- add mutex around mutex send instruction
- add minimum delay between sent messages
- detect situation where both motors are off and send special both motor
stop command. This might fix issue "right motor stay always on"
- move speedsensor files from motorctl pcb to common
- single pcb create and configure global speedsensor objects
- display: create fast slow veryslow loop
- clear display every 30s
- show speed in rpm and km/h
NOTE: speedsensor needs fix, direction unreliable
slightly rework hacked display test
- new code structure
- split code in several functions
- add task for display instead of running it in main()
- functions to convert voltage to battery percent charged
- show percentage and voltage on display
Successfull test drive with new driver
- set max duty from 90 to 100
- config adjust fading, calibrate joystick, disable deadtime
- disable 1x button cmd
- 8x sport mode: toggle accel not decel
- make motorctl compatible with different drivers
- pass set function instead of specific motor object
- add lambda function in config.cpp
- update config to use one new sabertooth driver instead of two single100a
- main test controlled motor
Same reason as before commit
Note: some changes to http were necessary due to global object
- untested!
Also remove unneded duplicate components folder
since board_single uses mostly the same code as board_control and
board_motorctl several files are outsorced to common folder to prevent
dupliate code and different versions
New controller will be run with single controller at first...
get single board version from V2.0 and create new folder
(two boards version is kept)
-> copied firmware from e6e586e5855d81ee726bb9a0fbe8ab12def5eeef
successfully read rotational speed and direction using encoder disk and
optical sensor
custom implementation of incremental encoder using gpio edge interrupt
brake-mode support
in BRAKE state relays are powered that connects a brake resistor
(not tested with actual motors)
Also brake mode is currently not used at all
[untested]
Turn on brake relays in BRAKE state
Also wait certain time for relays to switch before shorting the driver
Add config option for brake relay pin
Initialize pin in constructor
Add 2x brake relay
Add 2x optical sensor for speed measurement
-> not enough ports available!
-> Split pin assignment in two pcbs connected via UART
Note: just built and soldered both bords as currently described in connection plan
(old board replaced)
currently handles encoder connected to pins configured in encoder.hpp
and receives and logs all available events in encoder task
Works as expected
TODO: migrate with previous implementation of commands in button.cpp
Same functionality as previous commit. But way more stable and clean.
Previous proof of concept approach had issues with random partial or
too large messages due to time based method
Rework send and receive functions to work more stable
- send: encode data with frame (start, end byte)
- receive: read each byte one after the other, assemble message,
handle actual data in handle function
- add semaphore to write operation to prevent parallel write of
different data when called from other tasks
- board_control successfully sends motor commands to board_motorctl
- board_motorctl receives and applies motor commands
note: control pcb currently switches to HTTP mode after startup for testing
with data from ui
- partially commented in code that has to be reworked
- control: send commands via uart instead of to motor objects
- board motorctl handled motor: add timeout when no target data
received (e.g. control pcb offline / uart bugged)
- board motorctl uart: receive motorCommands_t struct and apply data to
target state of handled motors
- types: fix issue with global motorstateStr variable
- outsoruce common files and separate common types from source files (new
common/types.hpp)
- split source files to 2 board folders (relevant only, no duplicate)
- currently boards compile successfull but not functional at all
- comment out currently incompatible code
board_control currently sends a scruct with incrementing values
board_motorctl receives the struct and logs it
also test code for sending, receiving and returning single value
- add second pcb board_control, currently copy of previous board
- not enough pins -> board_control handle ui send motorcommands via uart
board_motorctl handle motors
add config option for minimum time motor has to be in IDLE before
changing direction. Try to prevent drivers from obvious extreme
overload. At least prevent full speed switch
Untested but simulated via log output
went trough all current files:
- remove old comments
- change structure / newlines
- main.cpp: outsource loglevel function
- http.cpp: FIX compiler warnings
currentsensor.hpp
- add currentsensor class
- add current limit to motorctl handle function
- add config options for curring limit for each motor
- update connection plan with more detailed driver-box overview
- with new hardware noticed that sometimes switch gets triggered x1
randomly when driving forward (EMI ?)
- increased delay options (less responsive but more controlled)
- joystick command generation:
- also remove min duty offset with changing ratio
- prepare threshold where ratio snaps to max for easier turning
-> issue with driver has to be fixed first
- minor motordriver optimization / add commented out debug mode
(driver forward in idle)
- uncomment coordinate scaling which caused unwanted behaivor
especially that radius never got to 1 when joystick diagonal
resulting in loss of power/speed in curves
- now scaling radius only which is the desired functionality
- optimize debug logging
- fix joystick calibration config (invertion was mistaken)
