Readout of more than 25 AI Channels with ANSI C library

[hbuentem]

Hi,
I want to readout all 32 AI channels from my NI 6224 using the DAQmxReadAnalogF64 function from the ANSI C library NIDAQmx.lib, with one function call. This works fine if only 25 channels are specified. When more as 25 channels are specified all data values are zero. Who can help ?? How to do ?

Dear hbuentem

Attached find a simple CVI project which implements sampling from all 32
AI channels of a PCI-6224 board (cp. screenshot).

Best regards
