Trigger Byte on produce

My First time in using the trigger byte option on producing CAN messages - what value do i place in this byte to produce a single transmit? does it need to be incremented? or is it a state change? or can i just toggle the value of bit 0?

It is a state change. You can either toggle or increment the bit.

Thanks for the answer, presume it can be any of the 8 bits? and to be clear: it will send the message as the bit goes high, will it send again when the bit goes low?

Yes.

Correct.

Any change will work, but it is most common to implement it by increasing the value +1, so it also works as a counter, but it’s not necessary.
