Writeable and unauthorized copyable keyboard

The present invention relates to a writable keyboard, which combines a user editing function of a program approach with a protection function using a keyboard to provide a writable keyboard in which a user can create desired tools and then download these materials to the keyboard. Connect the keyboard and the main board of the main body to the connector to send the Kisscan code, and connect the serial and parallel interface that receives the data from the main board to select the connector and the serial / parallel interface to download. It's about a writable keyboard that lets you create tools if you need them and then download them to the keyboard.

In general, a typical keyboard and mouse are known as input devices used in personal computers, and among them, the keyboard may be represented as a system block diagram as shown in FIG. In FIG. 1, the keyboard unit 1 includes a key board 11 having an 8 × 16 matrix form, and a keyboard microprocessor 12 which performs key scan operation and code conversion on keys pressed on the key board 11. The communication with the main board 2 is made by serial communication. The main board 2 includes a keyboard controller 21 and a main microcomputer 22 which receives the code converted from the keyboard controller 21. The keyboard microprocessor 12 of the keyboard unit 1 includes a system memory S1, a word memory S2, a sipe oil M1, a timer counter TC, an input / output interface IO, And clock generators. In the system as described above, the kisscan code KSC generated by the keyboard unit 1 is converted into the system scan code SSC by the keyboard bios in the keyboard controller 21 as shown in FIG. Is converted to the actual use code (AC) through the main BIOS of the. For example, the shape of the kisscan code KSC generated when a key is pressed in the keyboard unit 1 may be represented as shown in FIG. 8.

For reference, the kisscan code as shown in FIG. 8 is transmitted to the mainboard side through serial communication. The transmitted code is converted into a code for distinguishing a keypress from a release, which is known in three types. In addition, the scan code is a code generated when a key is pressed as a make code, and a code generated when a key is released is called a brake code as shown in FIG. 3.

In FIG. 8, the Hangul characters corresponding to the alphabetic characters are used in the order of arbitrary order irrelevant to the lexical arrangement of the consonants and vowels. V, V, E, R, T, V, V, I, O, P, A, S, D, F, V, H, V, V, L, V, V, C, V, V, N, M

When entering Korean characters in such a conventional system, the phonetic sequence of one syllable is input sequentially, so two or three key presses are used to input one syllable. It takes a lot of time to enter a large number of characters. Therefore, it has been known in the past that a skilled person usually hits only 200 to 400 strokes per minute and a very fast person hits about 600 strokes per minute. The reason for this is that it is difficult to escape the limitation of typing speed because, for example, when entering "angle", it is a method of forming one syllable of Hangul syllables in phoneme order such as a ㅏ a. In addition, if you input fast, the typing sequence of letters or incorrect key presses are likely to occur due to a large number of typos. In the meantime, various types of keyboards for quick hits have been released for special purposes, but these quick keyboards are not keyboards currently used by the general public, but newly designed keyboards or modified ordinary keyboards (for example, the space bar is divided into pieces). Although it is used, it is not convenient for the general public because it contains a lot of inconvenience and does not get a great response.

To this end, a syllable that is installed in the keyboard system and converts a keystroke value, which is a keystroke value from the keyboard keyboard, into a motion conversion code, and a syllable that is synchronized using the converted code value of the Hangul code conversion table. A keyboard microprocessor that performs the same motion conversion processing with the Hangul motion main processing program that processes the system, and a memory having the Hangul motion code conversion table and the Hangul motion main processing program used when the keyboard microprocessor performs the motion processing. Korean character input processing system of one syllable simultaneous batter has been developed. However, this type of squeeze method does not simply transmit a make code and a break code to the main board 2 of the main body when the keys entered through the key board (key matrix) are pressed and released. Determine the number and determine whether the combination should be found in the memory (for example, word memory (S2) corresponding to the ROM (ROM)) and includes a portion to bring the corresponding data from the ROM. Therefore, such memory data is a keyboard maker uses a ROM writer to store and supply the data when the keyboard is manufactured. Therefore, the memory data cannot be modified.

The keyboard 11 of the keyboard unit 1 is manufactured by using a membrane or a capacitive switch to reduce the keyboard unit cost. ghost) phenomenon occurs. This ghost phenomenon works as if any key other than the pressed keys is pressed. When manufactured to handle all combinations of keys, it is relatively expensive. Such a keyboard is called an N-key rollover keyboard. An example of pressing several keys simultaneously is a combination of keys (combination of Ctrl + Alt + Delete) called soft boot in a personal computer (PC). In addition, Hangul is always composed of initial and neutral, and in some cases, Jongsung is added. Therefore, unlike English, the order of consonants and vowels is constant, so if the order of these two letters can be processed by themselves, the speed of data input can be improved. Such a method may be a program using a computer or products processed by circuits in the keyboard itself as shown in FIG. 1. In this case, when the program is processed, the user can construct a desired word or sentence using two or more keyboard values at all times, which is an advantage over the hardware processing method. However, in the program processing method, the unauthorized copying of the program becomes a problem and protects it in various ways. As the environment of the computer changes to Windows, the system has a different environment, which causes secondary problems such as print malfunction, system stop, and program abnormal stop. There is a problem. Moreover, if a computer manufacturer adds a unique feature between the keyboard and the computer, the special ROM function attached to the keyboard, in order to protect the program, causes the system to fail and cannot be used on all computers. On the other hand, the dedicated keyboard method has a problem of flexibility that can not edit the words forming an infinite combination according to the application field. In addition, although a socket for mounting a general ROM can be provided outside the keyboard, general users may purchase and install a socket, which may cause problems such as limitations of liability in case of failure due to electrical factors.

It is an object of the present invention to provide a writable keyboard that combines a user-editing function of a program approach with a keyboard protection function to create a user-desired device and then download these materials to the keyboard.

To this end, the present invention connects the keyboard unit and the main board of the main body with a connector and transmits a kisscan code, and the keyboard unit includes a ROM for storing data and a sipeyu for processing the data, the data from the main board on the keyboard. Connect the serial and serial interface provided, and if necessary, use the phrase (where the phrase means using two or more keyboards to create the word or sentence you want. For example, pressing 동시에 ㄱ ＂and＂ ㅇ ＂simultaneously" The word "members of parliament" behaves as it is typed by the user on the keyboard) and then downloads the data to the keyboard through an interface or connector.

A transmission process (S6-3) for transmitting the output key value by the search to the computer main body is performed.

Hereinafter, the operation of the present invention will be described in detail with reference to the drawings.

In the present invention, since the technology itself for storing the key code in the ROM and providing the scan output to the main body is the same as in the related art, a process of downloading the code data through the soft program which is the core technology of the present invention and storing the data in the ROM will be described. In the present invention, an example of the code data value stored in the ROM 17 may include a table already described. However, the present invention downloads the program specified data (also an already described phrase) from the main board 2 through the connector PS2 or the serial parallel interface (for example, RS232-C) 14. In the present invention, the down data is selected from the connector PS2 or the interface 14 when the user-specified idiom is set on the system so as not to be downloaded through the connector PS2 (for example, in the case of a sambo computer, the idiom is used). It is confirmed that the system is designed to be down), so that it can be used in any environment to be downloaded through the interface 14. This data is then level converted to a level recognizable by the keyboard unit 1 via the level converter 15 when it is downloaded through the interface, which is via the output terminal P1 of the programmable interface controller (PIC) 16. Stored at 17. Of course, in order to store the EPIROM 17, the programmable interface controller 16 designates a storage address so that data is stored at the designated address. During this download, even if the key board 11 is operated, the access to the stored code data of the YPIROM 17 is blocked, which is caused by the strobe output signal of the programmable interface controller 16 (for example, through the output stage P2). Output) allows the restriction means 18 to limit the data retrieval request of Y. pyrom via the keyboard microprocessor 12, thereby preventing the data of Y. pyrom from colliding. Of course, if the environment of the keyboard unit 1 and the motherboard 2 coincide, it is possible to store the necessary utilization data in the YPIROM 17 through the keyboard microprocessor 12.

In the case of Figure 6 the present invention is to use the keyboard unit (1) and the main board (2) connected to each other by the connector (PS2) when the user wants to set the utilization (if you operate the keyboard 11) keyboard Microprocessor 12 provides code instructions to the motherboard. In this case, the motherboard may reject it (the power is cut off or an error message is displayed by the method of rejection). In the case of the rejection, the present invention may separately download the code storage unit 13 through the interface 14. There is a characteristic to function. Of course, when not rejected, it is not necessary to connect the interface separately, so that the utilization tool is stored and used by the operation of the keyboard microprocessor 12 (preparation process S0). In this case, the keyboard microprocessor 12 checks whether there is an interrupt signal, whether there is data transmitted from the motherboard 2, and if there is no data transmitted, performs a normal kiss canning (S6). (First process S1). If there is data transmitted in the step S1, it is checked whether the transmitted code value is a reserved special code (second step S2). If the code is reserved in the second process (S2), the third step of stopping kiss canning, downloading data and returning to the first process (S1), performing kiss canning and returning to the first process if it is not a reserved code; Perform process S3. In this case, if the flag is true, the data from the main board 2 is downloaded. If the flag is false, the kiss can be performed. In the second step S2, if the code flag is true, the code flag is true, and if true, the data is stored at the designated address of the memory 17 (fourth step S4). If the flag in the process (S4) is not true, the flag is interpreted as a command (for example, a reset) transmitted from the motherboard 2 to the keyboard unit 1 to perform a corresponding processing routine, and the first process ( Return to S1).

When there is no data transmitted in the first process S1, the scanning process shown in FIG. 7 is performed. The scanning process includes a sensing process S6-1, a search process S6-2, and a transmission process S6. -3). In the sensing process of detecting a key operation to be performed (S6-1), when the user operates the keyboard 11, the keyboard microprocessor 12 first checks whether there is a change in the state of the key (S6-11), and the brake is applied. If present, the key buffer data stored in the keyboard microprocessor is stored in the temporary buffer (S6-12). If there is no break, the kit value is added to the key buffer (S6-13).

Subsequent to the detection process S6-1, a search process S6-2 is performed. The searching process (S6-2) is a process of checking whether the holding value is a key value following the key value adding process (S6-13) in the sensing process (S6-1) (S6-22), and the sensing process (S6-1). In step S6-21, the key values copied into the temporary buffer are key-aligned to search for a key value matching the key combination of the ROM data (table).

Subsequent to the searching process S6-2, the transmitting process S6-3 is performed. The transmission process stores the output key value when the matching kit value is found in the search process (S6-2) (S6-31), and if the key value is not found in the process (S6-22), the key buffer. In step S6-32, the stored key values are output following the steps S6-31 and S6-32, and the process returns to the initial detection step S6-1 (step S6-33). )), If it is not outputted, it is being outputted, so a process of transmitting key values to the main board 2 of the computer main body (S6-34) is performed.

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention stores a key code in a keyboard having a memory to output a code corresponding to a key value through a connector, and also adds a separate serial / parallel communication line to a program when the main body and the system environment do not match. It can be downloaded and stored in the keyboard part, so it can be used universally regardless of the environment, and the user can change the desired boilerplate at any time, and the program method and the keyboard method are combined. If you don't know the saved code, you can't use the tool.
