采用STC89C51编写的125K射频卡阅读器程序，采用EM4096基站芯片。(125K RF using STC89C51 written card reader program, the the EM4096 base station chip.)

说明：  实现避障的基础功能，使用stm32f103rct6板子(this is very good idea!)

使用stm32f103c8t6 输出pwm，可实现正弦波，三角波，锯齿波。(use stm32f103c8t6 to make pwm.)

利用单片机定时器产生高低电位各0.5毫秒的方波，该方波再经二阶滤波变成1K赫兹的正弦波，即为音频信号(To produce high and low potential of each 0.5 ms using SCM timer Fang Bo, the square wave and then by two order filter into 1K Hz sine wave, namely for audio signal )
