Hi,
I recently came across the NI Measurement Hardware Driver Development Kit (MHDDK) and all of its associated documentation.
My problem is as follows:
When using RIO to communicate with my FlexRIO device, the latency is unacceptable to my clients (over 5 microseconds to send and receive small amounts of data <150 bytes)
Q: So I hope to develop my own drivers which will be optimized for such data transfers, and my question is,does anybody have any advice of what I should do?
Q: Does anybody know where I can find more documentation with regards to my PXI-7953R device? Such as how to use what register to do transfer data to write to a control...etc?
So far I have used NI-Spy to trap all calls made to my RIO device, unfortunately however, none of these functions are documented and I have been unable to reproduce the same results by using NI-VISA.
Thanks!
John
