Ethernet over HDMI, sadly not supported by the Pi.

With libudev you don't list usb's you get notified on connect, disconnect events.

This is what you asked for:

I am working on a project that requires detecting if a new Usb storage has been pluged in.

There's a udev library for python.

That means the package has incomplete dependencies.
This should be fixed by the package maintainer.

Another thing that i recently learnt was that the data pins of many chargers and powerbanks have certain amout of resistance in them that allow them to be a "smart" charger. Basically they detect the voltage on the d+ and d- pins that tells them the device and then supply the power accordingly, idk...

If you load the driver as a module with modprobe, you can give the module options like which pins to use. Of course the driver has to support that. If you use a current kernel with devicetree and the driver supports devicetree, it might be as simple as giving the correct dt-parm in config.txt. Regar...

Which tool gives this error?
I suspect somebody complains that the partition type in the partition table is not the same as the actually formatted file system.

Great little computer

I was like Ohhh, I want one .... Doh, no camera connector

Would have been ideal for a security camera.
It could have been kept unpopulated on the bottom side.

Capacitive touch screens often have a problem with water on the surface, meaning the touch recognition gets screwed up. e.g. the capacitive touch pad of my laptop works really badly when used with a wet finger tip that makes a wet trace. Might not be well suited for a motorcycle. Or at least you sho...

PS also the micro SD Card that I am using is a SanDisk Ultra 32 GB Micro SD HC I This is your "problem". High capacity cards are usually formatted with exFAT. The raspberry needs a FAT16/32 partition to boot from. The partition label is irrelevant. The bootloader loos for the first patition on the ...

Thanks

Yes it is. Just as the GPU firmware on your PC is closed source.

The device tree is always board specific. It replaces the board configuration file from before device tre was a thing.
The device tree describes what device (internal to the SOC or external) is connected to what pin/register and so on.

Physically, yes it's possible. Normally you'd just use other GPIOs as CE pins for your display. The problem here will be to convince the driver to use the correct pins. I'm not sure if the CE is handled by the HW SPI controller on the Pi. For example on the AVR based arduinos you do have a hardware ...

As a BTW, can anyone tell me why the Raspberry PSU is fitted with a micro USB plug. when the board itself has the full size socket? particularly when the necessary adaptor is about as rare as hen's teeth. I'd value some opinions on this. I'm no newbie in all this. Before I retired I'd spent nine ye...

It may be possible to port FreeDOS to the raspberry, but what would you do with it? There's no DOS programs able to run on arm.

Somewhat related question: Are the RPi inputs schmitt triggered? If not you might burn the inputs by keeping them in the "forbidden area" for longer periods of time.

I have two ups's I use and have tried them with various mico sd cards. I have brought down the 1.4.1 noobs and will try it, but not to be negative I somehow feel a .001 change will not help at all. ;>} Thanks for the response. roly If your SD card had a pre B+ version of NOOBS then it will miss the...

If you have an android phone you can try this as hotspot as well. Maybe your router is doing something strange that the raspberry cannot cope with.

Hmm. You mean in the top right corner of the GUI? Nope nothing like that. Just the networks status icon, volume, CPU usage, clock and eject button. EDIT: Did the reading and know now that the rainbow square is the under voltage warning in the terminal screen. Answer is still nope. Nothing like that...

Aydan

Yes one of those is mine. As I said originally I can see the list of available networks, including mine, from the desktop. But when I plug in my key and hit OK nothing happens. And I've also tried setting this up in the conf file too and still nothing. Did you try with ethernet disconnected? Regard...

Did you actually enable the camera via e.g. raspi config?

It's a Windows bug. Windows built in unzipper can't handle the Jessie zip file because the output is larger than 4GB. What you need to do is install 7Zip (from http://www.7-zip.org/). It will "just work". tommygoessing is not talking about unzipping, but downloading. @tommygoessing: what do you use...

I can do python programming, But less of an expert. Thanks

Then have a look at Kivy. It's a python framework for touch interaction and more.

Aydan

You might have to wait a bit before mounting, because the device might not be ready yet. If I remember correctly, udev triggers before actually creating the device node. You should still not use SDxy notation to determine which device is which. Using the actual partition label makes sense. The parti...

Aydan

Since you want to use the touch screen, Kivy should be the best solution.
