There is a strange question, used to do a data acquisition software under winxp system always can run normally, communication interface is to use the USB serial port, now replaced a new dell computer, installed winxp system, collection software as a result, communication is easy to crash, I don't know why, computer hardware update can cause communication problems? I have been to understand the software work under an operating system normally should not be a problem, this understanding is wrong? Please help to analysis analysis together,

It's hard to say, inferior, not fully tested software, with the change of the hardware may appear all sorts of problems,

Such as I have seen a person to write a piece of software, the delay code was made 1560000 0.1 second air circulation, he automatically assume that all people are as fast as his computer, learn often excavator to be programmers only meet program on your computer running over it, and never test, also do not follow any specification, then write the program all too clear,

CodePudding user response:

Learn excavator was born?

CodePudding user response:

DELL computers do have this problem, especially in communication, when buying a computer do the test well, our company have many times

CodePudding user response:

The main reason may be communication problems (hardware, interference or something), then process without you

CodePudding user response:

This program has been run on hundreds of computers, has been normal, now in the computer to appear problem, but now computers are with Windows 7, we installed winxp, drivers are looking for a long time to mount, don't know if because winxp system and new communication problems caused by the computer hardware is not compatible

Should not permit a problem, can the computer to a serial port turn USB device you have interference, lead to the problem of communication, packet loss, suggested that under the manual debugging software, see the specific is where there is a problem

CodePudding user response:

Could you drive not installed, or have a DLL unregistered,,, only a DELL computer? Try to get more, suggest single-step operation debugging code

CodePudding user response:

Most likely, is a question of DELL machine USB interface, pick USB devices, in good quality U turn seton try, or between U turn occurrences and host U mouth and a better quality of a Hub to try,

CodePudding user response:

Uninstalled, I put my winxp system installed Windows 7 system, try down communication normal now, but only turn the usb serial port driver download several version installed, can be used is 2006 version, the download of the new Windows 7 drivers don't act on,
