03-【HAL库】STM32实现SYN6288模块语音播报.md

一、什么是SYN6288模块

1、概述

​ SYN6288 中文语音合成芯片是北京宇音天下科技有限公司于2010 年初推出的一款性/价比更高，效果更自然的一款中高端语音合成芯片。SYN6288 通过异步串口（UART）通讯方式，接收待合成的文本数据，实现文本到语音（或TTS 语音）的转换。
​ 宇音天下于2002 年最早研制出国内首款语音合成芯片 OSYNO6188。公司最新推出的 SYN6288 语音合成芯片，继承了 OSYNO6188 语音芯片的优秀特点：最小 SSOP28L 贴片封装、硬件接口简单、低功耗、音色清亮圆润、极高的性/价比；除此之外，SYN6288 在识别文本/数字/字符串更智能、更准确，语音合成自然度更好、可懂度更高。

2、芯片引脚图

二、使用方法

1、直接使用串口

硬件连接方式如下：

SYN6288引脚：

RX --> PA2

TX --> PA3

VCC --> 5V

GND --> GND

2、软件设置如下：

请注意：本次实验，我是用的是串口2，并且波特率选择为9600

3、实物连接图

2、关键函数

syn6288.c文件如下：

#include "syn6288.h"
#include "usart.h"
#include "string.h"
 
//Music:选择背景音乐。0:无背景音乐，1~15：选择背景音乐
void SYN_FrameInfo(uint8_t Music, uint8_t *HZdata)
{
  /****************需要发送的文本**********************************/
  unsigned  char  Frame_Info[50];
  unsigned  char  HZ_Length;
  unsigned  char  ecc  = 0;  			//定义校验字节
  unsigned  int i = 0;
  HZ_Length = strlen((char*)HZdata); 			//需要发送文本的长度
 
  /*****************帧固定配置信息**************************************/
  Frame_Info[0] = 0xFD ; 			//构造帧头FD
  Frame_Info[1] = 0x00 ; 			//构造数据区长度的高字节
  Frame_Info[2] = HZ_Length + 3; 		//构造数据区长度的低字节
  Frame_Info[3] = 0x01 ; 			//构造命令字：合成播放命令
  Frame_Info[4] = 0x01 | Music << 4 ; //构造命令参数：背景音乐设定
 
  /*******************校验码计算***************************************/
  for(i = 0; i < 5; i++)   				//依次发送构造好的5个帧头字节
  {
    ecc = ecc ^ (Frame_Info[i]);		//对发送的字节进行异或校验
  }
 
  for(i = 0; i < HZ_Length; i++)   		//依次发送待合成的文本数据
  {
    ecc = ecc ^ (HZdata[i]); 				//对发送的字节进行异或校验
  }
  /*******************发送帧信息***************************************/
  memcpy(&Frame_Info[5], HZdata, HZ_Length);
  Frame_Info[5 + HZ_Length] = ecc;
  HAL_UART_Transmit(&huart2,Frame_Info,5 + HZ_Length + 1,10000);
}
 
 
/***********************************************************
* 名    称： YS_SYN_Set(u8 *Info_data)
* 功    能： 主函数	程序入口
* 入口参数： *Info_data:固定的配置信息变量
* 出口参数：
* 说    明：本函数用于配置，停止合成、暂停合成等设置 ，默认波特率9600bps。
* 调用方法：通过调用已经定义的相关数组进行配置。
**********************************************************/
void YS_SYN_Set(uint8_t *Info_data)
{
  uint8_t Com_Len;
  Com_Len = strlen((char*)Info_data);
  HAL_UART_Transmit(&huart2,Info_data,Com_Len,10000);
}

syn6288.h如下

#ifndef __SYN6288_H
#define __SYN6288_H
 
#include "stm32f1xx_hal.h"
void SYN_FrameInfo(uint8_t Music, uint8_t *HZdata);
void YS_SYN_Set(uint8_t *Info_data);
 
#endif

main.c如下：

请注意：在main.c中，有以下代码需要重点关注：

[vx]：前景文本播放音量，x音量值，取值：0~16（其中0为静音）

[mx]：背景音乐音量，x为音量值，取值：0~16（其中0为静音）

[tx]：词语语速，x为词语语速值，取值：0~5（5为最高语速）
