例如：
/* CAN0 mailbox0 transmit state */
uint8_t transmit_state = 0;
transmit_state = can_transmit_states (CAN0, CAN_MAILBOX0);

函数名称 can_message_receive
函数原型
void can_message_receive(uint32_t can_periph, uint8_t fifo_number,
can_receive_message_struct* receive_message);
功能描述 CAN接收报文
例如：
/* CAN0 FIFO0 receive message */
can_message_receive(CAN0, CAN_FIFO0, &receive_message);

函数名称 can_receive_message_length_get
函数原型
uint8_t can_receive_message_length_get(uint32_t can_periph, uint8_t
fifo_number);
功能描述获取CAN接收帧的数量
例如：
/* CAN0 FIFO0 receive message length */
uint8_t frame_number = 0;
frame_number = can_receive_message_length_get (CAN0, CAN_FIFO0)
