Chapter 4 stm32+ld3320+syn6288+dht11 realize voice acquisition of temperature and humidity values (Part 1)

The first three chapters , We introduced LD3320、SYN6288 and DHT11 Temperature and humidity sensor , And shared the code information one by one , After getting the code , We can make a simple speech recognition setup , That is, obtain the temperature and humidity value of the current environment through voice commands ,（ But the completion of the project is not up to the normal level , So later I will teach you how to use this program to control the adjustable brightness and color temperature LED The lamp ）.

Start by opening LD3320 and SYN6288 Project folder , We're going to LD3320 Based on the project , hold SYN6288 and DHT11 Transplant it .SYN6288 Speech synthesis module and STM32 The communication between them is through serial port , therefore , We will SYN6288 The serial port driver source code file in the project file is transplanted into LD3320 In engineering documents , The specific steps are as follows .

After porting the serial port source code , We can SYN6288 The function code files that realize the function of voice broadcasting are also transplanted （ The previous chapter mentioned , This function is based on serial communication ）.

open LD3320 Project code , Follow the steps below .

         Operate in the pop-up dialog box , Add the serial port driver of voice broadcast into the project .

          Next , Add the source code file of voice broadcast interface into the project .

        Transplant the two usart and syn6288 Add the file to the compilation path .

Repeat the above operation to syn6288 Also added to the compilation path , The results are as follows .

And then click OK Exit the dialog box .

          Finish the above transplant operation , stay main.c Add... At the beginning usart.h and syn6288.h The header file , And in main() Call in function usart.c Serial port initialization function in , hold STM32 And SYN6288 After the serial port of communication is initialized , We can call  SYN_FrameInfo() Voice broadcast .

        Call directly where you want to broadcast voice information SYN_FrameInfo() Function . As shown in the figure below ,（ In different operations according to different identification codes User_Modification( ) Add our broadcast voice operation in the function ）.

          Compile and then burn the code into STM32 Voice human-computer interaction can be realized .

The code and effects videos are placed in the following links
