Library for Serial MP3 Player based on YX5300 IC (Catalex Module)
This library implements functions to control RS232 Serial MP3 players based
on the YX5300 and YX6300 ICs. These are often sold as “Catalex” Serial MP3 players.
The YX5300/YX6300 supports 8k Hz ~ 48k Hz sampling frequency MP3 and WAV file formats. The audio files
are stored on micro SD cards that plug into a TF card socket on the back of the board. The MCU
controls the MP3 playback by sending serial commands to the module via UART port. This library
manages the serial interface and request/response sequences.
