My rotary encoder adventures

[Demon]

Henrik, inspired by your code. I got down to 6.4 - 8.6us:

Goes in initialization section:

    Enc1_previous = %11111111
    Enc1_Current = %00000000
    Enc1_counter = 0

MainLoop:

MyLogic:

    Enc1_Current = (Enc1_WiperA << 1) + Enc1_WiperB

    IF Enc1_Current != Enc1_Previous THEN
        IF Enc1_Current = %00000011 THEN
            IF Enc1_Previous = %00000010 THEN
                Enc1_counter = Enc1_counter + 1
            ELSE
                IF Enc1_Previous = %00000001 THEN
                    Enc1_counter = Enc1_counter - 1
                ENDIF
            ENDIF
        ELSE
            IF Enc1_Current = %00000000 THEN
                IF Enc1_Previous = %00000001 THEN
                    Enc1_counter = Enc1_counter + 1
                ELSE
                    IF Enc1_Previous = %00000010 THEN
                        Enc1_counter = Enc1_counter - 1
                    ENDIF
                ENDIF
            ENDIF
        ENDIF
    ENDIF
    
    Enc1_Previous = Enc1_Current

    BlinkLED1 = 0                       ' Bottom of IFs on Logic 2 probe

    GOSUB LCDoutput
    
    goto mainloop

Since my encoder doesn't stop on 01 or 10, I only need to check 11 and 00. Already 3 times faster than my original.
