软件调试过程中采用逐步添加模块功能程序的方法，一步步添加各功能模块的应

In the process of software debugging, the method of gradually adding module function programs is adopted, and the application programs of each function module are added step by step, which is gradually modified and perfected. <br>The preliminary software program only displays the time, completes the function of the clock, and then gradually adds bit definitions, completes all the programs related to the key input, realizes the adjustment of the system parameters, and then adds the LCD1602 subroutine to read data to complete the display of the LCD1602 The record of each parameter completes the function of time timing, and finally adds an alarm reminder program to realize the alarm function. <br>In the process of system software programming, it can be divided into the following stages: <br>1. Write a simple clock program to realize the operation of the clock. <br>2. On the basis of the clock, add 2 keys and add a driver to realize its input function, one is a function key and one is an adjustment key; when the function key is pressed, the adjustment function of the adjustment key is enabled; the function key is pressed 1 Times, the adjustment key adjusts the minute; the function key is pressed twice, the adjustment key adjusts the hour; the function key is pressed 3 times, to exit the clock adjustment, the clock starts to run on the adjusted basis. <br>The software used for software debugging is KEIL, which is the most commonly used software for electronic technicians. The version used is KeilμVision4 English version, which is an efficient development application program. This version can also support many of the latest ARM chips.

In the process of software debugging, the method of gradually adding module function program is adopted, step by step to add the application of each functional module, and gradually modify and perfect.<br>The preliminary software program only displays the time, completes the function of the clock, then gradually adds bit definition, completes all the programs related to key input, realizes the adjustable of each parameter of the system, then adds the LCD1602 sub-program to read the data, completes the recording of the parameters displayed in LCD1602, completes the function of time timing, and finally adds the alarm reminder program to realize the alarm function.<br>In the process of system software programming, it can be divided into the following stages:<br>1, write a simple clock program, to achieve the operation of the clock.<br>2, on the basis of the clock, add 2 keys, and add drivers to achieve its input function, one for the function key, one for the adjustment key, when the function key is pressed, enable the adjustment function of the adjustment key, the function key press 1 time, the adjustment key to the minute adjustment, the function key press 2 times, adjust the key to the hour adjustment, the function key press 3 times, exit the clock adjustment, the clock starts to run on the basis of adjustment.<br>The software used in software debugging is KEIL, is the electronic direction technicians to use more software, the use of the version of Keil?Vision4 In English, is an efficient development application. This version also supports many of the latest ARM chips.

In the process of software debugging, we adopt the method of adding module function program step by step, adding application program of each function module step by step, and modifying and perfecting step by step.<br>The preliminary software program only displays the time, completes the function of clock, and then gradually adds the bit definition, completes all the programs related to the key input, realizes the adjustable parameters of the system, and then adds the subprogram of LCD1602 reading data, completes the record of parameters displayed on LCD1602, completes the function of time timing, and finally adds the alarm reminder program to realize the alarm function.<br>In the process of system software programming, it can be divided into the following stages:<br>1. Write a simple clock program to run the clock.<br>2. On the basis of clock, add two keys and add driver to realize its input function, one is function key and the other is adjustment key; when function key is pressed, enable adjustment function of adjustment key; when function key is pressed once, adjust key will adjust minute; when function key is pressed twice, adjust key will adjust hour; when function key is pressed three times, exit clock adjustment, the clock is in Start operation on the basis of adjustment.<br>The software used for software debugging is KEIL, which is widely used by technicians in electronic direction. The version used is keil μ vision4 in English, which is an efficient development application program. This version also supports many of the latest arm chips.<br>
