Do the timers in i.MX6ULL can support quadrature (incremental) encoder input ?

Hi,

     We are evaluting the i.MX6ULL for our project.

     In the project, we need to encode one magnetic encoder quadrature input (A/B), and one signal output.

     We find i.MX6ULL has not QDC, so we consider that if the timer in i.mx6ull can support this function?

     Hope you can help to check with us.

     Thanks very much.

There is no QDC in i.MX6ULL. So the feature is not supported.

Hi Jimmychan,

      Get it. Thanks.

      Yes, i.MX6ULL hasn't QDC, so I conside that whether the quadrature encoder inputs can be captured by GPT capture function, but I still can't be sured about it.

      Do you have some tips for this ?

      Thanks.
