Chapter II use of syn6288 speech synthesis module

        SYN6288 Speech synthesis module is a module for broadcasting sound , At present, most of the human-computer interaction work of the graduation project is entrusted to OLED、LCD Wait for the screen to display , If you can use voice broadcast instead of screen display , Or participate in human-computer interaction with screen display , Then your design effect will be more novel .SYN6288 The method of using speech synthesis module is very simple , The following figure is one I often use SYN6288 Speech synthesis module , I won't show the electronic components on the back , Interested students can learn about it through the information link below . In the figure ,SYN6288 Voice synthesis module lead out 7 One pin , But we only use four of them , They are connection 5V Of VCC Pin 、 Grounded GND Pin 、 Serial port communication with MCU TXD and RXD Pin .

         Let's talk about STM32F103C8T6 And SYN6288 Communication code of speech synthesis module , It is suggested that interested students can raise funds with their roommates , According to the wiring diagram provided in the data , DuPont line STM32F103C8T6 And SYN6288 The modules are connected , Re pass Jlink or STlink Burn the code into STM32 You can see the effect in .

        delay_init( )  Initialization delay function , After executing this statement ,18-21 The delay effect of the line will be accurate .

        NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2) Set interrupt priority group .

        USART3_Init(9600)  Initialize serial port 3 function , The baud rate is 9600, After this code is executed , We can call 16 Yes SYN_FrameInfo( ) Function to let the speech synthesis module send “ This is bisher's escape ” It's the sound of .

        SYN_FrameInfo(2, "[v9][m0][t5] This is bisher's escape ")  This line of code realizes the sound function , The sound content is “ This is bisher's escape ”, If you want to change the content of pronunciation , Just modify the function brackets The green mark The Chinese content of , Then compile and burn the code into STM32 that will do .

         Careful students will find out The green mark There is a string in front of the Chinese content of  [v9][m0][t5]  Such a string , They have their own functions , among  [v9] The function of is to make the volume of the broadcast sound be the second 9 Level ,[m0] The function of is to mute the background music ,[t5] The function of is to increase the sound speed of the broadcast to the highest , Refer to the following figure for details. . and SYN_FrameInfo( ) The first parameter of the function is the background music selection (0 It's no background music ,1~15 Represents different background music when speaking ), Said so much , Just start with this module , Modify the parameters mentioned above by yourself , Then compile and burn into STM32 You can see the effect intuitively .

        18-21 The function of line delay is to make the program wait for the voice synthesis module to broadcast the sound information , If the delay is too short , There will be a phenomenon that the next sound message will be broadcast before the current sound is broadcast .

         Since then, the code explanation has been completed , Students who want to know the specific implementation process of each function can download the code at the bottom of the article .

         When our design uses SYN6288 Speech synthesis module , Just know the function marked in red above , You can easily transplant the linked code into your own design code , In later chapters , I will show you .（ The premise is that the master of the design MCU choose STM32F103C8T6）
