Need to add sound to your project? Voice prompts? Sound effects in games? Robots that bleep or boop or scream? Talking alarm systems?
The WT588D, a so-called ‘voice chip’, allows you to add custom sound clips in the form of WAV files to your project.
WT588D is a powerful re-programming voice chip microcontroller. Its control mode can be changed and download data to SPI flash by our PC software. This software is easy-operating ,support online download ,even the chip in power on , data can be download to the related SPI flash then reset the circuit, the control mode will be updated. In the Mp3 control mode, this chip with mp3 player functions , such as play, pause, previous, next, volume up, volume down.
In the key control mode, the trigger mode is flexible, any key can be setted as edge retrigger, edge no retrigger, level unloop, level loop,, level hold loop, prev unloop, next unloop, prev loop, next loop, no function, pause, stop, vol+, vol- and on/off 15 kinds of trigger mode, control 10 key trigger output max.
In the 3x8 key combination control mode,24 addresses’ voice can be triggered by edge retrigger mode.
In the parallel control mode, 8 I/O port can be used in controlling max
In the one-line serial control mode, voice play, stop, re-play, volume adjustment can be controlled by MCU.
Three-line serial control mode and three-line serial control I/O port extension mode can be switched , in
the three-line control mode, voice play, stop, re-play and volume adjustment can be controlled , or direct trigger
voice in 0-219 addresses. In the three-line serial control I/O port extension mode, can extend 8 bit output.
Switch between these two control mode, last working status still keep going in current mode.
PWM output can direct drive 0.5W/8Ω speaker, DAC output connect to external amplifier.
WT588D with a wide range of applications, such as bus reporter, alarm, reminder, alarm clock, study apparatus,
household appliances, medical instrument, electronic toys, telecommunication, parking distance control and so on.
