Example LabWindows/CVI code for NI4351

[JAH]

Hi,

I'm using an NI4351 PCI DAQ card with the Ni435x driver and LabWindows/CVI v5.5 (on Windows 98) to measure temperature and voltage levels. Are there any simple tested code examples that I could download, which use the NI435x driver function NI435X_Check_and_Read(), called from an asynchronous timer for continous scan? There are no problems when I use MAX (so hardware problem is ruled out), but my code yields occasional random temperature reading errors (looks like data corruption to me). The NI435x_ functions return no errors. Can I use lower level C driver functions instead of NI435X_Check(), NI435X_Read(), or NI435X_Check_and_Read()? What does MAX use behind the scene? Of course, the MAX setup only scans the one channel, so maybe this is why it works correctly. I have to scan one temperature channel and six voltage channels though.

Many thanks,
John.
