  • P90CL301 I2C driver routines

    This application note shows how to write an Inter Integrated Circuit bus driver (I²C) for the Philips P90CL301micro-controller.It is not only an example of writing a driver, but it also includes a set of application interface software routines toquickly implement a complete I²C multi-master system application.For specific applications the user will have to make minimal changes in the driver program. Using the drivermeans linking modules to your application software and including a header-file into the application sourceprograms. A small example program of how to use the driver is listed.The driver supports i.a. polled or interrupt driven message handling, slave message transfers and multi-mastersystem applications. Furthermore, it is made suitable for use in conjunction with real time operating systems, likepSOS+.

  • 68HC05K0 Infra-red Remote Cont

    The MC68HC05K0 is a low cost, low pin countsingle chip microcomputer with 504 bytes of userROM and 32 bytes of RAM. The MC68HC05K0 isa member of the 68HC05K series of devices whichare available in 16-pin DIL or SOIC packages.It uses the same CPU as the other devices in the68HC05 family and has the same instructions andregisters. Additionally, the device has a 15-stagemulti-function timer and 10 general purposebi-directional I/0 lines. A mask option is availablefor software programmable pull-downs on all ofthe I/O pins and four of the pins are capable ofgenerating interrupts.The device is ideally suited for remote-controlkeyboard applications because the pull-downs andthe interrupt drivers on the port pins allowkeyboards to be built without any externalcomponents except the keys themselves. There isno need for external pull-up or pull-down resistors,or diodes for wired-OR interrupts, as these featuresare already designed into the device.

  • Xilinx UltraScale:新一代架構滿足您的新一代架構需求(EN)

      中文版詳情瀏覽:http://www.elecfans.com/emb/fpga/20130715324029.html   Xilinx UltraScale:The Next-Generation Architecture for Your Next-Generation Architecture    The Xilinx® UltraScale™ architecture delivers unprecedented levels of integration and capability with ASIC-class system- level performance for the most demanding applications.   The UltraScale architecture is the industr y's f irst application of leading-edge ASIC architectural enhancements in an All Programmable architecture that scales from 20 nm planar through 16 nm FinFET technologies and beyond, in addition to scaling from monolithic through 3D ICs. Through analytical co-optimization with the X ilinx V ivado® Design Suite, the UltraScale architecture provides massive routing capacity while intelligently resolving typical bottlenecks in ways never before possible. This design synergy achieves greater than 90% utilization with no performance degradation.   Some of the UltraScale architecture breakthroughs include:   • Strategic placement (virtually anywhere on the die) of ASIC-like system clocks, reducing clock skew by up to 50%    • Latency-producing pipelining is virtually unnecessary in systems with massively parallel bus architecture, increasing system speed and capability   • Potential timing-closure problems and interconnect bottlenecks are eliminated, even in systems requiring 90% or more resource utilization   • 3D IC integration makes it possible to build larger devices one process generation ahead of the current industr y standard    • Greatly increased system performance, including multi-gigabit serial transceivers, I/O, and memor y bandwidth is available within even smaller system power budgets   • Greatly enhanced DSP and packet handling   The Xilinx UltraScale architecture opens up whole new dimensions for designers of ultra-high-capacity solutions.

  • 用MDK生成bin格式的可執行文件

    用MDK 生成bin 文件1用MDK 生成bin 文件Embest 徐良平在RV MDK 中,默認情況下生成*.hex 的可執行文件,但是當我們要生成*.bin 的可執行文件時怎么辦呢?答案是可以使用RVCT 的fromelf.exe 工具進行轉換。也就是說首先將源文件編譯鏈接成*.axf 的文件,然后使用fromelf.exe 工具將*.axf 格式的文件轉換成*.bin格式的文件。下面將具體說明這個操作步驟:1. 打開Axf_To_Bin 文件中的Axf_To_Bin.uv2 工程文件;2. 打開Options for Target ‘Axf_To_Bin’對話框,選擇User 標簽頁;3. 構選Run User Programs After Build/Rebuild 框中的Run #1 多選框,在后邊的文本框中輸入C:\Keil\ARM\BIN31\fromelf.exe --bin -o ./output/Axf_To_Bin.bin ./output/Axf_To_Bin.axf 命令行;4. 重新編譯文件,在./output/文件夾下生成了Axf_To_Bin.bin 文件。在上面的步驟中,有幾點值得注意的是:1. C:\Keil\ARM\BIN31\表示RV MDK 的安裝目錄;2. fromelf.exe 命令的具體語法格式如下:命令的格式為:fromelf [options] input_file命令選項如下:--help 顯示幫助信息--vsn 顯示版本信息--output file 輸出文件(默認的輸出為文本格式)--nodebug 在生成的映象中不包含調試信息--nolinkview 在生成的映象中不包含段的信息二進制輸出格式:--bin 生成Plain Binary 格式的文件--m32 生成Motorola 32 位十六進制格式的文件--i32 生成Intel 32 位十六進制格式的文件--vhx 面向字節的位十六進制格式的文件t--base addr 設置m32,i32 格式文件的基地址--text 顯示文本信息文本信息的標志-v 打印詳細信息-a 打印數據地址(針對帶調試信息的映象)-d 打印數據段的內容-e 打印表達式表print exception tables-f 打印消除虛函數的信息-g 打印調試表print debug tables-r 打印重定位信息-s 打印字符表-t 打印字符串表-y 打印動態段的內容-z 打印代碼和數據大小的信息

  • 快速跳頻通信系統同步技術研究

    同步技術是跳頻通信系統的關鍵技術之一,尤其是在快速跳頻通信系統中,常規跳頻通信通過同步字頭攜帶相關碼的方法來實現同步,但對于快跳頻來說,由于是一跳或者多跳傳輸一個調制符號,難以攜帶相關碼。對此引入雙跳頻圖案方法,提出了一種適用于快速跳頻通信系統的同步方案。采用短碼攜帶同步信息,克服了快速跳頻難以攜帶相關碼的困難。分析了同步性能,仿真結果表明該方案同步時間短、虛警概率低、捕獲概率高,同步性能可靠。 Abstract:  Synchronization is one of the key techniques to frequency-hopping communication system, especially in the fast frequency hopping communication system. In conventional frequency hopping communication systems, synchronization can be achieved by synchronization-head which can be used to carry the synchronization information, but for the fast frequency hopping, Because modulation symbol is transmitted by per hop or multi-hop, it is difficult to carry the correlation code. For the limitation of fast frequency hopping in carrying correlation code, a fast frequency-hopping synchronization scheme with two hopping patterns is proposed. The synchronization information is carried by short code, which overcomes the difficulty of correlation code transmission in fast frequency-hopping. The performance of the scheme is analyzed, and simulation results show that the scheme has the advantages of shorter synchronization time, lower probability of false alarm, higher probability of capture and more reliable of synchronization.
