Arduino r4 support - added
@PaulStoffregen - @KurtE
When trying to update the library for the new R4 boards (Minima and WiFi) ran into an issue where attaching the interrupt did not work. Thanks to @KurtE found that the issue was with doing it from the constructor which took a while to track down. But he came up with a simple solution that maintains backward compatibility. More can found here: https://forum.arduino.cc/t/encoder-library-attachinterrupt-not-working-from-within-library/1149007
Basically creates a begin method that can be used but when you begin:
Encoder myEnc ;
void setup() { myEnc.begin(2,3); }
This can be used for any board. This method still works though:
Encoder myEnc(2, 3) ;
without using begin in the setup.
I did try it with a Teensy 4.1, Uno, Mega, Nano 33 IoT, and adafruits metro Express m0 board.
@mjs513 I tried your fork today with a R4 WIFI, but sadly, it does not work. I even used a basic example to make sure, it is not an error I introduced in my code. Both variants, with interrupts or not don't give any results.
The encoder itself works fine with the original library and a UNO R3.
Do you have an idea how I could start debugging whats happening?
