Delphi and NIDAQ

[tombxx@my-deja.com]

Hi,
I am using Delphi and the NiDAQ DLL to control a AT-MIO-16DE-10
board, I can control the digital outputs and inputs, but we also need
to read AI channels, Does anybody have any examples (in C if
neccessary) of how to confiqure a AI channel. I have been using the
help but examples would be helpful.
I understand that triggering is not possible with this board, am I
right?
I am planning to use SCAN_Start to log multiple channels, but I am
unsure now to setup the channels, do I use Select_Signal?
I need to log at a rate of ~1ms for upto a second, I think I need
to use double bufferring, correct?

Thanks for any help

Tom,

You may be interested in viewing some examples that NI has on
www.natinst.com. For example, I found a Continuous Acquire to File AI
Example in C++ and other DAQ examples at

http://digital.natinst.com/explprog.nsf/web%2Flanguage?OpenView&Start=1&Count=500&Expand=11.1#11.1

Unfortunately, I could not find any AI examples under Delphi, but this
should help a bit...
