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。

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

This package provides a complete http client library. It currently implements most of the relevant parts of the HTTP/1.0 and HTTP/1.1 protocols, including the request methods HEAD, GET, POST and PUT, and automatic handling of authorization, redirection requests, and cookies. Furthermore the included Codecs class contains coders and decoders for the base64, quoted-printable, URL-encoding, chunked and the multipart/form-data encodings. The whole thing is free, and licenced under the GNU Lesser General Public License (LGPL) (note that this is not the same as the GPL).

This folder has some scritps that you may find usefull. All of it comes from questions that I ve received in my email. If you have a new request/question, feel free to send it to marceloperlin@gmail.com. But please, don t ask me to do your homework. Passing_your_param0 This folder contains instructions (and m files) for passing you own initial parameters to the fitting function. I also included a simple simulation script that will create random initial coefficients (under the proper bounds) and fit the model to the data.
