GUI_JoyStick

Simple GUI JoyStick using PySimpleGUI.

How To Use

Make sure you have installed PySimpleGUI in your Python3.

To Try and Check JoyStick

To check, simply run python GUI_JoyStick.py
You will see this window;

The JoyStick Pad, shown as cyan circle, will stick to your mouse pointer on left click-down, and back to center on left click-up.
The coordinates at lower left side are written in (X [pxls], Y [pxls]) and (r [pxls], theta [deg]) formats.

To Use In Your Code

To use coordinates in your own code, put GUI_JoyStick.py at the same directory located your code and do like following;

import GUI_JoyStick

js = GUI_JoyStick.JoyStick()

while True:
    js.update()
    print(js.xy_coordinates)
    print(js.rt_coordinates)
    
    if js.close:
        break

In this case, js.xy_coordinates has (X [pxls], Y [pxls]) data, and js.rt_coordinates has (r [pxls], theta [rad]) data, while GUI shows (X [pxls], Y [pxls]) and (r [pxls], theta [deg]).
It's possible to change circle size and pad size, on set js = GUI_JoyStick.JoyStick(r_max=[YourCircleSize], stick_size=[YourPadSize])

How values are set

The origin to calculate coordinates are at the cross point of horizontal and vertical lines shown in UI.
The coordinates values are taken as shown in below;

Example

This is an example to generate a cmd to control 2 wheels, left and right wheels, vehicle.
To do this, we need to tell directions and powers to apply for both wheels.
Copy GUI_JoyStick.py into ./example directory, and Run below to check how it works;

python ./example/ControlCrawlerMotor.py
