I'm trying to improve my understanding of how these things work so would appreciate it if anyone can help me.
I have managed to get communication going back and forth using XBees and 232 Explorer shields and am now looking at 485.
I went with a 232 shield for the XBee as it obviously does more than just connect the right pins to the D-Sub (I did try that first) but I don't really know what.
Now I'm looking at 485 comms I'm having trouble finding a current 485 shield, especially one that isn't very expensive.
Then I found this thread
Few years old but the last comment discusses a way that you can do 485 comms without a 485 chip which, I guess is what I'm also using on the Explorer board (but a 232 one obviously).
Does this mean there is a way for me to send and receive 232 from an XBee without a conversion chip / board? And the same for 485?
Has anyone on here done these things?
