I have been searching how to use the FlexCAN interface for the MK10DN512VLQ10, and I need some clarification on how many message buffers are really supported.I've created KSDK1.3+Processor Expert pROJECT
I've configured 3 message boxes as receivers and every message box has its own individual Mask,
There is as structrure in the driver named flexcan_state_t used for pointer to runtime state structure and has a member volatile uint32_t rx_mb_idx;
FLEXCAN_DRV_ConfigRxMb(comCAN1_IDX, 0 , &rx_info1, canRxMsgHandlerList.msgID);
FLEXCAN_DRV_ConfigRxMb(comCAN1_IDX, 1 , &rx_info2, canRxMsgHandlerList.msgID);
FLEXCAN_DRV_ConfigRxMb(comCAN1_IDX, 2 , &rx_info3, canRxMsgHandlerList.msgID);
FLEXCAN_DRV_RxMessageBuffer(comCAN1_IDX, 0, &messageBoxList);
FLEXCAN_DRV_RxMessageBuffer(comCAN1_IDX, 1, &messageBoxList);
FLEXCAN_DRV_RxMessageBuffer(comCAN1_IDX, 2, &messageBoxList);
These are the API s which I have used, as you can see MB1 is configured for ID0 ,MB2 is configured for ID1 and MB2 is configured for ID2 and we get the interrupt only for these mentioned ID's and able to receive data. But corresonding to API ,I need to specify which MB the message will come from.
rx_mb_idx only holds 3rd message box as receive ,when other Message Box (0 and 1 ) receives a message interrupt generated but ISR routine (FLEXCAN_DRV_IRQHandler) wont check 0. and 1. message box.
Kindly let me know what needs to be done with multiple number of message buffer.
