hi,

i am trying to run mcp2515 with stm32f303k8 board i am successfully done with Hal but when trying the same function in LL it data register is get some garbage value all time.

I have make sure that transmit part in full duplex working is ok but i am getting garbage in the receive part the in debug i notice that he data register is getting some garbage value,please suggest what could i have done wrong.

The signals you're showing look perfectly valid. Pretend we don't know what values you're expecting. What values are you getting and how do those differ from your expectations?

You also need to ensure the receive buffer is clear prior to sending a byte which you want to read. Otherwise you're going to read stale data.
