<div>Dan, </div>
<div> </div>
<div>Congratulations on getting your partition to recognize the full 8 gig!</div>
<div> </div>
<div>Not only that, you got the ftpd to compile. Sorry about minicom not compiling. Hell, I'm surprised they made a gcc port small enough yet it compiles stuff at all.<br></div>
<div>Ah... and you have to rebuild everything all over again on the Chumby. Well, at least you have practice now. You're going to be the local expert on that device pretty soon. Take notes for us if you can :)</div>
<div> </div>
<div>I still think it's a bit adventurous to be considering using WiFi for the communications between the Chumby and the S2, if that's what you're doing. Serial is so... ancient... and simple.. and all you need is a little cable between them. Of course, I have no experience with the Propeller, so everything sounds easy to me if I'm clueless about it.</div>
<div> </div>
<div>Remember, if you go WiFi, you're going to need not just the hardware on the S2, but also the TCP/IP software stack, and some WiFi implementation (firmware?) not to mention know how to write programs that pass information over sockets.</div>
<div> </div>
<div>Ah, I didn't see that BST toolset. Why do you need the source? <br></div>

<div>Dan, </div>
<div> </div>
<div>As far as controlling the S2 with the Chumby goes, I already mentioned that I'd be tempted to just use serial port communications.</div>
<div> </div>
<div>They do have code available for this purpose:</div>
<div> </div>
<div>Simple serial:</div>
<div><a href="http://obex.parallax.com/objects/183/" rel="nofollow" target="_blank">http://obex.parallax.com/objects/183/</a></div>
<div> </div>
<div>and Full Duplex Serial:</div>
<div><a href="http://obex.parallax.com/objects/54/" rel="nofollow" target="_blank">http://obex.parallax.com/objects/54/</a></div>
<div> </div>
<div>It would then be a matter of using one of those libraries to make a (rather short) program to handshake between the two devices.</div>
<div> </div>
<div>Does your S2 really have WiFi? If it does, well, it's a tough call whether or not WiFi is the way to go. I'm just throwing out options.</div>
<div> </div>
<div>However you do it, I'd probably keep things simple by having the Chumby accept a huge 'status word' which describes everything going on with all of the S2 devices at any time, and then a 'command word' which the Chumby could yell at the S2 which would tell it what to do with any of its devices at any time. That's just a personal preference on how I'd design it.</div>
<div> </div></div>
<div>
<div class="im">
<div>I guess that GUI tool for installing the code on the propeller only works on Windows, but someone (as usual) is developing an IDE for Linux: </div></div>
<div>
<div class="im"><a href="http://propeller.wikispaces.com/Linux+Development" rel="nofollow" target="_blank">http://propeller.wikispaces.com/Linux+Development</a><br><br></div>I didn't know about that one, I'll have a closer look at it.<br>
</div>
<div class="im">
<div> </div>
<div>Getting serial communications to function on the Chumby will probably be less involved; it actually is a real computer with an OS.</div></div></div>
<div class="im">
<div> </div>
<div>Also, you mentioned that you installed gcc on the Chumby. Did you test it by trying to compile anything yet?</div></div>
<div><br>I used the latest source code release of pure-ftpd, it compiled just like on any regular linux box. It was cool to have an ftp server running right on the chumby.<br>I tried to compile minicom but gcc complained about a mess of errors and quite.<br>
<br>But now I need to reinstall everything again after fixing a weird partitioning problem caused by how chumby does things. Now I can use all of the 8gb card I'm now using <br> </div></div>-dan<br></blockquote></td>
