For those new to message boards please try to follow a few simple rules when posting your question.
Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
Im currently making an app on windows forms trying to program a micro over UART. I can achieve it, although it is taking a long time to carry out the program. I have used stopwatches to determine it is my read function taking up the majority of the time. When i try to read the micros response from each command I have to wait for all of it, which is why im using a while loop in the code below, if the returned message size is not what i expect. What im wondering is, if there is any way to speed up this process. The response from the micro should be pretty fast, its running at a baudrate of 115200, meaning the whole 512 kb file should in theory take just over 30 seconds to complete, at the moment it is more than double that, at 80 seconds.
I have an OV2710 based USB camera (a low-light, as it should go inside a closed box). It is a UVC camera so no need for driver...
Connected the camera to a Win10 laptop - disturbing green shaded image (not fatal but all white/light colors are get greenish)
Connected to a Fedore 31 desktop - same...
Connected to a RPi 2/3/4 using a touchscreen - got a green-only shaded image... The image is clear and fast but green-only...
Anyone has experience with these kind of cameras? I just want to know if there is a way to fix that or should start to search for other camera (any suggestion to that direction is also welcome)..

I have a new PC, only a few months old. HP Envy Desktop 795 64bit running Windows 10 Pro.
Within the past month or so I am noticing what I can only describe seems to be USB interruptions. Every few minutes the Mouse and Keyboard 'freeze' up. If I'm watching a video it pauses for a second. It happens 2 or 3 times over a few seconds, then doesn't happen again for a dew minutes.
I'm not a hardware guy so I'm in the dark on this. I can provide any additional info if needed.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
There has been a requirement to use Gemalto PC PIN Pad device in unsecured mode, Secure Pin Entry (SPE) not active. We have been trying our best to search online for any hint but unfortunately no luck yet. We can't contact Gemalto support because of no formal purchase of device yet (we are in R&D/evaluation phase) as Gemalto is requesting device information formally.
Any hint would be greatly appreciated.

Some PCIe devices cannot read more than 4 GB of address space without an additional driver or modified driver. In such cases, what limits how much memory they can read? Is it the memory controller? Is it the firmware of the PCIe device? Or is it something else? I don't think it is because of the device driver itself because PCIe devices can read or write to RAM without a driver. Someone said it is a 32-bit vs 64-bit issue but I do not understand why PCIe device can only address 32-bit.
I have purchased an ST8000NM0075 as this drive is compatible with my SAN system. However, this drive shipped with E001 firmware on it and I need it to run the LE OEM firmware from lenovo for this drive to work. I have been unable to find a way to flash the LE firmware onto a drive with E firmware. Is there anything I can do to make this work?
I am looking for ideas or even solutions to access the video or image stream of BOA SPOT cameras from Teledyne DALSA directly for further image processing. Teledyne has a SDK which unfortunately does no support this series of cameras. Only their pre-built software solution gives access but cant be integrated in other programs.
So far I didn't find any SDK or solution which does not rely on theis Sapera SDK (which doesn't support BOA)
Been there, done that. They want to sell (more expensive) cameras which are supported by their SDK, not the other way round. Yet we cant just tell our customers "sorry, got to buy new cameras because the old one is the same but it has no official support"
Good day pals! Please I have been curious about this since I studied Computer Science. How can I build a hardware and control this hardware via my vb.net, c# or c++ application designed by me?
I know this question is vast but I only need guidelines on how to go about it probably the right keywords to use in searching please

Sorry, I don't want to use existing board. I want to build my own hardware from scratch. I can build the hardware cos I have knowledge but don't know how to communicate the hardware with software I have designed in any of the language
