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从1992年开始为人们熟悉，到现在已经发展为μC/OS-II。ΜC/OS-II最多支持56个任务，其内核为占先式，总是执行就绪态的优先级最高的任务，并支持Semaphore（信号量）、Mailbox（邮箱）、Message Queue(消息队列)等多种常用的进程间通信机制。与大多商用RTOS不同的是，μC/OS-II公开所有的源代码，并可以免费获得，对商业应用收取少量License费用。

lpd6803是深圳英盛美半导体公司出品的一款高性能led驱动芯片，该芯片具有如下特点： 三路输出，恒流驱动：每路各有一个外挂电阻调整电流：Iout(max)=30mA, Vout(max)=12V。 兼容恒压模式，可直接替换ZQL9712等常规芯片。 直接PWM输出，无亮度损失，降低数据传输量，有效减少电磁干扰(EMI)。 支持32级灰度/256级灰度（内置反伽码校正逻辑）两种模式，扫描频率高（>4000HZ）。 仅需时钟线/数据线的两线传输结构，级联能力超强。 内建振荡器，支持FREE-RUN模式，降低控制电路成本。 内置LDO稳压电路，电源适应范围宽(4.8-8V)，输出耐压高（LED灯供电电压可达12V）。 简化外围配套，可扩充性好，也可作为PWM发生器控制大电流器件驱动大功率LED灯。 该芯片特别适合用于led幕墙灯、led全彩点光源、广告字、异型屏等产品，相对于9712/6106/595/5026/62726等芯片来说，外围器件少，电路简单， 布线容易，使用电线节省，控制器也简单。

uClinux上的应用程序设计 Luojia, Tsinghua Motorola MCU & DSP Center uClinux以其优异的性能、免费开放的代码等优点，博得众多嵌入式开发者的青睐。和过去基于简单RTOS甚至没有使用任何操作系统的嵌入式程序设计相比，基于Linux这样的成熟的、高效的、健壮的、可靠的、模块化的、易于配置的操作系统来开发自己的应用程序，无疑能进一步提高效率，并具有很好的可移植性。 在前面的章节中，我们已介绍了硬件平台、内核编译、开发环境等内容。如果仅仅有Hardware和OS，这个系统所能做的事情还非常有限。对于一个实际的嵌入式产品而言，所提供的功能和应用是关系到产品成败的重要因素。

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. By Daniel Perez Palomar (last revision: May 10, 2004). Feel free to distribute this file as it is (without including any modifications).

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
