MicroPython动手做（17）——掌控板之触摸引脚

1、触摸开关
是科技发展进步的一种新兴产品。他一般是指应用触摸感应芯片原理设计的一种控制开关，是传统机械按键式开关的换代产品。能实现更智能化、操作更方便的触摸开关有传统开关不可比拟的优势，是智能产品的非常流行的一种发展性开关。触摸开关是电子取代机械的又一成功应用。触摸开关没有金属触点，不放电不打火，大量的节约铜合金材料，同时对于机械结构的要求大大减少。它直接取代传统开关，操作舒适、手感极佳、控制精准且没有机械磨损。同时，触摸开关更有人性化的关怀，可以自己选择开关上的文字提示，个性化的文字标签呈现出液晶显示的效果，水晶面板发出淡淡的微光，让深夜不再是完全的漆黑，足以让人形成方位和轮廓感。

程序中依次从左到右分别为touchPad_P、touchPad_Y、touchPad_T、touchPad_H、touchPad_O、touchPad_N，可以通过它们下发命令。

touchPad_.read()¶描述：返回触摸引脚 touchPad_P/Y/T/H/O/N 的值
