How to Enable LINE IN Mode with ESP_VS1053_Library?

[yoshihir0]

Hi,

I’m using the ESP_VS1053_Library with an ESP32 to control a VS1053 chip. I would like to enable the LINE IN mode (using the SM_LINE1 bit in the SCI_MODE register) to process audio from an external source. However, I couldn’t find any specific examples or methods in the library documentation for this.

Could you please guide me on how to enable LINE IN mode using this library? If it’s not directly supported, is there a recommended way to modify the library or send the necessary commands to the VS1053?

Thank you for your help!
