Permitted pin combinations

[lukemm1979]

Hi,

I want to use three incremental encoders with a Teensy 4.1. I understand that only certain pins can be used as clearly stated in the documentation. What I want to confirm is whether there's any restrictions on which pairs of pins from that selection can be used together. Specifically, I want to use [0, 1], [2, 3] and [4, 7] for my three encoders. Am I ok?

Thanks,

Luke

Hi Luke
Sorry fro the long response time. But the short answer to your question is yes you should be ok. If you look at the readme there is one warning and want pins would conflict with each other:
WARNING! Pins 0, 5 and 37 share the same internal crossbar connections and are as such exclusive...pick one or the other. Same thing applies to pins 1 / 36 and 5 / 37.
