* WIP * WIP(1) * done * changelog entry * swint example needs to lose some weight + fix psram * get twai and touch examples back, lcd example to qa, less embassy * more moving * move changelog entry * address reviews upd: revert "is_not_release" check * rebase + a bit more changes remove useless feature * address review remove inappropriate doctest tutorial * get all sleep examples back and to qa-test fmt * get rid of some redundant printlns in doctests * etm timer upd * make printlns great again * writeln! -> println! * clear "timer with interrupts" doctest
