tracestick

Read more about tracestick at the main site!

Getting Started (Arduino)

  1. Follow modified instructions from the M5Stack website, the reference instructions are for M5Stack Core, we are working on M5Stick, there is a difference. Ignoring this difference will cause your M5Stick to become unresponsive.
  2. Install Arduino IDE - Download Windows Installer instead of the ZIP file for non-admin install
  3. Install M5Stick Library from our repo instead of that provided by m5stack.
    • This is also how you would update the library whenever there are breaking changes.
    • Windows:
      • Copy the 'M5StickC' folder into your 'Documents\Arduino\libraries\' folder
    • OSX:
      • [a little similar to Windows, let us know if someone tried it out]
  4. Skip the factory and Hello World test.
  5. Checkout our git repo for code: https://github.com/bettr-xyz/tracestick-firmware.
    • git checkout https://github.com/bettr-xyz/tracestick-firmware.git
    • Current code is in /alpha.
  6. Copy the BLE library from our repo and replace yours:
  7. Install the ArduinoJson library
    • Tools > Manage Libraries > Search for ArduinoJson > Install ArduinoJson Library
  8. Before you upload ANY code, open and ensure that Arduino is set to
    • Board: M5Stick-C
    • Partition Scheme: No OTA (Large App) Arduino Settings
