Configuration and management of SPIRIT Basic packets.

This module can be used to manage the configuration of Spirit Basic packets. The user can obtain a packet configuration filling the structure PktBasicInit, defining in it some general parameters for the Spirit Basic packet format. Another structure the user can fill is PktBasicAddressesInit to define the addresses which will be used during the communication. Moreover, functions to set the payload length and the destination address are provided.

Example:

 PktBasicInit basicInit={
   PKT_PREAMBLE_LENGTH_08BYTES,       // preamble length in bytes
   PKT_SYNC_LENGTH_4BYTES,            // sync word length in bytes
   0x1A2635A8,                        // sync word
   PKT_LENGTH_VAR,                    // variable or fixed payload length
   7,                                 // length field width in bits (used only for variable length)
   PKT_NO_CRC,                        // CRC mode
   PKT_CONTROL_LENGTH_0BYTES,         // control field length
   S_ENABLE,                          // address field
   S_DISABLE,                         // FEC
   S_ENABLE                           // whitening
 };

 PktBasicAddressesInit addressInit={
   S_ENABLE,                          // enable/disable filtering on my address
   0x34,                              // my address (address of the current node)
   S_DISABLE,                         // enable/disable filtering on multicast address
   0xEE,                              // multicast address
   S_DISABLE,                         // enable/disable filtering on broadcast address
   0xFF                               // broadcast address
 };

 ...

 SpiritPktBasicInit(&basicInit);
 SpiritPktBasicAddressesInit(&addressInit);

 ...

 SpiritPktBasicSetPayloadLength(20);
 SpiritPktBasicSetDestinationAddress(0x44);

 ...

The module provides some other functions that can be used to modify or read only some configuration parameters.
