There is an attempt to scan for transmit buffers that are available, if none are available, it checks 2 more times before returning to user (0) that a transmit wasnt possible. IFCT m圜AN = IFCT(1000000,FLEXCAN0_BASE) // initialize with 1Mbps on Can0 (register base address) ħ) The. IFCT m圜AN = IFCT() // initialized default, 1Mbps on Can0 everything else goes in global callback, including the individual which goes to both.Ħ) The constructor is pretty basic with only 2 initializers:
This allows you to handle specific mailboxes with interrupts. Void onReceive(_MB_ptr handler) /* global callback function */ Void onReceive(const IFCTMBNUM &mb_num, _MB_ptr handler) /* individual mailbox callback function */ (m圜AN.pollFIFO(msg, 1))(disable interrupt)(CAN.pollFIFO(msg, 0))(enable interrupt)ĥ) Callbacks, you have a global callback, and, if necessary, I've added individual mailbox callbacks as well! The interrupts are restored when pollFIFO is called with a 0 overload.
This allows users to access frames directly rather than handling in their callbacks. Secondly, I havn't added masking/filter support yet as I work on the structure, but by default I enable both in FIFO mode and mailbox mode all frames accepted, again, until it matures, then they will be addedġ) FIFO (enabled or disabled dynamically), with interrupt capability (enableFIFOInterrupt/disableFIFOInterrupt)Ģ) Dynamic mailbox setup support: setMB(MB9, TX) (transmit mailbox), or setMB(MB9,RX,IDE) (setup an extended ID reception box)ģ) Individual mailbox interrupt enabling (*.enableMBInterrupt(MB5)/*.disableMBInterrupt(MB5) Ĥ) there is a pollFIFO() function that can give a user direct access to the FIFO frames, and at the same time, disable MB/FIFO interrupts, for as long as you poll frames. Hi, I decided to work on a different twist of the current libraries and forks of collin80, teachop, and pawelsky, and rework most of the existing code from scratch into a new library that has, currently, these features:īefore you ask, I'm currently doing it on a 3.6 and only for FLEXCAN0 until it matures, only then I would add CAN1 support and 3.2 registersĭebug will be enabled for initial version for any testers interested on testing, and suggesting other ideas to implement.
