MedeaWiz® Sprite® 4K
.
Further explanation of some serial commands
0xCB Request the total number of files on the SD card. The Sprite® will send a feedback byte
telling the total number of files on the SD card. The Sprite® feedback will be CB, CB, xx where xx
is the number of files in Hexadecimal.
0XCC Request the file number currently playing.
0xE0 to 0xEF Address numbers for the Sprite®. If the Sprite® is set to an Address E1 to EF in the
Setup Menu, then the Sprite® will only follow commands preceded by the correct address.
All players set to an address will also respond to the Broadcast Address E0.
The Host can transmit commands to many Sprites on the same serial line.
You should only use 1 Sprite® for feedback to the Host to avoid data collisions.
Note that some addresses are also used as commands. If the Sprite is set to Do not use Address,
you can use these commands normally. If Sprites are set to an address, you can still use these
commands following the Address byte. As example, with a Sprite set to address E9, you can still
use the Volume up command E9. Transmit 2 bytes: Address, Command as E9, E9.
It is not recommended to mix Sprites set to Do not use Address with those using an address on
the same serial line as unintended results may occur.
0xE8 Mute the audio. Mute only. Mute command does not toggle on / off.
0xE9 Increase volume one step for each command received. If the Sprite® was Mute, the first
0xE9 command will cancel Mute and return to the previous volume level.
0xEA Decrease volume one step for each command. If the Sprite® was Mute, the first 0xEA
command will cancel Mute and return to the previous volume level.
0xEF Play - Resume play after a Pause. Play command does not toggle Play / Pause.
A Play command will Cancel FF>>or FB<< in progress.
0xF0 Pause - Does not toggle Play / Pause. You must send 0xEF Play command to resume.
A Pause command will Cancel FF>> or FB<< in progress
0xF5 Returns the current position in the file playing as the number of milliseconds.
The return will be 0xF5 followed by 4 bytes representing the position. Low Byte is first.
0xF6 Seek to your specified position in the file and begin playing.
Example: Send 0xF6, xx, xx, xx, xx. It is not necessary to send zero-value high bytes.
0xF7 Returns the total length of the file in milliseconds.
