I want to use VB6 control USB-6501, but I can't find very detailed datasheet.
I can only find some simple examples. But there is no more detailed information.
For example, I want to know how to change the delay after the output of DAQmxWriteDigitalLines()?
If USB-6501 can't do this, what model should I use?
It seems that USB-6501 cannot set the frequency of the output signal.
It seems that the frequency is 1K, and I cannot change it !
USB-6501 needs to delay 2ms after sending a signal, which is TOO slow for me!
I want a product that only delays 2us after sending a signal.
