ref. How to use Arduino Boards as DAPLink Device

  • Seeed_Arduino_DAPLink -> Code -> Download ZIP -> Seeed_Arduino_DAPLink-master .zip

  • Open the Arduino IDE, and click sketch -> Include Library -> Add .ZIP Library, and choose Downloads/Seeed_Arduino_DAPLink-master.zip

Install the Adafruit_TinyUSB_Arduino Library

Note

If you have an error caused Adafruit_TinyUSB_Library when uploading sketch to Xiao, Use Adafruit_TinyUSB_Library Version 0.10.5 .

  • Open the Arduino IDE, and click sketch -> Include Library -> Add .ZIP Library, and choose Downloads/Adafruit_TinyUSB_Arduino-master.zip

Setup Xiao in Arduino

  • Preference -> Additional Boards Manager URLs https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json

  • Tool -> Boards -> Boards manager -> Search Xiao

  • Install Seeed SAMD Boards

Open the sketch

  • Unzip Seeed_Arduino_DAPLink-master.zip
  • Open Seeed_Arduino_DAPLink-master/examples/simple_daplink/simple_daplink.ino

Upload the sketch to Xiao

  • Upload the sketch to Xiao
    • LEDs on Xiao one green -> two blue
