| * |
| * \brief Architecture for integrating the CYW43 driver (for the wireless on Pico W) and lwIP (for TCP/IP stack) into the SDK. It is also necessary for accessing the on-board LED on Pico W |
| * |
| * Both the low level \c cyw43_driver and the lwIP stack require periodic servicing, and have limitations |
| * on whether they can be called from multiple cores/threads. |
| * |
| * \c pico_cyw43_arch attempts to abstract these complications into several behavioral groups: |
| * |
| * * \em 'poll' - This not multi-core/IRQ safe, and requires the user to call \ref cyw43_arch_poll periodically from their main loop |
| * * \em 'thread_safe_background' - This is multi-core/thread/task safe, and maintenance of the driver and TCP/IP stack is handled automatically in the background |
| * * \em 'freertos' - This is multi-core/thread/task safe, and uses a separate FreeRTOS task to handle lwIP and and driver work. |
| * |
| * As of right now, lwIP is the only supported TCP/IP stack, however the use of \c pico_cyw43_arch is intended to be independent of |
| * the particular TCP/IP stack used (and possibly Bluetooth stack used) in the future. For this reason, the integration of lwIP |
| * is handled in the base (\c pico_cyw43_arch) library based on the #define \ref CYW43_LWIP used by the \c cyw43_driver. |
| * |
| * \note As of version 1.5.0 of the Raspberry Pi Pico SDK, the \c pico_cyw43_arch library no longer directly implements |
| * the distinct behavioral abstractions. This is now handled by the more general \ref pico_async_context library. The |
| * user facing behavior of pico_cyw43_arch has not changed as a result of this implementation detail, however pico_cyw43_arch |
| * is now just a thin wrapper which creates an appropriate async_context and makes a simple call to add lwIP or cyw43_driver support |
| * as appropriate. You are free to perform this context creation and adding of lwIP, cyw43_driver or indeed any other additional |
| * future protocol/driver support to your async_context, however for now pico_cyw43_arch does still provide a few cyw43_ specific (i.e. Pico W) |
| * APIs for connection management, locking and GPIO interaction. |
| * |
| * \note The connection management APIs at least may be moved |
| * to a more generic library in a future release. The locking methods are now backed by their \ref pico_async_context equivalents, and |
| * those methods may be used interchangeably (see \ref cyw43_arch_lwip_begin, \ref cyw43_arch_lwip_end and \ref cyw43_arch_lwip_check for more details). |
| * |
| * \note For examples of creating of your own async_context and addition of \c cyw43_driver and \c lwIP support, please |
| * refer to the specific source files \c cyw43_arch_poll.c, \c cyw43_arch_threadsafe_background.c and \c cyw43_arch_freertos.c. |
| * |
| * Whilst you can use the \c pico_cyw43_arch library directly and specify \ref CYW43_LWIP (and other defines) yourself, several |
| * other libraries are made available to the build which aggregate the defines and other dependencies for you: |
| * |
| * * \b pico_cyw43_arch_lwip_poll - For using the RAW lwIP API (in `NO_SYS=1` mode) without any background processing or multi-core/thread safety. |
| * |
| * The user must call \ref cyw43_arch_poll periodically from their main loop. |
| * |
| * This wrapper library: |
| * - Sets \c CYW43_LWIP=1 to enable lwIP support in \c pico_cyw43_arch and \c cyw43_driver. |
| * - Sets \c PICO_CYW43_ARCH_POLL=1 to select the polling behavior. |
| * - Adds the \c pico_lwip as a dependency to pull in lwIP. |
| * |
| * * \b pico_cyw43_arch_lwip_threadsafe_background - For using the RAW lwIP API (in `NO_SYS=1` mode) with multi-core/thread safety, and automatic servicing of the \c cyw43_driver and |
| * lwIP in background. |
| * |
| * Calls into the \c cyw43_driver high level API (cyw43.h) may be made from either core or from lwIP callbacks, however calls into lwIP (which |
| * is not thread-safe) other than those made from lwIP callbacks, must be bracketed with \ref cyw43_arch_lwip_begin and \ref cyw43_arch_lwip_end. It is fine to bracket |
| * calls made from within lwIP callbacks too; you just don't have to. |
| * |
| * \note lwIP callbacks happen in a (low priority) IRQ context (similar to an alarm callback), so care should be taken when interacting |
| * with other code. |
| * |
| * This wrapper library: |
| * - Sets \c CYW43_LWIP=1 to enable lwIP support in \c pico_cyw43_arch and \c cyw43_driver |
| * - Sets \c PICO_CYW43_ARCH_THREADSAFE_BACKGROUND=1 to select the thread-safe/non-polling behavior. |
| * - Adds the pico_lwip as a dependency to pull in lwIP. |
| * |
| * |
| * This library \em can also be used under the RP2040 port of FreeRTOS with lwIP in `NO_SYS=1` mode (allowing you to call \c cyw43_driver APIs |
| * from any task, and to call lwIP from lwIP callbacks, or from any task if you bracket the calls with \ref cyw43_arch_lwip_begin and \ref cyw43_arch_lwip_end. Again, you should be |
| * careful about what you do in lwIP callbacks, as you cannot call most FreeRTOS APIs from within an IRQ context. Unless you have good reason, you should probably |
| * use the full FreeRTOS integration (with `NO_SYS=0`) provided by \c pico_cyw43_arch_lwip_sys_freertos. |
| * |
| * * \b pico_cyw43_arch_lwip_sys_freertos - For using the full lwIP API including blocking sockets in OS (`NO_SYS=0`) mode, along with with multi-core/task/thread safety, and automatic servicing of the \c cyw43_driver and |
| * the lwIP stack. |
| * |
| * This wrapper library: |
| * - Sets \c CYW43_LWIP=1 to enable lwIP support in \c pico_cyw43_arch and \c cyw43_driver. |
| * - Sets \c PICO_CYW43_ARCH_FREERTOS=1 to select the NO_SYS=0 lwip/FreeRTOS integration |
| * - Sets \c LWIP_PROVIDE_ERRNO=1 to provide error numbers needed for compilation without an OS |
| * - Adds the \c pico_lwip as a dependency to pull in lwIP. |
| * - Adds the lwIP/FreeRTOS code from lwip-contrib (in the contrib directory of lwIP) |
| * |
| * Calls into the \c cyw43_driver high level API (cyw43.h) may be made from any task or from lwIP callbacks, but not from IRQs. Calls into the lwIP RAW API (which is not thread safe) |
| * must be bracketed with \ref cyw43_arch_lwip_begin and \ref cyw43_arch_lwip_end. It is fine to bracket calls made from within lwIP callbacks too; you just don't have to. |
| * |
| * \note this wrapper library requires you to link FreeRTOS functionality with your application yourself. |
| * |
| * * \b pico_cyw43_arch_none - If you do not need the TCP/IP stack but wish to use the on-board LED. |
| * |
| * This wrapper library: |
| * - Sets \c CYW43_LWIP=0 to disable lwIP support in \c pico_cyw43_arch and \c cyw43_driver |
