/*
|

* 函数名称 : LED_Breathing_Light
|

* 功能描述 : LED呼吸灯驱动，需放在100us时间片中，每20ms改变一次占空比。
|
||
模拟人体呼吸，吸气和呼气各占1.5s，人眼的图像滞留时间0.04s（1/24帧画面）
|
||
按最快0.04s（40ms）。亮20ms，灭20ms，人眼看到的应该是一直亮。
|
||
呼吸灯，就是改变这40ms中，亮和灭所占用的百分百。
|
||
1500/20=75个周期，40ms/75=266us。75个变化周期中，每个周期增长1个单位266us，
|
||
|
||
75个周期刚好是40ms，这样就能达到全亮，反之全灭。
