The firmware is the part of the software flashed to the ATMega328 on the EduBuzzers. It capable of both serving as a buzzer and being a base station. | The firmware is the part of the software flashed to the ATMega328 on the EduBuzzers.

It is written in C (technically, C++, although hardly any C++ is used). It uses the [http://www.nongnu.org/avr-libc/ avr-libc], [http://jeelabs.net/projects/cafe/repository/show/RF12 JeeLabs' RF12 library] and [http://www.pjrc.com/teensy/td_libs_OneWire.html Paul Stoffregen's OneWire library].

(if you flash on an arduino uno, replace "duemilanove328" with "uno"; you might need to adapt the device name as well). The installation routine will be different if you use another way of flashing than flashing an ATMega sitting inside an Arduino; consult your flasher's operating instructions in that case. | (if you flash on an arduino uno, replace "duemilanove328" with "uno"; you might need to adapt the device name as well).

== | When using ATMegas that don't originate from Arduinos, we nevertheless recommend [http://arduino.cc/en/Tutorial/ArduinoISP|to flash the Arduino firmware] there, including their fuse settings. | ||

The MAC address of the device and its configured base station are stored in the first 2x8 byte of the EEPROM memory. They can be configured from [[HSC2011/Software/Ygor|from Ygor]] or using the [[HSC2011/Communication/Serial protocol|M01-M05 commands]] on the serial console. | |||
