PC 通过串口工具在发送节点A 端输入想要发送的数据，点击发送，在接收节点B 端 PC 上的串口工具上，可以看到节点B 收到的内容。如要发送10 个字节内容为11 22 33 44 55 66 77 88 99 AA 的数据/时，在发送节点A 端的串口工具上输入 0A 11 22 33 44 55 66 77 88 99AA，其中0A 代表要发送数据的长度，以16 进制表示。在接收节点B 端的串口工具上就可以收到相应的数据。-PC through the serial port tool sending node A wants to send data from client input, click on send, at the receiving node B-side on a PC serial port tools, you can see the node B received. If you want to send 10 bytes of content 11 22 33 44 55 66 77 88 99 AA of the data/pm at the sending node A on the input side of serial port tools 0A 11 22 33 44 55 66 77 88 99AA, in which you want to send on behalf 0A the data length to 16 hexadecimal said. Node B at the receiving end of the tool on the serial port can receive the corresponding data.

void InitGoertzel(void) 作用：初始化算法参数 用法：采用算法进行检测前执行一次，如果需要改变参数，调用SetParameter() float CGoertzel::GetMagnitude(unsigned char * sampleData, int length) //算法主接口 作用：对采集下来的音频数据用算法处理，返回一个结果 参数：sampleData－音频数据缓冲地址指针； length-缓冲区尺寸(音频数据数量),字节数； 返回值：返回算法结果。 void SetParameter(DWORD set_SampleRate, DWORD set_TargetFreq, DWORD set_BlockSize) 作用：设置算法参数； 参数：set_SampleRate-音频数据抽样速率； set_TargetFreq-目标信号频率； set_BlockSize－算法数据块尺寸(采样点)； 用法：调用本函数后，需要调用一次InitGoertzel(void)才会生效-void InitGoertzel (void) function: initialization algorithm parameters Usage: The algorithm performs a pre-test, if the need to change the parameters, calling SetParameter () float CGoertzel:: GetMagnitude (unsigned char* sampleData, int length)// Algorithm for the main interface role: to collect audio data from the treatment algorithm to return a result parameter: sampleData-audio data buffer address pointer length-buffer size (the number of audio data), number of bytes return value: the return of
