Hi Juergen, That's normally not something you do and I don't know if it's possible. Application code normally communicates with your driver code using system calls (read/write). So either your appl procedure must be part of your module, or you must signal e.g. a user thread the timer interrupt happened, so the thread can execute that code. Hope this helps,
