Thanks for great article. I’ve made some improvements on the autoit code to emulate the doubling of mickey / pixels ratio when mouse speed go over a certain value (needed for large movements). In my case, value readed is divided by two (no change from original code) when absolute value is under 40 and mulitiplied by two when > 40 (the modification). This allows faster displacements when joystck is at its max.

Original code
$temp = _CommReadByte(1)
$moveX = ($temp – 63) / 2

$temp = _CommReadByte(1)
$moveY = ($temp – 63) / 2

$mouse = MouseGetPos()

Is replaced with :
$temp = _CommReadByte(1)
$moveX = ($temp – 63)

if ( ($moveX > 0) and ($moveX -40)) Then
$moveX = $moveX / 2
else
$moveX = $moveX * 2
EndIf
$temp = _CommReadByte(1)
$moveY = ($temp – 63)

if ( ($moveY > 0) and ($moveY -40)) Then
$moveY = $moveY / 2
else
$moveY = $moveY * 2
EndIf

$mouse = MouseGetPos()
