Description:
WTV**0SD**0S is one kind of core processing chip. It supports MP3
control mode, key control models (*-voice and *-voice), loop play
mode and two-line serial control mode. Control mode is set while
producing, which can not be changed through configuring.
1): MP3 control mode: Play / stop, next, last, volume +, volume -
and so on.
2): Key control mode (3 voice): One key to trigger a voice, can
play 3 pieces of voice and adjust volume. All keys are default as
no duplicate trigger for pulses.
3): Key control mode (5 voice): Three sub-control methods, 1. Key
can not be duplicate-triggered by pulse; 2. All keys are play /
stop trigger (No single recycled); 3. All keys are Play/Stop
(single can be recycled).
4): Loop play mode: After powered on, no need to trigger any I / O
port, directly play all the voice in SD card, with functions to
record playing points while power off, from which it plays while
powered on again. Two sub-control modes, 1. P*4 has pulse-triggered
play/pause function; 2. P*5 has level-triggered play/pause
function.
5): Two-line serial control mode: Controlled by MCU clock via CLK
and DI data lines. Free to play voice at any address. In this mode,
it has voice combination play function.
Audio content updates directly to SD card on the PC. The module
supports FAT file system. Support AD4 of 6kHz ~ *2kHz, *6kHz
sampling rate and WAV audio of 6kHz ~ *6kHz sampling rate.
Please notice that we can only supply two line serial control mode
by default now, thanks very much.
