S2E application with lwIP and FreeRTOS The S2E application implements a serial-to-Ethernet module that provides a means to access the UART port on a TM4C129x device via an Ethernet link. The UART can be connected to the UART on a non-networked device. This can be useful to overcome limitations such as adding multiple serial devices to a shared network and inability to access the device from long distances without modifying the serial device. Telnet protocol is used to transfer the serial data over Ethernet. Two Serial-to-Telnet ports are implemented. The application uses lwIP Stack to manage TCP/IP layers. DHCP or Static IP configuration can be used to obtain an IP address. If DHCP configuration is used, and it times out without obtaining an address, AutoIP will be used to obtain a link-local address. FreeRTOS is used to perform a variety of tasks in a concurrent fashion. The following tasks are created: * An Ethernet task to manage the Ethernet interface and its interrupt. * A TCP/IP task to run the lwIP stack and manage all the TCP/IP packets. This task works very closely with the Ethernet task to server web pages, handle Telnet packets and Locator app packets. Ethernet and TCP/IP tasks are managed by lwIP. * A serial task to manage the serial peripherals and their interrupts. * An idle task (automatically created by FreeRTOS) that manages changes to the IP address and sends this information to the user via Debug UART. To build this application, install TivaWare for C Series v2.1.0.12573 or higher and copy the "enet_s2e" application folder into the EK-TM4C1294XL board's folder at /examples/boards/ek-tm4c1294xl. The IP address and other debug messages are displayed on the Debug UART. UART0, connected to the ICDI virtual COM port, is used as the Debug UART. 115,200 baud with 8-N-1 settings is used to display debug messages from this application. The finder application (in ../../../../tools/bin/) can also be used to discover the IP address of the board. The finder application will search the network for all boards that respond to its requests and display information about them. A configuration webserver is hosted to provide a convenient interface to manage the various configuration options. To access the webserver, enter the IP address of the S2E module in a web browser. The following command can be used to re-build any file system files that change. ../../../../tools/bin/makefsfile -i fs -o enet_fsdata.h -r -h -q For additional details on FreeRTOS, refer to the FreeRTOS web page at: http://www.freertos.org/ For additional details on lwIP, refer to the lwIP web page at: http://savannah.nongnu.org/projects/lwip/ ------------------------------------------------------------------------------- Copyright (c) 2014-2015 Texas Instruments Incorporated.
