Instructions:
- When you use the "Sound / download" function,it must not be inserted U disk on the board; connect the computer and Audio Interface though data lines ,audio can be output through the decoder board (using the player software to play music), also TF card can be read and written, but this mode can not play music storaged in U disk and TF card.
- Use recording mode; press the REC button on the remote control, the frequency of decoder indicator LED becomes faster , and start recording, press the REC button when recording is finished, the frequency of LED indicator becomes slower, and start playing the recording, after playing the recording ,it will switch to play music mode saved in TF card, if there is no TF card, it would switch to U disk play mode. (Audio (MP3 format) storaged in the TF card default, without TF card, storaged in the U disk).
- If using U disk play mode, it is recommended to use USB 5V power supply (not recommended for use 3.7V lithium battery-powered) since the early U disk does not support 3.7V voltage.
- POWER interface must be used when using a mobile power supply; Audio interfaces must not be used, or can not play the music storaged in U disk.
- Keyboard can be replaced through the microcontroller I / O port to achieve the music controls.
