--- 配置开机键长按弹起和短按弹起的功能.
|
|||
|
|
-- 如何定义长按键和短按键，例如长按键判断时长为3秒：
|
|||
|
|
-- 按下大于等于3秒再弹起判定为长按键；
|
|||
|
|
-- 按下后，在3秒内弹起，判定为短按键
|
|||
|
|
-- @number[opt=3000] longPrd 长按键判断时长，单位毫秒
|
|||
|
|
-- @function[opt=nil] longCb 长按弹起时的回调函数，如果为nil，使用默认的处理函数，会自动关机
|
|||
|
|
-- @function[opt=nil] shortCb 短按弹起时的回调函数
|
|||
|
|
-- @return nil
|
|||
|
|
-- @usage
|
|||
|
|
-- powerKey.setup(nil,longCb,shortCb)
|
|||
|
|
-- powerKey.setup(5000,longCb)
|
|||
|
|
-- powerKey.setup()
