Hello RIOT developers,
I have now made some experience with RIOT-OS and I'm working on a port
to the STM32L073.
My problem is sometimes to understand the relationship between the OS parts.
The source code documentation via Doxygen is nice, but not sufficient to
get a real understanding
about the architecture of RIOT and I'm a unhappy to find out how some
parts are working
by "surfing" through the source code. Therefore I will try to enhance
the porting guide and therefore
I will ask you (maybe) some silly questions.....but I think the
questions I will ask are somehow unclear to
a RIOT newbie.
The first question I have is about the xtimer. What is the "official"
purpose of this timer. What should be realised via the xtimer and what
should be realised by the other timers.
The second question - which event triggers the thread context switching?
Scheduled by timers?
Best regards
Bernhard
Best regards,
Bernhard
