I’m looking to buy some motors with quadrature encoders from you and I have a question.
I found a few DC motors/encoders (no datasheet) laying around that have a hall effect quadrature encoder attached. I tried using these but found they generated false interrupts when connected up to my MCU. I hooked up a scope and found the encoders were taking 7us to transition when the motor was running slowly (about 1 rev/sec) and there is a little sine wave “bump” in the middle of the transition.
So I’m wondering if this is normal for a Hall quadrature encoder? Or are yours of a different type that produce a quicker/cleaner digital output that would be more compatible with hooking to 3.3v MCU’s GPIO pins?
