Add feature and config option #define TARGET_LENGTH_OFFSET
that makes it possible to set a distance that gets added to the target
length, thus preventing falling short on the actual length when spools
rotates back slightly after stop.
Also move reached tolerance to config.
Add add cad files of all designed and 3d-printed parts.
Mostly Freecad and a few older SolidEdge files (_SE)
Add wire-labels.fods containing the printed labels for wires in
control-box and switching cabinet
Add docs folder with relevant images and datasheets of the used components
- Pending auto cut (countdown) can be canceled using any button on the
panel
- Reset button does not reset the length when countdown cancledo
- Fix bug where display did not initialize correctly after start some
times
-> simply init again after welcome msg
- reduce countdown time by 500ms
Update connection plan to match the actual current wiring
Add page to connection plan which describes which cables are connected
between what components
- Basic lamp functionality: simply turn on when not in COUNTING or TARGET_REACHED
state
- Remove unnecessary comments, fix code formatting in several files
Fix bug where display is stuck when countdown stopped via reset button
Add functionality to stop countdown via turning auto-cut switch off
Fix display priority issues with using 2 boolean variables and a delay
before counting
While testing the machine with current firmware, a few parameters got
slightly adjusted:
- dynamic spped lvl later slow
- longer slow speed at start
- less threshold for stying in target reached
- decreased countdown beep interval at auto cut
- adjusted display interval in manual mode (faster)
control.cpp:
- Add new systemState CUTTING
- change systemState_t from enum to enum class (conflicting with
cutter enum)
- Add CUTTING functionality to CUT switch and auto cut after target
reached if enabled
cutter.cpp:
- Add function cutter_isRunning()
config:
- Add GPIO_LAMP macro to config
=> tested system with new stripboard and actual hardware: system
works as expected with new all combinations of the 4 switches
connected to 1 adc
- Adjust lookup voltage for switch combinations, after connecting the
stripboard to actualy used pcb (apparently there was a >100
difference using an other adc channel + pcb)
- define loglevel for analogswitches to WARN
Rework config.cpp and config.hpp:
- different naming convention for evaluated switch objects
- thus updated macros for switches
- add new evalswitch instances for 4 switches on 1 adc
- update switch assignment, use the 4 new inputs
Update connection plan with new assignment, add stripboard details
switchesAnalog:
- Add functions for obtaining states from each switch
- Remove public handle function, (now run locally at each state request of
a pin)
- adjust main.cpp to work with new functions
evaluatedSwitch component:
- remove duplicate code for inverted and non-inverted mode
- add new constructor for instance with a function to obtain current
input state instead of gpio pin (e.g. needed for 4switches on analog input)
- create new files with code for demultiplexing the 4 switches from the
one analog signal
- define lookup table with measurements done with the build pcb, test
switches and esp32 breakout board
- add note do config that gpio used for digital in is now used for
this multiplexer
- main.cpp: disable control task, run new handle function in a loop for
testing
Add details and calculations for a stripboard with a resistor network that makes it
possible to connect 4 switches (to gnd) to one adc pin of the controller
- use evaluatedSwitch class for position switch instead of reading gpio
directly because it triggered incorrectly too often
- cutter_stop() only switch to CANCELED when not in IDLE already
Add encoder test:
- used for calibrating the length measurement by counting the steps
per meter
- enabled with #define ENCODER_TEST in config.hpp
- display1: enocder steps
- display2: converted length in meter
Distance conversion:
- defining STEPS_PER_METER instead of MEASURING_ROLL_DIAMETER in
config.hpp
- defining the steps per meter by issuing 3 test measurements with
4mm2 solar cable in the new encoder test mode
Already switched earlier, now optimized code and connection plan to work
best with new vfd (T130750W).
Previous 7.5kw vfd will work too without using all 7 speed levels as at
first.
connection plan: changed pin assignment (1 free pin)
Code:
- vfd.cpp, main.cpp: remove not used D2 pin (only used with 7.5kw vfd)
- config.hpp: change pin assignment
- Add method to trigger blinking of the display for a certain count and durations
also with a optional off-string
- Add 3x blinking after applying a new target length with preset or set
buttons
- in manual mode blink between 'manual' and lvl+direction indication on
display 2
- when setting custom target length only blink value not "soll"
- reduce brightness from 12 to 8 because of high display temperature
Fix bug in display library where random chars were written to display even
though the array has ended.
Resulting in random character appearing briefly when only first display got written.
-> stop loop when 0-termination of char array is reached
To abstract rather complex functions for 7 segment displays e.g. blink text, scroll
text... a class was created.
This makes it possible to have 2 instances for displayTop and
displayBottom resulting in no duplicate code
Fix bug where sartup randomly crasehd several times because spi config
was initialized with random data -> init with 0
Fix bug where length now was not truncated resulting in flickerin
Fix bug in welcome message where hello string contained random data
- Fix bug where custom length did not get rounded
- Reduce beeping lengths, remove gap between beep events
- Add hysteresis to custom length selection to prevent unwanted beeps or
flickering display at certain poti positions
- change max loglevel to verbose in menuconfig
- outsource dynamic speed to setDynSpeedLvl function
- reuse function in wind-slow state with limit
- update function diagram to representation of current program
