2.4GHz:
注意:F1000和F500是FLRC模式下的封包速率,提供更快的調變和更低的延遲,但同時比普通Lora模式有更短的接收距離。這種模式非常適合賽車手。
D500 和 D250 是 DVDA(Deja Vu Diversity Aid)模式下的封包速率。此模式工作在FLRC模式的F1000資料包速率下,透過多次發送相同的資料包,在複雜幹擾的情況下提供更好的連結連接。 D500和D250分別表示同一個資料包發送了兩次和四次。
915MHz/868MHz:
註:D50是ELRS Team900獨有的模式。在Lora模式200Hz更新率下,同一個資料包重複發送四次,接收距離相當於200Hz。
100Hz Full是在Lora模式的200Hz刷新率下實現16頻道全解析度輸出的模式,接收距離相當於200Hz。
配置與綁定
ExpressLRS 使用 Crossfire 串行協定(又稱 CRSF 協定)在 SuperD 分集接收器和飛行控制器板之間進行通訊。以使用Betaflight韌體的飛控為例,介紹其接線和連接埠配置。
SuperD分集接收機與飛控的連接如下圖所示
將飛行控制器連接到 Betaflight 配置器進行基本配置。首先,在「連接埠」頁面,將飛控串列埠(以UART1為例)啟用為「Serial Rx」。
在設定頁面上,將接收器模式設定為串列(透過 UART),並將串列接收器提供者設定為 CRSF。
SuperD分集接收機預設韌體採用ExpressLRS V3.0.0協議,無預設綁定短語。 因此,發射模組的韌體版本必須為ExpressLRS V3.0.0或更高版本。接收器和發射器模組都不應有任何綁定短語。
- 接收機開機、關機3次,每步停頓2秒進入綁定模式;
- 當指示燈開始橘色快閃兩次時,表示接收處於綁定模式;
- 進入電台或發射模組的綁定模式與接收器進行綁定;如果指示燈常亮,表示設備綁定成功。
注意:綁定一次後,接收方會記住自動儲存的綁定短語和裝置。設備再次重新啟動將自動綁定,無需重新綁定過程。
2.4GHz 預設韌體為 ELRS V3.0.0。如果您想綁定遙控器或發射模組,請將其升級至V3.0.0以上版本。如果您想為 SuperD 接收器刷新最新的官方 ELRS 韌體,請將 ELRS Configurator 升級到 V1.5.2 或更高版本。選擇目標裝置“BETAFPV SuperD 2.4GHz RX”。
915MHz/868MHz 預設韌體為 ELRS V3.3.0。正式版本尚未發布。將與ELRS V3.3版本同步更新。然後你可以點擊 最新的 ELRS 配置器每晚運作。 選擇目標設備“ BETAFPV SuperD 900MHz RX”。
附註:915MHz/868MHz 韌體目前為自編譯韌體。
