Hello to everybody:
Now, l want to judge whether mailbox 6 is idle or busy,l use library function just as below ago:
if (FLEXCAN_DRV_GetTransferStatus(INST_CANCOM1, TX_MAILBOX_6) != STATUS_BUSY) {
//do something
}
if l want to use register just as "if((CAN0->IFLAG1)&0x00200000)". who can give me some advise,thank you for your helping.
