- 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);
Big update of function flowchart
- add task overview
- add several new classes and functions
Except the fan and motordriver class all current functions are described
in a flowchart
- Add class for controlling fans for cooling the motor drivers
- Add configuration for left and right fan to config.cpp
- Create fan task in main.cpp
- Add getStatus function to controlledMotor class
- Move all separately declared functions in control.hpp to a new class
'controlledArmchair'
- now passing other objects only one time with constructor instead
of accessing them globally
- Create control instance in config.hpp, and passing objects in
config.cpp
- Add functions to new control class
- toggleIdle(): toggle between last mode and idle
- toggleModes(mode1, mode2): toggle between two modes
- Add commands to button.cpp
- 2x button press: call toggleIdle()
- 6x button press: toggleModes MASSAGE -> JOYSTICK
- Define control task in main.cpp
- Adjust button files and main.cpp to use the new command object instead
of the previus functions
Add control.hpp and control.cpp
- task that repeatedly generates motor commands depending on the current mode
- function to change to a specified control mode
Add button.hpp and button.cpp
- class which runs commands depending on the count a button was pressed
Update main.cpp
- create button task
- create control task
- comment out previous testing code
- remove unnecessary includes (already included in config.hpp)
Add control.cpp and button.cpp to CMakeLists
Notes: Tested this state on the armchair: All currently implemented features
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).
- Copy buzzer function from gate project
this makes it possible to easily trigger and queue up buzzing events
without having to worry about delaying the program
- Add instance buzzer to config
- Add code for testing the buzzer to main.cpp
Copy gpio component from gate project
Add instance of evaluatedswitch for button next to joystick to config
Add code for testing the button to main.cpp
- add new function to joystick.hpp/cpp
- reads data from joystick and generates commands for driving in
"joystick" mode
- returns struct with commands for both motors
- main.cpp
- add code for testing the new function
- enable 5v regulator (needed for pullups AB left motor)
- add newly created motorRight to handle function
- add new struct with two motorcommands to motorctl.hpp
- Create class 'evaluatedJoystick'
- evaluates a joystick with 2 analog signals
- scales the adc input to coordinates with detailed tolerances
- calculates angle and radius
- defines an enum with position information
- Add joystick configuration and class instance to config.cpp
- Add code for testing the new class to main.cpp
- Add joystick.cpp to cmakelists
now function `joystick.getData` can be used globally to obtain a struct with
current position data of the joystick
- Create class 'controlledMotor':
- handles 'fading / ramp' of the pwm duty
- handles current limit **not implemented yet**
- has .handle function that is intended to be run very fast in another task
commands are sent via queue
- Create config.hpp
- Globally available instance motorLeft of controlledMotor class
- Create config.cpp
- Configuration of motordriver and control parameters for motorLeft
- Add config.cpp and motorctl.cpp to cmakelists
- main.cpp:
- create 'task_motorctl' which repeatedly runs motorLeft.handle()
- modify testing code for testing the new class
- comments
The fading/ramp capability of the new class was tested successfully
using a breakoutboard with an led.
- Add brief description
- Add installation and compilation instructions
- Add links to websites and connection-plan
- Add planned features
- Add Usage section with usage description of old firmware
- create class 'single100a' in motordrivers.hpp and motordrivers.cpp
- add code for testing the driver in main.cpp (test with led was successful)
- update cmakelists, to also compile the new .cpp file
Rewrite of firmware controlling an electric armchair (previous firmware
developed 2019-2021)
- Init esp-idf project: with esp-idf version v4.4.1 installed ran command `idf.py create-project
armchair`
- Add connection plan from old repo
