Hello,

    I have a half duplex bus that i want to snif, i am building my own
sniffer, based on a PIC 16F628, but i am stuck with one problem, i am
not blocking, i am sniffing the bus to debug, so i don't know how
discern who is speaking on the bus (it is half duplex). Do you know how
to could i do on hardware to discern who is speaking on the bus, if the
master or the slave?

Thanks!
