annotate Discovery/Src/timer.c @ 407:b11e50415982 Improment_NVM
Bugfix parallel call of external flash functions:
read / write calls to external flash were performed from main loop as well as from timer callback. As result the update of devicedata (every10 minutes) could colidate with the writing of log samples during dive (if logging takes longer then 100ms (clear page). To avoid this raise condition logging of devicedata has been moved to background loop
