嵌入式FAT16文件系統源碼下載1) 兼容FAT16文件系統，長文件名，最大路徑長度260個字節,符合Microsoft Longfilename specification。 2) 可移植于各種平臺，只需編寫sector驅動驅動，共計兩個函數：1）read_flash_sector() 2）write_flash_sector()。 3) 文件緩沖功能：1）讀文件時，讀位置在文件緩沖區內，則可直接讀文件緩沖區，不需要讀物理磁盤；文件緩沖區大小可使用編譯宏EnableFileBuf，TotalFileBUFsQTYeachFCB，FileBUFSize來控制。 4) 可同時打開多個文件；最大打開文件數可使用編譯宏MaximumFCB設定，MaximumFCB最大值限定為254。 5) 文件保護功能：文件可同時打開多個FCB，而只有其中一個FCB可以得到文件RD/WR權限。該功能完全由文件系統代碼來完成，上層應用無需編寫額外代碼。 6) 所有編譯宏存放于文件fat_cfg.h。

This is a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program. All written in masm assembler. There is also a small 252 byte driver that allows nonstandard floppy formats on dos systems below 7.0. Floppies can be formatted in any track and sector layout. 1.44M floppies can be formatted to 1.76 M. All source code,includes and libraries are included. Modify the bld.bat file to your own needs. There are many asm tricks in the source code. Have fun with this old code.

Currently, the information and communications technology (ICT) industry sector accounts for about 2–6% of the energy consumption worldwide, and a significant por- tion of this is contributed by the wireless and mobile communications industry. With the proliferation of wireless data applications, wireless technology continues to increase worldwide at an unprecedented growth rate. This has resulted in an increased number of installed base stations and higher demand on power grids and device power usage, causing an increased carbon footprint worldwide.

When 3GPP started standardizing the IMS a few years ago, most analysts expected the number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly after that). While those predictions have proven to be too aggressive owing to a number of upheavals hitting the ICT (Information and Communications Technologies) sector, we are now seeing more and more commercial IMS-based service offerings in the market. At the time of writing (May 2008), there are over 30 commercial IMS networks running live traffic, addingup to over10million IMS users aroundthe world; the IMS is beingdeployedglobally. In addition, there are plenty of ongoing market activities; it is estimated that over 130 IMS contracts have been awarded to all IMS manufacturers. The number of IMS users will grow substantially as these awarded contracts are launched commercially. At the same time, the number of IMS users in presently deployed networks is steadily increasing as new services are introduced and operators running these networks migrate their non-IMS users to their IMS networks.

In the present era, low observability is one of the critical requirements in aerospace sector, especially related to defense. The stealth technology essentially relates to shaping and usage of radar absorbing materials (RAM) or radar absorbing struc- tures (RAS). The performance of such radar cross section (RCS) reduction tech- niques is limited by the bandwidth constraints, payload requirements, and other structural issues. Moreover, with advancement of materials science, the structure geometry no longer remains key decisive factor toward stealth.

FLASH實驗-SPI學習目標：1、學會STM32硬件SPI2、學會對EN25Q64進行讀寫操作10.1 EN25Q64簡介EN25Q64是華邦公司推出的大容量SPI FLASH產品，EN25Q64的容量為64M比特，也就是說有8M字節.EN25Q64將8M的容量分為128個塊（Block），每個塊大小為64K字節，每個塊又分為16個扇區（sector），每個扇區4K個字節.EN25Q64的最少擦除單位為一個扇區，也就是每次必除4K個字節。EN25Q64支持標準的SPI，還支持雙輸出/四輸出的SPI，最大SPI時鐘可以到80Mhz（雙輸出時相當于160Mhz，四輸出時相當于320M），更多的EN25Q64的介紹，請參考EN25Q64的DAIASHEET.10.2 SPI簡介從上面的簡介我們知道，EN25Q64是使用SPI來通信的。那什么是SPI呢？SPI是英語Serial Peripheral interface的縮寫，顧名思義就是串行外圍設備接口，SPI接口主要用四根線進行通信：1，MISO：主設備數據輸入，從設備數據輸出。2，MOSI：主設備數據輸出，從設備數據輸入。3，SCLK：時鐘信號，由主設備產生。4.CS：從設備片選信號，由主設備控制。而通常意義上，SPI的通信只用三根線就可以了，一根時鐘線、一根輸出、根輸入。為了更好理解SPI的傳輸原理，我們來看一下SPI的內部結構：從圖上可以有知道，SPI數據的傳輸過程其實是通過一個移位寄存器來完成的，主機將自己的移位寄存器的數據移出，同時從機的移位寄存器數據移入，同時將自己的數據移出。簡單的來理解，就像將兩個寄存器貼在一起，然后進行循環左移或者循環右移（SPI的傳輸可以選擇先發送高位還是先發送低位。），直到兩個寄存器的數據交換為止。而時鐘信號SCLK就是控制傳輸速率的。STM32內部是給我們提供了一個SPI的外設的，那么我們就可以使用單片機的內部的SPI來控制EN25Q64了
