Function Documentation

unsigned int Pbc_CommInit (  void   )

Initialize 1553 boot communications. Configures 1553 communications for use during primary boot. The 1553 driver is initialized and started in a subroutine, though, so it can be retried repeatedly in the polling loop if it fails here. Returns: MSG code.

Here is the call graph for this function:

unsigned int Pbc_CommPoll (  const unsigned int  buf_bytes, void *  buf_p, unsigned int *  cmd_bytes )

Poll the 1553 interface for commands or telemetry. See if there is a command ready on the 1553 interface or if it is time to transmit another telemetry packet. Command receipt is indicated by setting the return parameter cmd_bytes to a non-zero value. Parameters: buf_bytes  (in) Size, in bytes, of command receive buffer. buf_p  (in) Pointer to buffer to receive command. cmd_bytes  (out) Size, in bytes, of command received. Returns: MSG code.

Here is the call graph for this function:

void Pbc_CommShutdown (  void   )

Shutdown 1553 boot communications. Shuts down boot 1553 communications in preparation for secondary boot. Returns: Nothing.

const char* Pbc_CommType (  void   )

Identify communication interface (SIU or EPU). Returns a string that identifies the type of boot communication interface that is in use (SIU or EPU). Returns: Pointer to an identification string.
