[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [July 2010 Threads] Why is software interrupt used in FreeRTOSPosted by Angel Eyes on July 4, 2010 I am working with FreeRTOS for ARM7_LPC2106_GCC. I saw in the startup file a call to vPortYieldProcessor in the SWI interrupt handler. Where is SWI used in FreeRTOS?
RE: Why is software interrupt used in FreeRTOSPosted by Dave on July 4, 2010 Did you try searching the source directory for SWI?
RE: Why is software interrupt used in FreeRTOSPosted by Richard on July 4, 2010 SWI is called each time taskYIELD() is called, which can be from inside an API function or just called directly by a task.
