Description of each block’s movement-part3
11. KEY matrix controller
· Controls 12 types of KEY inputs: play/pause, stop, tune forward/fast forward playing, tune backward/fast backward
playing, folder forward, folder backward, 10-tune forward, volume up, volume down, repeat play, random play and
device selection.
12. LED controller
· Controls 7 types of LED outputs: play/pause, error, memory accessing, random playing, repeat playing, USB
selection and SD selection
13. Control from the master microcomputer
· Control from the master microcomputer is enabled using the I2C interface.
· Through the command operations, the following can be controlled: play, pause, stop, tune forward, tune backward,
fast forward playing, fast backward playing, folder forward, folder backward, 10-tune forward, 10-tune backward,
volume up, volume down, device selection, volume setting, repeat selection, random play, digital audio output setting,
sound effect setting, resume data setting and direct tune selection data setting.
· Controls the following: playing status output, pause, stop, searching, error, folder number, file number within folder,
play time information, number of total folders, number of total files, name of folder being played, name of file being
played, ID3TAG (title, artist and album) , WMATAG (title, artist and album), AACTAG (title, artist and album),resume
data and direct tune selection data (MODE3).
14. Function selection
· Selects MODE1 or MODE2/3 (SEL_SLAVE=H: MODE1, L: MODE2/3).
· Selects MPEG Audio Layer (SEL_MP3=H: play MP3 only, L: play MP1/MP2/MP3)
· Digital audio output selection (SEL_DOUT=H: output OFF, L: output ON)
· Sound volume operation selection (SEL_VOL=H: volume adjustable, L: volume not adjustable MAX output)
· Selects operation at power ON to check device (SEL_APLAY=H: stop, L: play). *Enabled in MODE 1 only.
· Selects MODE2 or MODE3 (SEL_SMAN=H: MODE2, L: MODE3). *Enabled in MODE 2/3 only.
15. File Read function in USB memory
· The specified data of file that exists in the root folder of the USB memory reading is possible.
* The file name corresponds only by 8.3 forms. (The wild-card cannot be used.)
