Does FreeRTOS support LPC1800

Posted by tungsys on October 24, 2011
Hi all,

May I know whether FreeRTOS support for LPC1800 ?
Or do you have any example running FreeRTOS on LPC1800 ?

The Cortex-M3 port does not use any peripherals outside of the Cortex-M3 core itself. This is because, unlike the ARM7, the interrupt controller and timer source are part of the microcontroller core. Therefore, yes, FreeRTOS does support the LPC1800, because it supports all Cortex-M3 devices.

I don't have an LPC1800 project myself, but know of people using the part. To create a FreeRTOS project for an LPC1800, create a normal C project, install the FreeRTOS interrupt handlers in the vector table (or #define the interrupt handlers to their CMSIS equivalents in FreeRTOSConfig.h and leave the vector table as is, then include the FreeRTOS source files in the project. There are lots of Cortex-M3 examples in the FreeRTOS download, for all the major compilers, that you can use as a reference to see which files are required (or you can buy the LPC17xx edition of the FreeRTOS tutorial book which also tells you which files are needed).
