The current firmware is written by clifford and chrysn and is currently capable of both being a buzzer and being a base station; the base station can control all the hardware in the buzzers and receive events. It can be checked out from [http://github.com/Metalab/hsc2011/tree/master/firmware the firmware part of the project repository].
During firmware development, a serial protocol was developed, which is documented [http://github.com/Metalab/hsc2011/blob/master/firmware/README.serialprotocol alongside the firmware].
Open issues are in descending priority:
* separate timeout arrays for login and event
* redirect messages for controlling the base station itself
* fine-tuning timing for re-sends and responses (may only need validation)
* melody api
* read/write commands for VM
* enhanced get/set status packages for VM
* reading battery status using new firmware
* reading RSSI state
* multicasts
* <del>removing arduino specific stuff to reduce resource usage</del> (not a priority unless resources become a real problem)

< HSC2011

The EduBuzzer has software run in three parts:

  • Firmware run on the ATMega controllers (for hardware control and radio communication)
    • The firmware can run additional code inside a virtual machine for tasks like LED fading, meldoy beeping or even autonomous games.
  • Middleware running natively on the computer (for serving the firmware, managing communication and for persistence)
  • A Frontend running in a web browser (containing the game logic itself)

The communication through the whole software is described in the communication documentation.

there will be different software components involved

there is a firmware on each device

there will be a hostsoftware (webserver) that runs on the pc/laptop

this webserver will provide a webinterface to the javascript application

there are positions open for

  • the webserver/serialcom (python) amir implements this job with java
  • the webfrontend application logic (javascript)
  • the webfrontent design (CSS)
  • firmware and protocoldesign (AVR)

PC server

There is a proof-of-concept implementation of a serial controller and a simple voting game for debugging purposes in the repository. It demonstrates that the firmware can also do logins, handle disconnected clients and respond to events.
