This page presents an IAR web server and USB demo that is pre-configured to run on the evaluation board that comes in the KSK-LPCPL Kickstart Kit. “Using the FreeRTOS Real Time Kernel – a Practical Guide LPC17xx Edition” is a step by step hands on guide to using FreeRTOS on Cortex M3. We are using LPC microcontroller and LPCXpresso IDE for our have downloaded sample project from FREERTOS website and we are.

The configuration parameters will be set automatically. Open up a dumb terminal such as Hyperterminal and select the enumerated COM port number. Check function – called from the tick hook This only executes every five seconds. Note that a queue is used to pass each individual character between the USB interrupt service routine and the USB task.

This site required JavaScript to be enabled. Setting up the launch configuration.

To create a launch configuration first select ‘Open Debug Dialog Other parameters such as baud rate and flow control settings are not required and can be left at their freeftos values. When executing correctly the demo application will behave as follows: Here are our port files. Served Web Pages The top of each served page includes a menu containing a link to every other page.

When you create a project in Keil, it asks whether to add startup. 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.

Thread aware file system Hint: Unlike most ports, interrupt service routines that cause a context switch have no special requirements and can be written as per the compiler documentation. To use the USB port assuming a Windows host computer: Kickstart versions of Embedded Workbench can only be used with compiled binary images of 32K bytes and under – it is necessary to set the compiler optimisation to ‘medium’ prior to compilation if the Kickstart edition is being used.

Building and executing the demo application Open main. Take care that the ‘Copy projects into workspace’ check box is NOT checked during this last step. As it starts up you will be prompted for a workspace location. Compiler options As with all the ports, it is essential that the correct compiler options are used. Once the linked resource has been set correctly, select ‘Refresh’ from the ‘File’ menu.

Check function – called from the tick hook This only executes every five seconds. These controller specific files are called Port files in which all ports and some functions will be defined mainly in assembly language.

The constants defined in this file can be edited to suit your application. Entering the Frrertos address into the web browser obviously use the correct IP address for your system. The supplied value of Hz is useful for testing the RTOS kernel functionality but is faster than most applications require. The served RTOS stats page showing status information on each task in the system. Note that vPortEndScheduler has not been implemented.

The check box permits the state of the user LED to be set and ,pc1768. Entering the IP address into the web browser obviously use the correct IP address for your system. The served RTOS stats page showing status information on each task in the system.

The target hardware rreertos serve the web pages described below to a standard web browser. Retrieved from ” https: It will ask you to see RVDS directory. The debugger will break on entry to main. If this project fails to build then it is likely the version of IAR Embedded Workbench being used is too old.

This can be ensured by making the first three octets of both IP addresses identical. Thread aware file system Hint: The MAC address and net mask are configured within the same header file. See the Source Code Organization section for a description of the downloaded files and information on creating a new project.

The application should build with no errors or warnings assuming the error statement has been removed. Delete the line it provides instructions on setting up the directory structure for those using the project without first reading these instructions.

The check box permits the state of the user LED to be both set and queried. The Demo Application web server configuration Connect the evaluation board to a computer running a web browser either directly using a point to point plc1768 cable, or via a Ethernet switch using a standard Ethernet cable.
