ecos RTOS 原理介绍和应用开发The design philosophy of eCos was to augment an open-source RTOS (which meant no per-unit royalties) with source-level con?guration tools that would enable embedded developers to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu- ally chAnge a line of source code.

This is a device for use by RC hobbysts: it transforms a servo from proportional to integrative. For RC boats, it allows user not to chAnge the functionality of the throttle stick, UP/DOWN in stead of proportional. The archive contains also the PCB files.

Traveling Salesperson Problem Our branch-and-strategy splits a branch and bound solution into two groups: one group including a particular arc and the other excluding this arc. 1.Each splitting incurs a lower bound and we shall traverse the searching tree with the "lower" lower bound. 2.If a constant subtracted from any row or any column of the cost matrix, an optimal solution does not chAnge.

alter table tbl_name add col_name type 例如,给表增加一列weight mysql>alter table pet add weight int 删除列 alter table tbl_name drop col_name 例如，删除列weight： mysql>alter table pet drop weight 改变列 alter table tbl_name modify col_name type 例如，改变weight的类型： mysql> alter table pet modify weight samllint 另一种方法是： alter table tbl_name chAnge old_col_name col_name type 例如： mysql> alter table pet chAnge weight weight samllint 给列更名 mysql>alter table pet chAnge weight wei 给表更名 alter table tbl_name rename new_tbl 例如，把pet表更名为animal mysql>alter table pet rename animal

1. Download the version you want: * Version 1.3.4 (30 Aug 2007) -- this is the latest version for UNIX/Linux and Windows * Previous versions 2. Unzip the file, which will create a directory called klt and place all the files there 3. Compile and run the code * On UNIX / Linux, move to the klt directory, type make. Now try some examples, by typing example1, etc. * For Microsoft Visual C++ 6.0, open the klt.dsw file, compile, and run. chAnge the constant in main.cpp to run the different examples. * For Microsoft Visual Studio .Net/7/8, open the klt.sln file, compile, and run. chAnge the constant in main.cpp to run the different examples. 4. Notice that, for your convenience, unofficial copies of the User and Reference Manuals can be found in the doc directory.

This code outputs various NMEA strings to a com port. The code was originally used to test naviation programmes. First select the required com port and the required NMEA message string. There is a default starting position but this can be chAnged to suit just by typing in a new position. Click on the Start button the current position displayed will chAnge according to the speed and heading selected and the selected NMEA string will be output to the com port and will reflect the current position as displayed. There is a text box which is normally not visible. If you chAnge this to visible the relevant NMEA string can be displayed.

High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must chAnge.

Besides enhanced looks and advanced features, one of the best things about Swing is its pluggable look and feel (PLAF). PLAF architecture allows seamless chAnges in the appearance of an application and the way an application interacts with the user. However, designing and developing a PLAF is much more exhaustive and complex. On the other hand, themes provide a simple alternative to chAnge look and feel of the swing application. Themes are easier to implement and they enhance the visual appeal of the application UI using the default Java look and feel. Theme mechanism allows a developer to easily specify the default colors, fonts and icons used by the look and feel (L&F). It allows developers to write their own themes giving them a choice to show their application GUI the way they want it, rather than depending on the defaults provided by the system.
