掌控板功能展示菜单制作
初衷：通过菜单调用展示掌控板的基本硬件功能。掌控板载传感器及相应执行器如下：
[*]三轴加速度计MSA300,测量范围:±2G
[*]光线传感器
[*]麦克风
[*]3 颗全彩ws2812灯珠
[*]1.3英寸OLED显示屏，支持16*16字符显示，分辨率128x64
[*]无源蜂鸣器
[*]支持2个物理按键(A/B)、6个触摸按键
[*]支持1路鳄鱼夹接口，可方便接入各种阻性传感器
设计功能菜单项目有１２个，列表如下：
[*]显示环境声音
[*]显示环境光线
[*]显示三轴加速度计各轴值
[*]显示物理按键值
[*]显示触摸按键值
[*]无源蜂鸣器奏乐
[*]oled随机显示点线圆
[*]oled显示你好世界
[*]变色灯
[*]流水灯
[*]呼吸灯
[*]内部文件系统
掌控板oled液晶屏无法一次展示所有项目内容，故需分页展示。
考虑人机关系特点，设计掌控板菜单按键组合如下：
[*]按键A功能下移
[*]按键B功能上移
[*]触摸P开始
[*]触摸N结束
[*]触摸Y功能翻页下移
[*]触摸O功能翻页上移
[*]触摸T选定当前功能展示
[*]触摸H选定当前功能结束
编写烧录程序后效果如图所示：
相关程序代码如下所示（各位同仁可以根据兴趣自行添加修改菜单项目）：
