之前介绍过SYN6288 模块【参考1】,这次配合 ESP32 实现随机生成一个时间,然后通过语音播放出来。
硬件使用的是ESP-WROOM-32 ESP-32S模块,语音模块的 RX 连接到 ESP32 的GPIO17:
- String DataBuffer[11]={{"零"},{"一"},{"二"},{"三"},{"四"},{"五"},{"六"},{"七"},{"八"},{"九"},{"十"}};
-
- //存放转化后的汉字 Unicode值
- char character[40];
-
- #include <HardwareSerial.h>
-
- //根据字符串计算计算出来的送到串口的值
- char output[50];
-
- void setup() {
- Serial.begin(115200);
- Serial2.begin(9600);
- delay(1000);
- }
-
- void loop() {
- Serial.println("generate");
-
- int hh=random(13),mm=random(60);
- String timeStr="";
-
- Serial.print("Generate time: ");
- Serial.print(hh);Serial.print(":");Serial.println(mm);
-
- if (hh>9) {timeStr+="十";
- if (hh>10) {timeStr+=DataBuffer[hh-10];}
- }
- else {timeStr+=DataBuffer[hh];}
- timeStr+="点";
-
- if (mm==0) {timeStr+="整";}
- else
- if (mm<10) {timeStr+="零";timeStr+=DataBuffer[mm];}
- else if (mm%10==0) {timeStr+=DataBuffer[mm/10]; timeStr+="十";}
- else {timeStr+=DataBuffer[mm/10];timeStr+="十";timeStr+=DataBuffer[mm%10];}
- if(mm!=0) {timeStr+="分";}
-
- //timeStr="十二点五十八分";
- //首先输出一次Arduino 原始字符串 UTF8 的值
- for (int i =0;i<timeStr.length()*3;i++) {
- Serial.print(timeStr[i]&0xFF,HEX);
- Serial.print(' ');
- }
- Serial.println(' ');
-
- //将 UTF8 转化为 Unicode
- for (int i =0;i<timeStr.length()/3;i=i+1) {
- character[i*2]=((timeStr[i*3]&0xF)<<4)+((timeStr[i*3+1]>>2)&0xF);
- character[i*2+1]=((timeStr[i*3+1]&0x3)<<6)+(timeStr[i*3+2]&0x3F);
- Serial.print(character[i*2]&0xFF,HEX);
- Serial.print(' ');
- Serial.print(character[i*2+1]&0xFF,HEX);
- Serial.print(' ');
- }
- Serial.println("");
-
- output[0]=0xFD;
- output[1]=(timeStr.length()/3*2+3)>>8;
- output[2]=((timeStr.length()/3*2+3)&0xFF);
- output[3]=0x01;
- output[4]=0x03;
- //把字符串定义搬过去
- for (int i=0;i<timeStr.length()/3*2;i++) {
- output[i+5]=character[i];
- }
- //计算一个校验和
- output[timeStr.length()/3*2+5]=output[0];
- for (int i=1;i<timeStr.length()/3*2+5;i++) {
- output[timeStr.length()/3*2+5]=output[timeStr.length()/3*2+5] ^ output[i];
- }
-
- for (int i =0;i<timeStr.length()/3*2+6;i++) {
- Serial.print(output[i]&0xFF,HEX);
- Serial.print(' ');
- Serial2.write(output[i]);
- }
-
- Serial.println(' ');
- delay(3000);
- }
