By the way : i have 100n caps, not the 10n. |

Oh wait those are pullup-resistors, and i have those internal in the PIC, hmz. So you need pullups disabled in the MCU for this one. --- End quote --- Yeas they are, as only uneducated designer connects 100nF large capas accross the contacts directly. It will wear the shit out of the contacts in no time. Either filter completely in SW, or use a reasonable HW approach. (100nF across a finicky tiny mechanical contact is not one of them.) |

What do you mean ?, without resistor the encoder will wear out faster ? I dont see how. |
