If you button is NOT coded, that isnt too bad. Just dont touch the joystick and let it center itself and push the button. Code would be something like:

if (switchname)
{
consty=p1_y-127;
constx=p1_x-127;
}

and then modify the drive code so it takes
pwmxx= LimitMix((p1_y-consty)+(p1_x-constx)-127);

Good Luck
