【开源】麦克风变声-场景音效

大明哥

主要框架逻辑是  迪文串中屏+解码板 ，通过串口通信控制

视频效果如下：

界面如下：

屏幕代码如下：

void main(){

       INIT_CPU();  //系统初始化

       PORT_Init();//IO口初始化

       T0_Init();//定时器0初始化

       T2_Init();//定时器2初始化

       my_UART4_Init(115200);

       uart_init();//串口初始化

       while(1){

              Uart_Handle_all();

              TenMsHandle();

   Read_0xF00();//数据自动上传

       }

}

#define DwinLocal_addr      0x51

void MicEffectCheck(void)

{

       u8   Read[2];

       u8   Senddata[3];

       Read_Dgusii_Vp(0x2000,Read,1);

       if(!Read[1])

              return;

       Senddata[0]=DwinLocal_addr;

       Senddata[1]=1;

       Senddata[2]=Read[1];

       UART4_SendStr(Senddata,3);

       Read[1]=0;

       write_dgusii_vp(0x2000,Read,1);

}

void MusicEffectCheck(void)

{

       u8   Read[2];

       u8   Senddata[3];

       Read_Dgusii_Vp(0x2001,Read,1);

       if(!Read[1])

              return;

       Senddata[0]=DwinLocal_addr;

       Senddata[1]=2;

       Senddata[2]=Read[1];

       UART4_SendStr(Senddata,3);

       Read[1]=0;

       write_dgusii_vp(0x2001,Read,1);

}

解码板代码如下：
