*   
*   \brief 
* Program main features:
*    - enables communication via ethernet
*    - reads data from GY-80 sensor
*    - reads data from built-in touch sensor
*    - enables configuration of Wiz550io ethernet card via PC serial port
*  
* 
* Peripherals connection details:
*
* WIZ550io pins are connected to:
*    - MOSI  ->  PTD2
*    - MISO  ->  PTD3
*    - SCLK  ->  PTD1
*    - CS    ->  PTD0
*    - RST   ->  PTA20
*    - VCC   ->  +3.3V
*    - GND   ->  GND
*    
* IMU GY-80 pins:
*    - VCC   ->  +5V
*    - GND   ->  GND
*    - SDA   ->  PTC9
*    - SCL   ->  PTC8
*    - Connection to other I2C port may not work!!!
*    
* Serial port communication is available via virtual OpenSDA COM port.
* Detailed description about configuring OpenSDA available here: https://mbed.org/handbook/Windows-serial-configuration .
*
* Digital I/O ports pins and names:
*   - PTE20  ->  P1
*   - PTE21  ->  P2
*   - PTE22  ->  P3
*   - PTE23  ->  P4
*   - PTE29  ->  P5
*   - PTE30  ->  P6
*
* Ethernet commands:
* Available commands:
*   - "read_sensor" - reads all sensor data - Reply form: "Sensor data: magnX, magnY, magnZ, accelX, accelY, accelZ, gyroX, gyroY, gyroZ, TSIposition"
*   - "check_ports" - reads ports P1 to P6 status - Reply form: "Port values: P1: %d, P2: %d, P3: %d, P4: %d, P5: %d, P6: %d"
* Single port commands:
*   - "set_P$_i" - sets port as input    - Reply: "P1 is now set as input"
*   - "set_P$_o" - sets port as output   - Reply: "P1 is now set as output"
*   - "set_P$_1" - sets port as 1 (High) - Reply: "P1 value is now: %d "
*   - "set_P$_0" - sets port as 0 (low)  - Reply: "P1 value is now: %d " 
*   - "get_P$"   - gets port value       - Reply: "P1 value: %d"
*   -  $ mark is port number from 1-6
