|
||
* meow_ui_sys.c — SDK 内置系统状态读取器 + 全局状态栏（A-0 核心）。
|
||
*
|
||
* 职责：
|
||
* 1. 状态读取器：读 /sys/class/power_supply/（电量/充电）、WiFi operstate、
|
||
* 蓝牙实上电、音量（/usr/data/meow/settings.conf 的 audio.volume，与 launcher
|
||
* 同源单点）；时钟在绘制时现取 localtime。1s 轻刷，蓝牙 30s 缓存。
|
||
* 2. 全局状态栏绘制：把时钟/电量/WiFi/蓝牙/音量画进 back_buf 顶部 MUI_SBAR_H 行；
|
||
* 由渲染后端 present() 前置调用（z 最顶），非全屏可见。
|
||
* 3. 显隐/全屏状态 + 公共 API（meow_ui_set_statusbar / set_fullscreen / ...）。
|
||
*
|
||
* 注意：所有读取在事件循环主线内做（无独立线程），1s 频率同步读取 sysfs/小文件，
|
||
* 开销可忽略；蓝牙 hciconfig 为 popen(spawn) 较贵，仅 30s 刷一次并缓存。
