How can I get the speed (RPM) of the VI encoder
Greetings,
I have a two motors with quadrature encoders attached to them.
I use the VI encoder with the myRIO, which generates two values - counter value and the direction of the counter. The value of the counter, I try to display the speed (RPM). Only the value of the counter is count upwards or downwards according to the direction; I need a way to use these figures to measure the speed. I can't understand how to do this?
Thanks in advance for your help.

You have to count the difference in the values of a counter and divide to measurement period.
Not exactly, the result of the subtraction of counting must be divided by the number of counts of encoder/rotation before being divided by dt (expressed in minutes).

All my old tabs are missing after a crash. I chose "view my tabs, windows and last time ', like the start option. Many unwanted changes in tab management happened recently. For example when I close a tab in a window of the two tab, I see a blank screen (see picture). Preview display seems to be broken (see attachment). How can I get the old behaviour back?
After researching the issue, it seems that the problem was a problem of NoScript configuration. After restoring NoScript to the default values, the tab number disappeared.
Thanks for your help.
