SAKSHAT提供的LED使用方法

当前SAKSHAT为我们提供的方法参考：http://wiki.nxez.com/saks:sdk:libraries:led74hc595

这里就直接摘录了，以下是创百科的内容:
74HC595 芯片驱动下的 LED 灯组类，控制一组 LED 工作。 方法

初始化对象，设置引脚和触发电平（高电平或低电平触发）。pins 为 IO 引脚数组。

返回当前驱动数码管的IC对象。

返回当前 LED 的工作状态。true 或 false。index 为 LED 编号，从 0 开始。

返回当前 LED 灯组的工作状态的数组。

设置 LED 灯组为全部点亮状态。

设置 LED 灯组为全部熄灭状态。

设置当前 LED 灯组的第 index+1 个 LED 的状态为点亮。index 为 LED 编号，从 0 开始。

设置当前 LED 灯组的第 index+1 个 LED 的状态为熄灭。index 为 LED 编号，从 0 开始。

设置当前 LED 灯组的点亮状态。status 为布尔型数组。status 中的元素也可以为 None，表示不改变该元素位置的 LED 状态。
