单片机PWM控制LED灯渐亮渐灭C51程序

首先介绍了合成孔径雷达(SAR)的特点，然后阐述了合成孔径雷达原理和末精确制导机制。由于合成孔径雷达能全天候、全天时成像，且采用了合成孔径技术，因此SAR图像不论在距离向，还是方位向均具有高的分辨力，这对发展导弹末段数字式景象相关匹配制导有着重要的意义。-First introduced the synthetic aperture radar (SAR) characteristics, and then expounded the principle of synthetic aperture radar and precision-guided mechanism at the end. As a result of synthetic aperture radar can be all-weather, all the time imaging, and use of synthetic aperture techniques, and that SAR images, whether in the distance to, or position to have a high-resolution, which is the development of the missile in the last paragraph of digital image correlation matching guidance has an important significance.

详细描叙arm-linux的配置过程，整个过程都是自己经验总结，还配有大量图片，可供需要的人使用-Arm-linux describes in detail the configuration process, the whole process for his own experience, also has a large number of pictures, for those who need to use

应用背景可以在mfc下直接使用,包括wincewin32平台,该控件根据我之前写过的几个复杂和简单的曲线控件进行了优点综合，专为用于手持仪器触摸平台而设计的。为满足每秒刷新10000点数据的使用要求，对代码做了很多的修改，和效率提升。这可能导致程序代码质量不是很高，但程序框架和代码效果是可以保证的。也是我现在的应用版本。关键技术该控件根据我之前写过的几个复杂和简单的曲线控件进行了优点综合，专为用于手持仪器触摸平台而设计的。采用GDI和静态控件，进行独立封装，能在mfc下直接包含控件相关源代码进行创建，wince和win32平台下都可以用。可以实现图形区域选框放大和双击恢复，数值标记，坐标轴位置改变，坐标轴自动移动等，如果需要功能增强，可少量修改代码，即可完成，如添加多轴、坐标自适应、数据绘制样式改变等。代码中轴跟数据为独立封装，可方便实现数据跟轴的link等。更多的使用，见程序吧。

ARMSYS实验二十四：FAT16文件系统的移植与应用 描述：对Nandflash进行格式化，完成文件系统初 始化，并利用FAT16提供的API函数进行文件操作。 另有：flash_tools，观察nandflash扇区内容的工具-Experimental ARMSYS 24: FAT16 file system and application of transplantation Description: on the NANDFLASH format, the completion of the file system initialization, and use the API provided FAT16 file operations function. Otherwise: flash_tools, to observe the contents of the NANDFLASH sector tools

你可曾经为硬件看门狗的复位时间太短,而苦恼过,这个方法帮你解决问题. 用定时器喂狗,如果超过一定时间(程序跑飞,或整个中断都关闭,都会导致定时器不喂狗,导致看门狗的复位,从而延长了看门狗的复位时间)不喂就复位. 程序中我以lcpRD2为例.-you may have to reset the hardware watchdog short time and anguish that this approach help you solve the problem. DOG with timers, if more than a certain time (running fly procedures, or were closed throughout the interruption, it will not lead to the timer DOG, resulting in the reduction watchdog, thereby prolonging the watchdog reset the time) do not feed on the reset. proceedings I lcpRD2 example.
