Hello WeberClass,

WEber>>I have 200 pic 16f84a chips.I want to communicate them (200 pic
16f84a chips) on the same line . Communication speed isn't important. At
the same time it can read or write.
I must write commands in pic basic pro.<<

We can help you, but we need more info...


Are you going one master CPU, and 199 Slaves? Or are they
goin to be all masters, with the ability to communicate to all?

with the Serin Serout commands, you have a wait until a certain sequence of characters come across. With this command, you can achieve your goal.
