<div dir="ltr">So it turns out, i had a usb bub II (had to disable my electric monitor so it can't stay) so I booted one of these guys up today. Below is my basic output. (i used putty for the serial connection, on windows, i came up as com6. Arduino worked too, putty is just an older friend).<div>
typing against the console didn't seem to give output. </div><div><br></div><div>When I pushed buttons and twiddled the dial... i got output!</div><div><div>=F0%@24C1;T0 12 W255 0 F255 0 W255 0 F255 0;S10 10 21 cffO</div>
</div><div><br></div><div><br></div><div>I am guessing that is 24C but i am pretty lost after that. Do we have a guide to what those are? Or what I should be doing next? I powered up another one but buttons, etc didn't seem to relay. presumably i need to sync them somehow. I'm all ears for suggestions. I will dig through the code if necessary but some pointers to relevant parts would be great.</div>
<div><br></div><div>as an aside on power, I am using USB power, it is 5v rather than the 3 specified in teh other mail but the usb connector was too tempting not to try. is there a risk of burning the board?</div><div><br>

My tinkering kit arrived a few hours ago.<br>
<br>
FTDI cable has been ordered.<br>
<br>
I have 3 questions right now. (I have some more that I'll either figure out<br>
in the next few days, or I'll ask at a suitable time).<br>
<br>
1. Please confirm the connections that should be soldered. Damon wrote<br>
"solder to it's normally-open contacts which are the near-centre lug and<br>
the one further from it, marked 'C'." I THINK that means that I solder red<br>
& black to the left & centre pins in the attached image (the white cable is<br>
marked "ANT", and is I suppose the antenna?)<br>
<br>
2. How should I power the two boards? Hopefully the image can help here;<br>
the green terminals are marked 5 / B / GND / 3.3, but I don't believe<br>
you've passed on any information about this issue.<br>
<br>
3. Do I *need* an Arduino now, or *might* I need one in the future (to<br>
reprogram the board?) If possible, I hope to use my Debian desktop PC to<br>
connect to the board(s). I've read the Ubuntu section at<br>
<a href="http://sourceforge.net/p/opentrv/wiki/Arduino/" target="_blank">http://sourceforge.net/p/opentrv/wiki/Arduino/</a> and already installed<br>
arduino and arduino-core, but I'm still not clear if this is going to talk<br>
to the Arduino or to the OpenTRV controller board.<br>
<br>
