Vudoll I would recommend you start there. So I looked at a pretty detailed data sheet and a summary of the data sheet, but have been unsucessfull so far of finding the information I want. How at9sam7x I connect to the board? It turns on both FETs and can create problems.

See the Source Code Organization section for a description of the downloaded files and information on creating a new project. Simply open the rtosdemo. It waits for each packet to be acknowledged individually. You must ensure that the configured MAC address is unique on the network to which the prototyping board is being connected. Open a web browser on the connected computer. Functionality The demo application creates 33 tasks — consisting predominantly of the standard demo application tasks see the demo application section for details of the individual tasks.

Building the demo application for debug Two project configurations are provided. When a buffer is available for processing an EMAC interrupt is generated. The target hardware will serve web pages to a standard web browser. The IP addresses used by the web browser computer and the prototyping board must be at91sam7x The semaphore immediately unblocks the uIP task, which processes the data and if necessary generates a response. Entering the IP address into the web browser obviously use the correct IP address for your system.

Each receive buffer is bytes. Use the tree menu to navigate groups of related pages. Performance is therefore greatly improved by transmitting dynamically generated data as one large packet, rather than multiple small packets. The demo applications included in the FreeRTOS download switch to supervisor mode prior to main being called.

Not all the tasks update an LED so have no visible indication that they are operating correctly. Delivered online or on-site. The driver included in the download uses the EMAC in its most basic configuration. See the Demo Application Hardware Setup notes above. The demo application uses the LEDs built into the prototyping board so no other hardware setup is required. The size of each transmit buffer is equal to the uIP buffer size. This must be set appropriately for your hardware.

Demonstrates the creation of dynamic data with a simple CGI scripting language written by Adam Dunkels. The interaction is further simplified by the single buffer memory management of uIP. 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 with strict real time at1sam7x 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.

The uIP task blocks on the semaphore with a timeout. See the uIP documentation for further information. This is demonstrated by the sample CGI scripts included in the source code download.

Thread aware file system Hint: All the interrupt service routine does is signal to the uIP task via a semaphore that data is available at91zam7x processing. Users must familiarise themselves with the uIP license.

This is the directory to select when prompted for a workspace location during the Eclipse startup process. Be sure to read the Eclipse installation and configuration instructions prior to building the project. It therefore contains many more files than used by this demo.
