can you use os_create_task() in an interrupt?

Eddie Weigle

Is it possible to use os_create_task() from rtx tiny from within an ISR? Can it corrupt the stack?

    No you cannot use functions that start with os_ within interrupt routines. You must use functions that start with isr_ from interrupts.

    Therefore it is not possible to create a task within an interrupt service routine.

    To guarantee a task is created, use os_create_task() from task 0's initialization code, i.e. before it does any work. The created task can then be then run, but arrange for the created task to block with os_wait1(). Later on, at the end of initialization, turn on the interrupts. An isr_send_signal() within the ISR handler then wakes it up, and you get the effect I think you want.
