Running multiple encoders with QDEC library

[Faws]

Hello!

I was just wondering if it is possible to use multiple encoders at once with the QDEC driver? Can you initialize multiple encoders on different pins or do you have to alternatively uninitialize one before initializing another one on different pins?

Thank you.

Hi Filip

The QDEC peripheral only supports one decoder at a time. 

If you need to support multiple decoders you either need to uninitialize and reinitialize the QDEC as you say, or implement one decoder using the QDEC and another using other methods (such as configuring the GPIOTE to generate interrupts on pin changes, and decode the signals manually in the interrupt handler).
