Zero reading

Hello
I'm trying to read the encoder, but I always get 0 as encoder feedback. Already checked the connection of the wires and is correct.
I use pins 19,21,23 SPI.
I am also using a level shifter..
What did you do with the ls7366r "SS /" pin?
Any suggestion?
Apologies for late reply.
Did you manage to solve your issue?
Take a look at the datasheet, page 12. Do you have the LS7366R wired the same way?
As for your question about the SS pin this is what it does:
SS/ (Pin 4) A high to low transition at the SS/ (Slave Select) inputselects the LS7366R for serial bi-directional data transfer; alow to high transition disables serial data transfer and bringsthe MISO output to high impedance state. This allows for theaccommodation of multiple slave units on the serial I/O.
Best,
OK, problem solved I had to change pins on the raspberry.
Thank you Mateus! :)
