There's no fullduplex I2S in STM32. The SPI/I2S unit is simplex in I2S mode, i.e. there's only one I2Sx_SD data pin (see the pin AF matrix in DS). You chose whether it's an input or output by setting the I2S to Rx or Tx in SPI_I2SCFGR.I2SCFG; that governs the data pi...
Digilent Pmod I2S2 参考手册说明书 Pmod I2S2 Reference Manual The Digilent Pmod I2S2 (Revision A) features a Cirrus CS5343 Multi﹊t Audio A/D Converter and a Cirrus CS4344 Stereo D/A Converter, each connected to one of two audio jacks. These circuits allow a system board to transmit ...

To avoid nuisance faults due to the DC detect circuit, hold the \SD pin low at power-up until the signals at the inputs are stable. HT566 I2S Input Stereo Class D Amplifier 过温保护在芯片内部结温达到 150℃时发 生,以防止芯片损坏,此时芯片进入关断状态, \FAULT 脚拉低.经过 tFAULT 时间后...
