源端输出是原始的高采样率(oversample)调制数据,如Sigma-Delta调制器的输出,而不是像I2S中那样的抽取数据(An I2S output digital microphone includes the decimation filter, so its output is already at a standard audio sample rate that's easy to interface to and process.)。基于PDM接口的应用降低了发送...

读状态寄存器 0x75为0x00,说明芯片当前时钟No Error, 读状态寄存器 0x78为0x07,说明电压DVDD Status、AVDD Status、Digital LDO Status的电压都为Good. 但芯片数据输出引脚Pin 18 Audio data digital output 就是没有数据出来,用示波器量也没有波形。 也写过别的寄存器,还是不行。 请问我软件方面还有漏缺的吗?...
PCM audio(Pulse-Code Modulation) is one type of digital audio. Ananalog electrical signalfrom a microphone is converted to digital form. In AV-applications PCM is a data-uncompressed alternative to Dolby Digital technology. PCM is representation of an analog acoustic waveform as sequence of samples...
