Config build and flash

This project uses the arduino-cli compiler to build & flash new firmware. Windows users also need Arduino IDE (tested with v1.8.15).

Usage - macOS and Linux

The script will verify if all needed libraries and the samd core is installed and install them if needed. If you prefer to do this step manually, follow the step in the next chapter.

For building the project:

• For audio support, use:

./arduino-build.sh --build

• For IMU sensor support, use:

./arduino-build.sh --build --with-imu

For flashing use:

./arduino-build.sh --flash

You can also do both by using:

./arduino-build.sh --all [--with-imu]

Usage - Windows

• Run update_libraries_windows.bat script to install Arduino libraries.

For building the project:

• For audio support, use:

./arduino-win-build.bat --build

• For IMU sensor support, use:

./arduino-win-build.bat --build --with-imu

For flashing use, put the board in boot mode (double click on the reset button when connecting the board to USB, while the orange LED is blinking. In boot mode you should see the red LED fading on and off):

./arduino-win-build.bat --flash

You can also do both by using:

./arduino-win-build.bat --all [--with-imu]

Setup Manually

• Install Board package SAMD v1.8.9

• Install following libraries using Arduino Library manager (use exact versions):

  • avdweb_SAMDtimer@1.0.0
  • Adafruit ZeroTimer Library@1.0.1
  • Adafruit BusIO@1.8.2
  • Adafruit GFX Library@1.10.10
  • Adafruit SSD1306@2.4.6
  • nicohood/HID-Project@2.6.1
  • SdFat@2.0.6

• Install the following libraries as a Zip library:

  • lib/Adafruit_ASFcore
  • lib/PMIC_SGM41512
  • lib/AudioUSB
  • lib/NDP
  • lib/NDP_utils
  • lib/SerialFlash
  • lib/syntiant_ilib

• Patch the Arduino USBCore driver: copy lib/Arduino USBCore driver/USBCore.cpp in SAMD package folder (ie: /Users/[USER]/Library/Arduino15/packages/arduino/hardware/samd/1.8.9/cores/arduino/USB/)
