Quick question... I'm writing a 'wrapper' class for Paul's Excellent Encoder™ and Bounce2 classes to provide event driven callbacks, ultimately for a LinuxCNC control panel with four encoders (3 cheapies with push buttons and one CNC style pulse encoder dial).
My question is: How many interrupt pins can I use at once?
I understand on Teensy 4 all digital pins can be used as interrupts but this: https://www.pjrc.com/teensy/interrupts.html in section "Interrupt Vector, Mask & Flag Names" shows only two 'Pin Change' flags.
Does this mean I am limited to just one full hardware interrupt encoder?
