Hello everybody,
I have two questions. I'm sorry they're a bit simplistic.
First, what is the accuracy of the timing of a periodic rtthread? Is it up
to +15-20us as when a thread responds to a hardware interrupt?
Second, I am using Xmad4.1 and specifically the rt_max186.o module. The
kernel crashes when the sample rate, which translates I think, to the
frequency of the periodic sampling thread, rises above 5kHz. 5kHz is the
maximum possible frequency listed in the documentation. This, however,
referred to a P-133. 200us seems plenty of time to do the necessary
accesses to the 16550 io port. Surely a Cel-466 would be able to achieve a
higher rate?
thanks for any help people can give,
regards,
Craig
