FIG. 1 is a block diagram of a preferred embodiment of the present invention.

The detailed description of the preferred embodiment is as follows:

Referring to Fig. 1 a preferred embodiment of the present invention. The user can pre-set a button on a certain remote controller. In this embodiment, the user intends to set the "A", "B", "C", and "D" keys on the remote controller 16 as the four direction keys of the keyboard on the data processing system respectively. , the system can store the representative data of the four direction keys into the relative positions of the complementary metal-oxide-semiconductor (CMOS) memory 11 in the system. The CMOS memory 11 is a permanent memory in a data processing system, and its required power can be supplied by a battery, so that its data still exists after the power is turned off. The representative data of a keyboard key generally consists of a Made Code and a Break Code. What is stored in the CMOS memory 11 can only be code making (Make Code) or break code (Break Code), and then make its corresponding break code when sending the representative data of this key to the main system 19 (Host System) later Or code, like this, can save the space of CMOS memory. A general CMOS memory has a space of 128 bytes, of which 64 bytes are used to store system configuration parameters. The other 64 bytes can be used to store user data (in this embodiment, break code (Break Code) or make code (Make Code)). In an IBM PC compatible system, instructions 70h and 71h can be used to store keyboard data into CMOS memory 11.

The representative data of the arrow keys stored in the CMOS memory will be written into a controller 12 via the signal 112 . Controller 12 can be a keyboard controller (Keyboard Controller). For example, the integrated circuit processor element numbered 8042 series. The controller 12 has a random access memory (RAM) 13 and a read-only memory (ROM) 15, and the representative data of the four direction keys can be input from the memory 11 to the memory 13 by using standard 8042 instructions 61h and the like. The standard 8042 has 128 bytes of random access memory (RAM). For example, the instruction 61h can write the data of the memory 11 into the storage space starting from the address 21h of the random access memory (RAM) 13 of the 8042. In the present embodiment, the four direction keys can be sequentially stored in the storage space of 21h～24h (each key only stores a one-byte code (Make Code')).

Each key on the remote has its own code. In this embodiment, A(01h), B(02h), C(03h)... will be taken as examples. Assuming that the user presses the "C" key on the remote control, the wireless signal of the remote control transmits its code to the receiver 17 of the data processing system. The data 113 preliminarily processed by the receiver 17 will be sent to the controller 12 (8042). The format of the data 113 is indicated by the dotted line. Part 116 is the beginning (Header), and the next series of data 118 includes the customer code (Customer Code) of the 16-bit component and the data code of the 16-bit component. This is a unified industry standard and will not be repeated here. If the "C" key is pressed, the data code will be 02FDh (the first eight digits "02" are the data itself, and the last eight digits "FD" are the complement of "02", which is used for error detection).

After the controller 12 obtains the final data code (02H) by filtering, according to the value of "02"H, it can go to the address 23h of the random access memory (RAM) 13 (the code of "↑" input by the user is stored) to read out the code. code. The controller 12 will follow the general user’s processing method of pressing a keyboard key, and send an interrupt signal (IRQ1) to notify the system to receive the key data, and the controller 12 will code the “↑” of the address 23h of the memory 13 through the data line 114 (Make Code) and break code (Break Code) (correspondingly generated) are sent to the XD-bus 18, and the host system obtains the data from the XD-bus 18 via the data line 115. At this moment, the main system 19 completely follows the way that the user presses the key on the keyboard, and treats it as having the "↑" key pressed for further processing (for example, moving the cursor up). Therefore, the present invention allows the user to define the keys on the remote controller to simulate any key on the keyboard of the data processing system, which is equivalent to extending the keys of the keyboard to the remote controller. For example, when playing computer games, the user can define the direction keys on the remote controller, and directly use the remote controller to control the game software without being limited by the keyboard. In addition, the button definitions of the remote control can be changed at any time, and are flexible. In the embodiment, the action of loading the representative data of the defined keys into the memory 13 of the controller 12 from the memory 11 can be completed by the basic input and output system (BIOS), and stored in its power-on self-test (POST) part, so that all remote controllers can The definition of keyboard all stores in memory 13 earlier. The ROM 15 of the controller 12 can be used to store the signal for controlling the conversion of the data signal 113 into the data line 114 .

In another embodiment of the present invention, the representative data of the keyboard keys to be simulated by the user can be stored in the memory of the disk (hard disk or floppy disk) in the form of a file. When the main system 19 receives the key data, it can read out the data of the corresponding simulated keyboard key in response to the key data, and treat it as if the key of the keyboard has been pressed. The principle is the same as that of the foregoing embodiment. The examples illustrate the invention to aid understanding. Those skilled in the industry can make modifications to the present invention, but none of them depart from the protection scope of the present invention.

The present invention has following effect:

Because in the present invention, the keyboard keys are simulated on the remote controller, that is, the keyboard key data stored in the memory is transmitted to the data processing system through the transmission device, and sent by the remote controller keys, which can use the remote controller to complete the keyboard operation at a long distance. The function of the button makes the operation no longer limited by the distance, and this simulation function can be flexibly changed according to actual needs, which is very practical.
