I'm new to this forum, so hello everybody. I am also not sure if this is in the right place so please advise if not.
I have been looking round for a while for an answer to this and haven't been able to find anything, I'm sure somebody will have done it.
My question is I want to be able to use Ethernet and serial comms simultaneously.
I currently have an arduino Uno with an Ethernet shield so I can control it from my laptop or phone. All this bit works great, have spend ages writing the code and the app. It is for an arduino controlled brewery. When it is finished I will post all about it.
I have a flowmeter, working as a counter so I can monitor water usage, which uses interrupts. while i have all the other code and libraries installed for the rest of the brewery it just doesn't work. The code works really well when it is stand alone.
So I want to be able to then have a second arduino connected to the first over serial so I can send a few commands and receive the calculated volume every 10 seconds or so.
I know that the Ethernet uses the SPI bus so is this even possible? I have a mega with multiple serial ports for this very purpose, but wanted to get somebody else's view before I started tearing my hair out.
Any thoughts?
Cheers
