modified function
joystickPos_t joystick_evaluatePosition(float x, float y, joystickPos_t* prevPos)
because prevPos has to be stored http.cpp/hpp and joystick.cpp/hpp had
to be updated as well
TODO: add function without hysteresis again?
WIP this has to be tested
Use reference to joystick object in control class instead of accessing
the global evaluatedJoystick object
control.hpp:
- add joystick reference to constructor
- add local joystick pointer variable
control.cpp:
- constructor: copy pointer to joystick object
- use methods of joystick reference instead of global object
- update log output of timeout check
config.cpp:
- add joystick object to control object construction
- joystick.hpp/cpp
- add function joystick_scaleCoordinatesLinear(joystickData_t * data, float pointX, float pointY)
that scales the coordinates with 2 different slopes before and
after certain point
- control.cpp
- scale coordinates linear with new function instead of exponential in JOYSTICK mode
- scale coordinates linear with new function instead of exponential in HTTP mode
- config.cpp
- adjust / decrease http joystick tolerances
Note: tested the armchair in http and joystick mode briefly and
optimized the scaling point slightly
- joystick.hpp/cpp
- add function joystick_scaleCoordinatesExp(joystickData_t * data, float exponent)
which updates joystick data with its scaled coordinates and
re-calculated radius
- control.cpp
- scale coordinates exponential (pow 2) in JOYSTICK mode
- scale coordinates exponential (pow 2) in HTTP mode
- config.cpp
- fixed swapped x/y zero tolerances for hardware joystick
Note: tested armchair with scaling exponents 1.5; 2; 3 and noticed that
2 works best
- add function joystick_generateCommandsShaking that generates motor
commands from joystick data
- pulses motors:
- intervals depend on joystick radius
- direction depends on joystick position (currently only on-x-axis and on-y-axis
supported)
Update react web app:
- add dark background color
- change joystick colors
- increase joystick size by 50px
- change heading
- remove angle and radius
- not displaying anymore
- not sending to api anymore
Update http.cpp:
- remove radius and angle from json parsing
- limit radius to 1
As already did for http joystick:
- Add different config options tolerance zero for X and Y axis for
normal/actual joystick.
This makes it possible to set Y tolerance to a lower value resulting in
a more responsive turning action, with still having a large range around
X axis for turning mode
Fix several bugs noticed while testing the preceding commits in dev
branch:
- Fix bug in function scaleCoordinate
- scaling was wrong resulting in negative/inverted values at start of axis
- Adjust timeout value from 30s to 5min
- Fix http joystick behaivor
- calculate angle, radius and evaluate position AFTER the coordinates
have been scaled in control.cpp (bug introduced when switching applying tolerance
on controller instead of in the app)
- Add independent toleranceZero for X and Y axis -> unnecessary to have
large tolerance for x axis... makes turning more sensitive
- Fix stack overflow in control task
- controller crashed repeatedly when logging output was enabled in
control task
- -> doubled stack size at task creation in main.cpp
currently works, position hast to be evaluated AFTER coordinate scaling
- create new struct control_config_t with several variables previously
hardcoded in control.cpp
- modified constructor: add config parameter
- add definition of config struct in config.cpp
typedef struct control_config_t {
controlMode_t defaultMode; //default mode after startup and toggling IDLE
//--- timeout ---
uint32_t timeoutMs; //time of inactivity after which the mode gets switched to IDLE
float timeoutTolerancePer; //percentage the duty can vary between timeout checks considered still inactive
//--- http mode ---
float http_toleranceZeroPer;//percentage around joystick axis the coordinate snaps to 0
float http_toleranceEndPer; //percentage before joystick end the coordinate snaps to 1/-1
uint32_t http_timeoutMs; //time no new data was received before the motors get turned off
Add feature that switches to mode IDLE when duty of both motors did not
change over certain time.
control.cpp/hpp:
- add private function that handles timeout
- add public function that resets timeout
- add slow loop with timeout handle inside control handle loop
- joystick.cpp/hpp:
- move method scaleCoordinate from joystick class to public function
- modify scaleCoordinate function to accept float values instead of
ADC pin, change tolerance parameters to percent instead of absolute
number
- change method getData to use the public function now
- control.cpp:
- use scaleCoordinate function in http mode
- calculate radius in http mode
- config.cpp
- adjust tolerance thresholds for joystick to percent
- App.js
- disable "snap to zero" feature -> just scale joystick output to
value of -1 to 1
since the web-app runs successfully on the esp32 webserver now, the api
can be accessed directly - this makes the web app independent of the
dynamic controller ip
- remove ip from api url -> uses current host
- add testing code for changing a variable with a button
- comment out some debug output
With this commit the webserver of the controller can serve a folder (/react-app/build/), when the ip is accessed in a web-browser.
Currently the react app is successfully served and the armchair can be controlled when in HTTP mode and connected via AP.
- CMakeLists: Add command that creates and flashes the spiffs partition when running
idf.py flash
- main.cpp: Add function to initialize spiffs
- http.cpp: uncomment handler for default URL (accesses spiffs)
- Add partitions.csv: needed for the creation of spiffs.bin during
compilation
- Add sdkconfig: It was necessary to change the FLASH_SIZE from 2MB to
4MB. To avoid having the same trouble on other devices the sdkconfig
is now added to the repository
- Functional react project which currently provides a web-interface with a
joystick element.
- Coordinates, angle and radius are calculated and sent via http POST request
to an API provided by the esp32 controller (websocket approach was dropped)
- Currently the URL/IP is hardcoded in App.js and has to be changed depending
on the IP-address of the esp32
- control.cpp: Add feature to HTTP mode, that turns motors off when at least one motor is still on
but no data was received for more than 3 seconds (e.g. wifi connection
lost)
- change queue size from 20 to 1 - no need to store multiple joystick
data since only the latest one is relevant
- add "preset command" to control.hpp to set both motors to IDLE
- Create http.cpp and http.hpp
- functions for initializing a http server
- function for URL api/joystick
- receive joystick data from http post request
- parse json, define joystick position (function from joystick.hpp)
- send data to control task via queue
- control.hpp/cpp:
- add HTTP mode to handle loop
- receive joystick commands from queue, generate commands, send to
motorctl
- upgrade changeMode function with ability to run functions at switch
FROM and TO certain modes
- add code to start/stop wifi and webserver when switching to/from
HTTP mode
- change toggleModes and toggleIdle to use the changeMode function
- main.cpp:
- add several sections with code for testing new functions (commented
out)
- add http loglevel
- buzzer.cpp:
- add command (press 4 times) to toggle between HTTP and JOYSTICK mode
FIXME: moved initialization of wifi to main.cpp at startup because of an
error -> resolve this and place wifi start and stop functions into
mode-change as intended
currently works best in accesspoint mode with laptop connected using the
react-webapp
Move section that defines joystick position enum to a separate function
(outside of joystick class), this makes it usable for other inputs as
well
- create new function joystick_evaluatePosition
- call the new function in joystickgetData (where code was initially)
- change function joystick_generateCommandsDriving to accept joystick
data struct instead of joystick object as parameter -> makes the
function usable with other input than hardware joystick too
Create functions in wifi.c and wifi.h:
- an wifi accesspoint can be created
- connect to an existing wifi anf disconnect
Add code for testing to main.cpp:
repeatedly connects, disconnects and switches between AP and connecting
to BKA-network every run
New functions
//init components (run in main function once)
void wifi_initNvs_initNetif();
//function to start an access point
void wifi_init_ap(void);
//function to disable/deinit access point
void wifi_deinit_ap(void);
//function to connect to existing wifi network
void wifi_init_client(void);
//function to disable/deinit client
void wifi_deinit_client(void);

work. You can switch between IDLE and JOYSTICK by pressing the button 2
or 3 times. Also driving works well (limited to 60% duty, with no fans
yet).
