Make timer methods in ev3.py work #50

Closed afgym-baeu closed 7 years ago

afgym-baeu commented 7 years ago

Old code did not work because for a type mismatch and wrong values. time.clock() referenced to a not well defined "processor time" which increases by approx 0.05 per second. Therefore time.time() should be used. A call to time.time() returns the system time as a float value in seconds. Documentation states that it may be very unprecise on some systems but it seems to work on the EV3.

Thanks! I rechecked the docs - time.clock() actually returns the time spend by the processor. This is quite confusing. In C clock_gettime() is the recommended way to measure time spans.
