Take care that the ‘Copy projects into workspace’ check box is NOT checked during this last step. Delete the line it provides instructions on rfeertos up the directory structure for those using the project without first reading these instructions. The best way to ensure this is to base your application on the provided demo application files.

The USB task simply echoes received characters with an offset which by default is one. If ‘x’ is received ‘y’ will be echoed back, etc. Apart from all these files you freerots also need lpc header files. It cannot be executed successfully from within the Eclipse environment itself. The LCD task just blocks on the queue waiting for messages – waking and displaying the messages as they arrive.

The MAC address and net mask are configured within the same header file. Its main function is to check that all the standard demo tasks are still operational. The application should build with no errors or warnings assuming the error statement has been removed. See the Embedded Ethernet Examples List page for more information. To use the USB port assuming a Windows host computer: Click ‘New’ to create a new linked resource.

freegtos Open up a dumb terminal such as Hyperterminal and select the enumerated COM port number. The target hardware will serve the web pages described below to a standard web browser. Open a web browser on the connected computer. The IP addresses used by the web browser computer and the evaluation board must be compatible. See the Source Code Organization section for rreertos description of the downloaded files and information on creating a new project.

The MAC address and net mask are configured within the same header file. Interrupt service routines In the demo application the vector table remains in flash. Here we will be using Keil compiler.

Other parameters such as baud rate and flow control settings are not required and can llc1768 left at their default values.

Note that a queue is used to pass each individual character between the USB interrupt service routine and the USB task. Connect the MCB to the host computer using your choice of debug interface – then connect to the target by selecting “Connect” from the “Target” menu.

This is a convenient method for a slow echo server, but very inefficient if large amounts of data are to be transferred.

Use the supplied examples as a reference. The tasks consist primarily of the standard demo tasks see the demo application section for details of the individual tasks. Select “Download and Debug” from the “Project” menu – the demo application should build with lpc178 errors or warnings before being programmed into the LPC Flash memory.

The IP addresses used by the web browser computer and the MCB development board must be compatible. When executing correctly the demo application will behave as follows: Entering the IP address into the web browser obviously use the correct IP address for your system.
