-This project is designed to drive a bunch of different multiphase motors ( like steppers and brush less motors ) with a high degree of software oversite.  It will use both an Arduino and a Raspberry Pi (or PC, this part will be Python).  The Raspberry PI will download a drive plan to the Arduino which will then execute it.  Generally it will try all the different permutations of the coil connections to see if any of them work.

It is planned to be an update and almost total re-write of the project above.
 We assume a unipolar motor with the common wire identified using resistance measurements.

 * Working, details follow:
 * Have an array download method working in the terminal and Arduino.  Not very slick yet, but basic principal seems ok.
-* Done: Next working on output, first basic then with permutations of the coils set up.
+* Permutation of outputs done.  Will find the working permutation.
 * Tested with stepper motor and it works!
 * Try half step and other drive patterns
-* Try with motors other than steppers esp brush less salvage
+* Try with motors other than steppers esp brushless salvage
 * Hardware is now low side switch Darlingtons, try with other motor drivers.
 * Add some demos and acceleration tests.

-We can do the configuration either by downloads or some version of #defines in the arduino program combined with a recompile.  The generation of the #defines might be generated by the python program.  Right not with only 5 coils seeming pratical or even 6 I think the download can manage the data in a reasonable time.
