Re: No detent rotary encoder

Jack, W8TEE

With a human turning the encoder shaft, I'm pretty sure that the Nano could easily keep up. However, I would think one with that granularity (i.e., 360 degrees / 400 steps per revolution = 0.9 degrees per move) would be a little fussy to use without modification to the software. Think about it. It's common to have a one detent move on a "detent" encoder to be associated with a 1KHz frequency change. Therefore a 9 degree rotation would cause a 9KHz change. Even if you were at the 40M band start (i.e., 7.0 MHz), a single revolution puts you at 7.4MHz; outside the band in the US. A minor software change can fix this, but I would think it would need to be changed or you would need to work with lower increments.

Thank you Jack

Maybe like this one:
but dont this have a high encoder rate (400) too high for the raduino code?
