随着科技的发展,人们在日常生活中使用的电器越来越多,电子设备的电磁兼容性(EMC)也越来越重要。所以,人们对电子设备的电磁兼容性的要求也越来越严格,越来越规范。而在市场竞争中,如何降低成本、减少设备体积,是各电子设备制造厂家重点研究的课题。通过对开关电源的EMI滤波电路的类别和相应的技术特点进行分析,设计出一种既能提高性能,又能降低成本的滤波电路。With the development of technology, appliances people use in their daily lives, more and more electronic devices electromagnetic compatibility ( EMC ) has become increasingly important. So, people electromagnetic compatibility requirements of electronic devices have become increasingly stringent, more and more standardized. The competition in the market, how to reduce costs, reduce equipment size, is the subject of the electronic equipment manufacturer focused on research. Through the technical characteristics of the respective category and the EMI filter circuit switching power supply is analyzed both designed to improve a performance of the filter circuit can reduce the cost.

Allegro导出 Gerber文件和钻孔数据文件很多PCB厂家都没有装Allegro软件,所以你不能直接发.brd文件。(很多PCB小厂连ProtelDXP也没有,只支持Protel99)什么是Gerber文件Gerber文件是所有电路设计软件都可以产生的文件,在电子组装行业又称为模版文件(stencil data),在PCB制造业又称为光绘文件。可以说Gerber文件是电子组装业中最通用最广泛的文件格式Gerber文件是EIA的标准格式,分RS274-D和RS274-X两种,其中RS274-X是RS274-D的扩展文件。生产制造部门在条件许可的情况下,应当尽可能要求用户或设计部门提供RS274-X的Gerber文件,这样有利于各工序的生产准备。准备工作为了保证出片的正确性,需要在设计PCB文件之前对一些系统参数进行设置,该设置包括画图的精度,图片的尺寸,动态铺铜的格式。设置画图的精度。在allegro中打开Setup->Drawing Size菜单,调出设置对话框,如图1在对话框中确定User Units选择Mils,Size选择C,这样整个作图区域会大一点,相应的作图范围(Drawing Extents)变为Width:22000.00:Height:17000.00Left X和LeftY为原点坐标。Accuracy选择2,其他根据你的尺寸自行定义。设置完成选择OK按钮,使配置生效。

程序结构 STEP 7为设计程序提供三种方法。基于这些方法,可以选择最适合于你的应用的程序设计方法。 线性化 线性化编程: 所有的指令都在一个块 (OB1) 内。模块化 模块化编程: 每个设备的控制指令都在各自的块内。 OB1按顺序调用每个块。 结构化 结构化编程:不同的块调用可重复利用的代码。 OB1 (或其他块) 调用这些块并传递相应的参数。

This manual documents the Microcontroller profile of version 7 of the ARM® Architecture, the ARMv7-M architecture profile. For short definitions of all the ARMv7 profiles see About the ARMv7 architecture, and architecture profiles on page A1-20.ARMv7 is documented as a set of architecture profiles. The profiles are defined as follows: ARMv7-A The application profile for systems supporting the ARM and Thumb instruction sets, and requiring virtual address support in the memory management model. ARMv7-R The realtime profile for systems supporting the ARM and Thumb instruction sets, and requiring physical address only support in the memory management model ARMv7-M The microcontroller profile for systems supporting only the Thumb instruction set, and where overall size and deterministic operation for an implementation are more important than absolute performance. While profiles were formally introduced with the ARMv7 development, the A-profile and R-profile have implicitly existed in earlier versions, associated with the Virtual Memory System Architecture (VMSA) and Protected Memory System Architecture (PMSA) respectively.

一建立STM32cubeMX工程1.建立新工程,选择芯片STM32F302CCTx2. 在Pinout 中时钟配置为高速外部时钟, UART配置为异步通信, cube 会自动分配引脚。3.Clock Configuration 中配置如下4.configuration 中点击USART1可进入配置在USART1 configuration 中Parameter Settings 可以配置波特率,发送数据字长,奇偶校验位和停止位等。NVIC Setting 可以配置中断优先级。5.生成keil 软件代码点击工具栏中的齿轮按钮,可以选择代码的开发平台, ok 结束。(文件保存路径一定要是全英文的)进过了我们一系列的配置, cube 会为我们自动生成keil 软件的代码,代码中包括工程所需的固件库,配套的头文件,启动文件及用户文件。在main.c 中包括了我们工程所需外设的初始化,包括了系统时钟初始化,中断初始化, GPIO初始化, USART1初始化, HAL库初始化。我们只需要在main.c 中添加我们自己的代码就可以了。二keil 软件代码及HAL库使用UART_HandleTypeDef huart1;生成的代码中有声明一个USART处理的结构体HAL库中串口的数据收发有四个函数HAL_StatusTypeDef HAL_UART_Transmit(UART_HandleTypeDef *huart, uint8_t *pData, uint16_tSize, uint32_t Timeout);HAL_StatusTypeDef HAL_UART_Receive(UART_HandleTypeDef *huart, uint8_t *pData, uint16_tSize, uint32_t Timeout);指针huart 指向我们之前定义的USART处理结构体, 我们将在函数中对结构体中的参数进行操作。pDate 是我们自己定义的数据发送接收缓存, Size 发送接收数据个数, Timeout 超时持续时间。UART状态的结构体:我们在发送接收函数中要经常对USART的状态进行判断,以便我们对函数结构体中的参数进行操作

1、下载FATFS R0.13a的源码2、将下载到的源码全部替代工程里面旧版FATFS, 四个源代码文件,其中 diskio.c 不要加入工程,因为其核心函数被加入了 usbh_msc_fatfs.c3、根据实际使用情况修改ffconf.h 里面的宏开关选项,与旧版不同的部分列出如下:#define FF_CODE_PAGE 936 // 简体中文#define FF_USE_LFN 3 // 允许长文件名,工作缓冲放在 HEAP,因此我在工程选项中把HEAP size 设为了0x1000#define FF_FS_EXFAT 1 // 允许支持 exFAT 文件系统#define FF_LFN_UNICODE 1 // 长文件名支持 Unicode in UTF-16 (TCHAR = WCHAR)4、基本上到此可以编译了,编译过程中会出现各种错误,主要新版没有完全向下兼容的原因引起,根据不同情况针对性解决后,编译OK 比如, f_mount 调用,等等 if ( f_mount( &fatfs, "", 0 ) != FR_OK ) { 。。。} // Fatfs0.09升级到0.13后,形参变化了

MotioninterfaceTM is becoming a "must-have"function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in applications such as gesture commands for applications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in applications ranging from health and fitness monitoring to location-based services. Key requirements for Motionlnterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability-all at a low consumer price point.
