If you find the driver is not installed automatically after plugging into the device, you can install it manually: click to download the CH340 driver program (https://www.dfrobot.com.cn/images/upload/File/DFR0489/201709061014334z925t.zip). Set Arduino IDE Development Environment Plug FireBeetle to your computer, install the driver manually. Add FireBeetle Board URL to Arduino IDE Open Arduino IDE, File->Preferences, find Additional Boards Manager URLs, copy the below link, and paste in the blank. http://download.dfrobot.top/FireBeetle/package_esp32_index.json (http://download.dfrobot.top/FireBeetle/package_esp32_index.json) File->Preferences paste url here Click OK Open Tools->Board->Boards Manager, waiting automatic update. You'll find FireBeetle-ESP32 Now, the development environment has been installed, you can use it like a normal Arduino board. Sample Code - Blink The default LED for Beetle Board-ESP32 is D9, input following code: // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(D9, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(D9, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(D9, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second FAQ Q&A Some general Arduino Problems/FAQ/Tips A For any questions, advice or cool ideas to share, please visit the DFRobot Forum (https://www.dfrobot.com/forum/).
