Hi all,
I’m developing a frame-work for companion with RPi platform and one of the functions I’d like to implement is to use RPi as FPV cam connected to analog VTX via AV output (as in the figure below)
May you help me in defining how to implement the OSD? Can I use any already installable GCS on RPi (e.g. like mission planner HUD in windows)
thanks
There was as similiar project on EMLID, i dont know if its still active
https://github.com/emlid/navio-docs/blob/master/docs/common/community-projects/SoftOSD.md
+1 to softOSD.
As an observation, recommend using serial rather than USB to connect the fc.
Hi James, why serial and not USB?
Thanks.
I’ll check… but I’m afraid the code is not accessible I could be it will not be usabòe for platform different than NAVIO
Basically the firmware assumes that if connected via USB you are setting up, not configured for flying, so a few things get skipped. USB is entirely possible but I’d always recommend serial if you have one available.
I’m using VRBrain 5.2 and serial ports are both already in use (one for telemetry to GCS and one for telemetry to taranis) so I prefer to use USB. btw I will check and in case decide to quit taranis telemetry
thanks
Are you attempting something like this: https://youtu.be/X_s6ko0hwqE ?
I coded this OSD in python. It runs on a Raspberry Pi and has most of the components you have in your schema - except the VTX. I transmit the video over mobile internet (LTE). The video is also stored on the Pi
I’m searching for an OSD Solution on the Raspberry reading mavlink from Arducopter. I planned it with minimosd but to save an serial would be great.
It seems SOFTOSD is dead but i don’t find a real alternative…
What about your python code? Will you publish it? Any other alternatives for rpi osd???
Hello James,
i saw it and tested the “old” wifibroadcast osd. But the usage is absolutely unclear. Got i to display osd but how to combine with rpicam out? Don’t want the rest of the wifibroadcast or openhd… only ned a osd on rpi for saving serial.
