Music Data From SPI Instead of SD Card

[hamzatamer76]

Hello,

in ADF there is example for playing music from sd card. But I want to play music from spi peripheral. ESP32 will be slave microcontroller STM32 will be Master. STM32 will transmit mp3 data via SPI. So;
This is for sd card example
[sdcard]-->fatfs_stream-->mp3_decoder-->resample-->i2s_stream-->[codec_chip]

I want to do this
[STM32]-->spi_reader-->mp3_decoder-->i2s_stream-->[codec_chip]
Is there helpful example in ADF or IDF for my project. How can i do this.
Thank you

Here is the official SPI SLAVE sample.

However, I don't know if it can communicate correctly with the STM32 SPI Master.
