-how about the protocol...should the master ask all the slaves if they have something to say, all the time?, over and over again ?
yes -or should the slaves start to talk when they have something to say? no -how can i be sure they don't start at the same time? see above - a slave is only allowed to 'speak' when 'asked' happy easter to you too Erik |
