红外的发射和接收 单片机红外发射（原理与设计程序）

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
