I encountered a problem While runing my program. Namely program shows error message:'invalid driver handle failed' then hangs up.
In a brief. Program is supposed to send every 15 ms an impulse via digital output of advantech card (card im trying to communicate with). Impulse range is 1 to 2 ms. Basis of servo control.
Problem has something to do with Timer. when event is assigned to Timer - problem occurs.
I cannot attach program files, guess i can send that only individually.
