Excellent. Well done.
As an experiment you could add some code to count loop iterations and check the time. Then you can check that you get as many iterations per minute, hour, day as you expect.
Have some other heavy duty programs running at the same time to see if they affect the results.
No, changing priority with nice will not damage anything. Unless you actually have something else running that also needs the time available.
Also keeping the kernel off of one or more cores won't hurt. Again unless you have other processes that need the time.
Mind you I have no idea what happens when you specify isolcpus=0,1,2,3
I am also using interrupt from wiring pi library to count ticks. Do you think they will interfere with each other? Thanks for your help
