Hi,
I have noticed my USB mouse pointer moves very fast(more sensitive). Is
there flag or driver ioctl call that i can call from
inputdrivers/ps2mouse/ps2mouse.c to achieve this. I find two defines
PS2_SET_SCALE11, PS2_SET_SCALE21 in the same file. Tried changing the
scaling factor to 2:1. Even then there is no improvement.
Then I tried adjusting/limiting the co-ordinates dx and dy in
ps2mouseEventThread() as
#if 1
if (dx < (-5))
dx = (-5);
if (dx > 5)
dx = 5;
if (dy > 5)
dy = 5;
if (dy < (-5))
dy = (-5);
printf("Mouse output = %d, %d\r\n", dx, dy);
#endif
data->dx += dx;
data->dy += dy;
Though the sensitivity is achieved, it does not give smooth movements, It
causes the mouse pointer to get stuck sometime.
Has any one tried changing this parameter at the driver level ?.
Here is my console output:
