Why not  :)

This a screen shot of "Total RC Commander" V0.1B:

The application is working but for the moment, the screen is optimized only for a 8" tablet
I suspect the application needs at least 7" to display the information correctly
sorry, no phones  :~ :~

Do you have a tablet ??
Please let me have size and resolution


Time has passed  ::)

Total RC Commander V5.2  is now fully optimized for smartphone

I access it daily using my Motorola Moto G

Hi Kas,

Thank you for useful "Joystick BT Commander" application.
But is it possible to ask you to add option to switch from joystick to simple keys (left, right, forward, backward and stop)?

It could be like:

If "left" key is pressed - send x=-100,y=0
If "right" key is pressed - send x=100,y=0
If "forward" key is pressed - send x=0,y=100
If "backward" key is pressed - send x=0,y=-100
If "stop" key is pressed - send x=0,y=0

Picture is attached :).

In another words, keys will be duplicate leftmost, rightmost, topmost and bottommost joystick's positions.

Hi vlad-sh, welcome to the Forum

This is an analog joystick emulator App
I want to keep this 90KB App as compact and efficient as possible  ;)

A possible workaround is to modify AndroTest V2.0

Code: [Select]
// within getJoystickState:                                  ** not tested **

  if      ((joyY>50)  && (abs(joyX)<25))       {joyX=0; joyY=100;}
  else if ((joyY<-50) && (abs(joyX)<25))       {joyX=0; joyY=-100;}
  else if ((joyX>50)  && (abs(joyY)<25))       {joyX=100; joyY=0;}
  else if ((joyX<-50) && (abs(joyY)<25))       {joyX=-100; joyY=0;}
  else if ((abs(joyX)<25) && (abs(joyY)<25))   {joyX=0; joyY=0;}
  else                                         {joyX=JoyX_ant; joyY=JoyY_ant;}
  JoyX_ant = JoyX;
  JoyY_ant = JoyY;

Also uncheck Options / Joystick properties / Auto return to center

Let me know if it helps
