CANopen is a networking system based on the CAN serial bus. CANopen assumes that the device’s hardware has a CAN transceiver and CAN controller as specified in ISO 11898. CANopen profile family specifies standardized communication mechanisms and device functionality. The profile family is available and maintained by CAN in Automation (CiA), the international users’ and manufacturers’ group and may be implemented license-free.

Application Note Abstract This Application Note introduces a complete and detailed PSoC® project. Telephone Call Logger keeps the detailed record of approximately 945 phone calls (7-digit number is assumed to be one phone call) including date, start time and the duration of the phone call in the PSoC device. Users can get this detailed report into the PC environment by using free software, which is included in the project file. When records reach near full capacity of the Flash memory, an LED will turn on to show that it is necessary to backup the data. Software gets the data from PSoC, organizes it and prepares a printable version. Additionally, it sends the date and time information to the PSoC. The external parts in this project can be obtained easily in the market.

μC/OS從1992年開始為人們熟悉，到現(xiàn)在已經(jīng)發(fā)展為μC/OS-II。ΜC/OS-II最多支持56個任務(wù)，其內(nèi)核為占先式，總是執(zhí)行就緒態(tài)的優(yōu)先級最高的任務(wù)，并支持Semaphore（信號量）、Mailbox（郵箱）、Message Queue(消息隊列)等多種常用的進(jìn)程間通信機(jī)制。與大多商用RTOS不同的是，μC/OS-II公開所有的源代碼，并可以免費(fèi)獲得，對商業(yè)應(yīng)用收取少量License費(fèi)用。

lpd6803是深圳英盛美半導(dǎo)體公司出品的一款高性能led驅(qū)動芯片，該芯片具有如下特點(diǎn)： 三路輸出，恒流驅(qū)動：每路各有一個外掛電阻調(diào)整電流：Iout(max)=30mA, Vout(max)=12V。 兼容恒壓模式，可直接替換ZQL9712等常規(guī)芯片。 直接PWM輸出，無亮度損失，降低數(shù)據(jù)傳輸量，有效減少電磁干擾(EMI)。 支持32級灰度/256級灰度（內(nèi)置反伽碼校正邏輯）兩種模式，掃描頻率高（>4000HZ）。 僅需時鐘線/數(shù)據(jù)線的兩線傳輸結(jié)構(gòu)，級聯(lián)能力超強(qiáng)。 內(nèi)建振蕩器，支持FREE-RUN模式，降低控制電路成本。 內(nèi)置LDO穩(wěn)壓電路，電源適應(yīng)范圍寬(4.8-8V)，輸出耐壓高（LED燈供電電壓可達(dá)12V）。 簡化外圍配套，可擴(kuò)充性好，也可作為PWM發(fā)生器控制大電流器件驅(qū)動大功率LED燈。 該芯片特別適合用于led幕墻燈、led全彩點(diǎn)光源、廣告字、異型屏等產(chǎn)品，相對于9712/6106/595/5026/62726等芯片來說，外圍器件少，電路簡單， 布線容易，使用電線節(jié)省，控制器也簡單。

uClinux上的應(yīng)用程序設(shè)計 Luojia, Tsinghua Motorola MCU & DSP Center uClinux以其優(yōu)異的性能、免費(fèi)開放的代碼等優(yōu)點(diǎn)，博得眾多嵌入式開發(fā)者的青睞。和過去基于簡單RTOS甚至沒有使用任何操作系統(tǒng)的嵌入式程序設(shè)計相比，基于Linux這樣的成熟的、高效的、健壯的、可靠的、模塊化的、易于配置的操作系統(tǒng)來開發(fā)自己的應(yīng)用程序，無疑能進(jìn)一步提高效率，并具有很好的可移植性。 在前面的章節(jié)中，我們已介紹了硬件平臺、內(nèi)核編譯、開發(fā)環(huán)境等內(nèi)容。如果僅僅有Hardware和OS，這個系統(tǒng)所能做的事情還非常有限。對于一個實(shí)際的嵌入式產(chǎn)品而言，所提供的功能和應(yīng)用是關(guān)系到產(chǎn)品成敗的重要因素。

This function obtains a unitary matrix Q such that: d=diag(Q *diag(lmd)*Q). In other words, it gives a way to generate a matrix with given eigenvalues and diagonal elements.

These listed libraries are written in WTL. But it s really hard to mix both MFC & WTL together. Obviously, it s not reasonable to ask a developer or a team to giving up MFC and move to the WTL world just because there were some great controls or visual Frameworks written in WTL (there are many things that should be considered especially in a company with hundreds of developers like the company I work for). Unfortunately, there was no such good and free visual Framework in MFC until now. Whatever difficulties there are, I still desire to be able to use them and now my effort is here to be shared with you. Under the Hood
