Function；Otherwise interrupted by opening PS2, open PS2 mouse functions, button detection module will continue to obtain key on EC matrix keyboards
Value, until platform shutdown power-off.
Judge whether PS2 touch pads mouse is in running order, is, interrupted by closing PS2, configure complexing pin
PS2 mouse functions are closed for GPIO；Otherwise interrupted by opening PS2, complexing pin is configured into PS2 to open PS2 mouses
Function.
Described method, is concretely comprised the following steps：
After start, EC starts to detect whether the shortcut on matrix keyboard is pressed；
If matrix keyboard shortcut is not pressed, continue to detect；
If matrix keyboard shortcut is pressed, key assignments is obtained, judges whether current PS2 touch pads mouse is in work shape
State, is to be interrupted by closing PS2, complexing pin is configured into GPIO to close PS2 mouse functions；Otherwise by opening PS2
Interrupt, be configured to PS2 to open PS2 mouse functions by complexing pin；
EC continues to detect whether the shortcut of matrix keyboard is pressed, until platform shutdown power-off.
The system that a kind of EC controls PS2 touch pad mouse switches, including button detection module, PS2 touch pad mouse switches
Module,
Button detection module is responsible for obtaining key assignments on EC matrix keyboards, and key assignments is passed into PS2 touch pad mouse switch modules,
PS2 touch pad mouse switch modules take corresponding actions according to current key assignments, judge whether PS2 touch pads mouse is in
Working condition, is to be interrupted by closing PS2, close PS2 mouse functions；Otherwise interrupted by opening PS2, open PS2 mouses
Function, button detection module will continue to obtain key assignments on EC matrix keyboards, until platform shutdown power-off.
The PS2 touch pads mouse switch module judges whether PS2 touch pads mouse is in running order, is then by closing
PS2 is closed to interrupt, be configured to GPIO to close PS2 mouse functions by complexing pin；Otherwise interrupted by opening PS2, manage multiplexing
Pin is configured to PS2 to open PS2 mouse functions.
Usefulness of the present invention is：
The present invention provides a kind of method that EC controls PS2 touch pad mouse switches, and key assignments is obtained on EC matrix keyboards, according to working as
Preceding key assignments takes corresponding actions, judges whether PS2 touch pads mouse is in running order, is, is interrupted, closed by closing PS2
Close PS2 mouse functions；Otherwise interrupted by opening PS2, open PS2 mouse functions, button detection module will continue EC matrix keys
Key assignments is obtained on disk, until platform shutdown power-off；
Using PS2 interfaces PS2 touch pad mouses being connected on EC, by obtaining key assignments on EC matrix keyboards, realize PS2
The function of touch pad mouse switch, the inventive method more brief and practical, completely disengages from the participation of upper layer software (applications), so that more steady
It is fixed, it is less prone to problem.
Brief description of the drawings
The existing PS2 touch pads mouse switch flow charts of Fig. 1；
Fig. 2 PS2 touch pads mouse switch flow charts of the present invention.
Embodiment
The present invention provides a kind of method that EC controls PS2 touch pad mouse switches, and key assignments, root are obtained on EC matrix keyboards
Corresponding actions are taken according to current key assignments, judge whether PS2 touch pads mouse is in running order, is, by closing in PS2
Disconnected, closing PS2 mouse functions；Otherwise interrupted by opening PS2, open PS2 mouse functions, button detection module will continue EC squares
Key assignments is obtained on battle array keyboard, until platform shutdown power-off.
The system that a kind of EC controls PS2 touch pad mouse switches, including button detection module, PS2 touch pads are provided simultaneously
Mouse switch module,
Button detection module is responsible for obtaining key assignments on EC matrix keyboards, and key assignments is passed into PS2 touch pad mouse switch modules,
PS2 touch pad mouse switch modules take corresponding actions according to current key assignments, judge whether PS2 touch pads mouse is in
Working condition, is to be interrupted by closing PS2, close PS2 mouse functions；Otherwise interrupted by opening PS2, open PS2 mouses
