I wanted to verify that compatibility before I embed the chip in a bigger design so I built a breakout for the amplifier. Re: I2S syncronized MCLK output Post by ESP_Sprite » Mon May 01, 2017 6:44 am Both the I2S module as well as the timer module are fed from the main 80MHz APB clock, so they are actually synchronized in that respect. M5StickC内蔵I2Sマイクの録音データは、符号付き16ビットですので、2バイト単位で送信されてきます。精度は12ビットのようですが、実際のデータは16ビットなので、精度を意識しなくてもよいと思います。. Please add an output for the MCLK (oscillator) as well because most of the audio DAC's require it as a system clock anyway though it's not part of I2S specification (the ones which don't need MCLK are for an example the older TDA1543, TDA1387T and TDA1541A DACs, and from the more recent ones the PCM51xx which containins a PLL). 其中,Board (主控类)主要以ESP32、Bluno 等高性能、低功耗、具备无线传输功能的MCU 为核心 控制芯片,Covers 包括LED 点阵、I2S 音频驱动、GPS/GPRS/SIM 等为主板提供丰富外设,Accessories 包 括2.
