18c2ecf20Sopenharmony_ciInvensense ICS-43432 MEMS microphone with I2S output.
28c2ecf20Sopenharmony_ci
38c2ecf20Sopenharmony_ciThere are no software configuration options for this device, indeed, the only
48c2ecf20Sopenharmony_cihost connection is the I2S interface. Apart from requirements on clock
58c2ecf20Sopenharmony_cifrequency (460 kHz to 3.379 MHz according to the data sheet) there must be
68c2ecf20Sopenharmony_ci64 clock cycles in each stereo output frame; 24 of the 32 available bits
78c2ecf20Sopenharmony_cicontain audio data. A hardware pin determines if the device outputs data
88c2ecf20Sopenharmony_cion the left or right channel of the I2S frame.
