I bought 2 vex optical shaft encoders and received them the other day. I did some programming and I’m sure there’s nothing wrong with the programming.
The problem is, when I turn it on, it works fine, then few more time I turn it, the encoder starts reading off. There’s 90 “clicks” on the wheel right? Like I turn the wheel clockwise, then counter clockwise, and clock wise, it reads 1 off each time. How fast / slow does the optical shaft encoder read?
I think it’s the speed of my wheel, cause it’s going really slow. How slow can the optical shaft encoder read? Wheel is turning roughly 20rpm, and I need complete accuracy, down to the last click. Is there anyway to solve the problem?
I’ve checked the encoder several times and cleaned it with pressured air, switched different encoders several times, redid the the programming several times, comes up with the same problem.
“The Quadrature Shaft Encoder detects the rotation of an axle that passes through it. It has a resolution of 360 counts per revolution (2 count intervals), and can distinguish between clockwise and counterclockwise rotation.”
