I am using the example 'Read Dig Chan-Change Detection.vi' (from the DAQmx/Digital measurements examples) to detect changes on a single line of a PXI-6528.
When the system is waiting for the digital input to change, the CPU usage (viewed in task manager) sits at 100% - this seems to me to be excessive - I thought change detection was intended reduce CPU usage.
I'm using Labview 7.1, DAQmx 7.2, windows XP (SP2) on a 3GHz Xeon with 2GB of ram.
Is there a method of reducing the CPU usage with this function or should I abandon change detection.
