婴儿出生信息登记系统 .按键1可以录入一条婴儿材料，其中婴儿母亲、婴儿性别和护理人员代码不能为空，其他数据如果需要为空请输入 / 。 2.按键2可以查看婴儿材料保存文件里面的所有婴儿材料。 3.按键3可以通过输入婴儿父母姓名、婴儿性别、婴儿出生医院或者婴儿出生日期进行查找。 4.按键4可以显示超低重婴儿材料，超低重婴儿标准是低于1kg。 5.按键5可以通过输入婴儿编号确定需要修改材料的婴儿，然后可以通过输入所需修改的项目，对婴儿材料除婴儿编号以外的数据进行修改。 6.按键6可以通过输入婴儿编号来确定要删除的婴儿材料。 7.按键7查看使用说明。 8.按键8退出婴儿信息登记系统。-birth registration information system. Press a baby can be an input materials, baby mothers, the gender of babies and nursing staff code can not be empty, the other data if needed to enter the air /. 2. Press two babies can view material inside the preservation of all infant materials. 3. 3 keys can be imported baby names of parents, infant sex, Hospital births or birth date you. 4. Press 4 show low weight babies materials, ultra-low weight babies is lower than 1kg standards. 5. Five keys can be imported baby No. identified the need to amend the material babies, then through the importation of necessary changes, in addition to the infant baby No. materials outside the data changes. 6

本代码介绍了设计模式中单件的使用，请大家多多交流-this code introduce you the mode of single in design software

这是我自己写的一个Gtk+2.18与directfb1.2自动安装脚本，由于源码包太大，下载者自己去下载吧，按脚本的版本找到，解压放到指定位置，运行./install.sh即可自动完成，或者你可以修改脚本。-This is my own to write a Gtk+2.18 and directfb1.2 automatically install script, as the source packages too large to download to download it themselves, according to the version of the script found on the specified location decompression, run./Install. sh can be done automatically, or you can modify the script.

大家都知道ICC-AVR不能进行代码调试，很多人都选择了AVR Studio，但是AVR Studio不直观，特别是在做液晶显示代码调试的时候，不能即时的看到显示的情况，而仿真器又太贵，对大多初学者都不太现实。 今天给大家介绍一种即能像AVR Studio一样进行代码级调试，又可以实时看到MCU状态的软件，Proteus。-We all know that is not ICC-AVR debugging code, many people have opted for AVR Studio, but the AVR Studio is not intuitive, especially in the LCD to do when debugging code is not readily see the display of the situation, and emulators are too expensive for most beginners are not realistic. To tell you today that as a kind of the same AVR Studio for code-level debugging MCU can see the status of real-time software, Proteus.
