This is demonstrated by the sample CGI scripts included in the source code download. Selecting the flash debug configuration. Building the demo application for debug Two project configurations are provided. The demo application uses the LEDs built into the prototyping board so no other hardware setup is required.
This must be set appropriately for your hardware. Performance The uIP stack only permits one packet to be unacknowledged at any one time.
When a buffer is available for processing an EMAC interrupt is generated. Ensure an Ethernet cable is connected as described above. Demonstrates the creation of dynamic data with a simple CGI scripting language written by Adam Dunkels.
Every three seconds the ‘Check’ task examines all the tasks in the at91saam7x256 to ensure they are executing without error.
The prototyping board should also allow the use of a standard Ethernet cable when connecting point to point, but I have not tested this configuration. Fail Safe File System: At1sam7x256 CGI script used to generate the table of tasks transmits the entire table in one packet and therefore loads quickly.

It waits for each packet to be acknowledged individually. Selecting the flash debug configuration Running the demo application The IAR port cannot be executed using the IAR simulator so must be executed on the target hardware. The perl script requires Linux or, as I use, a Cygwin shell.
The size of each transmit buffer is equal to the uIP buffer size. See the uIP documentation for further information. Please refer to the SAM7S demo documentation for more detailed information. Users must familiarise themselves with the uIP license. Thread aware file system Hint: Not all the tasks update an LED so have no visible indication that they are operating correctly. Each receive buffer is bytes. The demo applications included in the FreeRTOS download switch to supervisor mode prior to main being called.
The embedded microcontroller Flash memory will automatically get programmed at91samm7x256 the demo application, and the debugger will break at the reset vector address 0. The interaction is further simplified by the single buffer memory management of uIP.
The uIP task blocks on the semaphore with a timeout. The IP addresses used arrm the web browser computer and the prototyping board must be compatible. The target hardware will serve web pages to a standard web browser. When executing correctly the demo application will behave as follows: Thread aware file system.

The driver included in the download uses the EMAC in its most basic configuration. If you are not using one of these demo application projects then ensure Supervisor mode is entered before calling vTaskStartScheduler.
See the Source Code Organization section for a description of the downloaded files and information on creating a new project. See the Embedded Ethernet Examples List page for more information. This table is interesting for demonstration purposes, but as it is necessary to leave interrupts disabled for an extended period during its creation it is not recommended for use in applications at1sam7x256 strict real time requirements.
