File content as of revision 92:52a91656458a:

    Modified FSG PCB V_1_1
        - Freezes when doing a dive or any timed sequence (commented out SD card references)
        - commented out sdLogger().appendLogFile(current_state, 0);     //open SD file once
        - commented out sdLogger().appendLogFile(current_state, 1);    //writing data
        - commented out sdLogger().appendLogFile(current_state, 0);    //close log file
        - reduced timer to 20 seconds for bench testing
        - modified ConfigFileIO for rudder()
        - added in getFloatUserInput function from newer code
        - changed LinearActuator & batt() in StaticDefs to match new pinouts from Bob/Matt/Troy fixes
        - slowed down battery motor because it's silly fast at 30 volts (bench test)
            * BCE gain is proportional 0.1 now 0.01
        - BATT was moving in the wrong direction, gain was P: 0.10, I: 0.0, D: 0.0
            * change gain to P: -0.10 (gain was flipped, I think the old circuit board had the voltages flipped ? ?)
        - StateMachine changes for testing
            * added keyboard_menu_STREAM_STATUS();
            * added keyboard_menu_RUDDER_SERVO_settings();
        - modified the zero on the battery position from 610 to 836
        - BMM (batt) slope may be incorrect, seems low, currently 0.12176
        - modified the zero on BCE from 253 to 460
        - Pressure readings are wrong
            * added readADCCounts() to omegaPX209 class to see channel readings
            * modified omegaPX209 class to use filtered ADC readings from SpiADC.readCh4()
        - fixed rudderLoop to headingLoop from newer code
    Modified FSG PCB V_1_2
        - added init headingLoop to main
        - added pitch and heading outputs to STREAM_STATUS
    NOTE: Flipped motor controller output on connector side with battery mass mover (BMM)
        - Motor direction was opposite the BCE motor (because of gearing) 
        - BMM P gain is now positive 0.02 (from -0.10)
    Modified FSG PCB V_1_3
        - added timing code for interrupt that drives the rudder (testing with o-scope)
        - PID controller replaced with newer version from 5/29 code branch
        - StateMachine hanged style of variables to match convention in code
    Modified FSG PCB V_1_4
        - adc tests
    Modified FSG PCB V_1_5
        - IMU update
        - Testing print outs
    Modified FSG PCB V_1_6
        - new BMM zero count of 240 (confirmed manually)
        - new BCE zero count of 400 (confirmed manually)
        - Modified emergency climb to go to position 10 on the BMM, not zero (almost relying on the limit switch)
        - fixed keyboard input; including typing in the timeout (can enter exact times)
    Modified FSG PCB V_1_7
        - removed data logger references
        - fixed bug where I was logging data twice in the interrupt code and the main file
        - fixed bug where Multi-Dive sequence wasn't restarting (the counter used to get the current state was not reset)
    Modified FSG PCB v_1_7C
        - fixing a bug with the data transmission (output had newline character) because of packet lengths
        - new version blasts data and Python program requests lost packets, dramatically faster over USB, slightly faster over XBee
        - fixed some format and terminal errors
    Modified code 2018-08-06
        - fixed bug with heading save feature, wasn't updating deadband properly
        - modified input on servo sub-menu
    Modified code 2018-08-07
        - Float broadcast changed to command rudder to center in that state (whatever center is in the file)    
        - Was sending the wrong command to the position dive (BMM)
    Modified code 2018-08-14
        - Fixed the deadband on "case Float_Broadcast" so it exits properly, I was seeing the BCE stop around 317 so I made a fixed deadband of 4.0 (anything 316 or above will exit the state)
        - FIND_NEUTRAL was code was double-checked:
            1) Starts with an offset of 25 mm from the manually found neutral BCE position (still buoyant), BMM starts at that neutral position
            2) case NEUTRAL_SINKING: Every 5 seconds it retracts the BCE 5 mm.  When it reaches the input depth setpoint it switches to NEUTRAL_RISING
            3) case NEUTRAL_SLOWLY_RISE:  Every 5 seconds it extends the BCE 2 mm.  When it starts to rise (depth rate is negative) (depth rate positive is sinking, negative is rising) it will immediately stop
             and go to case NEUTRAL_CHECK_PITCH.  Removed an incorrect line of code that was setting BCE position with depthloop output.
            4) case NEUTRAL_CHECK_PITCH: Every 10 seconds the pitch is adjusted +/- 0.5 mm depending on whether the nose is pitched up or pitched down
                 (the timing is because the PV may move around in the water before it stabilizes)
        - Homing Sequence now moves at -0.5 not -0.1 (was way too slow)
    Modified code at Carderock (2018-08-15)
        - Removed -1 multiplier from IMU outputs
        - Pitch is incorrectly oriented now, pitch down
        - Heading/Yaw is off by 90 degrees I believe (north is not north)
        - Did not check roll
        - KNOWN ISSUE of log file not having consistent line length (will throw off python data receiver)
    Modified code at Carderock (2018-08-16)
        - Observations at LASR lead to fixes on the save PID files, zero offsets were saving incorrectly, fixed
    2019 feb 15 Modified code jcw
        - LogOO?.csv name and version number is set with logvers.txt
        - DIAG00?.txt likewise set with logvers.txt
        - diagnostic logging to diagnostics file
        - legfile.txt sets parameters ( max-depth, min_depth, heading, timeout, yo_time)  for a dive leg, after which mbed program ends
             to allow monitor computer to access via usb filesystem
        - added states:  Leg_position_dive, leg_position_rise,  fb_exit to handle above yo-yo leg and exit
             have not yet added these states in menu operations.
        STILL TO DO:
        -  test size of log file and set new log file name and update logvers.txt
        -  allow for something other than 0=leg  in legfile.txt so that state will NOT drop into legfile.txt operations mode
        -  add access to leg_position_dive ( with exit??)  to menu operations  -maybe
25 feb 2019    DONE:   jcw
       -  added state ENDLEG_WAIT - will drop to keyboard/FLOAT_BROADCAST if char is read over xbee() while waiting
       - test time for log file to be cycled - in main.cpp
       -  convert from feet to meters in depth().getposition()  calls ( deep inside outerloop() )
07may2019    DONE as of now   jcw
       -  fixed version of posvelfilt that can deal with heading variables
       -  state FLYING_IDLE  that is to be ended  by a pulldown on a DigitalIn line - presently has a timeout for  testing
       -  state START_SWIM  that is started automatically at end of FLYING_IDLE and splashdown wait
       -  Find_Neutral will run immediately if splashdown ends with FSG upside down, but START_SWIM will exit the mbed program
          and return control to Raspberry PI for communications.
           I have not yet exercised code that would run if the FSG submerges and does  not self -right under water.
           It should happen soon. I think I do that on the bench.
       -  FIND_NEUTRAL  will be run if flag and file showing neutral found has not been set - this is important in my view.
          if find Neutral fails, file is written to warn raspberry PI
       -  lots of flashing leds()  to indicate still running.
       -  runs on bare board.  still to be tested with FSG  full system, or even pieces - such as imu().
