  If you look at the Jonny Mac jm_quadrature_test for P2 its ENC A=40, ENC B=41, and SW=42

  Hmmm... I posted a response to this earlier, but it seems to have disappeared (2021 striking, already?)
  
  I don't like using "magic numbers" for pins, so they're always defined in my apps.
  
  In the version I'm running...

  con { app io pins }
  
    ENC_BTN  = 18  { I }                                          ' active-low encoder connections
    ENC_B    = 17  { I }                                          ' encoder data
    ENC_A    = 16  { I }                                          ' encoder clock
  

  This is the beauty of named constants -- we only have to change them in one place. Note that ENC_BTN is the SW connection on the encoder.
  
  I also like to use specific colors when wiring:
  -- Black for Ground
  -- Orange for 3.3V (Red for 5.0V)
  -- Blue for the SW pin
  -- Yellow for the DT pin
  -- White for the CLK pin
