TMS320F28374S: DCAN & FIFO

Part Number: TMS320F28374S

Dear team:

Do we have example routine for DCAN communication with FIFO enabled?

If not, My customer wants to know how to configure DCAN information to avoid the loss of DCAN information due to untimely query if DCAN communication is received by query instead of interruption?

Best regards

    We do not have any example for FIFO as of now.

    Green,

        Let me point to an erratum concerning DCAN FIFO mode ("During DCAN FIFO Mode, Received Messages May be Placed Out of Order in the FIFO Buffer").

    Sorry I don't understand the question. By "query", are you referring to "polling". Are you basically asking how to avoid a message object being over-written? i.e. avoid a Message-lost condition?
