Exit sleep mode (``MCR.SLEEP = 0``). +5. Enable automatic bus-off management (``MCR.ABOM``) and TX FIFO priority + mode (``MCR.TXFP``). +6. Program bit timing into ``CAN->BTR``. +7. Install an accept-all hardware filter (bank 0, 32-bit mask mode, + mask = 0 / id = 0). +8. ``start()`` leaves init mode, drains any stale FIFO0 entries, clears the + overrun flag (``FOVR0``), and enables the ``FMPIE0`` (FIFO-message-pending) + interrupt. + +TX path -- 3 hardware mailboxes +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The bxCAN peripheral has **3 TX mailboxes** (``sTxMailBox[0..2]``). +``transmit()`` scans mailboxes 0-1-2 for the first one whose ``TME`` bit is set +in ``CAN->TSR``, writes the frame ID (standard or extended), DLC, and 8 data +bytes, then sets ``TXRQ`` to trigger hardware arbitration and transmission. + +On successful queueing, ``TMEIE`` (TX-mailbox-empty interrupt enable) is set so +that ``transmitISR()`` fires when a mailbox completes. ``transmitISR()`` clears +the ``RQCP`` flag for all three mailboxes; if every mailbox is now idle, it +masks ``TMEIE`` to suppress spurious interrupts. + +If all three mailboxes are occupied, ``transmit()`` returns ``false`` and the +caller must retry. + +RX path -- 2 hardware FIFOs, software queue +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The bxCAN has **2 receive FIFOs** (FIFO0 and FIFO1), each **3 messages deep**. +This driver uses FIFO0 exclusively. + +``receiveISR()`` is called from ``CAN1_RX0_IRQHandler``. It loops while +``RF0R.FMP0 != 0``, reading each frame from ``sFIFOMailBox[0]`` (the hardware +always presents the oldest pending frame at index 0). Each frame is: + +1. Checked against an optional software bit-field filter (byte array indexed by + ``CAN-ID / 8``; the bit at position ``CAN-ID % 8`` set means "accept"). + Rejected frames are released from the FIFO without storing. +2. Stored in a **32-entry circular software queue** (``fRxQueue[]``). New + frames are written at index ``(fRxHead + fRxCount) % RX_QUEUE_SIZE``. If + the queue is full the hardware FIFO entry is released silently (no frame + loss notification). +3. Released from the hardware FIFO (``RFOM0``). + +The thread-side retrieves frames via ``getRxFrame(index)`` and advances the +head with ``clearRxQueue()``. + +Filter banks -- 28 banks, 2 modes +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The bxCAN provides **28 filter banks** shared between CAN1 and CAN2. Two +configuration modes are exposed: + +- ``configureAcceptAllFilter()`` -- bank 0 in 32-bit mask mode with id = 0 + and mask = 0 (accept everything into FIFO0). +- ``configureFilterList(idList, count)`` -- banks 0..13 in **32-bit identifier- + list mode**, packing 2 standard 11-bit IDs per bank.

Enable the FDCAN peripheral clock on APB1 (``RCC->APB1ENR1 |= FDCANEN``). +2. Select the FDCAN kernel clock source as PCLK1 (``CCIPR[25:24] = 10``). + The reset default is HSE, which may not be enabled on all boards. +3. Configure TX and RX GPIO pins (alternate function, speed, pull-up). +4. Enter init mode (``CCCR.INIT``; poll until set), enable configuration change + (``CCCR.CCE``). +5. Disable CAN FD operation (``CCCR.FDOE = 0``, ``CCCR.BRSE = 0``). +6. Program nominal bit timing into ``FDCAN->NBTP``. +7. Configure message RAM layout via ``RXGFC`` (filter list sizes) and ``TXBC`` + (TX FIFO mode, ``TFQM = 0``). +8. Install an accept-all global filter (``RXGFC.ANFS = 0``, ``RXGFC.ANFE = 0`` + routes non-matching standard and extended frames to RX FIFO 0). +9. ``start()`` configures interrupts (see below) and clears ``CCCR.INIT`` to + join the bus. + +Message RAM layout (STM32G4) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Each FDCAN instance owns a fixed **212-word (848-byte)** region in SRAMCAN. +Instance base addresses: + +======== ======================== +Instance Offset from SRAMCAN_BASE +======== ======================== +FDCAN1 ``0x000`` +FDCAN2 ``0x350`` +FDCAN3 ``0x6A0`` +======== ======================== + +Within each instance the layout is: + +============================= ============ ====== ==================== +Region Elements Words Offset range +============================= ============ ====== ==================== +Standard ID filter elements 28 x 1 word 28 ``0x000`` -- ``0x06F`` +Extended ID filter elements 8 x 2 words 16 ``0x070`` -- ``0x0AF`` +RX FIFO 0 3 x 4 words 12 ``0x0B0`` -- ``0x0DF`` +RX FIFO 1 3 x 4 words 12 ``0x0E0`` -- ``0x10F`` +TX Event FIFO 3 x 2 words 6 ``0x110`` -- ``0x127`` +TX Buffers 3 x 4 words 12 ``0x128`` -- ``0x157`` +============================= ============ ====== ==================== + +This layout is **fixed in hardware** on STM32G4 -- there are no configuration +registers to relocate sections (unlike the M_CAN IP on STM32H7 which has +``SIDFC``, ``XIDFC``, ``RXF0C``, etc.). + +TX path -- message RAM TX FIFO +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +``transmit()`` checks the TX FIFO free level (``TXFQS.TFFL``). If non-zero, +it reads the put index (``TXFQS.TFQPI``), computes the TX buffer element +address in message RAM (``ramBase + 0x128 + putIdx * 16``), writes the 4-word +TX element (ID word, DLC word, two data words), and sets the corresponding bit +in ``TXBAR`` to request transmission. + +Each TX buffer element is 16 bytes (4 words): + +- **Word 0** -- CAN ID. Standard IDs are shifted to bits [29:18]; extended IDs + occupy bits [28:0] with the XTD bit (bit 30) set. +- **Word 1** -- DLC in bits [19:16]. FDF and BRS are zero (classic CAN). +- **Words 2--3** -- 8 data bytes in little-endian order. + +RX path -- snapshot drain pattern +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +``receiveISR()`` is called from the FDCAN RX ISR (interrupt line 0). It +implements a **snapshot drain**: the fill level (``RXF0S.F0FL``) is read +**once** at ISR entry, and only that many elements are drained. + +**Why snapshot drain?** The FDCAN hardware continues to receive frames into the +FIFO even after ``RF0NE`` (RX FIFO 0 New Element) is disabled in the ``IE`` +register. If the ISR looped on ``F0FL != 0`` on a busy bus, it would never +exit because new frames arrive between iterations. The snapshot guarantees +bounded ISR execution time. + +For each element: + +1. Read the get index (``RXF0S.F0GI``) and compute the element address + (``ramBase + 0x0B0 + getIdx * 16``). +2. Parse the 4-word RX element into CAN ID, DLC, and payload. +3. Apply the optional software bit-field filter. +4. Store in the 32-entry circular software queue, or silently drop if full. +5. Acknowledge by writing the get index to ``RXF0A``. + +After draining, the ISR clears ``RF0N``, ``RF0F``, and ``RF0L`` flags in +``FDCAN->IR`` (write-1-to-clear semantics). + +Software RX queue +~~~~~~~~~~~~~~~~~ + +Both ``BxCanDevice`` and ``FdCanDevice`` use an identical circular queue: + +- ``RX_QUEUE_SIZE = 32`` frames. +- ``fRxHead`` -- index of the oldest unread frame. +- ``fRxCount`` -- number of frames currently buffered. +- New frames written at ``(fRxHead + fRxCount) % 32``. +- ``getRxFrame(i)`` returns the frame at logical index ``i`` (relative to head). +- ``clearRxQueue()`` advances the head and resets the count. + +The transceiver layer must call ``disableRxInterrupt()`` before reading the +queue and ``enableRxInterrupt()`` after ``clearRxQueue()`` to prevent the ISR +from modifying the queue concurrently. This avoids disabling global interrupts. + +Interrupt routing -- ILS grouped bits (STM32G4) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The STM32G4 FDCAN groups interrupt sources into coarse categories in the +``FDCAN->ILS`` register (unlike the per-source routing available on M_CAN in +STM32H7). ``start()`` configures: + +- ``FDCAN_ILS_SMSG`` (bit 2) = 1 -- routes the "Successful Message" group + (which includes TX Complete, ``TCE``) to **interrupt line 1**. +- RX FIFO 0 group (bit 0) = 0 -- stays on **interrupt line 0** (default). +- Both lines enabled via ``ILE = EINT0 | EINT1``. + +This allows separate NVIC vectors for RX and TX without contention. + +Filter elements in message RAM +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- ``configureAcceptAllFilter()`` -- sets ``RXGFC.ANFS = 0`` and + ``RXGFC.ANFE = 0`` so that all non-matching standard and extended frames + are accepted into RX FIFO 0. No filter elements are programmed. +- ``configureFilterList(idList, count)`` -- programs up to 28 standard-ID + filter elements in message RAM. Each element is a single 32-bit word: + + - ``SFT = 01`` (dual ID filter for exact match). + - ``SFEC = 001`` (store matching frames in RX FIFO 0). + - ``SFID1 = target ID``, ``SFID2 = target ID`` (exact match). + + Non-matching frames are rejected (``RXGFC.ANFS = 2``, ``RXGFC.ANFE = 2``). + The filter list size is written to ``RXGFC.LSS``. + +Error counters +~~~~~~~~~~~~~~ + +- ``isBusOff()`` -- reads ``FDCAN->PSR.BO``. +- ``getTxErrorCounter()`` -- ``FDCAN->ECR.TEC`` (0--255). +- ``getRxErrorCounter()`` -- ``FDCAN->ECR.REC`` (0--127, 7-bit field). + + +Design Decisions +---------------- + +Why snapshot drain instead of loop-until-empty? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +On a busy 500 kbps bus with 10+ nodes, a new frame can arrive in the hardware +FIFO every 230 us (minimum-length standard frame). If the ISR polled +``F0FL != 0`` (FDCAN) or ``FMP0 != 0`` (bxCAN) as its loop condition, a +sustained burst could keep the ISR running indefinitely, starving all +lower-priority interrupts and the main loop. + +The FDCAN driver reads ``F0FL`` once and drains exactly that many elements. +The bxCAN driver loops on ``FMP0`` directly (the 3-deep hardware FIFO +naturally bounds the iteration to at most 3 frames per ISR invocation), so +a snapshot is unnecessary for bxCAN. + +Why a software RX queue? +~~~~~~~~~~~~~~~~~~~~~~~~~ + +The bxCAN hardware FIFO is only 3 frames deep; the FDCAN RX FIFO 0 is also 3 +elements on STM32G4. At 500 kbps with multiple transmitters, 3 frames can +arrive in under 1 ms. A 32-frame software queue gives the application up to +~7 ms of buffering headroom (worst case: all minimum-length frames) before +frame loss occurs. This decouples ISR latency from application scheduling +jitter. + +Why separate BxCanDevice and FdCanDevice classes? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The bxCAN and FDCAN peripherals have fundamentally different register layouts: + +- bxCAN uses memory-mapped mailbox structures (``sTxMailBox[]``, + ``sFIFOMailBox[]``) and a separate filter bank register file. +- FDCAN uses a shared message RAM with configurable (STM32H7) or fixed + (STM32G4) element offsets, and filter elements are written directly to RAM. + +Attempting to unify them behind a common base class would require virtual +dispatch in ISR context (unacceptable for hard-real-time CAN) or extensive +``#ifdef`` blocks that would reduce readability.

This avoids disabling + * global interrupts while still preventing receiveISR() from modifying the + * queue concurrently. + * + * 4. **Filter banks** — Two modes are provided: accept-all (mask mode, bank 0) + * and identifier-list (list mode, banks 0..13, 2 IDs per bank).

New frames are stored at + * index `(fRxHead + fRxCount) % RX_QUEUE_SIZE`; the thread retrieves them + * starting at fRxHead via getRxFrame() and advances the head with + * clearRxQueue(). When the software queue is full, hardware FIFO elements + * are still acknowledged (to prevent FIFO overrun) but the payload is + * silently dropped. + * + * ### ISR re-entry prevention (snapshot drain) + * receiveISR() reads the FIFO fill level (F0FL) once at entry and drains + * only that many elements. This prevents an infinite loop on a busy bus + * where new frames arrive faster than the ISR can consume them. After + * draining, RF0N / RF0F / RF0L interrupt flags are cleared atomically + * (write-1-to-clear on FDCAN->IR). + * + * ### ILS grouped bits (STM32G4-specific) + * Unlike M_CAN on STM32H7 which offers per-source interrupt routing, + * the STM32G4 FDCAN groups interrupt sources into coarse categories. + * Setting FDCAN_ILS_SMSG routes the "Successful Message" group + * (which includes TX Complete) to interrupt line 1, while the RX FIFO 0 + * group defaults to interrupt line 0.

It implements global interrupt disable/enable primitives and +integrates with FreeRTOS for context-safe critical sections. + +Global Interrupt Disable / Enable +---------------------------------- + +The header ``interrupts/disableEnableAllInterrupts.h`` provides two inline +assembly functions: + +``disableAllInterrupts()`` + Executes ``CPSID I`` to set the ``PRIMASK`` register, masking all + interrupts except NMI and HardFault. Followed by ``ISB``, ``DSB``, and + ``DMB`` barrier instructions to ensure the mask takes effect before any + subsequent memory access or instruction fetch. + +``enableAllInterrupts()`` + Executes ``ISB``, ``DSB``, and ``DMB`` barriers first, then ``CPSIE I`` to + clear ``PRIMASK`` and re-enable interrupts. The barrier-before-enable + ordering ensures all pending memory operations complete before interrupts + can fire. + +Both functions are declared ``static inline`` with +``__attribute__((always_inline))`` to guarantee zero-overhead inlining at every +call site. + +PRIMASK vs BASEPRI +------------------ + +The Cortex-M4 offers two mechanisms for interrupt masking: + +**PRIMASK (bare-metal variant)** + Setting PRIMASK to 1 disables all configurable interrupts (priority levels + 0--15). Only NMI (priority -2) and HardFault (priority -1) remain active. + This is the approach used by ``disableAllInterrupts()`` / + ``enableAllInterrupts()`` and is suitable for bare-metal critical sections + where no RTOS is running. + +**BASEPRI (FreeRTOS variant)** + FreeRTOS uses ``BASEPRI`` instead of ``PRIMASK`` for its critical sections. + Setting ``BASEPRI`` to ``configMAX_SYSCALL_INTERRUPT_PRIORITY`` masks only + interrupts at or below that priority threshold, leaving higher-priority + (lower numeric value) interrupts unmasked. This allows time-critical ISRs + (e.g., motor control, safety watchdog) to preempt FreeRTOS critical + sections. + + FreeRTOS-aware critical section macros (``taskENTER_CRITICAL`` / + ``taskEXIT_CRITICAL``) use this BASEPRI approach internally. The + ``bspInterruptsImpl`` module provides the ``SuspendResumeAllInterruptsScopedLock`` + RAII wrapper for C++ code that needs interrupt-safe sections compatible with + both variants. + +NVIC Priority Configuration +---------------------------- + +The STM32 Cortex-M4 implements 4-bit priority grouping (``FEATURE_NVIC_PRIO_BITS = 4`` +in ``mcu/mcu.h``), yielding 16 priority levels (0 = highest, 15 = lowest). + +Priority assignment guidelines: + +- Priorities 0--3: Reserved for time-critical hardware ISRs that must not be + blocked by FreeRTOS critical sections (above + ``configMAX_SYSCALL_INTERRUPT_PRIORITY``). +- Priorities 4--15: Available for ISRs that may call FreeRTOS API functions + (``xSemaphoreGiveFromISR``, ``xQueueSendFromISR``, etc.). + +The ``ENABLE_INTERRUPTS()`` and ``DISABLE_INTERRUPTS()`` macros in ``mcu/mcu.h`` +map directly to ``__enable_irq()`` / ``__disable_irq()`` CMSIS intrinsics for +use by the FreeRTOS Cortex-M4 port layer. + +Scoped Lock +----------- + +The ``SuspendResumeAllInterruptsScopedLock`` class (from the ``interrupts`` +namespace) provides RAII-style interrupt locking: + +.. code-block:: cpp + + { + const ESR_UNUSED interrupts::SuspendResumeAllInterruptsScopedLock lock;

It selects the correct vendor CMSIS device header based on the +build-time preprocessor symbol: + +- ``STM32F413xx`` -- includes ``stm32f413xx.h`` (STM32F413ZH, Cortex-M4F, + 1536 KB Flash, 320 KB SRAM) +- ``STM32G474xx`` -- includes ``stm32g474xx.h`` (STM32G474RE, Cortex-M4F, + 512 KB Flash, 128 KB SRAM) + +If neither symbol is defined the build fails with a ``#error``. + +Additional definitions in ``mcu.h``: + +``INCLUDE_CORE_CM4_IN_MCU_H`` + Guard required by the OpenBSW-patched ``core_cm4.h``. + +``ENABLE_INTERRUPTS()`` / ``DISABLE_INTERRUPTS()`` + Macros mapping to ``__enable_irq()`` / ``__disable_irq()`` intrinsics. Used + by the FreeRTOS Cortex-M4 SysTick port. + +``FEATURE_NVIC_PRIO_BITS`` + Set to ``4`` (16 priority levels). Matches the STM32 4-bit priority + grouping, consistent with the S32K1xx platform port. + +Vendor device headers (``stm32f413xx.h``, ``stm32g474xx.h``) and CMSIS +``core_cm4.h`` reside under the ``3rdparty/`` directory and are provided by ST +Microelectronics. + +Startup Assembly +---------------- + +Each target has a dedicated startup file in ``startup/``: + +- ``startup_stm32f413xx.s`` -- 102 interrupt vectors per RM0430 Table 40 +- ``startup_stm32g474xx.s`` -- 102 interrupt vectors per RM0440 Table 97 + +Both files share the same structure: + +``Reset_Handler`` + 1. Load stack pointer from ``_estack`` (top of SRAM, defined by linker + script). + 2. Copy ``.data`` section from Flash (``_sidata``) to SRAM + (``_sdata`` .. ``_edata``). + 3. Zero-fill ``.bss`` section (``_sbss`` .. ``_ebss``). + 4. Call ``SystemInit`` (weak, defaults to no-op infinite loop if not + overridden -- typically overridden by ``configurePll()`` via + ``bspClock``). + 5. Call ``__libc_init_array`` (C++ static constructors and + ``preinit_array`` / ``init_array``). + 6. Call ``main()``. + +``Default_Handler`` + Infinite loop. All interrupt handlers are declared as weak aliases to + ``Default_Handler`` so that unhandled interrupts trap deterministically. + +``g_pfnVectors`` + The vector table placed in the ``.isr_vector`` section. Contains the + initial stack pointer, 15 Cortex-M4 system exception entries, and all + device-specific external interrupt entries. + +Linker Scripts +-------------- + +Board-specific linker scripts are maintained alongside each board's +``referenceApp`` platform entry point, not in ``bspMcu``: + +- ``executables/referenceApp/platforms/nucleo_g474re/main/linkerscript/application.ld`` +- ``executables/referenceApp/platforms/nucleo_f413zh/main/linkerscript/application.ld`` + +They are wired to the final ELF via the ``PROP_LINKER_SCRIPT`` property on the +``startUp`` INTERFACE library. See each board's ``main/CMakeLists.txt`` for +details. + +Software Reset (``softwareSystemReset``) +---------------------------------------- + +``reset/softwareSystemReset.h`` declares a single ``extern "C"`` function: + +.. code-block:: c + + void softwareSystemReset(void); + +This wraps the CMSIS ``NVIC_SystemReset()`` call, which writes the +``SYSRESETREQ`` bit in the Cortex-M4 Application Interrupt and Reset Control +Register (``SCB->AIRCR``). The function does not return. + +Dependencies +------------ + +- CMSIS ``core_cm4.h`` (ARM) +- ST vendor device headers under ``3rdparty/`` +- ``mcu/typedefs.h`` for platform type aliases diff --git a/platforms/stm32/bsp/bspMcu/include/3rdparty/cmsis/LICENSE b/platforms/stm32/bsp/bspMcu/include/3rdparty/cmsis/LICENSE new file mode 100644 index 00000000000..8dada3edaf5 --- /dev/null +++ b/platforms/stm32/bsp/bspMcu/include/3rdparty/cmsis/LICENSE @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

+Overview +-------- + +The ``bspTimer`` module implements the system timer for STM32 Cortex-M4 targets. +It uses the ARM Data Watchpoint and Trace (DWT) cycle counter -- a core debug +unit register available on all Cortex-M4 devices -- rather than a chip-specific +peripheral timer. This makes the implementation portable across STM32 families. + +DWT Cycle Counter +----------------- + +The DWT ``CYCCNT`` register is a free-running 32-bit counter that increments at +the core clock frequency (HCLK). The module reads three memory-mapped registers +directly: + +``DWT_CTRL`` (``0xE0001000``) + Control register. Bit 0 (``CYCCNTENA``) enables the cycle counter. + +``DWT_CYCCNT`` (``0xE0001004``) + Current cycle count value (32-bit, wraps at 2^32). + +``DEMCR`` (``0xE000EDFC``) + Debug Exception and Monitor Control Register. Bit 24 (``TRCENA``) must be + set to enable DWT and ITM access. + +Initialisation (``initSystemTimer``) +------------------------------------ + +Called once during BSP bring-up with interrupts locked: + +1. Set ``TRCENA`` in ``DEMCR`` to enable the trace unit. +2. Reset ``DWT_CYCCNT`` to zero. +3. Set ``CYCCNTENA`` in ``DWT_CTRL`` to start counting. +4. Clear the internal tick accumulator and last-DWT snapshot. + +Tick Accumulation +----------------- + +The internal ``updateTicks()`` function extends the 32-bit ``CYCCNT`` to a +64-bit monotonic tick counter. Each tick represents 1 microsecond: + +.. code-block:: text + + elapsed_cycles = CYCCNT_now - CYCCNT_last + elapsed_us = elapsed_cycles / DWT_FREQ_MHZ + +Where ``DWT_FREQ_MHZ`` is: + +- **96** for STM32F4 (96 MHz HCLK) +- **170** for STM32G4 (170 MHz HCLK) + +The family is selected at compile time via ``STM32_FAMILY_F4`` or +``STM32_FAMILY_G4``. ``updateTicks()`` runs under +``SuspendResumeAllInterruptsScopedLock`` to prevent CYCCNT from advancing +between the read and the delta calculation. + +Public API +---------- + +All functions are declared ``extern "C"`` for use from both C and C++ code: + +``uint64_t getSystemTicks(void)`` + Returns the 64-bit monotonic tick count (1 tick = 1 us). + +``uint32_t getSystemTicks32Bit(void)`` + Lower 32 bits of the tick count.

Uses + ``getSystemTimeUs()`` polling -- not interrupt-driven. + +FreeRTOS Integration +-------------------- + +The DWT timer is independent of the SysTick peripheral.

Returns + ``CAN_ERR_ILLEGAL_STATE`` if not in ``CLOSED`` state. +- ``open()`` -- calls ``BxCanDevice::start()`` (leaves init mode, drains stale + FIFO entries, enables ``FMPIE0``). Transitions ``INITIALIZED`` or ``CLOSED`` + to ``OPEN``. If called from ``CLOSED``, re-initializes the hardware first. + Clears the ``fMuted`` flag. +- ``open(frame)`` -- delegates to ``open()``. The wake-up frame parameter is + ignored (bxCAN does not support wake-up frames). +- ``close()`` -- calls ``BxCanDevice::stop()`` (masks ``FMPIE0`` and + ``TMEIE``, enters init mode). Transitions any state to ``CLOSED``. Returns + ``CAN_ERR_OK`` if already closed. +- ``shutdown()`` -- delegates to ``close()``. +- ``mute()`` -- suppresses transmission while keeping the peripheral active + (RX still operational).

Transitions ``MUTED`` to + ``OPEN``. + + +TX Path +------- + +``write(frame)`` checks that the transceiver is in ``OPEN`` state and not +muted, then delegates to ``BxCanDevice::transmit()``. If the hardware returns +``false`` (all 3 TX mailboxes full), ``CAN_ERR_TX_HW_QUEUE_FULL`` is returned. +On success, registered sent-listeners are notified synchronously via +``notifySentListeners()``. + +The overload ``write(frame, listener)`` additionally calls +``listener.canFrameSent(frame)`` on success. + +Baud rate: **500000 bps** (returned by ``getBaudrate()``). + +Hardware queue timeout: **10 ms** (returned by ``getHwQueueTimeout()``). + + +ISR Dispatch +------------ + +The transceiver uses **static dispatch functions** indexed by ``busId`` +(0..2), stored in a 3-element ``fpTransceivers[]`` array. This allows the +Cortex-M NVIC vector table to call a plain C-linkage function that resolves to +the correct transceiver instance. + +``receiveInterrupt(transceiverIndex)`` +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Called from ``CAN1_RX0_IRQHandler`` (or equivalent for CAN2/CAN3).

Returns the number of frames stored in the software queue. + +After the ISR completes, the RX interrupt (``FMPIE0``) remains enabled -- the +bxCAN hardware FIFO is only 3 deep, so the ISR naturally terminates after +draining at most 3 frames. + +``transmitInterrupt(transceiverIndex)`` +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Called from ``CAN1_TX_IRQHandler``. Delegates to +``BxCanDevice::transmitISR()`` which clears ``RQCP`` flags and conditionally +masks ``TMEIE`` when all mailboxes are idle. + +FMPIE0 disable/re-enable pattern +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +To prevent a race between the ISR writing to the software queue and the thread +reading from it: + +1. ``disableRxInterrupt(index)`` -- masks ``FMPIE0`` in ``CAN->IER``. +2. The thread reads frames via ``getRxFrame()`` and clears the queue. +3. ``receiveTask()`` calls ``clearRxQueue()`` followed by + ``enableRxInterrupt()`` -- unmasks ``FMPIE0``. + +This avoids disabling global interrupts while still providing mutual exclusion +on the software RX queue. + + +RX Path -- receiveTask() +------------------------ + +``receiveTask()`` runs in the ``async`` task context (not ISR context). It: + +1. Reads the current frame count from ``BxCanDevice::getRxCount()``. +2. Iterates over all buffered frames, calling ``notifyListeners()`` for each + (dispatches to all registered ``ICANFrameListener`` instances). +3. Calls ``clearRxQueue()`` to advance the head pointer. +4. Calls ``enableRxInterrupt()`` to re-enable ``FMPIE0``. + + +Bus-Off Recovery +---------------- + +``cyclicTask()`` is invoked periodically from the ``async`` timeout context. +It polls ``BxCanDevice::isBusOff()`` (reads ``CAN->ESR.BOFF``): + +- If bus-off is detected while in ``OPEN`` state, the transceiver transitions + to ``MUTED``. The ``fMuted`` flag is **not** set, indicating this was an + automatic transition (not user-initiated). +- If bus-off clears (the bxCAN peripheral has ``ABOM`` -- automatic bus-off + management -- enabled, so hardware automatically attempts recovery after 128 + occurrences of 11 consecutive recessive bits) and the user did not explicitly + call ``mute()``, the transceiver transitions back to ``OPEN``. +- If the user explicitly called ``mute()`` (``fMuted == true``), the + transceiver stays ``MUTED`` even after bus-off clears.
