FreeRTOS newbie help

Posted by karl80 on November 3, 2014

Hi All, I'm New to SourceForge and Embedded programming. I have only used µC/OSII in school Projects but never tried to link an embedded system for my self so i thought that starting with FreeRTOS would be a good start. I have a LPC2119 ET-Arm stamp card that i would like to get a FreeRTOS working on. Im working with Keil µVision 3 and GCC compiler on a Windows 7 computer.

My question is, have any of you guys any experience working with these Tools and how do I get a FreeRTOS working on LPC2119 with GCC andKeil µVisoin 3??? Any tutorials that i can get help from etc..

See: http://www.freertos.org/Creating-a-new-FreeRTOS-project.html http://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html

for starters.

I think the port layer files in FreeRTOSSourceportableGCCARM7LPC2000 should work for your part, but these are quite old parts and the port layer likewise very old. There is an [equally old] Keil project in FreeRTOSDemoARM7LPC2129KeilRVDS which can probably be targeted for your hardware, but it is using the ARM compiler not GCC. Other than that you will find makefiles for LPC2106 in FreeRTOSDemoARM7LPC2106GCC.

Hi And thanks for the reply. I will look in to this material today and hopefully have a working RTOS soon. I have a questions, since I haven't been working with RTOS since school I would like to know what a " port layer" is. Best regards Karl

The port layer is the small portion of the source code that is specific to one particular architecture - it 'ports' the core kernel code to run on the hardware.
