PID = SUPPORTED_PARAMTERS / PARAMTER_DESCRIPTION question

[berntd]

Hello all,

Thanks for this. Those are the exact issues I have come up with here.

If DMX_START_ADDRESS is supported (because the device needs it then how is a controller supposed to know this unless it can detect it with the PARAMTER PIDs?

I would have to agree with Scott in that it should be treated as a NON mandatory pid and thus included in the SUPPORTED_PARAMTER -list.


Then again, one could argue that if the device does
not need DMX_START_ADDRESS, it should respond with a nack reason NR_UNKNOWN_PID.
The controller could then make a conclusion from that, in which case Peter's approach will work too.

Hmm...

Kind regards
Bernt
