- outsource global variables and objects
- move from config.hpp to global.cpp / hpp
- rename config.hpp, thus change all includes
- re-arrange includes -> in source files instead of header
- optimize / make function comment titles more consistent
- optimize comments overall
- add several temporary files to gitignore
- fix unused variable compiler warnings
- guide-stepper:
- add queue to send commands to stepper-ctl task
- add function that tells stepper task to move to zero
- increase travel length full axis length 110
- control: move guide to zero at reset
- Cmake: enable colored output
new driver works well while testing with one button with debug output
- small changes to isr function that made it fully functional!
- add stepper debug task
- minor optimizations necessary
Partially implemented stepper driver as planned in diagram
works partially (reset button toggles distances)
major issues though - wip
needs debugging and testing
basic task for controlling the stepper
(no accel / decel etc)
works at current speed settings but long moves trigger watchdog
so dropped this idea and using timer as before
- Add stepper driver code from scratch
- Remove / comment out code that used DendoStepper library
- Test custom driver with buttons (guide-stepper.cpp)
untested limited features
- decrease home speed
- invert direction in stepper test and home function due to changed
wiring
- stretch travel steps calculation to multiple steps and variables for
better overview and debugging
- prevent partial steps from being lost -> fixes rounding issue
TESTED: works in general, but steper movement is too jerky. Also there
is a Hardware issue: When VFD/motor is on the steper does not work
properly -> 50ohm pullup near stepper driver fixed this
- optimize some variable and macro names
- change/add function that travels guide certain steps
- stepper task: - calculate steps depending on encoder steps
- move steps if at least 1 step possible
- prepare poti modifier
-> untested
- Add datasheets of VFD and stepper driver
- Change pins in config for stepper driver
- DISABLED LAMP (pin now used for stepper)
- update connection plan with stepper section and wiring
- add static type to all local variables in every source file
so the scope of each variable is limited to that file.
This prevents conflicting variable names with other source file
(e.g. 'state' variable in vfd.cpp)
- simplify encoder concept
wrap all used functions from rotary_encoder.h library in
custom encoder.hpp file
-> only one file has to be included where encoder is used
-> global variable 'encoder' is not necessary anymore
-> reduces duplicate code for length calculation
- update all files where encoder functions where used accordingly
To be able to use the encoder in future stepper task as well
- make certain variables global
- initialize encoder in main
- outsorce encoder functions in encoder.cpp / h
- adjust config
- add macro variable STEPPER_TEST (config.hpp)
if set: only `task_stepper-test` is started (main.cpp)
- add file for stepper/guide related code (guide-stepper.cpp/hpp)
currently defines a task that simply moves the axis left to right
repeatedly with a speed defined by a potentiometer connected to ADC
GPIO34
- Basic lamp functionality: simply turn on when not in COUNTING or TARGET_REACHED
state
- Remove unnecessary comments, fix code formatting in several files
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
- 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
- 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
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
vfd: extend vfd_setState function with direction enum (default fwd)
main: reduce log output from buzzer task
config: use mos1 as vfd_FWD output
control:
add MANUAL state: motor can be controlled via preset buttons
adjust code slightly to support new state (also see updated
function-diagram)
Add readadc function from armchair project
Rework display section
- show lengthNow on first display
- show lengthTarget on second display
Prepare for statemachine
Remove unneeded function
Add comments improve structure
- move code from testing task to control.cpp
- outsource functions for initializing display and encoder
- delete testing code
- add two display pages (current distance and counter)
- run handle functions for each button
Add config.cpp/hpp
- macros for all input and output pins
- gloabl evaluated switch objects
- buzzer object
- display config
- encoder config
Move main.c to main.cpp and adjust code to be c++ compatible
add custom library evaluated switch (copied from armchair project)
add buzzer object (copied from armchair project)
add control.cpp/hpp with control task (no function yet)
