/****************************************************************************** | |
* NOTE 1: This project provides three demo applications. A simple blinky | |
* style project, a more comprehensive test and demo application, and an | |
* lwIP example. The mainSELECTED_APPLICATION setting in main.c is used to | |
* select between the three. See the notes on using mainSELECTED_APPLICATION | |
* in main.c. This file implements the simply blinky style version. | |
* | |
* NOTE 2: This file only contains the source code that is specific to the | |
* basic demo. Generic functions, such FreeRTOS hook functions, and functions | |
* required to configure the hardware are defined in main.c. | |
****************************************************************************** | |
* | |
* The lwIP example can be configured to use either a static or dynamic IP | |
* address: | |
* + To use a dynamically allocated IP address set LWIP_DHCP to 1 in | |
* lwipopts.h and connect the target to a network that includes a DHCP | |
* server. The obtained IP address is printed to the UART console. | |
* + To use a static IP address set LWIP_DHCP to 0 in lwipopts.h and set | |
* the static IP address using the configIP_ADDR0 to configIP_ADDR3 | |
* constants at the bottom of FreeRTOSConfig.h. Constants used to define | |
* a netmask are also located at the bottom of FreeRTOSConfig.h. | |
* | |
* When connected correctly the demo uses the lwIP sockets API to create | |
* a FreeRTOS+CLI command console, and the lwIP raw API to create a basic HTTP | |
* web server with server side includes that generate dynamic run time web | |
* pages. See http://www.freertos.org/RTOS-Xilinx-Zynq.html for more | |
* information. | |
* | |
* To connect to FreeRTOS+CLI, open a command prompt and enter "telnet <ipaddr>" | |
* where <ipaddr> is the IP address of the target. Once connected type "help" | |
* to see a list of registered commands. Note this example does not implement | |
* a real telnet server, it just uses the telnet port number to allow easy | |
* connection using telnet tools. | |
* | |
* To connect to the http server simply type the IP address of the target into | |
* the address bar of a web browser. | |
