unsigned short CO1553_utilCmdCreate | ( | unsigned short | rtAddr, | |
unsigned short | subAddr, | |||
unsigned short | wordCount, | |||
int | txFlag | |||
) |
Creates a 1553 command word.
Constructs a 1553 bus command word out of components. This function can be used to create both data transfer and mode code commands. The subAddr value should be '0' to indicate a mode code command. If the command is a regular data transfer command, then the wordCount value indicates the number of 16-bit data words in the message. If the command is a mode code command, then the wordCount value is the mode code.
rtAddr | The remote terminal address value. | |
subAddr | The subaddress value. | |
wordCount | The word count or mode code value. | |
txFlag | The transmit flag: 0 = RT receive, 1 = RT transmit. |

int CO1553_utilCmdGetTxFlag | ( | unsigned short | cmdWord | ) |
Gets the Tx flag value from a 1553 command word.
Determines if cmdWord represents a transmit or receive command. Remember that the direction is with respect to the remote terminal: transmit = RT->BC, receive = BC->RT.
