How to setup build environment on Mac OS X

Build yourself

Install the latest FTDI serial driver: http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_2_17.dmg
Install Arduino sources: https://arduino.googlecode.com/files/arduino-1.0.4-src.tar.gz
Install CrossPack for AVR Development (contains avrdude command and AVR cross-compiler): http://www.obdev.at/products/crosspack/index.html

Edit your environment $HOME/.bashrc to add the following lines:

  export ARDUINODIR=$HOME/arduino-1.0.4/
  export BOARD=fio

Download latest software: https://github.com/bidouilles/bGeigieNano/zipball/master

Build and upload the software:

  cp -r libraries $HOME/arduino-1.0.4/
  make
  make upload

From a terminal type the following commands,

to find which usb device the arduino is connected on (you should get something like /dev/tty.usbserial-A700eYeV)
```
  ls /dev/tty.usbserial*
```

to download the lastest firmware for Arduino Fio

  wget https://raw.github.com/bidouilles/bGeigieNano/master/bGeigieNano.hex

to upload the firmware to the Arduino Fio

  /usr/local/bin/avrdude -DV -p atmega328p -P /dev/tty.usbserial-A700eYeV -c arduino -b 57600 -U flash:w:bGeigieNano.hex:i
