Flying Sea Glider / Mbed 2 deprecated 2019_10may_firstflight_jcw_nosd

most functionality to splashdwon, find neutral and start mission. short timeouts still in code for testing, will adjust to go directly to sit_idle after splashdown

Dependencies:   mbed MODSERIAL FATFileSystem

tnhnrl 48:20e681885161 2 Modified 2018-02-01 revA by Troy
tnhnrl 48:20e681885161 3 - Fixed bugs with file opening and closing
tnhnrl 48:20e681885161 4 - Made a directory printing function in the MbedLogger class that does not use the Directory List library (removed)
tnhnrl 48:20e681885161 5 Modified 2018-02-02 revA by Troy
tnhnrl 48:20e681885161 6 - Placed mbed file transmitter functionality into MbedLogger class
tnhnrl 48:20e681885161 7 - created a macro for printing out files to PC and serial port simultaneously (placed in main)
tnhnrl 48:20e681885161 8 Modified 2018-02-07 revA by Troy
tnhnrl 48:20e681885161 9 - SDFileSystem class added to code along with sd card file system in System "StaticDefs"
tnhnrl 48:20e681885161 10 - Had to fix bug with SDFileSystem, the imported version uses a buggy FATFileSystem class
tnhnrl 48:20e681885161 11 - Update came from https://os.mbed.com/teams/mbed-official/code/FATFileSystem/ (not the library importer tool)
tnhnrl 48:20e681885161 12 - Modified MbedLogger constructor to include string for file system, e.g. "/sd/" and "/local/"
tnhnrl 48:20e681885161 13 - Modified MbedLogger class to use local or sd card
tnhnrl 48:20e681885161 14 - Created SD card file system using reader on pins p11, p12, p13, p14 (SPI interface)
tnhnrl 48:20e681885161 15 Modified 2018-02-08 revA by Troy
tnhnrl 48:20e681885161 16 - Test code without ADC running to check behavior (timing issue)
tnhnrl 48:20e681885161 17 - Modified sequence to use sequence.txt and fixed warnings
tnhnrl 48:20e681885161 18 - Fixed CRC issue with file reception (the command that the MBED sends out)
tnhnrl 48:20e681885161 19 - Issue with IMU data on p27, need to check wiring and or MAX232
tnhnrl 48:20e681885161 20 Modified 2018-02-14 revA by Troy
tnhnrl 48:20e681885161 21 - IMU tested and working correctly
tnhnrl 48:20e681885161 22 - Data logging on SD card and MBED working simultaneously
tnhnrl 48:20e681885161 23 - State Machine is being used to transmit data over Xbee instead of a separate ticker
tnhnrl 48:20e681885161 24 - Servo driver tested separately in FSG_servo_test program (verified servo works separately)
tnhnrl 49:47ffa4feb6db 25 - Electrical issue with PWM signal interfering with motor driver signal (disabled servo for now)
tnhnrl 49:47ffa4feb6db 26 - Ability to erase MBED (only the MBED) log file through keyboard console
tnhnrl 49:47ffa4feb6db 27 Modified 2018-02-15 revA by Troy
tnhnrl 49:47ffa4feb6db 28 - Made minor changes including cleaning up some functions
tnhnrl 49:47ffa4feb6db 29 Modified 2018-02-15 revB by Troy
tnhnrl 49:47ffa4feb6db 30 - Modified StateMachine class to include manual motor-driving mode and FSM-driven battery and buoyancy engine motor inner loops (CHECK_TUNING)
tnhnrl 49:47ffa4feb6db 31 - Fixed some on-screen printouts in the StateMachine class
tnhnrl 49:47ffa4feb6db 32 - Added CHECK_TUNING state to MbedLogger printouts to MBED and SD card
tnhnrl 49:47ffa4feb6db 33 - Pool tested code worked with several dives. Neutral was BCE: 162 mm, BATT: 36 mm with CHECK_TUNING state; FIND_NEUTRAL (auto-tune) produced 161.0 and 34 mm
