单片机完成信号发生器的功能，由任意一个I/O口输出方波。PC机屏幕上显示“please input”频率值，通过RS232显示在PC机上，频率范围：0-500HZ。通过指令“setXXXHz”设置频率值。
时间显示在PC机上格式为“分：秒：百毫秒”，当输出指定方波10秒时间后，停止输出直到设置新的频率值。-MCU to complete the function of the signal generator, by any one of the I/O port output pulse. PC screen please input frequency values, through RS232 displayed on PC, frequency range: 0-500 hz. Through the instruction setXXXHz setting frequency value.
Time displayed on PC format for minutes: seconds: hundreds of milliseconds, whenever a given square wave output after 10 seconds, stop output until set a new frequency values.
