TTS串口SYN6288语音合成模块的使用简介

最近在项目中使用TTS串口的SYN6288语音合成模块来输出中文语音，遇到一些问题，尤其是协议中的校验和计算的问题，折腾了好长时间。

使用的芯片如下图所示：

首先在电脑的串口上调试通过，串口的设置参数如下图所示：

上图中主要需要注意的就是 波特率，数据位，停止位，控制这几个地方。

对于使用Python脚本调试的情况，可以参考如下的代码：

import serial
import struct

PORT = "/dev/tty.SLAB_USBtoUART"

# configure the serial connections (the parameters differs on the device you are connecting to)
ser = serial.Serial(
    port=PORT,
    baudrate=9600,
    xonxoff=False,
    parity=serial.PARITY_NONE,
    stopbits=serial.STOPBITS_ONE,
    bytesize=serial.EIGHTBITS
)

print ser

ser.isOpen()

s=struct.pack("5B32sB", 253,0,35,1,0,'\xBB\xB6\xD3\xAD\xB9\xE2\xC1\xD9\xB0\xB2\xC8\xBB\xD6\xAE\xBC\xD2\xD6\xC7\xC4\xDC\xB5\xE7\xD7\xD3\xB9\xA4\xD7\xF7\xCA\xD2\x0D\x0A',241)

ser.write(bytearray(s))

#ser.write(b'\xFD\x00\x21\x01\x01\xBB\xB6\xD3\xAD\xB9\xE2\xC1\xD9\xB0\xB2\xC8\xBB\xD6\xAE\xBC\xD2\xD6\xC7\xC4\xDC\xB5\xE7\xD7\xD3\xB9\xA4\xD7\xF7\xCA\xD2\xF1')

print ser.read()

对于使用C开发的情况，参考如下的代码：

#define VOICE_UAER_BAND_RATE (9600u)

#define VOICE_CMD_PREFIX (0xFD)
#define VOICE_CMD_PLAY (0x01)
#define VOICE_BGM (0x01)

typedef struct __attribute__((__packed__)) _VOICE_CMD {
    uint8_t     cmd_prefix; /*fixed head*/
    uint16_t    len; /* message length*/
    uint8_t     ctrl_cmd; /* control command*/
    uint8_t     bgm; /*background music*/
    char        msg[0]; /*message content*/
    uint8_t     xor_checksum; /*checksum*/
}VOICE_CMD;

typedef struct _VOICE_CMD* PVOICE_CMD;

//const static char contentBuf[30] = {0xBB,0xB6,0xD3,0xAD,0xB9,0xE2,0xC1,0xD9,0xB0,0xB2,0xC8,0xBB,0xD6,0xAE,0xBC,0xD2,0xD6,0xC7,0xC4,0xDC,0xB5,0xE7,0xD7,0xD3,0xB9,0xA4,0xD7,0xF7,0xCA,0xD2};

#define sw16(x) \
    ((short)( \
        (((short)(x) & (short)0x00ffU) << 8 ) | \
        (((short)(x) & (short)0xff00U) >> 8 ) ))

static PVOICE_CMD genVoiceCmd(char* buffer,uint8_t len)
{
    PVOICE_CMD cmd = (PVOICE_CMD)VOICE_BUFFER;
    uint8_t i = 0;
    char* xor_buf = (char*)cmd;
    uint8_t xor = 0;
    char* xor_sum = (char*)(cmd->msg) + len;
    memset(xor_buf,0,sizeof(VOICE_CMD));

    cmd->cmd_prefix = VOICE_CMD_PREFIX;
    cmd->len = len + sizeof(VOICE_CMD) - sizeof(uint8_t) - sizeof(uint16_t); /*real_length - prefix - length*/
    cmd->len = sw16(cmd->len);
    cmd->ctrl_cmd = VOICE_CMD_PLAY;
    cmd->bgm =  VOICE_BGM ;
    memcpy(cmd->msg,buffer,len);

    for (i = 0;i< (len + sizeof(VOICE_CMD)) -1;i++){
        xor ^= xor_buf[i];
    }

    *xor_sum = xor;
//    memcpy(cmd,testBuf,sizeof(testBuf));
    return cmd;
}

static uint8_t readVoiceCmdLen(PVOICE_CMD voice_cmd)
{
    return sw16(voice_cmd->len) + sizeof(uint8_t) + sizeof(uint16_t);
    //return sizeof(testBuf);
}
