Take max, min, averages speed of motor?

[ha noi]

Exp: I have to conect Pc with motor, and pc read the speed of motor in 10min. Maybe there are 3,4 measurements (it's not constant) in each min. How can I read the max, min, averages  of speed in each min?

Hi ha noi,

there are functions to calc min, max and mean...
You only have to collect the data for each minute of measurement in separate arrays.
Or use shift registers (in your measurement loop) to collect the values. When a new minute has started you calc your results from collected data and clear the shift registers before wiring new values.
