tnhnrl 24:c7d9b5bf3829 2 Modified 2017-11-29 revA by Troy
tnhnrl 24:c7d9b5bf3829 3 - changelog.txt carries previous changes
tnhnrl 24:c7d9b5bf3829 4 - Incorporated email changes and did quick bench test
tnhnrl 28:16c83a2fdefa 5 1) In FIND_NEUTRAL, add bce().setPosition_mm(bceFloatPosition) to the one-shot actions after the unpause().
tnhnrl 28:16c83a2fdefa 6 2) NEUTRAL_FIRST_PITCH, changed batt position by half from 1.0 to 0.5.
tnhnrl 28:16c83a2fdefa 7 3) NEUTRAL_SINKING and NEUTRAL_SLOWLY_RISE are using getSetPosition now
tnhnrl 28:16c83a2fdefa 8 4) previousPosition_mm deleted (and print statements changed)
tnhnrl 28:16c83a2fdefa 9 5) NEUTRAL_SLOWLY_RISE check is using bce().getSetPosition_mm()
tnhnrl 28:16c83a2fdefa 10 6) Timers replaced with _neutral_timer variable
tnhnrl 28:16c83a2fdefa 11 7) Default timeout is 8 minutes = 480 seconds
tnhnrl 24:c7d9b5bf3829 12 - Redid the sub-state recording method to only update on state changes
tnhnrl 27:0a5b90cd65d6 13 Modified 2017-11-29 revB by Troy
tnhnrl 27:0a5b90cd65d6 14 - minor print fixes
tnhnrl 28:16c83a2fdefa 15 Modified 2017-11-29 revC by Troy
tnhnrl 28:16c83a2fdefa 16 - removed depthTolerance variable that was not being used.
tnhnrl 28:16c83a2fdefa 17 Modified 2017-11-30 revA by Troy/Dan
tnhnrl 28:16c83a2fdefa 18 - Modified state RISE to setCommand to -1.0 feet (force out of water) and go to next state (float level) when above 0.5 feet
tnhnrl 28:16c83a2fdefa 19 - Modified sub-state NEUTRAL_SINKING to only move 2.5 mm per cycle instead of 5 mm
tnhnrl 28:16c83a2fdefa 20 - Commented out home function (accidentally hit home and got stuck while at LASR)
tnhnrl 28:16c83a2fdefa 21 - Added max depth neutral and dive variables
tnhnrl 28:16c83a2fdefa 22 - Print max recorded depths and current neutral buoyancy positions
tnhnrl 28:16c83a2fdefa 23 Modified 2017-11-30 revB by Troy/Dan
tnhnrl 28:16c83a2fdefa 24 - Dive and Multi-Dive cycles now exit to FLOAT_BROADCAST state
tnhnrl 28:16c83a2fdefa 25 - FLOAT_LEVEL pitchTolerance variable increased from 1.0 degree to 5.0 degrees (PV was difficult to level in LASR pool)
tnhnrl 28:16c83a2fdefa 26 - Added the ability to record the states of the FSM and print to user using keyboard "Z"
tnhnrl 28:16c83a2fdefa 27 Modified 2017-12-01 revA by Troy
tnhnrl 28:16c83a2fdefa 28 - Minor update to 2017-11-30 revB
tnhnrl 28:16c83a2fdefa 29 - Now printing current neutral battery and BCE setpoints and max depth in neutral and dive cycle with "C" (and current sensor data)
tnhnrl 28:16c83a2fdefa 30 - Pool-tested with successful dives.
tnhnrl 28:16c83a2fdefa 31 1) Dive working correctly. (And max dive tracker shows that it is reaching the correct commanded depth.)
tnhnrl 28:16c83a2fdefa 32 2) Float broadcast working correctly. (And we are now going directly from dive and rise to float broadcast.)
tnhnrl 28:16c83a2fdefa 33 3) Neutral sequence has PV diving with -10 to -20 degrees of pitch, battery command seems to be slow or inactive.
tnhnrl 28:16c83a2fdefa 34 3) Float broadcast working correctly.
tnhnrl 28:16c83a2fdefa 35 4) FSM tracker and sub-FSM tracker working.
tnhnrl 28:16c83a2fdefa 36 5) Antenna working until tail just under water (last depth recorded varies between 1.0 and 1.5 feet)
tnhnrl 30:2964617e7676 37 Modified 2017-12-06 revA by Troy
tnhnrl 30:2964617e7676 38 - Added "_isTimeoutRunning = false;" to the FIND_NEUTRAL successful exit case ("else if (runNeutralStateMachine() == NEUTRAL_EXIT)"
tnhnrl 30:2964617e7676 39 1) This will reset the timeout when the PV has successfully found and saved the neutral BCE and battery positions
tnhnrl 30:2964617e7676 40 - Successful dive and multi-dive sequences exit to FLOAT_BROADCAST state (fix was implemented in code that did not respond, reimplemented here)
tnhnrl 30:2964617e7676 41 1) Also made the change to the SequenceController (which loads a file that has multiple sequences)
tnhnrl 31:8616e397c22d 42 - FIND_NEUTRAL starts in NEUTRAL_SINKING with fix on sub-FSM to start with NEUTRAL_SINKING (verified via mbed on bench)
tnhnrl 32:f2f8ae34aadc 43 Modified 2017-12-07 revA by Troy
tnhnrl 32:f2f8ae34aadc 44 - Using new neutral finding sequence, dive slowly, rise slowly, then check pitch (pitch is not active at all until final state)
tnhnrl 32:f2f8ae34aadc 45 - Added additional print information (showing neutral parameters with "C")
tnhnrl 32:f2f8ae34aadc 46 Modified 2017-12-07 revB by Troy
tnhnrl 32:f2f8ae34aadc 47 - Momentum offsets reintroduced:
tnhnrl 32:f2f8ae34aadc 48 1) CASE DIVE uses "else if (depthLoop().getPosition() > depthLoop().getCommand() - 0.5) { // including offset for low momentum approaches"
tnhnrl 32:f2f8ae34aadc 49 2) CASE RISE uses "else if (depthLoop().getPosition() < depthLoop().getCommand() + 0.5) { // including offset for low momentum approaches"
tnhnrl 32:f2f8ae34aadc 50 - Momentum on rise command does not exit properly, removed
tnhnrl 32:f2f8ae34aadc 51 Modified 2017-12-11 revA by Troy
tnhnrl 32:f2f8ae34aadc 52 - Added a logger function the main while loop
tnhnrl 32:f2f8ae34aadc 53 - Added vectors (essentially resizable arrays) to hold the data in the State Machine because of memory limitations
tnhnrl 32:f2f8ae34aadc 54 Modified 2017-12-12 revA by Troy
tnhnrl 32:f2f8ae34aadc 55 - Logger directly implemented in StateMachine (records every 5 seconds)
tnhnrl 32:f2f8ae34aadc 56 Modified 2017-12-12 revB by Troy
tnhnrl 32:f2f8ae34aadc 57 - Logger fixes implemented in StateMachine, was not logging each state, fixed the reset
tnhnrl 32:f2f8ae34aadc 58 - Made logger into a function call
tnhnrl 32:f2f8ae34aadc 59 Modified 2017-12-13 revA by Troy
tnhnrl 32:f2f8ae34aadc 60 - Added function to print log file to screen (tested on bench with multiple dives and timers)
tnhnrl 32:f2f8ae34aadc 61 Modified 2017-12-18 revA by Troy
tnhnrl 32:f2f8ae34aadc 62 - Redo of the code to stop opening and closing files each time
tnhnrl 32:f2f8ae34aadc 63 - This should allow you to write to the open file, then close it once you exit the sequence back to SIT_IDLE
tnhnrl 32:f2f8ae34aadc 64 - Start record in dive, end when you exit float broadcast...
tnhnrl 32:f2f8ae34aadc 65 Modified 2017-12-19 revA by Troy
tnhnrl 32:f2f8ae34aadc 66 - Fixed OpenLog printing to include states and variable names. Currently logs to LOG#####.TXT files
tnhnrl 32:f2f8ae34aadc 67 1) Note: The OpenLog only starts a new log when it is power-cycled (with the MBED)
tnhnrl 34:9b66c5188051 68 Modified 2017-12-20 revA by Troy
tnhnrl 32:f2f8ae34aadc 69 - Modified code to log every 1 second in current iteration
tnhnrl 34:9b66c5188051 70 Modified 2017-12-20 revB by Troy
tnhnrl 34:9b66c5188051 71 - Fixed bug where Dive depth was resetting to rise depth
