Be sure to start the encoder or it won't count. I spent an hour remembering this last night. . .

Encoder1->Start();

I test them by getting the value and printing to the console.

signed mouseXPosition = Encoder1->Get();

printf("MouseX %d\r\n", mouseXPosition);

You can view the console output by right right clicking on the connection to the cRIO and selecting Target Tools / Target Console. This will display all printed data until a reboot.
