ok, i use this for timing. my employer wanted a time sync protocol, a lot of people here tried it but without any success beyond paper. i currently get good results with the cc3200 and i think if i can tweak the sync mechanism i can live with the 53seconds timer overflow.
the timer must be reset in host as well as all nodes, or else the filtering algorithm takes a s**t, i am using a kalman filter to smooth interrupt jitter
what site do you people share graphics on, i have a graph that shows this quite nice
i basically want n nodes that have the same timebase down to < 10us
