Description: 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。

Description: Rijndael加密算法是分组长度可变的分组密码。分组长度，密钥长度可以为128，192，256比特。
假设加密的中间结果为状态State。状态State可以用类似于元素为一字节的矩阵来表示，矩阵的行数为4，列数为Nb，Nb等于分组长度除以32。
-Rijndael encryption algorithm is the grouping variable length block cipher. Packet length, key length for the bit 128,192,256. The assumption that an encrypted intermediate results for the state of State. State status is similar to the elements can be used as a matrix of bytes expressed as the number of rows for the matrix 4, the number of rows for the Nb, Nb equal to packet length divided by 32.
