IR红外功能,多么基础的功能,但是说来也不简单

因为,小小的红外看似基础,实则设计太多东西了,

从关机涉及Uboot;到内核kernel键码上报;到android键码的实现,小小的功能涉及大大的范围;

(101条消息) rk3288-android8-IR-mouse_旋风旋风的博客-CSDN博客

大家可以看一下我之前的博客可以知道调试过程,下面进入正题:

1.修改代码让uboot实现IR可关机

2.修改代码让关机小窗口可以选中;

 

 

 

 

上述是uboot遥控开机的内容

 下面是关机到uboot

 然后是关机弹窗焦点问题

这个弹窗遥控器是选不中的

         } else {

 然后关机窗口就变了

然后输入法无法选中问题
