Quadrature Encoder Velocity Measurement

RegulaTor — Tue, 28 Oct 2025 15:38:31 GMT

Hi,

I am trying to figure out how to use a timer to improve low speed quadrature encoder measurements on i.MX RT1060. I can see in the reference manual (55.4.2 Prescaler for Slow or Fast Speed Measurement) that there should be some support for low speed measurements using a timer. However, I am having a hard time understanding how I can set this up? Are the some examples since this was posted?

If not could you provide a brief explanation of what I need to do? Does the ENC have its own timer or should I setup a separate timer? What are the steps for setting up such a timer?

Thanks!

Best regards,

Tor

Hello @RegulaTor ,

Yes, we have such kind of demo but it is just internal used, would you please raise a private case for it? Please kindly refer to https://www.nxp.com/video/tutorial-for-nxp-support-case-portal:NCP-VIDEO for details.

Have a great day,
Kan
