Using your existing circuit, this program should run
(adapted form code written in 2014)
' simple encoder reading TassyJim Nov 2022
SETPIN gp19, DIN, PULLUP' setup RB as an input
SETPIN gp20, INTH, RInt, PULLUP' setup an interrupt when RA goes high
DO
' < main body of the program >
LOOP
SUB RInt ' Interrupt to decode the encoder output
IF PIN(gp19) = 1 THEN
Value = Value + 1 ' clockwise rotation
ELSE
Value = Value - 1 ' anti clockwise rotation
ENDIF
PRINT Value
END SUB

I tested without any external pullups and small capacitors (0.1uF) on both switch lines as debounce.
