Description: 《角度测量器》
用光电编码器测量角度，每个脉冲为0.72度。
测量范围：0.0～360.0度
为保证不错过脉冲，用timer1计数，在电平跳变中断里判断转动方向，尽量加快处理过程。
数据换算和数码管扫描显示在主循环中实现。
译码器用10米长5芯屏蔽线与数显器的两片74HC595连接。
MCU为12F629，使用内部4兆RC振荡和内部复位功能。
-"angle measuring device" using photoelectric encoder measurement perspective, each pulse of 0.72 degrees. Measuring range : 0.0 to 360.0 degrees to ensure the well-off pulse, with timer1 count, in Level Trip interruption Lane judge the direction of rotation, to speed up the process. Data conversion and digital control display in the main scanning cycle to achieve. Decoding the Formosan 10-meter-long five core shield wire with a few significant for the two Bit link. MCU for the 12F629, the use of 4 megabytes of internal RC oscillation and internal reset function.

Description: 找了很久才找到的。现上传上来共享。
M74HC595 是一个八位串行输入，平行输出的位移缓存器；平行输出为三态输出。在SCK 的上升缘，串行数据由SDI输入到内部的八位位移缓存器，并由Q7’输出。
而平行输出，则是在LCK 的上升缘，将在八位位移缓存器的数据存入到八位平行输出缓存器。当OE 的控制讯号为低致能时， 平行输出端的输出值，等于平行输出缓存器所储存的质。而当OE 的控制讯号为高电位，也就是输出关闭时，平行输出端会维持在高阻抗状态。.
M74HC595 保持了和一般74HC595 功能上以及脚位上的兼容性之外，并针对一些特性予以强化。这些强化的特性，使得M74HC595 非常适合用于像是LED 数组指示器、LED 讯号显示矩阵等需要较大的灌电流应用。每个通道可接受的灌电流都被加大了，使得M74HC595 可以支持更大的LED 电流。而增大的接地电流，可支持数个平行输入通道的同时打开，并灌大电流。比起传统的74HC595，平行输出端同时有较大灌电流时，可靠度增强了四倍以上。
