Not sure if this is the correct forum or should be in programming. Try here first so as to not cross post.
Setting device as TWI slave and enabling TWGCE means that the slave receives messages posted to its ID as well as any General Call message. My question, is there any way of knowing whether the received message was one or the other?
I want my slaves to have a priority in responding to a general call and not reply immediately in lieu of a response from a higher prioritized unit.
