Simple step counter test

• In data there's some step data from http://forum.espruino.com/conversations/359542
• On main.c we have some step counter code which can be run on

Running

Ensure Espruino is installed at the same level as step-count, as this code expects to use the step counter code from Espruino itself.

Type make && ./main to run and execute the file.

Total difference in steps between expected and calculated is shown.

• expected = what we expect
• orig = step count based on the most trivial step counter

Type make && ./main --bruteforce to run a brute-force check for all possible values using the offline data from data. You can then feed these back into stepcount.c

Graphs

With gnuplot installed you can run gnuplot -p gnuplot.plot to plot graphs of acceleration vs step count/theshold data for debugging.

To compile, run and display the most recent graphs, you can do pkill gnuplot;make clean;make && ./main && gnuplot -p gnuplot.plot
