说明：  《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.)
