xTaskGetSchedulerState API and isrPosted by PENELON on January 30, 2013 Hello, Is it safe to use xTaskGetSchedulerState API from an ISR handler ? No mention of that is done within the documentation. Thanks RE: xTaskGetSchedulerState API and isrPosted by Richard on January 30, 2013 The general rule is "only API functions that end in 'FromISR' can be called from an ISR". As it happens, I have just checked and it is safe to call xTaskGetSceduelrState() from an ISR, but that is co-incidence only. Regards. RE: xTaskGetSchedulerState API and isrPosted by PENELON on January 31, 2013 I did hope so, Maybe an add can be done in documentation and/or API because it was necessary to me to know scheduler state before using xQueueSendToBackFromISR(). Regards RE: xTaskGetSchedulerState API and isrPosted by Artem Pisarenko on April 19, 2013 It causes HardFault in ARM Cortex-M3 MPU port. So it would be nice to have xTaskGetSceduelrStateFromISR() function.
