Getting metadata tags to print to a display #743

|
Hi, I’m working on an sd card audio player with an LCD display. I am largely using your library and everything has gone smoothly so far, except I haven’t been able to figure out how to read ID3V2 tags using the metadata functionality of the library to print information about the songs to the display. Any help or pointing in the right direction would be great. :) |
