I have around six stepper motors that I am controlling with Arduinos. Thes control the actions of an automaton and so need to follow a curve of steps (think an unravelled cam in an old school wooden automaton).
What is the best way to store and retrieve these data curves such that they are easy to test and modify?
My first thought would be using text files to store a list of values so I could plot beziers and export the data. However Arduino does not have an easily accessible storage (I don't want to add an SD card) for text.
My second thought was to plot the cures and fit a polynomial and use that but the iteration time for that could be quite slow ....
Does anyone here have any suggestions?
