camparing encoder count

[zamjir]

hi

I am reading an encoder and counting the pulses, with a display value which updates every 100ms.

 After a certain interval, the encoder count stops incrementing.

How can I save the encoder count at one  instant and compare with the count after an interval passes(e.g. 1 second )  to determine when the count stops increasing?

make a ringbuffer with

a) a subvi see example somewhere in XY-Graph

b) a queue

c) if you have LV-RT using the RT-FIFO

another way is attached
