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
My first thought would be a bad power supply. If you're brave enough to open the case of the supply and not shock yourself on a charged cap, look for bulging capacitors in it.
It's also possible your motherboard may have a bad VRM stage or bad caps there too. Eletrolytic caps on a motherboard are not common any more. They tended to last about 5 years whereas the polymer caps that replaced them last for about 20+ years.
I used [STM32F407] to write a network port program, and the connection with the host computer can sometimes be connected, sometimes not connected.
Connected normally with the F7 board. So it is a software problem. Please help me find a master
I want two atmega32s to communicate in a 1000-foot range, so I decided to use a serial line. I know that rs232 is not a good way to communicate in this wide range, so I decided to use RS485 which is a balanced pair. To do this, I want to use a MAX485 chip like this.
What the program basically does is that an atmega sends "Paresh" on the serial port, another atmega receives it, and if it does receive "Paresh" then it issues a strcmp which emits "Mathur". If the first atmega receives "Mathur", it sends paresh again and continues to loop.
After several cycles of debugging, I received a strange string. what should I do? Why can't I use RS485 communication for my design purposes. Long-distance communication through the serial port.
How to solve the ADS1230 temperature? Is it related to offset calibration?The 16 bits are taken as the two bits change with temperature. Is it related to offset calibration? Calibrated before AD starts? Or calibrated after AD startup?
I used the original scale hardware to include the 1230 and the sensor and power 3.3V circuit. The original connected MCU is disconnected, and only three control lines and ground lines are connected. When the temperature rises, the number of readings increases. It is basically unchanged in a short time (about 1-2 hours) at normal temperature. Is this situation a warm performance? How to solve? The original scale has been very stable.
I used the ADS1230 to do the bridge pressure signal acquisition, and I also encountered similar problems.
You can add corrections that must be corrected for each use, each time you correct the zero point, manual correction and zero offset correction. A DC offset can be added to the signal input of the circuit, but debugging is a bit cumbersome; it is also possible to add an offset value to the result of the AD conversion, which can be done by software.
How to correct, this is my processing conversion function

I have a 1TB drive that is partitioned into to 2 500GM partitions, C: and E:. I want to remove the E: parition. It it possible to unpartition it and merge the unparitioned space into C: without wiping my drive?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
Not totally sure, but I have done the reverse without problems. I have a 1Tb drive which was partitioned as all C:, and I repartitioned it so that it is now 720Gb C: and 280Gb raw, which I use for Linux. The repartitioning did not have any effect on Windows.
