2. ADC 采样代码 我的麦克风测试台 如果您还没有这样做,我强烈建议您在 GitHub 上克隆 Raspberry Pi 的pico-examples库。这是我开始使用的所有采样代码的地方。以下代码的很大一部分来自此存储库中的 dma_capture 示例。 我将通过我的软件的一些关键元素来解释发生了什么。您可以在代码部分找到完整的程序。
准备开发环境首先，你需要搭建好Pico的开发环境，这包括安装Raspberry Pi Pico SDK、C/C++编译器（如GCC）以及CMake。编译与运行示例进入pico-examples项目的根目录，使用CMake生成构建文件。然后，利用构建工具（如make）编译示例程序。编译完成后，你将得到编译好的二进制文件，接下来就可以将其上传到Pico开发板进行运...
