Prototype HW counter code on MSP430 Launchpad.
Clean up MSP430 HW counter project comments.
Moved Piccolo trajectory generator project to under uC/C2000
CPU0 timer works, but HW counting pulses using eQEP1 not working yet.
I wrote a lot of code for SPIA on C2000.  Better check it in for now.
L6470 FLAG pin still lit, and not getting valid replies on SPI.  Asked forum.
Got reply on SPI, but L6470 FLAG pin is still deasserted.
Changed SPI clock polarity and phase again, to resolve the FLAG LED
Moved the stepper at half step, 5000 steps/s
Coded the homing states for the stepper.
Stepper handles HOME_SIG.
Stepper homed for the first time.
Redid the stepper state machine to allow for skipped step operation.
Generalize the stepper loops to use N_STEPPER #define
Factor out L6470 IC implementation from the stepper.
Ran into problems while trying to implement 2nd active object.  The stepper itself is back to talking with the IC over SPI and transitions into IDLE state at least.  Better check this in now.
Refactored a bit.
Found that QPN Q_ASSERTs that the initial state to transition somewhere.
First draft of ZRP synchronizing with the stepper(s).  Will implement turning on/off the LED.
Delete TOP/BOTTOM/ABOVE signals and handle them explicitly in TIMEOUT_SIG for each state.  I did this to clarify the checking of the flags, which should be turned off when IDLE.
