    Tom suggests implementing a state machine to reproduce the receive
    order. His analysis & solution looks sound to me.<br>

      I spent quite a bit of time on this. With my standard test packet
      of 11 CAN frames expected, and the standard driver, I get perhaps
      4 or 5 of them (about half are lost, and some are out of order).
      <div class=""><br class="">
      </div>
      <div class="">I made the suggested change to move
        the MyCan.IncomingFrame() call out of the ‘can’ object (when
        frameReceived is true) to within the
        mcp2515 AsynchronousInterruptHandler itself. That allows the
        handler to receive more than one frame per call and is a very
        simple change. Once that is done, we can at least now try to
        tune it.</div>
      <div class=""><br class="">
      </div>
      <div class="">So I then modified the code of
        mcp2515 AsynchronousInterruptHandler to loop so long as the
        interrupt flag says either buffer #0 or #1 has a frame. The
        result looks something like this:</div>

        <div>The actual frames on the bus are (B1 values) 54, 45, 40,
          0a, 7a, d5, 0c, 14, 1c, 24, 2c, and 34. Looking at the above
          debug output, we get:</div>
        <div><br class="">
        </div>
        <div>
          <ul class="MailOutline">
            <li class="">Interrupt flags show buffer #0 has a frame. It
              is B1=54. Good.</li>
            <li class="">Interrupt flags show buffers #0 and #1 both
              have frames. Buffer #0 has B1=40 and buffer #1 has B1=45.</li>
            <li class="">Etc etc</li>
          </ul>
        </div>
        <div><br class="">
        </div>
        <div>That is not good. What must have happened is that the first
          B1=54 frame arrived, got put in buffer #0, and interrupt was
          raised. We checked the interrupt flags, found buffer #0 had
          something, and read the frame ok. All is good. But what is
          happening now is that between the time we checked the
          interrupt flags and the time we finished reading the 13 bytes
          from buffer #0, a second frame arrived and was put in buffer
          #1. Then a third frame arrives and is put in buffer #0. We
          loop back to check the interrupt flags and find both buffers
          have frames ready. So we ready buffer #0 to get the third
          frame, then buffer #1 to get the second frame. We are out of
          sequence.</div>
        <div><br class="">
        </div>
        <div>By removing the ESP_LOGD statements, I can improve
          performance enough to get 10 out of the 11 frames, but still
          sometimes frames are swapped in order.</div>
        <div><br class="">
        </div>
        <div>By over-clocking the MCP2515 SPI bus (supposed to be 10MHz,
          but I push it to 15MHz), I can get all 11 frames, but two are
          out of order.</div>
        <div><br class="">
        </div>
        <div>I suppose I can minimise the chance of the out-of-order
          issue by repeating the call to read interrupt flags after
          processing buffer #0 but before checking for buffer #1. That
          would at least reduce the time window to as small as possible,
          but would be another SPI call and is too slow. Doing that
          brings us back to losing frames.</div>
        <div><br class="">
        </div>
        <div>Another approach may relate to our current use of the READ
          command to read 5 status registers (interrupt flags, error
          flags, two skipped, then transmit buffer #0 flags). There are
          two specific commands ‘read status’ (which gets 
the rx and tx
          buffer status flags in one byte), and ‘rx status’ 
(which gets
          just the receive buffer status and some info on the frames
          received, again in one byte). I think those are more designed
          for what we are trying to do. I can try to optimise the read
          loop at the start of the AsynchronousInterruptHandler to use
          one of those - they are 2 SPI bytes vs 7 for what we are doing
          at the moment (so more than three times as fast).</div>
        <div><br class="">
        </div>
        <div>I think it will also be worthwhile having a look at some
          other open source mcp2515 drivers to see how other people are
          doing it.</div>

                                      the handler is meant to read both

                                      I.e. if buffer 1 still has a frame
