1. 源由

在《Open FPV VTX开源之硬件规格及组成》章节中，已经基本介绍了产品组成。

为了让其正常工作，其组合大致有以下几种方式：

• Open FPV VTX + Ardupilot
• Open FPV VTX + betaflight
• Open FPV VTX + inav
• Open FPV VTX + PX4 //个人来说，用的比较少

为了让其正常工作，在第一次上电之前需要做一些准备工作，本章就是为了这些准备工作编写的。

2. 连线

2.1 飞控

Open FPV VTX  -- toFC -- Flight ControllertoFC:- pin1: VCC(7.4~26V)  ---- FC VBat+- pin2: GND  ------------- FC GND- pin3: UART_RX1  -------- FC OSD_TX1- pin4: UART_TX1  -------- FC OSD_RX1- pin5: GND  ------------- FC GND- pin6: NC

注：选择笔者第一台FPV无人机使用的Holybro Kakute F7 and KAKUTE F7 AIO串口1作为OSD的UART。

2.2 调试

由于DEBUG线是预先做好的，这里就不一一对应做连接，直接从逻辑上进行示意。

Open FPV VTX  -- toDebug --  GND/UART_TX0/UART_RX0 --  USB -- PC Serial Console|+------  TP_LAN/TN_LAN/RP_LAN/RN_LAN  -- Ethernet  -- PC SSHtoDebug:pin1: TP_LANpin2: TN_LANpin3: RP_LANpin4: RN_LANpin5: GNDpin6: UART_TX0pin7: UART_RX0

3. serial

serial环境就是类似PC的BIOS阶段，主要用于低层次升级固件版本，可能会导致变砖。若真的变砖就需要其他JTAG工具，比如：J-Link。

注：调试版通常情况下串口驱动是默认的，请仔细查看驱动是否正确安装。

4. ssh - linux

ssh环境就是OpenIPC fpv系统运行环境，应用软件都跑在这个环境下，可以升级软件或者固件。

5. PixelPilot出图

OpenIPC主要基于wfb-ng软件构建底层加密通信链路，基于该链路进行数据（视频、电传等）传输。

地面端软硬件有很多搭配方式，大体上有以下几种：

• Android(PixelPilot): 手机/平板/电视盒等
• Windows PC: fpv4win、openipc-configurator
• Hi3536
• Radax 3W/3E
• Jetson Orin(jetson-fpv)

从购买天空端产品的角度，拿到产品首先要确保快速出图。

• PixelPilot.apk

或者找厂家要手机端最新的软件，因为这个是最为便捷的方式。

默认配置+厂家配置:

• Channel: 60
• 厂家gs.key //请向厂家获取

自拍照

6. 总结

总的来说，第一次上电、出图并不复杂，但是一定要切记！！！重要的事情说三遍！！！

• 注意数字图传的正负极！！！
• 注意数字图传的正负极！！！
• 注意数字图传的正负极！！！

信号线反了，可以重新调，但是正负极接错了，可是要烧的！！！

不出图时，需要注意的一个关键点：供电电压

• 图传功率比较大，从设计规格上是3S ~ 6S
• 换言之可以直接接在动力电池上
• 有些PDB板/飞控板降压出来的电源可能带不起来

8. 补充

8.1 8812AU网卡

笔者采用了一张8812AU的网卡，作为wfb-ng的地面端接受wifi。

8.2 DEBUG串口部分乱码

当有线网口与路由器连接的时候，DEBUG串口会出现部分乱码情况。若网线拔掉，一切正常。

8.3 偶尔启动卡住

[USB] init squelch level 0x0

断电重启后，可以解决。怀疑上述问题与USB设备或者驱动有关，网卡功率不足导致初始化异常。

==》是否可以考虑网卡上电时序靠后，先让内核/文件系统都跑起来，进入IDLE之后，再来考虑启动大功率的网卡？

8.4 花屏、丢包严重

• OpenIPC S30KQ video exception
