I have a problem when i use the AI_Vread function. It appears to me that the i need to initialise my daq card before it can start to pick up the readings from my voltage source. Please advise me!!!
You can refer to one of the shipping NI-DAQ examples code. For your case, I believe you can look at the one named "AIOnePoint.c"; which can be found at C:\Program Files\National Instruments\NI-DAQ\Examples\VisualC\AI. Hope this helps. Filipe
