前言
此面板允許在機載 OSD 屏幕上顯示業(yè)余無線電呼號（或任何其他單個字符串）。它將從 SD 卡根目錄下名為“callsign.txt”的文件中讀取字符串。
5 呼號面板
此面板允許在機載 OSD 屏幕上顯示業(yè)余無線電呼號（或任何其他單個字符串）。它將從 SD 卡根目錄下名為“callsign.txt”的文件中讀取字符串。請注意，默認(rèn)的 ardupilot 字符集需要使用大寫字母才能正確顯示。使用 MAVftp 是一種方便的選擇，可以將文件上傳到 SD 卡，而無需將其從飛行控制器中物理刪除。
！Note
你將在固件 4.1 及更高版本中找到此功能。
6 用戶可編程警告
可以設(shè)置多個用戶定義的警告，當(dāng)達(dá)到或超過警告級別時，這些警告將閃爍相應(yīng)的 osd 面板項。
- OSD_W_BATVOLT-如果低于此值，電池電壓面板將閃爍。0-100V，精度可達(dá)十分之一伏；
- OSD_W_RSSI-如果小于此整數(shù)百分比值，則 RSSI 面板閃爍。0-99%；
- OSD_W_NSAT-如果小于此數(shù)字，則閃爍 #Sat 面板。0-30。
7 使用SITL測試OSD
OSD 功能可以在沒有自動駕駛儀或視頻硬件的情況下，使用軟件在環(huán)（SITL）模擬器設(shè)置進(jìn)行測試(Software In The Loop (SITL) simulator)。按照 SITL 說明設(shè)置仿真環(huán)境。在當(dāng)前源代碼上運行模擬器。
通過在 sim_vehicle.py 中添加以下選項，可以在單獨的窗口中打開圖形 OSD 模擬：
--osd
現(xiàn)在可以通過參數(shù)設(shè)置和配置模擬 OSD。
