00004 *   \brief 
00005 * Program main features:
00006 *    - enables communication via ethernet
00007 *    - reads data from GY-80 sensor
00008 *    - reads data from built-in touch sensor
00009 *    - enables configuration of Wiz550io ethernet card via PC serial port
00010 *  
00011 * 
00012 * Peripherals connection details:
00013 *
00014 * WIZ550io pins are connected to:
00015 *    - MOSI  ->  PTD2
00016 *    - MISO  ->  PTD3
00017 *    - SCLK  ->  PTD1
00018 *    - CS    ->  PTD0
00019 *    - RST   ->  PTA20
00020 *    - VCC   ->  +3.3V
00021 *    - GND   ->  GND
00022 *    
00023 * IMU GY-80 pins:
00024 *    - VCC   ->  +5V
00025 *    - GND   ->  GND
00026 *    - SDA   ->  PTC9
00027 *    - SCL   ->  PTC8
00028 *    - Connection to other I2C port may not work!!!
00029 *    
00030 * Serial port communication is available via virtual OpenSDA COM port.
00031 * Detailed description about configuring OpenSDA available here: https://mbed.org/handbook/Windows-serial-configuration .
00032 *
00033 * Digital I/O ports pins and names:
00034 *   - PTE20  ->  P1
00035 *   - PTE21  ->  P2
00036 *   - PTE22  ->  P3
00037 *   - PTE23  ->  P4
00038 *   - PTE29  ->  P5
00039 *   - PTE30  ->  P6
00040 *
00041 * Ethernet commands:
00042 * Available commands:
00043 *   - "read_sensor" - reads all sensor data - Reply form: "Sensor data: magnX, magnY, magnZ, accelX, accelY, accelZ, gyroX, gyroY, gyroZ, TSIposition"
00044 *   - "check_ports" - reads ports P1 to P6 status - Reply form: "Port values: P1: %d, P2: %d, P3: %d, P4: %d, P5: %d, P6: %d"
00045 * Single port commands:
00046 *   - "set_P$_i" - sets port as input    - Reply: "P1 is now set as input"
00047 *   - "set_P$_o" - sets port as output   - Reply: "P1 is now set as output"
00048 *   - "set_P$_1" - sets port as 1 (High) - Reply: "P1 value is now: %d "
00049 *   - "set_P$_0" - sets port as 0 (low)  - Reply: "P1 value is now: %d " 
00050 *   - "get_P$"   - gets port value       - Reply: "P1 value: %d"
00051 *   -  $ mark is port number from 1-6
