hello everyone,

can someone help me please, I can't understand why I can't receive 7, it's weird...

I sent 7 , i want to receive 7, but I receive 255, 0, 15.. all the values except 7, that's really insane.

No. That is pins configuration. Show SPI peripheral initialization. Functions like MX_SPIx_Init.
