RTOS Timer tick handler is now the same as any other ISR. This causes a few subtle behaviour changes that seem OK but are worth noting: * RTOS tick handler sdk__xt_timer_int() is now called from one stack frame deeper (inside _xt_isr_handler()), whereas before it was called from the level above in UserHandleInterrupt. I can't see any way that the extra ~40 bytes of stack use here hurt, though. * sdk__xt_timer_int() was previous called after all other interrupts flagged in the handler, now it's called before the TIMER FRC1 & FRC2 handlers. The tick handler doesn't appear to do anything particularly timing intensive, though. * GPIO interrupt (value 3) is now lower priority than the SPI interrupt (value 2), whereas before it would have been called before SPI if both interrupts triggered at once. |

Directories: + The FreeRTOS/Source directory contains the FreeRTOS source code, and contains its own readme file. + The FreeRTOS/Demo directory contains a demo application for every official FreeRTOS port, and contains its own readme file. + See http://www.freertos.org/a00017.html for full details of the directory structure and information on locating the files you require. The easiest way to use FreeRTOS is to start with one of the pre-configured demo application projects (found in the FreeRTOS/Demo directory). That way you will have the correct FreeRTOS source files included, and the correct include paths configured. Once a demo application is building and executing you can remove the demo application file, and start to add in your own application source files.
