In the question: Very accurate time measurement, Rocketmagnet show a circuit that is exactly what I need for a cub scout pinewood derby race track timer. I want to be able to dedicate a timer to each event and get accurate times for each event to +/- 100 ns.
I have not designed, built or programmed any real time control circuits / computer systems in 15 years and need a set of suggestions on where to start, what tools I need and preferably a suggestion for an eval board that I can use to start with. I can learn the newer RT programming compilers, debuggers and tools and implement any sensor circuits but need a starting point to pick the correct MCU.
Any help in getting started is appreciated.
