Hi, I would like that a HW interrupt ISR signals a specific task using the function void isr_evt_set (U16 event_flags, OS_TID task_id). I am wondering how to retrieve from the ISR the task_id that was returned by osThreadCreate ? Also, I would like to change at run-time the task that is being signaled, could you please suggest the best method to handle this situation? Thanks for your help, Regards, JC
