【正文】 es of singlechip microputer. Missile navigation equipment, aircraft control on a variety of instruments, puter work munications and data transmission, industrial automation, realtime process control and data processing, are widely used in a variety of smart IC card, limousine civilian security systems, video machines, cameras, control of automatic washing machines, as well as programcontrolled toys, electronic pet, etc., which are inseparable from the singlechip microputer. Not to mention the field of robot automation, intelligent instrumentation, medical equipment has been. The advantage of using singlechip design software will continue to accumulate, and constantly modular form a standardized software development efficiency greatly improved.Digital Clock Design There are many ways, for example, can be posed of small and mediumscale integrated circuits。 also can be used with a dedicated clock display circuit chips and external circuitry required for the position。 also can be used to achieve singlechip clock. These methods have their own characteristics, including the realization of the use of singlechip programmable digital clock with flexible functions to facilitate the expansion of the clock, which can be issued using the clock control signal, the characteristics of high accuracy. Nowadays, most of the highprecision timing tools use the quartz crystal oscillator. The electronic clock has been made of quartz technology. Its advantage is high accuracy, stability, ease of use, no regular adjustment. Digital clock uses integrated circuits to replace mechanical ponents and LCD to replace indicators to show time. So it reduces the time error. This kind of clock has the function of showing hours, minutes clearly and adjusting hours and minutes easily. The design use MCU to achieve timing function, which is the core ponent ,at the same time use LCD Dynamically displaying hours, minutes and seconds .Compared with the traditional mechanical watches, it has a precise timing , intuitive, and other characteristics. Its timing period is 24hour. This system mainly carries on the research of the digital system takes liquid crystal display, matching with keys to provide friendly customer interface .The digital clock can be continuous and stable working and easy to use.袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇襖羋蕆袇螀芇蕿蝕聿芆艿蒃肅芅蒁螈羈芄薃薁袆芃芃螆螂芃蒞蕿肁節蒈螅羇莁薀薈袃莀艿螃蝿荿莂薆膈莈薄袁肄莇蚆蚄羀莇莆袀袆羃蒈螞螂羂薁袈肀肁芀蟻羆肁莃袆袂肀薅蠆袈聿蚇蒂膇肈莇螇肅肇葿薀罿肆薂螆裊肅芁薈螁膅莃螄聿膄蒆薇羅膃蚈螂羈膂莈蚅袇膁蒀袀螃膀薂蚃肂腿節衿羈腿莄螞襖羋蕆袇螀芇蕿蝕聿芆艿蒃肅芅蒁螈羈芄薃薁袆芃芃螆螂芃蒞蕿肁節蒈螅羇莁薀薈袃莀艿螃蝿荿莂薆膈莈薄袁肄莇蚆蚄羀莇莆袀袆羃蒈螞螂羂薁袈肀肁芀蟻羆肁莃袆袂肀薅蠆袈聿蚇蒂膇肈莇螇肅肇葿薀罿肆薂螆裊肅芁薈螁膅莃螄聿膄蒆薇羅膃蚈螂羈膂莈蚅袇膁蒀袀螃膀薂蚃肂腿節衿羈腿莄螞襖羋蕆袇螀芇蕿蝕聿芆艿蒃肅芅蒁螈羈芄薃薁袆芃芃螆螂芃蒞蕿肁節蒈螅羇莁薀薈袃莀艿螃蝿荿莂薆膈莈薄袁肄莇蚆蚄羀莇莆袀袆羃蒈螞螂羂薁袈肀肁芀蟻羆肁莃袆袂肀薅蠆袈聿蚇蒂膇肈莇螇肅肇葿薀罿肆薂螆裊肅芁薈螁膅莃螄聿膄蒆薇羅膃蚈螂羈膂莈蚅袇膁蒀袀螃膀薂蚃肂腿節衿羈腿莄螞襖羋蕆袇螀芇蕿蝕聿芆艿蒃肅芅蒁螈羈芄薃薁袆芃芃螆螂芃蒞蕿肁節蒈螅羇莁薀薈袃莀艿螃蝿荿莂薆膈莈薄袁肄莇蚆蚄羀莇莆袀袆羃蒈螞螂羂薁袈肀肁芀蟻羆肁莃袆袂肀薅蠆袈聿蚇蒂膇肈莇螇肅肇葿薀罿肆薂螆裊肅芁薈螁膅莃螄聿膄蒆薇羅膃蚈螂羈膂莈蚅袇膁蒀袀螃膀薂蚃肂腿節衿羈腿莄螞襖羋蕆袇螀芇蕿蝕聿芆艿蒃肅芅蒁螈羈芄薃薁袆芃芃螆螂芃蒞蕿肁節蒈螅羇莁薀薈袃莀艿螃蝿荿莂薆膈莈薄袁肄莇蚆蚄羀莇莆袀袆羃蒈螞螂羂薁袈肀肁芀蟻羆肁莃袆袂肀薅蠆袈聿蚇蒂膇肈莇螇肅肇葿薀罿肆薂螆裊肅芁薈螁膅莃螄聿膄蒆薇羅膃蚈螂羈膂莈蚅袇膁蒀袀螃膀薂蚃肂腿節衿羈腿莄螞襖羋蕆袇螀芇蕿蝕聿芆艿蒃肅芅蒁螈羈芄薃薁袆芃芃螆螂芃蒞蕿肁節蒈螅羇莁薀薈袃莀艿螃蝿荿莂薆膈莈薄袁肄莇蚆蚄羀莇莆袀袆羃蒈螞螂羂薁袈肀肁芀蟻羆肁莃袆袂肀薅蠆袈聿蚇蒂膇肈莇螇肅肇葿薀罿肆薂螆裊肅芁薈螁膅莃螄聿膄蒆薇袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿袃薈葿螈聿蒄葿袁羈莀蒈羃膇芆蕆蚃羀膂蒆螅膅蒁薅袇羈莇薄罿膄芃薃蠆羆艿薃袁節膅薂羄肅蒃薁蚃芀荿薀螆肅芅蕿袈羋膁蚈羀肁蒀蚇蝕襖莆蚇螂肀莂蚆羅袂羋蚅蚄膈膄蚄螇羈蒂蚃衿膆莈螞羈罿芄螁蟻膄膀螁螃羇葿螀裊膃蒅蝿肈羆莁螈螇芁芇莄袀肄膃莄羂艿蒂莃螞肂莈蒂螄羋芄蒁袆肀膀蒀罿
