lwIP network interface integration library

Overview

This library is an integration layer that links the lwIP network stack with the underlying Wi-Fi host driver (WHD) and Ethernet driver. This library interacts with FreeRTOS, lwIP TCP/IP stack, Wi-Fi host driver (WHD), and Ethernet driver. It contains the associated code to bind these components together.

lwIP network interface integration library is an equivalent of Wi-Fi middleware core is now deprecated. Wi-Fi middleware core users can use the porting guide to migrate the application to use lwIP network interface integration library.

Features and functionality

This library is designed to work with both PSoC™ kits with Wi-Fi capability, and XMC™ MCU kits with Ethernet capability, and is supported through the ModusToolbox™ software environment.

Supported platforms

This library and its features are supported on the following platforms:

• PSoC™ 6 Wi-Fi Bluetooth® prototyping kit (CY8CPROTO-062-4343W)

• PSoC™ 62S2 Wi-Fi Bluetooth® pioneer kit (CY8CKIT-062S2-43012)

Log messages

By default, the lwIP network interface integration library disables all debug log messages. Do the following to enable log messages:

1. Add the ENABLE_CONNECTIVITY_MIDDLEWARE_LOGS macro to the DEFINES in the code example's Makefile. The Makefile entry should look like as follows:

   DEFINES+=ENABLE_CONNECTIVITY_MIDDLEWARE_LOGS
   

2. Call the cy_log_init() function provided by the cy-log module. cy-log is part of the connectivity-utilities library. See connectivity-utilities library API documentation for cy-log details.

Dependencies

The lwIP network interface integration library depends on the following:

• lwIP FreeRTOS integration

• lwIP

To ensure that all required libraries are fetched, include ethernet-core-freertos-lwip-mbedtls library depending on the application.

• For Wi-Fi applications:

  Create the wifi-core-freertos-lwip-mbedtls.mtb file with the following content:

  https://github.com/Infineon/wifi-core-freertos-lwip-mbedtls#latest-v1.X#\$$ASSET_REPO$$/wifi-core-freertos-lwip-mbedtls/latest-v1.X

• For Ethernet applications:

  Create the ethernet-core-freertos-lwip-mbedtls.mtb file with the following content:

  https://github.com/Infineon/ethernet-core-freertos-lwip-mbedtls#latest-v1.X#\$$ASSET_REPO$$/ethernet-core-freertos-lwip-mbedtls/latest-v1.X

• Run make getlibs to fetch all required libraries including the lwip-network-interface-integration library.
