Hi Matt, thanks for your reply.<br>I seems that writing the C libraries would be the best option.<br>I have some programming experience in C, but I don't know where to start. I have never programmed a driver, but I would like to help.<br>
I understand that it would be something like translating the C++ libraries included in the arduino IDE to C, right ?<br><br>Hachi<br><br><div class="gmail_quote">2012/9/4 Matt Jadud <span dir="ltr"><<a href="mailto:matt@jadud.com" target="_blank">matt@jadud.com</a>></span><br>

</div>There are not, yet, probably because none of us own an ethernet shield.<br>
<br>
(I think that's true.)<br>
<br>
It is certainly *possible*. Within just a few small limitations<br>
(mostly limited to speed), we can do anything in occam-pi that can be<br>
done in C.<br>
<br>
Reading this page:<br>

<br>
and assuming you are working with that ethernet shield, the answer is<br>
that we have some work to do. Specifically, I don't think we (yet)<br>
have a SPI implementation written. This could be a good opportunity to<br>
work on one, however, which would give us library support for 1) SPI<br>
devices, and 2) specifically, this device.<br>
<br>
The other answer is "yes," we can embed C code into our runtime. This<br>
grows the size of the runtime for everyone (generally bad), and to<br>
embed "arduino" code specifically, we have to roll everything over to<br>
C++... which is messy, and has other problems associated with it.<br>
(And, again, it grows the VM.) So we could, but it is a rather bad<br>
path for us to go down at this point.<br>
<br>
As a dev group, we haven't been working very consistently of late,<br>
primarily due to moves between jobs, etc. Would there be interest in<br>
picking up some ethernet shields and putting together:<br>
<br>
1. A SPI library,<br>
2. An SD library, and<br>
3. An Ethernet library?<br>
<br>
The SD and Ethernet libraries would be very useful to me, certainly.<br>
And Hachi, you would (of course) be encouraged to join in that effort<br>
as well, if you were so inclined.<br>
<br>
Cheers,<br>
Matt<br>
