Instructions:
Computer-based application method: You need to purchase a USB to TTL debugging tool, connect it to the speech synthesis module and insert it into the computer, open the supporting software, enter the corresponding text and select the port, and click Synthesize to play the sound of the corresponding text.
Application method between MCU: MCU needs to have a serial port, use the matching program to modify and transplant the program corresponding to the MCU, the communication format is: "5 bytes frame header + text", that is, send the corresponding text through the serial port of the MCU The content and text correspond to the calculated frame header. . . The frame header is about the length of the text, decoding format and other information.
1. This module has a standard 3.5mm standard audio interface, which can be plugged in audio and power amplifier equipment. The reserved speaker interface can directly drive 8 ohm 0.5W speakers.
2. The module input voltage can choose any power input of 3-5V, and the serial communication operation is simple. The baud rate can choose 3 communication levels, including: 9600, 19200, 38400bit/s.
3. Input the Chinese characters to synthesize the corresponding audio, output the sound through the audio output interface, use real human pronunciation, add background music function, multiple system sounds, just send the relevant instruction format to complete.
