GET RID OF OE, as said in my previous post there is no way it will work (reliably)
Erik Thanks everyone for the help. Erik, The hardware is already made in such a way that the OE lines are tied together. When you say "get rid of OE" does that mean that the OE line has to be disconnected or just ignored by software. If I just don't do anything with OE and just configure TX and RX line and use dip switches for distinguishing slaves from master, will the hardware work? I will use dip switch in binary 01,10 and 11 setting to identify the slave devices. The master will have dip switch 00. The master will communicate to slave based on dip switch setting. Please advice. Thanks in advance. |
