Energy Monitor – part 2
So, now I hopefully(!) have my cable which will give me access to the UART RX of the CC128 energy monitor. Time to try it out and begin processing some data with it!
Firstly, I go to the XMOS website and get the UART code and play around with it to create the UART code I want (RX only at the moment), compile it and give it a run.
But it's never that simple! All I get are null characters. Odd I think - so I recheck the wiring, recheck the code. All seems to be ok.
Energy Monitor – Part 1
My energy monitor arrived today! It's working well - I was slightly worried about how good the reception would be for the transmitter, but I am pleasantly surprised that even with the receiver 3 floors above the transmitter it seems to register a good signal.
But that's boring - time to start hacking!
So, first thing I need is the interface cable. The back of the unit has a handy RJ45 connector that has serial in it (see my initial energy monitoring post). This needs connecting to my XC-3 kit so that I can begin to get the data out of it. So time to get the soldering iron out!
