I can't see any reason why it wouldn't - it's just a generic GUI library used by hundreds of other Python projects...

Have you looked at https://wiki.python.org/moin/TkInter yet

...and there's been various projects posted on the blog over the years

GPIOs 14 and 15 are by default setup to be used as the UART pins, but they can also just be used as ordinary GPIO pins.
Each GPIO pin can be configured as an input, as an output, or as one of (up to) 6 ALT functions

I don't konw whether the picamera package has relations with system of pi. The system version as follows: pi@raspberrypi ~ $ uname -a Linux raspberrypi 3.10.25+ #616 PREEMPT Mon Dec 23 18:13:02 GMT 2013 armv6l GNU/Linux then i change to the newest system, the error disappeared and it runs ok! pi@ju...

The problem with the Foundation camera is not with image quality but the casing. Designing a camera head that works in all weather conditions is not an easy task. You have to use a proper lens, seal the camera unit, put a heater for fog elimination, use an IP67 case, etc. There is no need to reinve...

ShiftPlusOne works on that. The speed is one gigabit per second on two lanes So user ShiftPlusOne has something working? ShiftPlusOne is currently working for the RP Foundation, so has access to all the internal tools and secrets. But he obviously still has to stick to the Foundation's/Broadcom's N...

Haha, at least I didn't point you to lmgtfy.com

...and you can use software like H2testw to check if your SD card is fake or not.

It's a kingston 8Gb micro sdhc and was actually supplied with the rasberry pi itself about two weeks ago. Do you mean one of these cards? http://swag.raspberrypi.org/products/noobs-8gb-sd-card AFAIK they're all Samsung :? With USB SD card-readers being so cheap, maybe it wouldn't hurt to buy a newe...

Looking at your image, you've actually used NOOBS to install 3 separate operating systems onto your SD card. So it's not surprising that you've run out of space! You'll need to press SHIFT at power-on to access NOOBS's recovery menu, and then install *just* the OS you want to use. But doing so will ...

As far as the software on the Pi is concerned, there's absolutely no difference between the 'regular' Raspberry Pi camera and the NoIR Raspberry Pi camera (the Pi can't even tell the difference!). So all the tutorials about using V4L with the regular Pi camera will work just as well with the Pi NoIR...

Lots of places sell "Raspberry Pi starter kits" and there are hundreds and hundreds of Raspberry Pi tutorials available online.
All depends which areas you want to learn...

AndrewS

Odd. Perhaps it's your monitor that is getting "confused" though and not your Raspberry Pi? (I guess you could try unplugging and replugging the HDMI cable in both the "correct" and "wrong" display situations and see if that makes any difference?) Why do you need to set such a strange resolution? Ma...

IMHO if you're "new on Raspeberry Pi world" you'll find things much easier if you start out with Raspbian, as there's much more help / instructions / tutorials available for it. Have a go at developing your project with it, and you can always then migrate it to ArchLinux later if you need a bit of a...

AndrewS

Any reason to use pg.ptime.time() rather than the more commonly used time.time() ? I guess you could have 'import time' as the first line of your program, and then (using time.time) you'd be able to time how long it takes to do the other imports? And as well as timing the individual sections, it's p...

Is that page supposed to say "Materials: Philippine Mahogany, Brass" ?

AndrewS

However in that case, why are you using a USB A socket (which is used by host devices, i.e. the ones normally supplying the power) rather than a USB B socket (which is used by slave devices, i.e. the ones normally consuming the power) :?: No reason really other than I guess that I happened to have ...

When people say "Excel sheets" they often just mean CSV files which Python has built-in support for

And it's worth looking also at http://www.raspberrypi.org/documentation/usage/ and http://www.raspberrypi.org/community/
but especially http://www.themagpi.com/
