Reading RFID card with STM32f0 series using HAL SPI lib

Hello, I am trying to communicate with rfid rc522 using stm32f0 series processor. Spi driver libary is created using cubemx. I am not able to read card id. I tried arduino to receive data from rfid rc522 it is succesful. But I could not get any data when ı used stm32f0 series kit. There is something wrong with hal spi libray but ı could not get it.

Here is my main.c

Here are my spi rc522 libraries added

Is anyone help me?.
