The 24-bit DAC output uses DSP hardware decoding, non-PWM output, dynamic range support 90dB, and signal ratio 85dB 5. Multiple control modes, two-wire serial port mode, and one-wire serial port control 6, support the previous song, the next song, play, pause, stop, song selection, and other common function controls 7. Support to obtain the serial number of the playing track, the total track and the total track list and other information 8. Support various information inquiries and easily obtain the current state of the voice chip 9. Support the insertion of the specified track, that is, you can pause the currently playing music, play the inserted track, and return to the original track breakpoint after playing 10. Support Chinese and English path insertion, in addition to the specified track insertion, also support the specified path insertion, only need to send the insertion path can be easily achieved 11. Support to specify Chinese and English path playback, without knowing the serial number of the content to be played, just send the path. 12. Support intelligent combination playback, the combination of songs in a specific folder can be combined by sending the track name. 13. Support 30-level volume adjustment 14. Support 5 kinds of EQ adjustment 15. Support 7 kinds of playback mode control, can adapt to different applications 16. Support cycle-by-time setting, more applications, more user-friendly 17. Support system deep sleep, the current is as low as 600 microamperes after sleep, and can be woken up by a string and command IO 18. Support fast forward and backward at specified time 19. Support repeating in specified time period 20. Support to start playing from the specified time 21. Special BUSY signal output indicator 22. Mature instructions and instruction analysis to make the application more stable
