examples until after I did the upgrades. There is no LED onboard to blink. I connected a couple external resistors and LEDs to GPIO pins and added blink functions to my code. The LEDs blink so I am sure the board is working as it should....
