避免发送重复的功能请求

  • 我已查看所有打开的 Issues，确保这个功能没有被提出过

您遇到了什么问题？

经常擦写词典笔数据会导致内部 emmc 芯片老化，添加此功能可帮助用户获悉 emmc 老化情况、判断预期寿命

您认为还缺少什么？

通过读取 /sys/kernel/debug/mmc1/mmc1:0001/ext_csd，截获第 537 - 538 位数字 / 字母，再进行对应百分比的转换，显示在系统设置的存储或关于菜单中。检测可由开机自启或手动点击触发。

就像下面这条命令一样

[root@YoudaoDictionaryPen-624:~]# cat /sys/kernel/debug/mmc1/mmc1\:0001/ext_csd | cut -c 537-538
