Reading from SD card - Arduino IDE example

[trackme518]

Hi,
I wanted to play files from SD card and use Arduino IDE to program it. After some digging I was able to use SdFat V2 from https://github.com/greiman/SdFat and found a bug in Audio.cpp from ESP32-audioI2S lib. I have tested it's working playing mp3 files (can't read wav yet thought). I am attaching the example for Arduino IDE.

Instructions:

• install SdFat V2 from https://github.com/greiman/SdFat
• activate "SDFATFS_USED" in Audio.h
• activate "#define USE_UTF8_LONG_NAMES 1" in SdFatConfig.h
• you need to fix bug in Audio.cpp, line 2870 from ESP32-audioI2S lib, replace:
• availableBytes = min(availableBytes, audiofile.size() - byteCounter);
• with:
• availableBytes = min(availableBytes, (uint32_t)audiofile.size() - byteCounter);
