S32K144 CANFD

I want to receive a CANFD message using interrupts.But,I don't know the difference between CAN0_ORed_0_15_MB_IRQHandler and CAN0_ORed_16_31_MB_IRQHandler。

Then， I want to receive CANFD data as a register。Excuse me, how should I operate the register?

Hi,

You have a pointer to received data – it’s type flexcan_msgbuff_t:

typedef struct {

104 uint32_t cs;

105 uint32_t msgId;

106 uint8_t data[64];

107 uint8_t dataLen;

108 } flexcan_msgbuff_t;

There are two interrupt vectors - one for message buffers 0-15 and second for message buffers 16-31.

Regards,

Lukas

After the CAN bus data is interrupted, how do I determine which mailbox is generated? How to configure the filter ID of CAN mailbox?
