NI6224 Analog In Driver

[lorenze]

I coded an RTX driver following the flow in example aiex1.cpp. 

What changes are needed to setup for single ended common ground, instead of differential?  Is it necessary to have a voltage present on the 6224 during integration testing?

After initialization the JOINT_STATUS_2 returns 0x90 indicating that AI_Scan_In_Progress_St, and AI_EOC_St.

Since NI doesn't provide a manual I have no idea what this means, except that these flags never clear.  Can't read from the FIFO unless the AI_Scan_In_Progress_St clears.  So where is the FIFO data?

Hey lorenze,

Thanks for contacting National Instruments support. This is actually a DDK question and there is a special forum for those questions that are answered by R&D, please post this question there.
