Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is it possible to detect mouse wheel rotation?

I'm using: PicoMiteHDMI MMBasic USB RP2350A Edition V6.00.02

I am attaching my mouse test program.

mouse_test.zip

If it is possible to detect mouse wheel rotation what does the code for this look like.

No: I haven't found a way to get it working for USB mice

I *really* wanted this to be about a wheel for a pet mouse. I'm disappointed now. :(

I think what you want is the MOUSE SET command. The arguments are:
the USB channel
x-coordinate
y-coordinate
wheel count

so you might use it as:
MOUSE SET 2, Xpos, Ypos, wheel

I've never used this so I'm not sure, but that's how I'd do it according to the manual. Sorry, I have no working example code for you.


EDIT:
Thanks Peter. I assume that was for a PS2 mouse then?

The wheel works for PS2 mice - use the DEVICE(MOUSE 2,W) function

Yes, I can verify that. I use the mouse wheel detecting a lot with my PS/2 mouse.
Didn't knew that it won't work for USB! Hm...
