Function Documentation

Microphone_Init()

void Microphone_Init

(

)

Initializes the microphone over I2S.

Note

The microphone cannot be enabled at the same time as the speaker since they both share a common pin (GPIO0). Attempting to enable and use both at the same time will cause the device to hard fault.

Microphone_Deinit()

void Microphone_Deinit

(

)

De-initializes the microphone over I2S.
