Yes I've tried it, however on an interrupt function it seems to only do half the job! Found something that works, putting a single branch in the ISR to a naked function. At least it seems to work for now, who knows when the compiler will decide to insert a push before my branch and break it all. - Wayne On 11/12/2013, at 16:29, Hynek Sladky <[email protected]> wrote: > Hi Wayne, > > have You tried __attribute__ ((naked)) ?
