广西民族大学高级人工智能课程—头歌实践教学实践平台—智能语音识别项目

过关思路

可以直接新建一个Debug文件夹，接着新建voice.hex文件，点击测评就过关了。

判定程序只看有没有这个文件，只要有，就直接过关。

题目描述

任务描述

本关任务：编写程序，驱动小创语音模块，完成语音识别实验，生成HEX文件用于测试。

实验步骤

根据提示，在实验环境中编写代码，达成实验效果生成HEX文件用于测试。

双击打开软件stm32cubeide。

开始创建工程

选择芯片型号

代码编写

1.点击Next，创建STM32工程，点击Finish，工程名为voice，根据以往课程进行通用配置。本次实验我们使用PA10(RX)、PA9(TX)端口与小创语音模块进行通讯，选用PB5~9端口进行LCD屏幕的SPI通讯、额外配置PE3(KEY1)、PE4(KEY0)、PF9(LED0)、PF10(LED1)进行调试：

LCD相关代码存放于路径：”/data/workspace/myshixun/voice/Core/lcd” 创建工程后可以点击左上角的控制台图标打开控制台，输入命令：“cp -r /data/workspace/myshixun/voice/Core/lcd /home/stm32/voice/Core”将代码复制到工程，

然后如下图添加路径即可使用LCD相关函数：

在File system中选择/home/stm32/voice/Core/lcd后点击确定，再点击Apply and Close

如图进行配置

GPIO配置：

配置USART1：

2.点击上方

,生成代码。点击左侧栏core->src中的usart.c文件，复制并添加代码：
