Got it - the key seems to be on this page: http://www.barello.net/avrx/Theory.htm 3rd paragraph of the "Queue" section states: "Once a process is Sat, 26 Jul 2008 14:55:53 GMT Christopher X.

This is a common mistake It's not explicitly clear in the docs, but Larry explained it in this post from Sat, 26 Jul 2008 14:10:57 GMT Dean Hall http://finance.groups.yahoo.com/group/avrx/message/1809 http://finance.groups.yahoo.com/group/avrx/message/1809 Normally, an interrupt activates the scheduler, so you have pre- emption right there.

Not only possible, but certain AvrX does cooprative multitasking, not premptive. If a task doesn't give up control by a delay or blocking, then it will hog Sat, 26 Jul 2008 12:49:40 GMT Dean Hall http://finance.groups.yahoo.com/group/avrx/message/1807 http://finance.groups.yahoo.com/group/avrx/message/1807 The code examples you give all look good. AvrX is fully pre- emptable.

It also didn't work with bigger stack.

The task re-queued behind the next. Sat, 26 Jul 2008 08:15:40 GMT Neil Johnson http://finance.groups.yahoo.com/group/avrx/message/1804 http://finance.groups.yahoo.com/group/avrx/message/1804 Hi, ... What is the priority of the LED task? What you are trying to do does work - I use the same method in my own systems.

The ISR i use is from the examples. @Dean "Have you created such an ISR and enabled its interrupt?"
