Be sure to read the Eclipse installation and configuration instructions prior to building the project. When executing correctly the demo application will behave as follows: See the Source Code Organization section for a description of the downloaded files and information on creating a new project. If you are using a REV C board then: Therefore, to upgrade an older project to the V4.

Open a web browser on the connected computer. The prototyping board may also allow the use of a standard Ethernet cable when connecting point to point, but I have not tried this configuration.
This is the directory to select when prompted for a workspace location during the Eclipse startup process. Delivered online or on-site.

The best way to ensure this is to base your application on the provided demo bosrd files. If this is the first time the kit has been connected then you will be prompted to install 3 USB drivers. The display part number changed on REV C evaluation kit boards.
The interrupt service routine measures the ysb of processor clocks that occur between each interrupt – and in so doing measures the jitter in the interrupt timing.
By continuing to use our site, you consent to our cookies. Compiler options As with all the ports, it is essential that the correct compiler options are used. See the Embedded Ethernet Examples List page for more information. Lowering this value will improve efficiency. Entering the IP address into the web browser obviously use the correct IP address for your system.
The demo projects included in the FreeRTOS download have already been updated so these can be used as an example. The lowest priority on a ARM Cortex-M3 core is in fact – however different ARM Cortex-M3 vendors implement a different number of priority bits and supply library functions that expect priorities to be specified in different ways.

This USB connection is used to power, program and debug the microcontroller. Unlike most ports, interrupt service routines that cause a context switch have no special requirements and can be written as per the compiler documentation.
Therefore, to upgrade an older project to the V4. The OLED task just blocks on the queue waiting for messages – waking and displaying the messages as they arrive. Running the demo application Once again – please refer to the Eclipse installation and configuration instructions for more detailed information. The kit includes two boards: The correct drivers are included on the Luminary Micro CD that came with the kit, alternatively they can be downloaded from the Luminary Micro website.
The ARM Cortex-M3 core has the ability to hasten the entry into an interrupt service routine and therefore reduce latency by up to 8 cycles should a high priority interrupt occur while a lower priority interrupt is already being serviced. The text box can be used to write a message to the OLED display, but does not query the text currently being display.

Be sure to read the Eclipse installation and configuration instructions prior to building the project. The maximum measured jitter time is latched in the ulMaxJitter variable, and displayed on the OLED display by the ‘Check’ task as described below. The supplied value of Hz is useful for testing the RTOS kernel functionality but is faster than most applications require. Evaluwtion the demo application Again – please refer to the Eclipse installation and configuration instructions for more detailed information.
The continuous reloading can sometimes make navigating away from the RTOS stats page a little tricky. The following tasks and tests are created in addition to the standard demo tasks:
