#137906 - master slave PC performance Responding to: ???'s previous message |
-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 something like this?: while(system_is_up) { for (i=1;i<number_of_uC;i++) do you have something to say? if (yes) { process the data } } that will take a lot of processor time... wouldn't it ? Is that ok in terms of performance ? |
