MW6 QRCode ASP.NET web control is 100％ consistent with the QRCode specification and extremely easy to use, the package downloadable from our website comes with an ASP.NET sample project which demonstrates exactly how to create the QRCode barcode in the ASP.NET environment.
為了在工業(yè)生產(chǎn)及過程控制中準(zhǔn)確測量溫度，設(shè)計了一種基于低功耗MSP430單片機的數(shù)字溫度計。整個系統(tǒng)通過單片機MSP430F1121A控制DS18B20讀取溫度，采用數(shù)碼管顯示，溫度傳感器DS18B20與單片機之間通過串口進行數(shù)據(jù)傳輸。MSP430系列單片機具有超低功耗，且外圍的整合性高，DS18B20只需一個端口即可實現(xiàn)數(shù)據(jù)通信，連接方便。通過多次實驗證明，該系統(tǒng)的測試結(jié)果與實際環(huán)境溫度一致，除了具有接口電路簡單、測量精度高、誤差小、可靠性高等特點外，其低成本、低功耗的特點使其擁有更廣闊的應(yīng)用前景。
Abstract:
In order to obtain accurate measuring temperature in industrial production and process control， a digital thermometer based on MSP430 MCU is designed. The system uses MSP430F1121A MCU to control DS18B20， and gets the temperature data， which is displayed on the LED. The temperature sensor DS18B20 and MCU transmit data through serial communication. MSP430 series has ultra-low power and high integration， DS18B20 only needs one port to achieve data communication. Through many experimental results prove， this system is consistent with actual environment temperature. The system has characteristics of interface circuit simple， high measuring accuracy， minor error， high reliability， besides， the characteristics of low cost and low power make it having vaster application prospect.
面向Eclips的Nios II軟件構(gòu)建工具手冊
The Nios® II Software Build Tools (SBT) for Eclipse™ is a set of plugins based on the
Eclipse™ framework and the Eclipse C/C++ development toolkit (CDT) plugins. The
Nios II SBT for Eclipse provides a consistent development platform that works for all
Nios II embedded processor systems. You can accomplish all Nios II software
development tasks within Eclipse, including creating, editing, building, running,
debugging, and profiling programs.
PID calculations for the _pid structure *a. This function uses the positional form of the pid equation, and incorporates an integral windup prevention algorithim. Rectangular integration is used, so this function must be repeated on a consistent time basis for accurate control.
THE SYNTAX OF A PROGRAMMING LANGUAGE tells you what code it is possible
to write—what the machine will understand. Style tells you what you ought to write—
what the humans reading the code will understand. Code written with a consistent, simple
style will be maintainable, robust, and contain fewer bugs. Code written with no regard to
style will contain more bugs. It may simply be thrown away and rewritten rather than
maintained.
usb 1.1 規(guī)范
The 1.1 revision of the specification is intended for product design. Every attempt has been made to ensure a
consistent and implementable specification. Implementations should ensure compliance with this revision.
