Convert the few remaining cr/lf files to use lf for eol. (#1316)
If you develop on windows and need cr/lf files, see this: https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#_formatting_and_whitespace Git can handle this by auto-converting CRLF line endings into LF when you add a file to the index, and vice versa when it checks out code onto your filesystem. You can turn on this functionality with the core.autocrlf setting. If you're on a Windows machine, set it to true - this converts LF endings into CRLF when you check out code: $ git config --global core.autocrlf true

One thing I noticed is different between my initial idea of stack

assignments to RTC threads, when comparing to interrupts, is that I

interrupts of different priorities share an interrupt stack.

It's not really a difference in memory usage, because when assigning

multiple priorities to a stack, you have to add-up worst-case for

all priorities. One possible functional difference is that with

separate stacks per priority, it's possible to dynamically change

the priority of an RTC thread (while it's running). Not sure how
|

valuable that might be -- changing priority is useful with priority
|
||||
inheritance, to avoid priority inversion, but I don't know how often
|
||||
an RTC thread might acquire a lock (it couldn't block on acquiring a
|

lock in the usual sense -- it could get queued waiting and be restarted
|

when it becomes available, or use try_lock instead of lock).
