Code

In this example an encoder is attached at GPIO26 (A), GPIO14 (B) and GPIO21 (SW)

s = sensor.attach("REL_ROT_ENCODER", pio.GPIO26, pio.GPIO14, pio.GPIO21)
s:callback(
   function(magnitude)
      if (magnitude.dir == -1) then
         print("ccw, value "..magnitude.val)
      elseif (magnitude.dir == 1) then
         print("cw, value "..magnitude.val)
      end
      
      if (magnitude.sw == 1) then
         print("sw on")
      elseif (magnitude.sw == 0) then
         print("sw off")
      end
   end
)
