hii Denish,

As I told you that it was not my intense to make your msg in spam, but might be it was not my time so by mistake i did that as i show my own post from your id.

And I think you would not like to help me but its seem like that some how you want to take revenge and want tell me that dont use this forum and go away.

then ok i ll not post my problem here ,if you want so .And if i put then I reuest you to not give me solutions.

Have a nice day.

Thank you for giving me a good laugh this morning. The only thing I want from you is to tell the truth about what you are doing. Obviously, you are not using the IVI driver that you said you downloaded. If telling what you really did is one of the things you are used to struggling with, then that is a major problem you have to overcome.

That I already mensioned that I am designing powersupply from hameg (HMP4040) and its third party driver so I dowenloaded it from the hameg website that i posted in last attachment and i made all the changes which needed for seriel configuration and i also made changes regarding to changing the bytes but still i am facing same problem.

thats y now i m trying to use USB may be its work and i got my mistake that i posted my problem in running thread.sorry for that again.

now i come to know how to create new thread.

so in future this problem ll not be repeated.

thank you for helping.

You have never posted your driver. You posted some pictures of a block diagram and I am telling you it simply cannot be from what you claim you downloaded.

Select the new post option and attach the actual code you wrote or download the correct driver and use that. If you try to download the IVI driver again, you are on your own.
