Re: R-Pi video feed question.

R-Pi has no video-input capability. I've seen other forum threads mention that USB video-capture-devices are available, but I doubt the Pi would be able to cope with the bandwidth of 8 at once.

http://www.raspberrypi.org/documentatio ... gnguide.md has a note about component temperature ranges, but that obviously applies just to the Compute Module rather than the Model A/B/B+ Raspberry Pis.

Re: Pi and Mathematica`

Of course you may already have a USB keyboard and mouse you can re-use with the Pi. Or you could run the Pi 'headless' ;)

And more Mathematica resources can be found here.

Re: Unable to disable splash screen

RaTTuS is right - there's a few very early-stage parameters in config.txt that are read by bootcode.bin, and the rest (the majority) that are read by start.elf. On NOOBS bootcode.bin is loaded (at power-on) from /dev/mmcblk0p1, and start.elf is loaded from the boot partition of your OS (typically /d...

Re: Electrical specifications BCM2835

I think http://www.scribd.com/doc/101830961/GPIO-Pads-Control2 is the nearest there is (currently) to an official specification, but I don't know if it has all the info you're looking for. OTOH, with the Pi being so cheap would it hurt to just buy one or two and actually do some experimentation to s...

It's not quite what you're asking for, but an even easier solution might just be to run the first script in the background?

Re: GUI

I only had a quick scan through the code, but it looks like the update_lcd() function is the one you want to modify? I guess just underneath the LCD.message(msg) you need to add a function which also displays 'msg' on screen?

Re: B+ Camera is not detected (workaround available)

I think this one can be easily argued both ways too. In the end, it will probably be defined using a device tree file and industrial users will be able to configure the hardware to suit their needs that way. It seems to me that the override parameter has all use cases covered until then. I've just ...

I don't think that either is more correct, it's just used in different context. Since I'm checking the revision from the platform file itself... Oh yeah, I'd missed that one block of code was from a kernel module, and the other block of code was from the platform file! Whoops, mea culpa. Not sure I...

Re: Extremely low performance with external USB exfat HDD

Linux (especially on the Pi) always has slow read/write speeds to exFAT or NTFS filesystems, because they're implemented as user-mode filesystem drivers, rather than kernel-mode (because of the patents etc. Microsoft has on them). The 'fix' is to reformat your HDD with a Linux-native filesystem such...

It's impossible to know what might have gone 'wrong' on the card, so I'm afraid it's impossible to suggest how to 'fix' it, without reformatting it to a blank state and starting again from scratch :( (Or if you're an advanced user, you might want to have a play around with http://www.cgsecurity.org/...

Re: Events - remote management and reimage

I guess you might be able to 'abuse' the silentinstall feature of NOOBS to do this? Silent-install gets triggered when the card doesn't have a /dev/mmcblk0p5 partition (see here and here ), so in theory you might be able to have a script that automatically SSHes in to a running Pi unmounts the boot ...
