hi i'm talking of about 20 RPS on each revolution 360 pulse means about 7200 pulse per second by searching i found a solution hope to be suitable in my situation QUOTE any information of how to do this ?

Hi all ,, Im new to lab view , i'm currently using it for my graduation project (controlling gasoline engine using lab view) , my problem now is to utilize an encoder to perform specified tasks upon certian degrees , so i used loop that get the current degree from the encoder then perform the tasks upon specified conditions, the problem that the encoder frequency is higher than loop iteration frequency (i think that) for examlple i did an equality comparison with certain degree number then i found for low RPM it invoke the associated equality task but for heigher RPM it doesnt. so i thaught if the loop iteration frequency can be raised ? or can i make my tasks pulse driven ? i meant perform the tasks upon each pulse come from the encoder (instead of using loop) Thanks
