Re: I2C programming

I've been trying hard to find a C paradigm for i2c and DS16xx sensors, so thank you. The topic's title is kind of insufficient. I've had DS1631 workin...

Re: Dimentions

It has been asked sooooo many times!!!!
Use the search!!!!

The final dimensions are not published, simply because the layout hasn\'t finalized yet.
They will be available when the final layout is.

I think we should create a Wiki somewhere for the Rpi PLC project to gather all information.

Re: LXDE, XFCE or just a plain window manager?

I would go with LXDE. Beautifull, clean and has low mem requirements for the stuff it provides. Well it's GTK though (more of a KDE/Qt guy myself), however I believe it could fit both Model B and A with moderate packages installed.
