command librairy

This homemade librairy implements hihg level functions to operate the open-seismic harware

All functions needs a stream object, wich is the serial port you want to use to send command.

All function use a command object to transfer data:

typedef int commandType;
typedef int commandDef;

typedef struct {
    commandType type;
    commandDef  def;
    int        status;
    int         adcConfig;
    String        data;
    int        workerId;
    bool        empty;
} command;

This allows to have different command object depending on the communication needs.

The buildAndSendCommand function send all the parameters in the command struct object with a letters before each parameter. This makes it easy to decode the information in the readCommand function.

When the master wants to harvest the data from a slave the it send a command asking for data. The slaves writes the data directly into the serial port while the master is ready to listen.
