RT1064-EVK CAN Bus receive both FrameFormat

Dannii — Fri, 21 May 2021 09:08:45 GMT

Hey Guys,

I want to set up the Can Bus buffer to receive all Messages on a CAN line Standard and Extendet Format. I always just found the settings and masks to change between them, but not a way to receive all of them. I know it has to do something with the IDE Bit, but is there a way to detect it and set the Buffer according to it while recieving the message?

Best regards

Daniel

Hello @Dannii,

If you want to receive multiple messages in a single mailbox the best way would be to use the filters, if you configure the filter mask to 0 it would receive any message in the specific mailbox:

FLEXCAN_SetRxMbGlobalMask(EXAMPLE_CAN, FLEXCAN_RX_MB_STD_MASK(0, 0, 0));
FLEXCAN_SetRxIndividualMask(EXAMPLE_CAN, RX_MESSAGE_BUFFER_NUM, FLEXCAN_RX_MB_STD_MASK(0, 0, 0));

Best Regards,
