hello,
I am new to the usage of eCos and admittedly I am still trying to learn the
ropes with RTOSes and embedded sw.
I got a question related to alarms and counters as they get handled in
eCos. I'd like to have the ability to get the a count of how many ticks are
remaining at any point in time till the expiration of a timer. Since the
internals of Cyg_Alarm class are protected, and there is no api to get to
them I thought someone may have an idea or similar experience. I could do
something like the following :
From the outset I am keeping the period of a timer. By getting the time of
the last expiration I could get to find the number of ticks till the next
expiration.
However, this is not very accurate. Any ideas ?
kind regards,
elias
