* \brief Wrapper libraries for <a href="https://savannah.nongnu.org/projects/lwip/lwIP">lwIP</a>
|
||||
*
|
||||
* The following libraries are provided that contain the equivalent lwIP functionality groups:
|
||||
*
|
||||
* * \c \b pico_lwip_core -
|

* * \c \b pico_lwip_core4 -
|

* * \c \b pico_lwip_netif -
|
||||
* * \c \b pico_lwip_sixlowpan -
|
||||
* * \c \b pico_lwip_ppp -
|
||||
* * \c \b pico_lwip_api -
|
||||
*
|
||||
* The following libraries are provided that contain the equivalent lwIP application support:
|
||||
*
|
||||
* * \c \b pico_lwip_snmp -
|
||||
* * \c \b pico_lwip_http -
|
||||
* * \c \b pico_lwip_makefsdata -
|
||||
* * \c \b pico_lwip_iperf -
|

* * \c \b pico_lwip_smtp -

* * \c \b pico_lwip_sntp -
|
||||
* * \c \b pico_lwip_mdns -

* * \c \b pico_lwip_netbios -
|
||||
* * \c \b pico_lwip_tftp -
|
||||
* * \c \b pico_lwip_mbedtls -
|
||||
*
|
||||
* The SDK Provides a common set of functionality in \c \p pico_lwip which aggregates:
|
||||
*
|
||||
* * \c \b pico_lwip_core -
|
||||
* * \c \b pico_lwip_core4 -
|
||||
* * \c \b pico_lwip_core6 -
|
||||
* * \c \b pico_lwip_netif -
|
||||
* * \c \b pico_lwip_sixlowpan -
|
||||
* * \c \b pico_lwip_ppp -
|
||||
*
|
||||
* The following additional libraries are provided:
|
||||
*
|
||||
* * \c \b pico_lwip - Aggregates the lwIP RAW API: \c \b pico_lwip_core, \c \b pico_lwip_core4, \c \b pico_lwip_core6, \c \b pico_lwip_api, \c \b pico_lwip_netif, \c \b pico_lwip_sixlowpan and \c \b pico_lwip_ppp. It does
|
||||
* not include \c \b pico_lwip_api, which requires NO_SYS=0. You should include the latter separately if you want it.
|
||||
*
|
||||
* * \c \b pico_lwip_arch - lwIP required compiler adapters. This is not included in \c \b pico_lwip in case you wish to replace them.
|
||||
* * \c \b pico_lwip_nosys - basic stub functions for NO_SYS mode.
