對于瀝青混凝土攤鋪機自動找平控制系統來說,數字式控制系統的研制是目前的一個方向。介紹了一種基于CAN總線的數字式自動找平控制系統。該系統以CAN總線作為通信方式,PWM控制信號通過C8051F040單片機內部PCA可編程計數器陣列產生,并具有結構簡單、信號穩定、實時性強、易擴展的特點。通過硬件實現和系統運行達到了比較理想的控制效果,驗證了系統的可行性。
Abstract:
A digital auto-leveling control system based on CAN Bus is introduced.It uses CAN Bus as the method of communication and Creates PWM signals by programmable counter array in C8051F040 microcontroller. The system is simple, stable, real-time and expansive.

The LogiCORE™ GTP Wizard automates the task of creating HDL wrappers to configure the high-speed serial GTP transceivers in Virtex™-5 LXT and SXT devices. The menu-driven interface allows one or more GTP transceivers to be configured using pre-definedtemplates for popular industry standards, or from scratch, to support a wide variety of custom protocols.The Wizard produces a wrapper, an example design, and a testbench for rapid integration and verification of the serial interface with your custom function
Features• Creates customized HDL wrappers to configureVirtex-5 RocketIO™ GTP transceivers• Users can configure Virtex-5 GTP transceivers toconform to industry standard protocols usingpredefined templates, or tailor the templates forcustom protocols• Included protocol templates provide support for thefollowing specifications: Aurora, CPRI, FibreChannel 1x, Gigabit Ethernet, HD-SDI, OBSAI,OC3, OC12, OC48, PCI Express® (PCIe®), SATA,SATA II, and XAUI• Automatically configures analog settings• Each custom wrapper includes example design, testbench; and both implementation and simulation scripts

使用Nios II軟件構建工具
This chapter describes the Nios® II Software Build Tools (SBT), a set of utilities and
scripts that Creates and builds embedded C/C++ application projects, user library
projects, and board support packages (BSPs). The Nios II SBT supports a repeatable,
scriptable, and archivable process for creating your software product.
You can invoke the Nios II SBT through either of the following user interfaces:
■ The Eclipse™ GUI
■ The Nios II Command Shell
The purpose of this chapter is to make you familiar with the internal functionality of
the Nios II SBT, independent of the user interface employed.

This example program shows how to configure and use the A/D Converter of the following microcontroller:
STMicroelectronics ST10F166
After configuring the A/D, the program reads the A/D result and outputs the converted value using the serial port.
To run this program...
Build the project (Project Menu, Build Target)
Start the debugger (Debug Menu, Start/Stop Debug Session)
View the Serial Window (View Menu, Serial Window #1)
View the A/D converter peripheral (Peripheral Menu, A/D Converter)
Run the program (Debug Menu, Go)
A debug script (debug.ini) Creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change.
Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals graphically.

unix或linux下的DNA分析軟件源碼
其功能如下
1. Edit up to 256 peptide or DNA sequences simultaneously.
2. Translates DNA->protein click next to display next frame.
3. Dot matrix plot of any 2 sequences.
4. Rudimentary amino acid statistics (MW and amino acid percentage)
5. Saves matrix plot as PBM image format.
6. Sequence reversal.
7. Creates alignment file for highlight (below).
8. Tab key toggles editing of next sequence.

驅動開發向導
I came across an article QuickSYS which implements an NT driver framework. That article demonstrates a MFC application that gets a project name as a parameter and Creates Visual C++ workspace with NT driver framework. I decided to copy the NT driver framework source and to put it in the Visual Studio project wizard as seen above. This is simpler rather than running an external executable application that generates the code for you.

Student status management system is development two aspects that typical information management system, IMS( MIS), its development includes primarily the background database Creates with support and the front end applies the procedure.Creates to rise to the former request the consistency of data is strong with the integrity, the library that the safeness of data like.But request the latter very much to apply the procedure function complete, easy usage etc. characteristics.
