Hi,
Yes... of course. You can attach a debugger to Windows 10 from Windows 7 or greater.

Good morning~
I met some troubles about interrupting when programming the PIC18F87K22. This is the datasheet of PIC18F87K22:<url=<a href="http://www.kynix.com/uploadfiles/pdf65976/PIC18F87K22-I2fPT_606726.pdf">[^]> My situations are as following :
1). When using timer 3 to produce square ware (135Hz 270Hz),it require that the high need to compare first.I don’t know how to explain it clearly...
2)The receive of series port interrupted,the data that receiving host computer sent is <fs+9999>.
3)The INO is interrupted by surface.
4) The timer5 times about 1H.
5) Sometimes the numbers will lost when receiving data.However, it can’t lost when closing other interrupt.
Can you tell me how to solve this problems ?
Thank you very much.
Have a nice day~

My computer shop currently has 5 developers and we all are very frustrated with the performance of our workstations. We are trying to get management to go for some top-end workstations for blazing speed when we compile our applications in Visual Studio 2010 (yes we are behind) as well as fast speed with our SQL Server. We support one huge solution that takes 12 minutes to do a Rebuild-All on an i7 M620 (2 core) with 8GB RAM. That same solution takes 4 mins 10 secs on an i5 6500 (4 core) with 8GB of RAM.
We also would like to be able to build Virtual Machines on our workstations to create sandboxes for various development and pre-implementation tasks. There are a couple of build specs we are looking at requesting. Both are similar and only differ on CPU. I would like feedback on which we should go with and get best bang for the buck and achieve our blazing fast performance requirement. I will also mention that running BitLocker full disk encryption is a mandatory company requirement. We would love to get that build time down to 1 minute or less.
Build 1:
CPU: Intel I7 6900K (8 Core)
RAM: 32 GB DDR4
Primary HD: PCIe Solid State Drive (512GB)
Secondary HD: SATA Solid State Drive (500GB)
Build 2:
CPU: Intel i7 7700K (4 Core)
RAM: 32 GB DDR4
Primary HD: PCIe Solid State Drive (512GB)
Secondary HD: SATA Solid State Drive (500GB)
Installed Applications:
Visual Studio 2010
SQL Server 2008R2
BitLocker Full Disk Encryption
VMWare (Multiple VM Machines)
Possibly will try running RAM Drive for temp file usage in Visual Studio
Any feedback on these specs would be greatly appreciated? The managers that make the hardware purchase decisions for our organization says why do you need 32 GB of RAM, that's way over kill and you don't need that powerful of CPUs either.
Do you think 32 GB is overkill like our Hardware management is saying as push back? Do you agree that the i7 6900K or the 7700K is overkill for what I described as our goals? They are really pushing for the entire organization to use one model which is a very small footprint HP EliteDesk 800 mini with the i5 6500 and 8GB RAM. So we are lumped in with everyone else who just uses their computer for emails, spreadsheets and Word. Thoughts? Would you recommend something different as a Visual Studio Developer?

I just wanted to add one thought to speeding up your machines. If you can put two SSD's in a RAID 0 configuration, that will speed things up more than you can imagine.
And you yourself have found your argument against the "32 GB is overkill" point of view: They are lumping you in with people who need only minimal specs to get their job done.
The difficult we do right away...
...the impossible takes slightly longer.

Yes. I would also ask for an argumentation of "Hardware Management", just to see if it is a pushback.
I'm currently on a i3 (laptop cpu) with 16Gb; that may sound slow, but thanks to SSD it works quite speedy. Booting in seconds, launching VS in seconds. Good enough to Warcraft

Doesn't bring much additional speed, unless your HD is really slow. With Windows memory management the entire ram-disk may be pushed into virtual memory if the system needs space. It also does not speed up compiling that much.

Log the time that you are waiting for the compile to complete, and express that value in money (time * your costs). That way you have a financial argument, something that managers are sensitive to.

Yes.
It is unlikely that your Visual Studio project will utilize this much RAM. I have only encountered a few projects that utilize this much RAM... all of them were C++ solutions with 20+ projects/libs and the RAM was used only during the linking stage.
I would recommend Build 1 with only 16GB of RAM. More cores means faster compiling... and with SSD drives you get faster machine code generation on disk.
For running Virtual Machines... Build 1 is also vastly superior due to the large 20MB cpu cache versus the 8MB cache on the consumer processor.
They could save over $500 by avoiding the Intel I7 6900K and going for a lower-end Xeon 8 core processor with 20MB cache. There are dozens of them for under $500.

Hi everybody!
I got a second-hand Pioneer DVR-K17A (a slim burner with IDE interface for my laptop) and I managed to dump the firmware in order to edit it.
I would like to increase the number of writable sectors in a DVD-5 by editing the hexadecimal code. Theoretically, in this way I would enable the overburning feature.
Using an hex editor, I even saw some interesting strings that could be suitable for being modified, but I need someone who perfectly knows this stuff.
I know this is just a minor tweak and I really like experimenting, since the burner's value is very low.
I could even upload the firmware file, if someone were interested.
So if someone has useful suggestions, please reply to this message, even just for recommending particular forums more focused on firmware modding of burners.

Hi
Our team of university engineering postgrads has undertaken a challenge to create from scratch a computer-connected tactile matrix touch pad meant to let blind people sense with their fingers shapes others can see.
Whereas we will eventually need to get the programming job done by professionals, we would like to get a feel of what making a usb connected controller device live.
We would greatly appreciate advice pointing us to the relevant online resources with regards to the following:
- the choice of the programming language - how controllers are programmed these days and which frameworks (if that is the right word) are best to be used
- the path to making the chosen framework implementable in a newly designed device - at which stage of the controller design is it supposed to take place
Greetings
Tom

Too easy for you guys? That's okay. I will do the research myself and would only ask for correcting me if I am wrong on something. I hope noone minds my using this thread as a note board and perhaps someone googling for similar information one day will find it useful.
Here is what I found overnight.
First of all, I was mistaken about python language. The key word here was "driver".
Windows will require a driver made using a Driver Development Kit to convert ascii sent by the device to the computer (this kind of programming may require putting windows into a virtual machine). The communication is actually going to be in two directions.
Now, I will need to find out how to make an electronic device capable of sending and receiving ascii.
Anyone, is that right so far?

Probably yes, but you need to do the R & D yourself to find out whether it works for what you want. This is really not an easy question to answer since there are so many variables. People here will try to help you with specific questions, but we cannot second guess what might happen in a project that does not yet exist outside of your brain.

Of course, thanks Richard very much for your help.
Like I said, this is an initial phase, but we want to get an outlook of what will be there to be done even as the lab team are working on the mechanics of movement. Therefore, I hope you do not mind me using this forum to verify our team's findings and assumptions. Forums is place where many ideas can get combined into new ones - and one can not always predict what the outcome will be.
Thus, may I use the forum to ask some further questions to a broader public?

Of course, but as mentioned in the link I gave you, please try to make your questions specific and detailed. Vague questions tend only to get vague answers.

I have a question concerning python - again, just to check.
Does the stage of the hardware design require taking into consideration the specific language planned to be used, f.e. python vs R?
If not at all, when is this decision to be taken? Is it that a matter of compatibility with the software that is going to talk with the device?

Are you building your own "controller"?
If not, the manufacturer / vendor will dictate what "language" / protocol the controller supports (e.g. MODBUS).
Then there's typically a "driver"; that is written in the "host" operating system's language (e.g. C; C++; Assembler).
Then there's the "application" that communicates with the "driver"; using just about any language that is compatible with the driver.
I would first familiarize myself with what is available / doable before "building from scratch".

I need to exchange some files between a small 8 bit computer and a PC. SD memory cards are accessed by a simple serial protocol and could easily interfaced by the old computer.
Implementing routines to read from a FAT file system would be much work. That's why I would like to use a much simpler file system. On the PC side I would need to write a program that can read and write that file system. In the end I will need low level access to the sectors of the SD card.
Does anybody know a Win32 or .Net library that can do that?
Update: There may be a hardware solution. This device[^] can be hooked up to the old computer's bus as an I/O port and can handle all details of reading or writing to a memory stick. That would eliminate the need to build a custom interface or write code for a specific file system.

I bought an identical monitor (ASUS MX279H 27" Full HD 1920x1080 IPS HDMI DVI VGA Frameless Monitor) to my current setup. Since I only had one DVI port on my computer, I bought an HDMI to DVI splitter per recommendation. Monitor 1 is visible alone. Monitor 2 is visible alone. Monitor 1 replicates to Monitor 2 after some shenanigans. Previously, it was defaulting to 600x480 resolution whenever Monitor 2 was connected, but it is behaving itself now. Unfortunately, I can't get it to recognize the other monitor as a separate monitor. The control panel shows 1 and 2, but if I try to detect 2, the screen either disappears completely on both or it tells me Not Detected and goes back to the 640x480 resolution until I unplug Monitor 2 and reboot again. I've checked all my drivers and everything is supposed to be up-to-date. I'm currently running Windows 10 and I've seen a lot of complaints online about dual monitors setup. Every solution online did not work for me. Any suggestions?

A splitter[^] is good only for screen duplication - it will not let the OS identify that you have two monitors. And as long as OS does not know it will not let you expand the desktop to two monitors...
Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.
