【Follow me第二季第3期】进阶任务——示例程序中新增命令打印信息: [复制链接]

 

1、quickstart_ek工程中新建两个文件，分别为menu_dac.h/c:

 

2、menu_adc.c内容如下，主要是进入时，打印提示菜单，然后周期读取数据，如果是1-5打印出相应的字符，如果是0则退出此个菜单：

3、头文件则是声明菜单的接口：

#ifndef __MENU_DAC_H__
#define __MENU_DAC_H__


test_fn dac_display_menu(void);


#endif __MENU_DAC_H__

4、将头文件添加到menu_main.h中：

 

5、在主菜单的列表里添加一条菜单，并把dac_display_menu子菜单函数添加进回调函数：

  【实现效果】

 

按6进入子菜单：

 

按下0又可以回到主菜单。
