how do i know which callback or functions are isr in sdk ? (Trouble with choosing correct API function when using with freertos)

[MCB]

Hello , 

When i am using sdk functions with freertos some of the callbacks/functions requires (for example)  xTaskNotifyFromISR() instead of xTaskNotify. 

So how can i decide if a sdk function or call back function called from ISR or not ? Can we say all the callback functions are ISR in the nrf52 sdk ?

Is there any notation which indicated the function belongs or called from ISR ?

Best regards.

Hello,

You can use the current_int_priority_get() function to check if a function is being run in an interrupt context. But ,most are not because all Softdevice events are processed in a thread. You can see how the SD_EVT_IRQHandler() in nrf_sdh_freertos.c is only used to notify the m_softdevice_task that a new Softdevice event is available.
