 *
 *     \section intro_lcd LCD Introduction
 *
 *  This Raven LCD Driver application software was designed for a user interface
 *  to the Contiki 6LoWPAN collaboration on board the ATmega3290p. The
 *  LCD functionality uses the binary command set described in the release notes.
 *  These binary commands can also be found in a list of main.h.
 *
 *     \section compile_lcd Compiling Raven LCD Driver
 *
 *  The Raven LCD Driver is located in /platforms/avr-ravenlcd but it is not a contiki platform.
 *  $make TARGET=avr-ravenlcd will not work! Build it using the AVR Studio project and WinAVR or
 *  in Linux/Windows cmd/Cygwin $make in that directory. The AVR Studio dependency folder will confuse
 *  additional makes, use $make CYG=1 to bypass /dep creation or do $rm -R dep as needed.
 *   The .h file dependencies will be lost, so also $make CYG=1 clean after modifying any of those.
 *
 *
 *     \section fuses_lcd Board fuse settings
 *
 *  The Raven LCD (3290p device) requires the proper fuse settings to function properly.
 *  They are automatically set when flashing the .elf file. When using a .hex file set them manually:
 *   -# Raven LCD (3290p device)
 *      -# Extended: <b>0xFF</b> (No Brown Out)
 *      -# High: <b>0x99</b> (JTAG and ISP enabled, No OCDEN or EEPROM saving required)
 *      -# Low: <b>0xE2</b> (Use Int RC OSC - Start-up Time:6CK + 65ms)
 *
 *     \section notes_lcd Operation Release Notes
 *
 *  After programming the Raven LCD 3290p with the proper image, you will be introduced to
 *  the menu in the picture below:
 *
 *     \image html contiki_menu_3290.jpg
 *
 *  Operating the menu requires that the matching command set has been programmed into
 *  the ATmega1284 application. This will allow the menu to communicate properly and control the
 *  Contiki 6LoWPAN applcation on the 1284p.
 *
 *  During normal operation, you will need to make note of these <b>IMPORTANT</b> operating instructions:
 *   -# <b>Temp Sensor</b> - The temperature sensor shares the same GPIO as the JTAG interface for the 3290p.
 *   This requires the JTAG feature to be <b>disabled</b> in order to have proper temperature readings.
 *   -# <b>Debug Menu</b> - The DEBUG menu setting is used to configure this JTAG feature.
 *      -# If the JTAG feature is enabled during a temperature reading attempt,
 *      the menu will signal a <b>caution</b> symbol to the user letting them know the JTAG
 *      feature needs to be disabled.
 *     \image html caution.gif
 *      -# The JTAG header may also need to be physically disconnected from any external
 *      programming/debugging device in order to obtain correct temperature readings.
 *      -# The software will disable JTAG in sleep/doze modes. If the JTAG connection fails during
 *       reprogramming with AVR Studio, "try again with external reset" to recover.
 *   -# <b>Temp Data</b> - Once the temperature reading is proper, the user can send this reading
 *   to the webserver for Sensor Reading Data (<b>Once</b> or <b>Auto</b>). The webserver will
 *   only update the html data when <b>refreshed</b>.
 *   -# <b>EXT_SUPL_SIG</b> - This signal connects the external supply voltage to ADC2 through a divider.
 *   Enabling MEASURE_ADC2 in temp.h causes it to be sampled and sent to the 1284p along
 *   with the temperature.
 *
 *   More information about the operation of the Raven with Contiki can be found in the contikiwiki at http://www.sics.se/~adam/wiki/index.php/Avr_Raven.

 *
 *     \section binary_lcd Binary Command Description
 *
 *  Using the binary commmand list described in main.h, the 3290p will contruct a binary
 *  command serial frame to control the 1284p. An example command frame is contructed below:
 *   -# <b>0x01,0x01,0x81,0x01,0x04</b> - Send Ping Request number 1 to 1284p
 *       -# <b>0x01</b> - Start of binary command frame
 *       -# <b>0x01</b> - Length of binary command payload
 *       -# <b>0x81</b> - Binary command SEND_PING
 *       -# <b>0x01</b> - Payload value (eg. ping Request number 1)
 *       -# <b>0x04</b> - End of binary command frame
 *
 *  The following commands are sent to the 1284p.
 *   -# <b>SEND_TEMP - (0x80)</b>
 *   -# <b>SEND_PING - (0x81)</b>
 *   -# <b>SEND_ADC2 - (0x82)</b>
 *   -# <b>SEND_SLEEP- (0x83)</b>
 *   -# <b>SEND_WAKE - (0x84)</b>
 *
 *  The following commands are received from the 1284p.
 *   -# <b>REPORT_PING      - (0xC0)</b>
 *   -# <b>REPORT_PING_BEEP - (0xC1)</b>
 *   -# <b>REPORT_TEXT_MSG  - (0xC2)</b>
 *   -# <b>REPORT_WAKE      - (0xC3)</b>
 *
 *     \section sleep_lcd Sleep and Doze
 *   -# The Raven draws 27 milliamps when the 3290p and 1284p are both running and the RF230 in receive mode.
 *   -# Sleeping the 3290p and LCD display drops this to 21 ma with no loss in contiki functionality.
 *   -# The RF230 radio draws 15.5/16.5/7.8/1.5/0.02 ma in Rx/Tx/PLL_ON/TRX_OFF/SLEEP states.
 *    It is controlled by contiki on the 1284p according to the selected MAC power protocols to obtain the
 *    bulk of power savings; however the 3290p menu can tell it to sleep unconditionally or in a doze cycle.
 *   -# Unconditional SLEEP requires pushing the joystick button for wakeup. Once awake the 3290p sends
 *    SEND_WAKE commands to the 1284p until it responds with a REPORT_WAKE. "WAIT 1284p" is displayed during this time.
 *    Current draw is 40 microamps.
 *   -# As configured, doze sleeps the 3290p for 5 seconds after telling 1284p to sleep for 4 seconds. The 3290p
 *    wakes briefly to send temperature and voltage to the 1284p (which should be awake at this time), then tells it to
 *    sleep again. Thus the 1284p will be active 20% of the time, although it may ignore the command to sleep
 *    if there are active TCP connections.  The 3290p energy usage is essentially zero in this mode; total savings will
 *    depend on actual 1284p wake time and radio usage. Alter the timings as desired, or comment out the 1284p sleep
 *    command to shut down only the 3290p in doze mode.
