hello,
I an new in LabVIEW FPGA programing so I would appreciate any help. I am using sb-rio 9636 card and optocoupler for speed messaurment of DC motor. I have conected everyting right and the sensor is giving me date. But messauring the speed the oscilations of sensor data are huge. I am not changing the speed and motor continiousliy is rotating in the same speed but data are not the same. For example im 12 V that is the max speed motor schould rotate in 6500 rpm/min but in one second it is showing 6500 and in the other 5500 rpm/min. think that there is not problem in the code but that the messaurment are not reliable. I will put my code. I need to know is there anz other way to do encoder readings.
Thank you
