| * 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. | |
