Greetings forum! In short about the project: I am using lika I41 encoder with an 8-wired cable (AB0 signal) which reads the revolutions of an engine. 3 of the encoder`s wires are soldered up to the RPi in the following way: 4 pin - 5v, 6 pin - GND, 34 and 36 pin - 0-signal wire. The signal wire is soldered to input (36 pin) and GND (34 pin) because on 34th I am using a diode to decrease a Voltage from 5V to 3.3V. I am using 0-signal because it sends only 1 signal per revolution which is perfect not to overload my program (don`t see a need to describe the purpose of it and code specs). The only thing to mention about the code is that I am using Python RPi gpio library to read the signal from the encoder. But as mentioned in the title, RPi just doesn`t see the signal, despite the encoder does send it properly (I have checked with an oscilloscope, signal is 3.3V as needed).
Attaching some debugging code that I used to check the signal (it always output 1).

Clik here to view.
Will be thankful for any advice! Thanks in advance.
