|
|
* @brief SDFAT Audio Player example for ESP32-S3-AI-Smart-Speaker.
|
|
* Unfortunatly the SD cd pin is mapped to EXIO4 and not to a regular GPIO pin.
|
|
* This requires the custom functions SdCsInit and SdCsWrite. Make sure that
|
|
* SD_CHIP_SELECT_MODE is set to 1 in SdFatConfig.h.
|
|
*
|
|
* This makes sure that the SD is only active when it is actually used, so that
|
|
* we can extend the battery life!
|
|
*
|
|
* Please note that this examples also works w/o the custom functions since the
|
|
* AudioKit driver already configures the EXIO4 pin for SD use.
|
|
