Hello everybody,
have you got any idea what the minimal CPU-frequency is to use the
xtimer_usleep?
Today I tried to configure the xtimer to work with a correct time.
I traced through the code and I think that this jumps throught the
functions cost many
CPU-cycles. I guess that it's not possible to get a 1us time if you have
a slow MCU.
For example if you have 16MHz clock frequency you have only 16cycles to
fire up the
timer. I think all network-drivers use usleeps. Do you agree that this
is a problem?
Best regards,
Bernhard
