This example is a variant of "Example_bc6.c" that uses CONDITION and CONDITION3 to apply MULTIPLE conditions to determine a branch. If the Service Request bit is set in the status word AND the first data word is 0x1234, then send a TX VECTOR WORD mode command.
This example program sets up a simple BC message list. It creates a list of three messages, 1-R-1-32 2-T-2-32, and 1-T-2-32 in a 20ms minor frame. This BC list runs until stopped by user input. The user can either display the data (or errors) for the 2-T-2-32 message or quit.
TWO CONDITIONAL blocks have been inserted after the 2-T-2-32 message. If we see the SERVICE REQUEST bit set in the status word from this message AND the first data word is 0x1234, then the BC branches to send 2-T-0-16 (TX VECTOR WORD mode command) before going on with the frame.
In order to test this, you need a bus analyzer (BusTools/1553) simulating RTs 1 and 2. Toggle the SR bit in the RT2 status word and set the first data word for RT2-TX-SA2 to 0x1234, then use the bus monitor to verify that the TX VECTOR WORD mode command is sent when the conditions are met.
