danstrider | 10:085ab7328054 | 2 | Starting from Trent's Linear Actuator code from 2017-10-19, these modifications |
danstrider | 10:085ab7328054 | 3 | by Dan add an outer loop controller for depth and pitch to command the inner |
danstrider | 10:085ab7328054 | 4 | linear actuator loops. |
danstrider | 10:085ab7328054 | 5 | Modified 2017-10-20 revA by Dan |
danstrider | 10:085ab7328054 | 6 | - added outer loop controller, but it is hanging the mbed. (turns out it was the imu update) |
danstrider | 10:085ab7328054 | 7 | Modified 2017-10-22 revA by Dan |
danstrider | 10:085ab7328054 | 8 | - outer loop now works with a call to outerloop.update() in main loop(), not with an attached ticker |
danstrider | 10:085ab7328054 | 9 | Modified 2017-10-22 revB by Dan |
danstrider | 10:085ab7328054 | 10 | - enabled both depth and pitch outer loop controllers |
danstrider | 10:085ab7328054 | 11 | - added ability to keyboard reset |
danstrider | 10:085ab7328054 | 12 | Modified 2017-10-22 revC by Dan |
danstrider | 10:085ab7328054 | 13 | - major update to the IMU library processing to make a state machine that doesn't hang |
danstrider | 10:085ab7328054 | 14 | - added lat/lon/alt and GNSS fix information to the IMU library |
danstrider | 10:085ab7328054 | 15 | - brought out the pin names into the constructors of IMU, omega, SpiADC |
danstrider | 10:085ab7328054 | 16 | Modified 2017-10-22 revD by Dan |
danstrider | 10:085ab7328054 | 17 | - everything seems to be working, shy of re-checking on the hardware |
danstrider | 10:085ab7328054 | 18 | - Depth sensor call done inside the OuterLoop, but should somehow be set as a callback instead |
danstrider | 10:085ab7328054 | 19 | - IMU sensor call done inside the OuterLoop, but should somehow be set as a callback instead |
danstrider | 10:085ab7328054 | 20 | Modified 2017-10-23 revA by Dan/Matt |
danstrider | 10:085ab7328054 | 21 | - linear actuator hardware works great, limit switches, sensing, etc. |
danstrider | 10:085ab7328054 | 22 | - outer loops run, but move the BCE in the wrong direction. |
danstrider | 10:085ab7328054 | 23 | - new IMU code doesn't read from the sensor correctly, but doesn't hang up either. |
danstrider | 10:085ab7328054 | 24 | - depth sensor worked fine, just needs zero bias adjustment. |
danstrider | 11:3b241ecb75ed | 25 | Modified 2017-10-24 by Troy |
danstrider | 11:3b241ecb75ed | 26 | - added offset to outerloop |
danstrider | 11:3b241ecb75ed | 27 | Modified 2017-10-26 by Dan |
danstrider | 11:3b241ecb75ed | 28 | - brought over a state machine and new keyboard controls ... currently just dumped into main. |
danstrider | 11:3b241ecb75ed | 29 | Modified 2017-10-26 by Matt |
danstrider | 11:3b241ecb75ed | 30 | - new IMU code imported and working well with the hardware. |
danstrider | 11:3b241ecb75ed | 31 | Modified 2017-10-26 revB by Dan |
danstrider | 11:3b241ecb75ed | 32 | - This version has been in the pool. |
danstrider | 11:3b241ecb75ed | 33 | - Get occasional ADC bad string pot batt & piston. On initial sensor reads, see negative positions. |
danstrider | 11:3b241ecb75ed | 34 | But after running FLOAT_BROADCAST, string pot positions are normal. Not sure why. |
danstrider | 11:3b241ecb75ed | 35 | - Repeatedly got stuck in RISE with a +60s timeout. Battery hit end bell and stalled out. |
danstrider | 11:3b241ecb75ed | 36 | - keyboard and state machine are in main, probably shouldn't be, but easier to debug. |
danstrider | 11:3b241ecb75ed | 37 | - Really happy with the logic and flow of the state machine. Timeouts work. |
danstrider | 11:3b241ecb75ed | 38 | - Need to add a means to drive the linear actuators manually ... toggle out stop() in SIT_IDLE. |
danstrider | 11:3b241ecb75ed | 39 | - Need to add keyboard commands to modify the zeroOffset positions. |
danstrider | 14:85b64a4d08e8 | 40 | Modified 2017-10-30 by Dan, Trent, Matt, Troy |
danstrider | 14:85b64a4d08e8 | 41 | - changed .stop() to .pause() and many .start() to .unpause() ... fixed the negative ADC and lets |
danstrider | 14:85b64a4d08e8 | 42 | the PVF's keep running even though the motor isn't moving. |
danstrider | 14:85b64a4d08e8 | 43 | - changed exit conditions to use filtered depth from the outer loop. less noisy. |
danstrider | 14:85b64a4d08e8 | 44 | Modified 2017-10-31 by Dan, Matt |
danstrider | 14:85b64a4d08e8 | 45 | - added oversampling and a tare function to the depth sensor. |
danstrider | 14:85b64a4d08e8 | 46 | - updated main and keyboard to include tare in setup() and a keyboard tare option. |
danstrider | 14:85b64a4d08e8 | 47 | - looks like the piston isn't zeroing correctly, unclear why, should be unrelated to depth sensor. |
danstrider | 15:2a8cfd3f1cf5 | 48 | Modified 2017-10-31 (again) by Dan, Matt, and Troy |
danstrider | 15:2a8cfd3f1cf5 | 49 | - POOL TESTED! |
danstrider | 15:2a8cfd3f1cf5 | 50 | - Tuned the PID gains with magic. Works to hold mostly level during BCE runs. Dive is awesome. |
danstrider | 15:2a8cfd3f1cf5 | 51 | - Neutral won't do what we want ... without large depth P, it won't get to depth. |
danstrider | 15:2a8cfd3f1cf5 | 52 | - Dive with just P doesn't overshoot depth at 0.0 deg, but does with -20 deg. Timeout should probably be RISE. |
danstrider | 15:2a8cfd3f1cf5 | 53 | - Files depth/pitch updated with tuned defaults. |
tnhnrl | 16:3363b9f14913 | 54 | Modified 2017-11-06 by Troy |
tnhnrl | 16:3363b9f14913 | 55 | - Added acronyms to print statements (when running this with XBee you don't know what mode the |
tnhnrl | 16:3363b9f14913 | 56 | hardware is in because of signal dropping out) |
tnhnrl | 16:3363b9f14913 | 57 | - Fixed print error with setpoints by printing out the setpoint variable, not the outerloop getCommand |
tnhnrl | 16:3363b9f14913 | 58 | (command is sent every time hardware dives, finds neutral, etc.) |
tnhnrl | 16:3363b9f14913 | 59 | - Set the pitchCommand input to 0 on the "find neutral" command, it was sending a non-zero pitch command |
tnhnrl | 16:3363b9f14913 | 60 | - Created a class for the StateMachine |
tnhnrl | 17:7c16b5671d0e | 61 | Modified 2017-11-14 by Troy |
tnhnrl | 17:7c16b5671d0e | 62 | - Changed tare to void function (functions does not return anything when called) |
tnhnrl | 17:7c16b5671d0e | 63 | - Added a "subclass" in the cases for the Neutral Finding Sequence (Sinking, Slowly Rise, Check Pitch (and save positions)) |
tnhnrl | 17:7c16b5671d0e | 64 | Modified 2017-11-20 by Troy |
tnhnrl | 17:7c16b5671d0e | 65 | - Modified StateMachine class to separate keyboard inputs from FSM |
tnhnrl | 17:7c16b5671d0e | 66 | - Added Neutral Finding sub-statemachine |
tnhnrl | 17:7c16b5671d0e | 67 | - Verified both state machines are working with hardware on desktop |
tnhnrl | 17:7c16b5671d0e | 68 | - Added class to save neutral battery and buoyancy engine positions to neutral.cfg file |
tnhnrl | 17:7c16b5671d0e | 69 | Modified 2017-11-21 by Troy |
tnhnrl | 17:7c16b5671d0e | 70 | - Need to check remove ConfigFileIO and place saving functions into config_functions.cpp (rename ConfigFunctions.cpp) |
tnhnrl | 17:7c16b5671d0e | 71 | - Added multi-dive (and multi-rise) states to FSM (may incorporate single dive states into states) |
tnhnrl | 17:7c16b5671d0e | 72 | - Need to double-check behavior of sub-FSM but bench-top testing showed correct behavior for transition from sinking, to slowly rise, to check pitch |
tnhnrl | 17:7c16b5671d0e | 73 | - Need to add a check for the multi-dive sequence file (sequence.cfg) being loaded on the MBED |
tnhnrl | 20:8987a9ae2bc7 | 74 | Modified 2017-11-21 by Dan |
tnhnrl | 20:8987a9ae2bc7 | 75 | - removed blocker and set up a loop rate timer that runs the state machine and keyboard at 10 Hz. |
tnhnrl | 20:8987a9ae2bc7 | 76 | - work inside StateMachine and particularly in the findNeutralSubState. |
tnhnrl | 21:38c8544db6f4 | 77 | Modified 2017-11-22 by Troy |
tnhnrl | 21:38c8544db6f4 | 78 | - Placed config_functions into ConfigFileIO and added the ability to write the neutral positions to the depth & pitch files |
tnhnrl | 21:38c8544db6f4 | 79 | - Streamlined sub-FSM and Find_Neutral state |
tnhnrl | 21:38c8544db6f4 | 80 | - PID depth and pitch gains have been made into class variables so that they can be resaved to the depth/pitch files |
tnhnrl | 21:38c8544db6f4 | 81 | - Added the ability to save depth & pitch gains and neutral offsets (configfile writes entire file at once) |
tnhnrl | 21:38c8544db6f4 | 82 | - Minor formatting fixes |
tnhnrl | 21:38c8544db6f4 | 83 | - Fixed issue with keyboard function, the keyboard function was continuously active instead of checking pc readable in sit idle |
tnhnrl | 21:38c8544db6f4 | 84 | - Bench tested neutral finding sequence and multi-dive sequence, so far so good |
tnhnrl | 21:38c8544db6f4 | 85 | - Question: Why do we want the keyboard and FSM to run together, specifically allowing the FSM call the keyboard? |
danstrider | 22:a10ee088403b | 86 | Modified 2017-11-22 by Dan |
danstrider | 22:a10ee088403b | 87 | - added ability for substate NEUTRAL_CHECK_PITCH to move the battery toward level, then saves offsets. |
danstrider | 22:a10ee088403b | 88 | - added new entry state NEUTRAL_FIRST_PITCH that also moves the battery toward level, but doesn't save. |
