Description of the invention (The data transmission of printed information of employees' cooperatives in the Intellectual Property Bureau of the Ministry of Economic Affairs has become increasingly popular. The combination of the above-mentioned electronic notepad function for e-mail transmission and reception, and even the transmission of images is the focus of development. As shown in the first figure, it is a front view of a traditional mobile phone. Due to the size limitation of the mobile phone 100, in addition to the screen 110, the key 120 can only have 0-9 number keys and several function keys arranged on the screen Below 110 (the screen 110 of the new generation mobile phone is getting larger and larger, the space for pressing the button 12 will be even smaller). When you need to enter text other than numbers or send short messages, you can only use the 0_9 number keys to change the other The text is combined with this number key. For example, the number key in key 120, 2 "still contains the English letters a, b, and c. When the user wants to enter" b, ", the user must first know" b , The corresponding number = key is "2", and then press this key three times in a row to get the letter "^" (if Chinese input is added, the input method may be more complicated) If you only input a few texts into your mobile phone, such as when creating a phonebook or short message function, users may still be able to tolerate it. However, if you want to send emails from your mobile phone, you will face a lot of text rotation. If only the fixed keyboard of the mobile phone is used for input, the input action will become tedious and inefficient. Today, the combination of email transmission on the mobile phone has become an inevitable trend. Today, this problem will become a great problem for users.

Description of the invention (In view of the above background of the invention, the traditional input method of mobile phones is extremely inconvenient, and it is necessary to use multi-purpose numeric keys to operate. Today, more and more mobile phone input is bound to occur. For example, the transmission of e-mail is one of the examples. At this time, the input using a mobile phone will become complicated and inefficient. Therefore, the main purpose of the present invention is to By external The belt keyboard is used for inputting the mobile phone. Another object of the present invention is to use the mobile phone's original Multi Media Card (MMC) transmission interface to externally connect the portable keyboard without making other interfaces. Another purpose of the invention is to use the external portable keyboard to facilitate the transfer of data. The portable keyboard provided by the present invention according to the above-mentioned purpose has a multimedia card slot transmission interface, and this interface is a seven-pin interface. The standard interface has multiple keys on the keyboard for easy rotation. The external keyboard also has an independent microprocessor (MPU) and random access memory (RAM). When the MMC interface is inserted into the mobile phone, the mobile phone will first check the plug-in on the MMC interface. If it is an MMC memory card, the MMC service program will be called, otherwise it will enter the external keyboard mode and ^ put the portable external keyboard into the interrupt mode. After the external keyboard enters the interrupt mode, 'the scan of the serial number of the keyboard keys' is then calculated and stored in the external keyboard.

Ming (~~) ~ " ~~ " ~ ^-Random access memory, and then send an interrupt request to the phone. After receiving the interrupt request from the MMC interface, the mobile phone will enter the external keyboard interrupt service program of the mobile phone, and then command the external keyboard to enter the data transmission mode. Then the mobile phone will obtain the key value from the specific random access memory of the external keyboard through the MMC interface, and Put the obtained key value into the buffer memory of the phone itself, and set the external keyboard to interrupt mode again to receive the next data. After the above process, the key values of the external keyboard can be transferred to the mobile phone and displayed on the liquid crystal display screen of the mobile phone, thereby achieving the portable external keyboard input method of the invention. The portable external keyboard of the present invention has an independent microprocessor and random access memory 'so it is a self-contained system. When the mobile phone is connected to this portable external keyboard' and commands the keyboard to enter the interrupt mode, it can be used. In addition, you can use a keyboard to input large amounts of data, such as typing phonebooks or short messages, or even sending e-mails. You don't have to be limited to a few keys on the phone and complicated input methods, so it is much simpler. At the same time, the external keyboard uses the standardized MMC interface, which can share the same interface with the original MMC card. Therefore, it is not necessary to develop a different interface separately, which can achieve multi-function functions.

Material wheel out / person M B Will be transferred to the full-time processing chip 530 into the data for processing. Data wheel out / in processing chip 530 is made by micro-processing. As shown in the figure, ^ s in the ground 500 is controlled and interrupted " The clock signal line, data line, ^ ㈣ 田 处理 说 # 530 can be set as the output module, and the processor 500 will store it in the random access memory ... = send it to the processing chip, and then The data is transferred to the mobile phone (not shown in the figure) through the hidden interface; and when the processing chip 53 is set to the input mode, the key data is transmitted to the microprocessor 500 and stored in the random access memory Body 5 5 0. Then refer to the sixth to ninth pictures, the system shown in these figures is based on The software flow chart and interrupt service routine flow chart of the external keyboard and mobile phone of the present invention. First refer to the sixth figure, which is the software flow chart of the external keyboard. After starting from block 5 95, when the external keyboard and mobile phone are connected, The phone will first check the plug-in on the MMC interface. If it is an MMC card, it will first call the service program of the MMC card, otherwise it will call the external keyboard service program and command the external keyboard to enter the interrupt mode (block 600). When the external keyboard is connected to the phone After the interrupt request, it then enters its own interrupt processing mode (block 6 1 0). That is, the index A in the figure. This paper standard applies the Zhongguanjia standard (CNS) M specification (21Qx297 public attack ----: l · ---- 01 — (Please read the notes on the back before filling this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Consumer Cooperatives 510113 A7 B7 V. Description of the invention () (Please read the notes on the back before filling (This page) Refer to Figure 7 again. This figure shows the flowchart of the interrupt processing mode of the external keyboard. After the external keyboard enters the interrupt processing program, it waits for use. Enter the data. At this time, the interrupt handler will continuously scan the keyboard's matrix circuit (for example, the matrix circuit 540 in the fifth figure) to detect the user's keystrokes and get the serial number of the keystrokes (block 7 00). Calculate the key value according to the key sequence number (block 71 〇), and then store the key value into a specific random access memory (block 7 2 0) under the control of the microprocessor, and then send an interrupt to the mobile phone Request (block 730) in order to send this key value to the phone, and then clear its own interrupt flag (block 740) and return (block 750) to the external keyboard software process to wait for the next key press. ίτ Then return to the sixth figure. After the external keyboard obtains the key values and sends an interrupt request to the mobile phone, the mobile phone will send a command to tell the external keyboard to enter the data transmission mode (block 620), so the external keyboard passes the stored key values through the MMC interface. It is transmitted to the mobile phone, and then the flow proceeds to block 630. It is determined whether the mobile phone should end the data input process. If it is to continue to input, it returns to block 61 〇 '; otherwise, it goes to block 640 to end the software flow of this external keyboard. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Refer to Figure 8 for a flowchart of the mobile phone software. After starting block 795, the mobile phone first checks whether there is a plug-in on the MMC interface (block 800). If there is no plug-in, the software flow ends (block 81), otherwise the flow proceeds to block 82 and it is determined that the plug-in is a OC card or For an external keyboard, if it is an MMC card, then call the MMC service program (block 83), and 10 invention description (if it is an external keyboard, enter box 840, at this time the phone will command the external keyboard to enter the interrupt mode, which is the above external The keyboard continuously detects whether there is a key mode. At the same time, as mentioned above, when the external key has been detected and stored, it will send an interrupt request to the mobile phone, so the mobile phone will receive this interrupt request from the MMC interface (block 8 50) After that, the mobile phone will enter the interrupt service routine of the external keyboard of the mobile phone (box 860), which is the part labeled b. Then refer to the ninth figure, when entering the interrupt service routine of the external keyboard of the mobile phone, the mobile phone first issues a command to the external keyboard, Put it into the data transmission mode (box 9 0 0), and then the phone reads from the specific random access memory of the external keyboard through the Li interface. The key value (box 91 〇), that is, the external keyboard will send the key value stored in its own random access memory to the mobile phone through its own microprocessor. Then go to box 92 and re-send the external keyboard Set to interrupt mode, then put the obtained key value into the key value buffer memory in the phone (block 9 30). Finally clear its own interrupt flag (block 940), and then return to the mobile phone software flow (block 950 ), Waiting for the next entry of data. Return to the eighth figure, after executing block 860 to enter the external keyboard interrupt service program of the mobile phone and obtain the input key value, the mobile phone will call the application program interface to remove the key value in the buffer memory. (Box 8 7 0), and then display it on the LCD screen of the mobile phone. After that, if the mobile phone wants to end this input process, it will return to the end box 81 0, otherwise it will return to box 820 and wait for the next input of data. 11 papers Standards are applicable to China National Standard (CNS) A4 specifications (210X: Z97 mm) (please read the notes on the back before filling out this page) 1 ^-Order the consumption of employees of the Intellectual Property Bureau of the Ministry of Economic Affairs 510113 A7 B7 printed by Zhuozhesha V.
