Re: No key hook

Can you take us back a stage or two with more information? Is this a brand-new 'out of the box' RPi being booted for the first time? Or is it an established system that you have recently modified? What Operating System are you booting? Was it installed directly from an image file, or via the NOOBS i...

Re: Bringing rasberry pi to China

According to a recent blog post from the Raspberry Pi Foundation the Raspberry Pi is well known and available in China. If there is any difficulty taking yours with you it looks as though it would be easy to get one while you are there.

Re: Trouble flashing

Perhaps hinting that you tell us the source of the file was too subtle? So I Googled for Xbian. From the main page at http://www.xbian.org I clicked on the orange button [[Download XBian]] and got a 404 Not Found page. Not very comforting. But I'm resilient... Used the Menu button on the main page, ...

Re: Trouble flashing

Two quick things to add to this saga. Firstly. If you are using Win32DiskImager to 'flash' an SD card image then using SDFormatter beforehand is probably redundant. It won't do any harm but it is unlikely to do anything to help. Secondly. What is the source of the supposed .img file (for Xbian) that...

Re: remote commands made easy

Thanks for sharing.

You might like to point out that this depends on Pyro4, and that the version of pyro that is installable from the standard Raspbian repositories is v3.14

There is a link to Pyro4 here.

Re: beginner

At some time in the last 30 months everyone was a beginner with the RaspberryPi.

There is a lot of basic material on the RaspberryPi's own official site here. Once you have looked at a few of those resources you may be able to ask some more detailed or focussed questions if you still need help.

Re: Has anyone used a Rand Mcnally GPS for a display?

The User Manual only refers to an optional camera. It doesn't say that it takes standard composite video input: although that seems to be the most obvious choice, they might have chosen some proprietary scheme to lock you into buying their own camera add-on module?

If you and your collaborators have written all that code then you clearly know far more about python and network programming than I do, so I have nothing to add.

Is it accurate to describe your venture as the world's first Full HD LCD add-on? The display described at http://hdmipi.com/ , which has already been funded by a completed Kickstarter campaign , also appears to be an HD LCD display for the RPi. There is no reason why there should not be choice and c...

Not in general. I do all my experimenting over a network using ssh, and have never had any issues with using GPIO connections that could be related to the network.
