Function Documentation

void BSET (  unsigned    txRate )  [static]

The BSET application main task entry function. After initializing resources, the BSET() task function runs forever, listening on the BSET_rateSock socket for a new rate command word. Once received, the bit sync library function BSYNC_configure() is called to set the new bit rate in hardware. Parameters: txRate  The initial telemetry rate in bits / sec.

void BSET_exit (  int    signal )  [static]

Cleanup resources for BSET application. This function peforms the following actions to cleanup the BSET application after operation: Closes the BSET_rateSock. Calles exit() to stop the BSET() task. This function is called when signal SIGTERM is sent to task BSET(). Parameters: signal  Ignored.

int BSET_init (  void    )  [static]

Initialize resources for BSET application. This function peforms the following actions to setup the BSET application for operation: Creates the BSET_rateSock UDP socket. Binds BSET_rateSock to port BSET_RATE_PORT. Attaches the BSET_exit() function to the SIGTERM signal for the the BSET application task. Return values: 0  Success. -1  Failure because a resource could not be created or initialized.

int BSET_start (  int    taskPri, int    stackSize, unsigned    txRate )

Start the BSET application running. Starts the BSET() task running. Parameters: taskPri  The priority of the BIU application task. taskStack  The stack size of the BIU application task. txRate  The initial telemetry rate in bits / sec. Return values: 0  Success. -1  Failure.
