[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [September 2008 Threads] configMAX_PRIORITIES?Posted by Bill Yang on September 5, 2008 Hi, What is different the configMAX_PRIORITIES and configKERNEL_INTERRUPT_PRIORITY? In Cortex_LM3Xxxxx demo, the FreeRTOSConfig.h defines configMAX_PRIORITIES = 5 and configKERNEL_INTERRUPT_PRIORITY = 255. Since the maximum priorities is only 5, why the kernel interrupt priority is 255? Thanks, Bill Yang
RE: configMAX_PRIORITIES?Posted by Dave on September 6, 2008 Again you are confusing task priority with interrupt priority. Task priorities are related to FreeRTOS and interrupt priorities are a characteristic of the hardware. See http://www.freertos.org/a00109.html
