Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
See also Fig. 1, a kind of firmware module 10 that is used on the LCD, electrically connect with memory chip (EEPROM), its composition mainly includes: core processing module 11, key assignments processing module 12, serial communication processing module 13, LCD display module 14, data memory module 15, memory chip communication module 16, wherein, one end of core processing module 11 connects key assignments processing module 12, with the various key assignments that receive and judgement is operated from the user, the other end connects serial communication module 13 respectively, LCD display module 14 and data memory module 15, wherein the other end of serial communication module 13 is used for connecting the software driver 20 of firmware outside, with the communication between realization and SMM and other member drives program, LCD display module 14 is used for the various information after handling through core processing module are presented on the LCD, the other end of data memory module 15 is connected with a memory chip communication module 16, as the plug-in storer of data memory module to be used for storage and call various data, as logo, Chinese and English character library etc.
When the user carries out exercises to the keyboard on the LCD panel, at first carry out key assignments reception and judgement by key assignments processing module 12, key assignments after the judgement can be sent to core processing module 11, core processing module 11 is handled voluntarily and is analyzed according to the state of present display menu and to received key assignments, to determine next step action, promptly call which kind of module: if analysis result need with other software driver of computer system and SMM communication with acquired information, just connect with serial communication processing module 13, and carry out information interaction by the software driver 20 of itself and firmware outside; If analysis result need be selected menu, then connect, and process and result that menu is selected are presented on the LCD with LCD display module 14; If analysis result need call some logo or Chinese and English character etc., then connect, and by plug-in storer, promptly memory chip communication module 16 is obtained corresponding information with data memory module 15.
Above-mentioned three kinds of core processing module 11 are handled the difference action behind the key assignments, can be independently to carry out, also can be two or three carries out successively, as in, content corresponding can be presented on the LCD by LCD display module 14 by serial communication processing module 13 and other software driver 20 of computer system and SMM communication.In this way, LCD firmware module 10 provided by the invention can also be realized the computer system warning function: when abnormal state of affairs has appearred in computer system, as cpu temperature when too high, SMM can initiatively send alarm command, the LCD firmware module is at first made response by its serial communication processing module 13 and core processing module 11 to this, by LCD display module 14 this warning message is presented on the LCD then, or when this firmware module request and computer system communication and computer system not response the time, this firmware module can be by calling the data that are stored in the data memory module, and by display module corresponding warning message is presented on the LCD, with call user's attention.
When the user need use menu on the LCD to select, at first this firmware module can carry out initialized operation, judge then whether the PC that connects this LCD is in off-mode, if, then on LCD, show relevant logo, and finish operation, if not, then show predefined special start character string; Judge that whether the user is by determining key, should can set according to actual needs by definite key, it for example is the directionkeys right button, if judging does not have, then continue to show special start character string, if the judgment is Yes, then display menu and support user select, carry out once more this moment and judge the operation whether PC shuts down, if then show relevant logo, and finish to move, if not, then the button according to the user sends request, if send the not response of request back software driver, then carry out warning function, and the backtrack menu demonstration, if judge that response is arranged, then show correlation parameter, to provide the user further to select, withdraw from this moment if desired, can be by esc key, thus the demonstration of backtrack menu.
In above-mentioned preferred embodiment, its process flow diagram of described warning function can be with reference to shown in Figure 3.When SMM detects that software-driven does not respond or when having other fault, can initiatively send warning message with the form of byte, this moment, firmware module at first carried out the initialization serial ports, accept and store corresponding byte, judge by core processing module whether this byte is end byte then, if not, then continue previous step and accept the also action of store byte, if, then judge whether to be warning message, if then this warning message is presented on the LCD by the LCD display module, if not, then handle as general data.
LCD firmware module in this preferred embodiment, owing to itself carry a core processing module, can the various key assignments of fast processing, and various processing procedures and/or result be presented on the LCD in the mode of bringing in constant renewal in, therefore this LCD display module not only can show various data and picture statically on LCD, but also has the function of dynamic demonstration.
By above-mentioned preferred embodiment, can on general LCD, realize following major function by this firmware module 10:
1. Presentation Function
The operator can pass through the button on the LCD panel, as LEFT, and RIGHT, UP, DOWN, ENTER, 6 buttons of ESC come menu is operated, and the operator can select him item of interest to watch.Wherein, this menu can be multilevel menu.
2. communication function
Clauses and subclauses (temperature, voltage) the selected needs of operator are watched propose query requests with master to SMM, and wait for the response of SMM.And a data of response is presented on the LCD after treatment.
3. warning function
When abnormal state of affairs has appearred in computer system, SMM can initiatively send alarm command, and the LCD firmware module is made response, and shows this warning message.
When the LCD firmware is filed a request to SMM, when SMM did not have response, firmware also can be presented at warning message on the lcd screen, and this warning message can be that temperature is too high according to concrete condition, and voltage is not enough, SMM response timeout etc.
4. under the state of soft-off, show logo.
Just in order to help to understand better the present invention, rather than be used for limiting of the present invention to the description of embodiment.Any those skilled in the art all can utilize thought of the present invention to carry out some changes and variation, as long as its technological means does not break away from thought of the present invention and main points, still within protection scope of the present invention.
