I am using a 3DR Radio module for telemetry on TX/RX of the UART connector and I am having trouble setting up the Benewave TFmini
IO17 > White Wire (RX)
IO18 > Yellow Wire (TX)
ARDUPILOT_OPTS="$TELEM1 $TELEM2 $TELEM3"
INITIAL SETUP - Optional Hardware - Range Finder = Benewake TFmini
CONFIGTUNING - Full Parameter List.
RNGFND_TYPE = 20
SERIAL3_PROTOCOL = 9
I’m sure that I’ve not got something set up right here?
Any help would be great. Thanks
I will have one TFmini soon. I expect to use the UART (I use USB for telemetry).
So we can share our experience.
The Raspberry Pi has only one UART. You need to use an USB to UART adapter for the TFmini.
I’m going to try and set it up today with an FTDI-232 cable.
I have it working!
But my sonar range is reading approximately 4 x greater than the actual distance.
Does anyone know how to set the scaling on a serial range finder? I only see m/v setting which is analogue right?
It seems that there was a fix to this on 3.6.2 for the TFmini scaling issure and I am running 3.6.11.
I have spent a lot of time setting up my copter as a single.
Does anyone know if the upgrade will lose any of my settings?
Yes, after updating Ardupilot all settings will be reset. However, you can backup your settings in the Mission Planner:
In the Config/Tuning tab, open the Full parameter list
Choose the Save option in the upper right corner
Then, you can just restore your parameters after the upgrade.
