Description: SM0038对外只有3个引脚：VS、GND和1个脉冲信号输出引脚OUT，外形引脚如图二所示。与单片机接口非常方便，如图三所示。VCC接电源+5V并经电容进行滤波，以避免电源干扰 GND接系统的地线（0V）；脉冲信号输出接CPU的中断输入引脚（例如8051的13脚INT1）。采取这种连接方法，软件解码既可工作于查询方式，也可工作于中断方式。-SM0038 external only three pins: VS, GND, and a pulse signal output pin OUT, pin shape as shown in Figure 2. With the MCU interface is very convenient, as shown in Figure 3. VCC Power Supply+5 V, and then is filtered by the capacitor in order to avoid interference with the power GND then the system ground (0V) pulse signal output next CPU interrupt input pins (such as 8051' s 13-pin INT1). Take this connection method, the software decoder can work on ways to search, but also works in interrupt mode.
