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 served run time stats page showing the processor utilisation of each task.

Unlike most ports, interrupt service routines that cause a context switch have no special requirements and can treertos written as per the compiler documentation. These tasks consist predominantly of the standard demo application tasks see the demo application section lpc17768 details of the individual tasks.

Delivered online or on-site. See the Source Code Organization section for a description of the downloaded files and information on creating a new project. When executing correctly the demo application will behave as follows: Changes are sent to the target hardware by clicking the “Update IO” button. The text box can be used to write a message to the LCD, but does not query the text currently being display.

The IP addresses used by the web browser computer and the LPC development board must be compatible. Entering the IP address into the web browser obviously use the correct IP address for your system. Delivered online or on-site.

Select the option to manually select the. If ‘x’ is received ‘y’ will be echoed back, etc.

The check box permits the state of the user LED to be both set and queried. Importing the FreeRTOS project into the Red Suite workspace Web server configuration Connect the RDB development board to a computer running a web browser either directly using a point to point crossover cable, or via a Ethernet switch using a standard Ethernet cable.

The following tasks and tests are created in addition to the standard demo tasks: Connect the LPC to your host computer using the USB device port of the evaluation board ensuring the jumpers are set correctly for device operation, see the underside of the board for jumper settings.

Each will toggle at a different but fixed frequency.

The MAC address and net mask are configured within the same header file. To create a launch configuration first select ‘Open Debug Dialog 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.

Interrupt priorities must be set in accordance with the instructions on the Customisation page for correct operation. The check box permits the state of the user LED to be set and queried. The best way to ensure this is to base your application on the provided demo application files.


Use the tree menu to navigate groups of related pages.


Type ‘A’ into the terminal window, if everything is working correctly you should see ‘B’ echoed back. Fail Safe File System: Once the linked resource has been set correctly, select ‘Refresh’ from the ‘File’ menu. Use the supplied examples as a reference.

Entering the IP address into the web browser obviously use the correct IP address for your system Served Web Pages The top of each served page includes a menu containing a link to every other page. The supplied value of Hz is useful for testing the RTOS kernel functionality but is faster than most applications require.


Entering the IP address into the web browser obviously use the correct IP address for your system. Its main function is to check that all the standard demo tasks are still operational. If its lpc7168 first time of freertps any RTOS, it will be really confusing for you. The microcontroller used was a pre-production prototype that has numerious differences to the production parts now available and is therefore not yet configured for optimum performance.
