- 《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

- 74HC595[1] 是硅结构的CMOS器件， 兼容低电压TTL电路，遵守JEDEC标准。 74HC595是具有8位移位寄存器和一个存储器，三态输出功能。 移位寄存器和存储器是分别的时钟。 数据在SHcp（移位寄存器时钟输入）的上升沿输入到移位寄存器中，在STcp（存储器时钟输入）的上升沿输入到存储寄存器中去。如果两个时钟连在一起，则移位寄存器总是比存储寄存器早一个脉冲。 移位寄存器有一个串行移位输入（Ds），和一个串行输出（Q7’）,和一个异步的低电平复位，存储寄存器有一个并行8位的，具备三态
