stm32语音播报_TTS语音模块：XFS5152CE语音合成模块详解代码

XFS5152CE是一款TTS语音模块，可以通过串口与STM32等微控制器连接，实现文字转语音的功能。以下是一个简单的STM32语音播报代码，可以作为参考：

#include "stm32f10x.h"
#include <string.h>

#define USARTx                   USART1
#define USARTx_IRQn              USART1_IRQn
#define USARTx_IRQHandler        USART1_IRQHandler

#define XFS5152CE_BAUDRATE       9600

void USART_Config(void)
{
    USART_InitTypeDef USART_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);

    // USART1_TX
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // USART1_RX
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    USART_InitStructure.USART_BaudRate = XFS5152CE_BAUDRATE;
    USART_InitStructure.USART_WordLength = USART_WordLength_8b;
    USART_InitStructure.USART_StopBits = USART_StopBits_1;
    USART_InitStructure.USART_Parity = USART_Parity_No;
    USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
    USART_Init(USARTx, &USART_InitStructure);

    NVIC_InitStructure.NVIC_IRQChannel = USARTx_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    USART_ITConfig(USARTx, USART_IT_RXNE, ENABLE);

    USART_Cmd(USARTx, ENABLE);
}

void send_string(char *str)
{
    while (*str) {
        USART_SendData(USARTx, (uint8_t) *str++);
        while (USART_GetFlagStatus(USARTx, USART_FLAG_TXE) == RESET);
    }
}

void XFS5152CE_play(char *text)
{
    char cmd[50];
    strcpy(cmd, "SPEAK \"");

    strcat(cmd, text);
    strcat(cmd, "\"\r\n");

    send_string(cmd);
}

void XFS5152CE_init(void)
{
    send_string("\r\n\r\n"); // 重启模块
    send_string("AT+CLR\r\n"); // 清空缓存
    send_string("AT+V\r\n"); // 查询版本号
    send_string("AT+L=3\r\n"); // 设置语音播报速度
    send_string("AT+T=0\r\n"); // 设置语音播报音调
}

int main(void)
{
    USART_Config();
    XFS5152CE_init();
    XFS5152CE_play("Hello, world!");

    while (1);
}

void USARTx_IRQHandler(void)
{
    if (USART_GetITStatus(USARTx, USART_IT_RXNE) != RESET) {
        USART_ClearITPendingBit(USARTx, USART_IT_RXNE);
    }
}

该代码通过串口与XFS5152CE语音模块通信，实现了文字转语音的功能。在`XFS5152CE_init()`函数中，可以通过AT指令设置语音播报速度和音调。在`XFS5152CE_play()`函数中，将要播报的文本转换成特定格式的字符串，并通过串口发送给模块。
