入门任务：搭建环境，下载调试示例程序，Blink，按键
此任务的目的是搭建开发板的软件编辑环境、初次编译示例程序，以及在例程中增加按键控制LED的程序并且下载测试验证。
由于电脑原因无法通过github下载e2 studio的安装包和例程代码，所以请网友下载后放在了百度网盘提供给需要的网友参考
setup_fsp_v5_6_0_e2s_v2024-10.exe
链接: 提取码: 9p35
ra-fsp-examples-master.zip
链接: 提取码: p45p
下载安装包（如下图）后按照步骤安装软件即可
安装成功并且打开时软件如下图
接着导入参考例程
配置串口调试终端
初次编译开发板提供的quickstart工程文件
编译后进入调试模式，点击下图调试。并且将Micro usb从USB full speed接到DEBUG，如下图
Blink、按键程序测试
在参考例程中增加按键开关控制LED闪烁频率的功能，搜索gpt的中断回调gpt_blinker_callback
找到LED工作状态控制的函数
LED的亮度s_duty取决于变量g_pwm_dcs，通过修改此变量更改LED的亮度并对应的修改数组长度和增加宏定义
修改完成后保存并编译然后下载到开发板中
测试环境和测试视频如下：

基础任务：quad-spi flash和octo-spi flash配置及读写速度测试；DAC配置生成波形及性能测试;
测试quad-spi flash和octo-spi flash读写速度对比，如下图
进入主函数（main.c）找到菜单任务
通过菜单任务逐布找到菜单选项部分程序，也就是串口调试页面的菜单选项，如下
进入spi测试部分程序
