前言
此面板允许在机载 OSD 屏幕上显示业余无线电呼号（或任何其他单个字符串）。它将从 SD 卡根目录下名为“callsign.txt”的文件中读取字符串。
5 呼号面板
此面板允许在机载 OSD 屏幕上显示业余无线电呼号（或任何其他单个字符串）。它将从 SD 卡根目录下名为“callsign.txt”的文件中读取字符串。请注意，默认的 ardupilot 字符集需要使用大写字母才能正确显示。使用 MAVftp 是一种方便的选择，可以将文件上传到 SD 卡，而无需将其从飞行控制器中物理删除。
！Note
你将在固件 4.1 及更高版本中找到此功能。
6 用户可编程警告
可以设置多个用户定义的警告，当达到或超过警告级别时，这些警告将闪烁相应的 osd 面板项。
- OSD_W_BATVOLT-如果低于此值，电池电压面板将闪烁。0-100V，精度可达十分之一伏；
- OSD_W_RSSI-如果小于此整数百分比值，则 RSSI 面板闪烁。0-99%；
- OSD_W_NSAT-如果小于此数字，则闪烁 #Sat 面板。0-30。
7 使用SITL测试OSD
OSD 功能可以在没有自动驾驶仪或视频硬件的情况下，使用软件在环（SITL）模拟器设置进行测试(Software In The Loop (SITL) simulator)。按照 SITL 说明设置仿真环境。在当前源代码上运行模拟器。
通过在 sim_vehicle.py 中添加以下选项，可以在单独的窗口中打开图形 OSD 模拟：
--osd
现在可以通过参数设置和配置模拟 OSD。
