Using your badge
Loading new apps
Charging
The badge charges via a microUSB socket, and takes about 2-3 hours for a full charge. The red charge LED next to the USB connector will extinguish when charging is complete
Hacking your badge
Upon connecting the badge to a computer, it should appear as a mass storage device, and a virtual serial port. Windows will require a driver file for the serial port, which is stored on the badge's mass storage. See here for full instructions.
All of the python code which runs on the badge can be modified on the mass storage device, and new apps can be added this way too. Be careful when using text editors to modify files on the device, if the mass storage is not 'safely removed' before removal, corruption of the file being edited can occur. If something goes wrong, the badge can be reset to its out-of-the-box state, so do not be concerned about breaking anything (although you may want copies of any code you are editing on your computer, in case something goes wrong)
To interactively run code on the badge, a python REPL can be accessed via the virtual serial port. Once you have found the serial port, use your favourite serial terminal to connect to the badge. Since the badge will be running the main software, press Ctrl+c to stop it, and the badge will display '>>>' to indicate it is ready to receive commands.
The badge runs micropython, and as a result does not contain everything you may expect from full python. See the micropython docs for more information. The LCD, WiFi and IMU drivers are specific to the EMF badge, so documentation about these peripherals are available on their respective pages.
