Description

1. Description:

The 588D voice module uses the voice chip WT588D-20SS. It is with a 32Mbit capacity memory chip (Note: 1byte=8bit), it can store about 1000s voice. It carries the WT55U02-20SS download chip, and can download audio data directly to the memory chip through the host computer at the 588D computer without external downloader.

2. Features:

1>. Support loading 6K~20KHz sampling rate, WAV format audio.2>. Two types of output are supported by DAC/PWM. PWM output can directly drive 0.5W/8 Ohm horn, the push pull current is plentiful.3>. Support button control mode, first line serial port control mode, three line serial port control mode.4>. A variety of IO port triggers can be set under the button mode.

5>. The 220 segment can control the address bit, and a single address is loaded with a maximum of 128 segments of speech.6>. It will enter to the dormancy mode after the voice play to save power (Note: the mode of the first line serial port can not dormant).7>. With auxiliary upper computer software, which is easy to operate, arbitrary combination of voice8>. With internal unique voice processor, the sound is more natural and melodious.9>. The module leads to 9 pins, which is easy to use and simple.10>. Working voltage: DC3.3~5.5V.11>. Dormant current: less than 10uA.

3. Module test:

The module's factory default is all downloaded speech. According to the module connection schematic diagram, the button mode -PWM output circuit is connected to carry out function test (horn parameter 0.5W/8 ohm horn).1>. Speech output test: P0 short connect to ground and trigger voice. The speaker normal output voice means the module can be used normally2>. Voice download test: the USB-Micro data line (Android mobile data line) is connected to the module, and the computer will be automatically installed the driver. Start the software, load engineering files, click download.
