Step S21: keyboard filter driving obtains keyboard input data from system, obtains in data entered from the keyboard current Keyboard input information；
In the present embodiment, after PS2 keyboard sends PS2 keyboard input data to controller, system takes from controller PS2 keyboard input data out, and processing is carried out to the PS2 keyboard input data of taking-up and generates keyboard input information, and by keyboard Information preservation is inputted into keyboard input data.After keyboard filter, which drives, sends Simulation of keyboard input data to controller, System takes out Simulation of keyboard input data from controller, and carries out processing to the Simulation of keyboard input data of taking-up and generate keyboard Information is inputted, and keyboard input information is saved in keyboard input data.
Specifically, keyboard filter drives the current keyboard input information obtained in data entered from the keyboard to be specially KEYBOARD_NIPUT_DATA structured data.
For example, KEYBOARD_NIPUT_DATA structured data is as follows:
USHORT UnitId；The corresponding position digital of // keyboard equipment
USHORT MakeCode；// key scan code, i.e. key value
USHORT Flags；// the first marking keys
Wherein, the corresponding Unitld value of PS2 keyboard is 0；It include non-expanding key and expand on PS2 keyboard, when non- Flags=0 in the keyboard input information obtained after system processing when expand is pressed, when non-expanding key bounces at system Flags=1 in the keyboard input information obtained after reason；In the keyboard input information obtained after system processing when expand is pressed Flags=2, Flags=3 in obtained keyboard input information after system processing when expand bounces.
In the present embodiment, it is defeated inside the marking keys Flags in current keyboard input information current keyboard to be also recorded Enter the corresponding key-press status value of information.
Specifically, the corresponding key-press status value of current keyboard input information is the first bit digital in the first marking keys Value.For example, the value of the first marking keys is that (0 binary number is 00 to Flags=0, the first digit in current keyboard input information The value of word be 0) or Flags=2 (2 binary number be 10, the value of the first bit digital for 0) when, corresponding key-press status value is 0；The value of the first marking keys is that (1 binary number is 01 to Flags=1, the value of the first bit digital in current keyboard input information For 1) or Flags=3 (3 binary number is 11, and when the value of the first bit digital is 1), corresponding key-press status value is 1.
For example, obtaining keyboard input information after system is handled when the alphabetical a on PS2 keyboard is pressed, system will Keyboard input information is saved in keyboard input data, and keyboard filter driving obtains keyboard input data from system, from keyboard The corresponding current keyboard input information obtained in input data is as follows:
UnitId=0；
MakeCode=0x1e；
Flags=0；
When the alphabetical a on PS2 keyboard is bounced, keyboard input information is obtained after system is handled, system is by keyboard Information preservation is inputted into keyboard input data, keyboard filter driving obtains keyboard input data from system, entered from the keyboard The corresponding current keyboard input information obtained in data is as follows:
UnitId=0；
MakeCode=0x1e；
Flags=1；

Specifically, keyboard filter driving judges whether current keyboard input information is interference information, specifically: keyboard filter Driving judges whether there is information corresponding with current keyboard input information record, is then for interference information, is not otherwise interference Information.
Step S23: keyboard filter driving judges whether the second marking keys that itself is saved are default marking keys, are then Current keyboard input information is saved in corresponding position in keyboard input data；It is no to then follow the steps S24.
For example, default marking keys value be 0, keyboard filter driving judge itself preservation the second marking keys whether be Default marking keys, specially keyboard filter driving judges whether the value for the second marking keys that itself is saved is 0.
Step S24: keyboard filter driving is corrected in current keyboard input information according to the second marking keys itself saved The first marking keys, by itself save the second marking keys be updated to default marking keys, by the current keyboard after correction Input information preservation corresponding position into keyboard input data.
Step S25: keyboard filter driving judges whether the second marking keys that itself is saved are default marking keys, are then Step S26 is executed, otherwise will be removed in current keyboard input information data entered from the keyboard.
For example, default marking keys value be 0, keyboard filter driving judge itself preservation the second marking keys whether be Default marking keys, specially keyboard filter driving judges whether the value for the second marking keys that itself is saved is 0.
Step S26: keyboard filter driving updates itself according to the first marking keys in current keyboard input information and saves The second marking keys, and will be removed in current keyboard input information data entered from the keyboard.
Optionally, in above-mentioned steps S24, keyboard filter driving corrects current key according to the second marking keys itself saved Disk input information in the first marking keys, specifically: keyboard filter driving by itself save the second marking keys value with The value of first marking keys is added, and updates the first marking keys using operation result；
For example, the value for the second marking keys that keyboard filter drives itself to save is 2, obtained in data entered from the keyboard Current keyboard input information are as follows:
UnitId=0；
MakeCode=0x1e；
Flags=0；
I.e. the value of the first marking keys is 0, and the corresponding key-press status value of current keyboard input information is 0, and keyboard filter drives It is dynamic to be added the value 2 of the second marking keys with the value 0 of the first marking keys, current keyboard input letter is updated using operation result 2 The first marking keys in breath, the value of the first marking keys is 2 after update, and the current keyboard input information after correction is as follows:
UnitId=0；
MakeCode=0x1e；
Flags=2；
The value of the first marking keys is 2 in current keyboard input information after correcting, and corresponding key-press status value is 0；
Correspondingly, in step S26, keyboard filter driving is updated according to the first marking keys in current keyboard input information The second marking keys that itself is saved, specifically: the value of the first marking keys is subtracted current keyboard and inputted by keyboard filter driving The corresponding key-press status value of information updates the second marking keys of itself preservation using operation result；
For example, the second marking keys that keyboard filter drives itself to save are default marking keys, marking keys are defaulted Value 0, the current keyboard input information that keyboard filter driving obtains are as follows:
UnitId=0；
MakeCode=0x35；
Flags=3；
The value of the first marking keys is 3 in current keyboard input information, the corresponding key-press status of current keyboard input information Value is 1, and the value 3 of the first marking keys is subtracted corresponding key-press status value 1 by keyboard filter driving, more using operation result 2 New the second marking keys itself saved, that is, the value of the second marking keys is 2 after updating.
