STM32 can communication filter setting problem

It uses 32 Bit identifier mask bit mode

CAN_FilterIdHigh and CAN_FilterIdLow Combine into one 32 Bit register , Used to store what will be filtered ID

CAN_FilterMaskIdHigh and CAN_FilterMaskIdLow Combine into one 32 Bit register , Used to express this ID Which bits of

Must conform to （ Set up 1）, Which bits are not care（ Set up 0）.

Using the identifier mask mode, you can receive a frame containing a specific location , A series of frames .

 

CAN In the receive mailbox identifier register of ,31~3 Bit storage 29 Bit extension identifier .

 

Therefore, it is necessary to receive through the filter ID by 0x0A Frame of ,

CAN_FilterIdLow = 0x000A << 3; CAN_FilterIdHigh = 0;

CAN_FilterMaskIdLow = 0x00FF << 3; CAN_FilterMaskIdHigh = 0;
