PS/2 mouse false interupts

Post by buc030 »

Hey guys,
I'm trying to implement window system to my OS, as part of it I'm implementing a mouse driver...

Anyways, to the point... for some reason I get false input from the mouse, like the bit for left button set when I didn't press it,
or like huge movement values... I've tried to search online but it I couldn't find anything that seems related..
Did anyone encounter this? How can I overcome this (Maybe a way to identify false input and filter it)?

Thanks,
Shai.

It sounds to me like your mouse packets are getting misaligned. There is no way to "filter" bad mouse packets except with sanity checks, but you almost never get a bad mouse datapacket.

There might be a problem with your mouse driver. How about you post the code so we can see it?
