Jiacheng:
How are you measuring the latency? I presume you have a scope on a GPIO input
and maybe set a GPIO high when you are inside the ISR and measure the time
between them? Or are you measuring the timing using a task? There is certainly
some hard limitation on interrupt response time but
Thanks.
I'm trying to understand the way it works including docker. There seems
to be some comment on the internet that docker gets in the way, only
supports one process, (so anything spawning a process isn't going to
work ?) - so I started down that route as it seems to be the easiest
way
