Help with mouse driver, mouse.spin

mynet43

I've been using the mouse.spin driver with a Logitech trackball. It works perfectly.

Recently I had to switch to a different trackball. It works fine except that the plus and minus are reversed for the X and Y axes. So when I turn it to the right it goes left, etc.

Is anyone familiar enough with this routine to tell me how to modify it to work with this setup? I'm using the start, bound_limits, bound_preset, bound_x, bound_y and bound_scales routines.

Thank you for your help.

Try to call the bound_scales methode with negative values for x_scale and y_scale, if these were positve (or vice versa).

Hi Andy,

Thanks for the quick feedback. I like the idea of calling bound_scales with opposite signs on the arguments.

Right now I'm calling it with: mouse.bound_scales(32, 32, 0) to slow the mouse down.

I'll try it with -32, -32 to see what happens. From the comment in the code, it looks like it may work.

Thanks again,

Jim
