 @page pgUracoliIntro Introduction

 @section secOverview Overview

 @uracoli provides libraries, example code and applications for
 use on different platforms with Atmels 8-bit-AVR-microcontrollers
 and IEEE 802.15.4 radio transceivers AT86RF{230,231,212} as well
 as ATmega128RFA1.

 @uracoli provides the following software components:

  - @ref grpLibRadio "Radio Library"\n
    The @RadioLib provides functions at two abstraction levels,
    (1) a set of basic functions for low level control
        of the radio transceiver, e.g. register read/write,
        frame buffer r/w, ... and
    (2) a set of high layer functions, e.g. transmit_frame()
        or set_radio_channel().
  - @ref grpLibIoutil "IoUtil Library"\n
    The @IoLib provides utility functions that
    are usefull in a embedded applications, like
    UART communication and timer functions as well as general
    purpose IO control (LEDs, keys, one wire bus).
    However, the @IoLib is @b not used by the @RadioLib, so
    it is just used for completion of the examples and applications.
    So the @IoLib can be used in own applications but this is not mandatory.
  - @ref pgXmplMain "Examples"\n
    These simple mini applications are used to,
    illustrate the use of the library functions. The examples
    can be used as starting point for the own applications.
  - @ref pgAppMain "Applications"\n
    This standalone radio applications are
    generic tools that can be used
    out of the box, like a wireless UART.
  - @ref pgContribMain "Contributions"\n
    Here is demontsrated, how embedded @uracoli radio applications
    are interfaced with PC applications, e.g. with Wireshark, Arduino,
    or a wireless bootloader application.

 @section secGetStarted Getting Started

 Before you can start, you need to install some software.

 First at all you will need a working AVR toolchain.
 The GNU AVR tools (or WinAVR on Windows) are used for compiling the firmware.
 The programs avrdude, avarice, avr-gdb (or AVR-Studio on Windows) are used to
 flash and debug the compiled applications.

 Additionally you probably want to install the python programming
 language with a version before @bv3.0 with the module pyserial in
 order to easily run and create PC applications that interact over
 the serial port with a radio module.

 If you want to build all libraries and applications
 from scratch, scons is needed. Building the documentation
 requires doxygen and graphviz.

 Some more detailed information about installing the software can be
 found at http://uracoli.nongnu.org/gettingstarted.html.

 Beside the software, two or more of the supported radio modules
 (see @ref pgBoards) are needed.

 In order to flash the compiled firmware into the micro controller,
 an hardware programmer like AVRISP, JTAGICE mkII, AVR-Dragon
 or a similiar tool is needed.
