Betaflight Firmware
Our SBUS bridge is intended to be used together with flight controllers which are used in first person view (FPV) racing. More or less all common flight controllers used in FPV racing are able to receive SBUS commands and can therefore be used together with our SBUS bridge. On these flight controllers we use the open-source Betaflight firmware since it is easily and transparently configurable.
To flash and use this firmware, you first need to install the Betaflight Configurator by following the steps in their installation instructions.
Before you start flashing the firmware, note that we provide the parameters for version 3.1.7 so make sure to install this version otherwise the parameters might not be compatible. To flash the Betaflight Firmware onto your flight controller, first do the setup as described here and then follow this tutorial.
Some of the parameters set in the SBUS bridge need to correspond to the settings made on the flight controller in the Betaflight Firmware.
We provide the Betaflight parameters that should be used together with the default settings of the SBUS bridge.
To apply these parameters, connect your flight controller to your computer with an USB cable, then start the Betaflight Configurator and press Connect in the top right corner.
Then navigate to the CLI tab which should bring you to the following view:
Then copy all the text from the parameter file we provide with the SBUS bridge, paste it into the command line in the CLI tab of the Betaflight Configurator and hit Enter.
Wait until all the parameters are set, then type save into the command line and hit Enter.
The flight controller will reboot and should be set up to be used with the SBUS bridge.
If everything is connected as described in our wiring guide, you should also be able to monitor what the SBUS bridge is sending by navigating to the Receiver tab in the Betaflight Configurator once the SBUS bridge is running.
Betaflight is able to log flight data which might help you for debugging and filter tuning etc. To analyse flight data you may use the Blackbox Log Viewer which you can install by following their instructions. An example on how to log data, analyse it, and tune filters accordingly can be found in this tutorial. We recommend doing such a filter tuning once you build a new quadrotor.
