Hi, I'm running on a LPC54608 and MCUXpresso, sdk2.7, I have some problems to understand how to receive many frames from standard CAN bus @125kbps. Starting from sdk mcan interrupt example I can receive a single CAN messages but I have some problems receiveing a burst of many messages (e.g. a burst of 10 messages), basically I think I have some problems to understand how RX FIFO works: where can I find basic informations on how CAN fifo works on LPC5460xx? User Manual specs the registers bits but doesn't help me to understand how to use fifo mechanism... I think I need a dummy reference applied on this peripheral? someone can help me?
