隨著科技的發展,人們在日常生活中使用的電器越來越多,電子設備的電磁兼容性(EMC)也越來越重要。所以,人們對電子設備的電磁兼容性的要求也越來越嚴格,越來越規范。而在市場競爭中,如何降低成本、減少設備體積,是各電子設備制造廠家重點研究的課題。通過對開關電源的EMI濾波電路的類別和相應的技術特點進行分析,設計出一種既能提高性能,又能降低成本的濾波電路。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導出 Gerber文件和鉆孔數據文件很多PCB廠家都沒有裝Allegro軟件,所以你不能直接發.brd文件。(很多PCB小廠連ProtelDXP也沒有,只支持Protel99)什么是Gerber文件Gerber文件是所有電路設計軟件都可以產生的文件,在電子組裝行業又稱為模版文件(stencil data),在PCB制造業又稱為光繪文件。可以說Gerber文件是電子組裝業中最通用最廣泛的文件格式Gerber文件是EIA的標準格式,分RS274-D和RS274-X兩種,其中RS274-X是RS274-D的擴展文件。生產制造部門在條件許可的情況下,應當盡可能要求用戶或設計部門提供RS274-X的Gerber文件,這樣有利于各工序的生產準備。準備工作為了保證出片的正確性,需要在設計PCB文件之前對一些系統參數進行設置,該設置包括畫圖的精度,圖片的尺寸,動態鋪銅的格式。設置畫圖的精度。在allegro中打開Setup->Drawing Size菜單,調出設置對話框,如圖1在對話框中確定User Units選擇Mils,Size選擇C,這樣整個作圖區域會大一點,相應的作圖范圍(Drawing Extents)變為Width:22000.00:Height:17000.00Left X和LeftY為原點坐標。Accuracy選擇2,其他根據你的尺寸自行定義。設置完成選擇OK按鈕,使配置生效。

程序結構 STEP 7為設計程序提供三種方法。基于這些方法,可以選擇最適合于你的應用的程序設計方法。 線性化 線性化編程: 所有的指令都在一個塊 (OB1) 內。模塊化 模塊化編程: 每個設備的控制指令都在各自的塊內。 OB1按順序調用每個塊。 結構化 結構化編程:不同的塊調用可重復利用的代碼。 OB1 (或其他塊) 調用這些塊并傳遞相應的參數。

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.

1、下載FATFS R0.13a的源碼2、將下載到的源碼全部替代工程里面舊版FATFS, 四個源代碼文件,其中 diskio.c 不要加入工程,因為其核心函數被加入了 usbh_msc_fatfs.c3、根據實際使用情況修改ffconf.h 里面的宏開關選項,與舊版不同的部分列出如下:#define FF_CODE_PAGE 936 // 簡體中文#define FF_USE_LFN 3 // 允許長文件名,工作緩沖放在 HEAP,因此我在工程選項中把HEAP size 設為了0x1000#define FF_FS_EXFAT 1 // 允許支持 exFAT 文件系統#define FF_LFN_UNICODE 1 // 長文件名支持 Unicode in UTF-16 (TCHAR = WCHAR)4、基本上到此可以編譯了,編譯過程中會出現各種錯誤,主要新版沒有完全向下兼容的原因引起,根據不同情況針對性解決后,編譯OK 比如, f_mount 調用,等等 if ( f_mount( &fatfs, "", 0 ) != FR_OK ) { 。。。} // Fatfs0.09升級到0.13后,形參變化了
