Configuring and installing firmware

The firmware has to be configured for a particular e-skate. At the very least, the information about the wheel size, gearing, and the battery pack has to be provided.

1. Open the Arduino IDE.
2. Install the TFT_22_ILI9225 library.
   • Open the Arduino IDE and do Tools > Manage Libraries... , in this dialog search for TFT_22_ILI9225 and install it.
3. Download Roxie firmware from releases and unzip to your Arduino project directory (typically $HOME/Documents/Arduino/).
4. Open the roxie.ino from Arduino IDE to load the project.
5. Go to the roxie_config.h tab and adjust the configuration to your needs.
6. Connect Roxie to your computer using a micro-usb cable.
7. Under Tools, select:
   • Board: Arduino Nano Every
   • Port: the port to which the arduino was attached
8. Upload.
