digiview-sbc's Introduction

DigiView SBC

DigiView SBC is a linux image that allow you to get a Live preview from your DJI FPV goggles (V1 & V2) on a single board computer.

This is currently an alpha release with minimal features for the Raspberry Pi. It runs on Pi 2B or better, and can also be modified to run on Pi Zero (expect significant latency on the Pi Zero).

Download

You can download the Alpha Release here

Instructions

To get the best results :

Power on our Raspberry Pi and wait for it to boot fully.
You must have a monitor of some kind connected to the SBC before booting the Pi.
Power on your googles.
Power your drone.
Wait for the link to be established.
Plug the USB cable into a USB port your Raspberry Pi.
Streaming is triggered when the Goggles are connected to the Pi via USB, so you should see video shortly after plugging in.
If video latency is poor or image quality is bad, try replugging the USB.
It is strongly recommended that you plug/unplug the Pi end of the cable: you would rather wear out the connector on the Pi than your goggles!

Pi Zero Instructions

In order for the Pi Zero to boot, you must change the amount of RAM dedicated to the GPU:

Connect the SD card to your PC.

In the Boot partition, open config.txt and change this:

gpu_mem=512

To this:

gpu_mem=384

Advanced User Instructions

If you want to log into the pi, you can connect a mouse and keyboard. Right-click on the desktop and open the terminal emulator.
The default username is fpvout. The default password is fpvout.
The pi user is not being used, but does exist. It's password is also fpvout.
SSH is enabled by default, but you will need to add a wpa supplicant file to the boot partition to connect to Wi-Fi.
There is no desktop environment on the image - this is intended to turn your SBC into an appliance that requires no user input for normal operation.

If there is any issue, please check on our Discord server, some people might help you there. You can also consult the DigiView Wiki.

Known Issues

Do not plug into the Pi until after video is showing in your goggles.
If you need to power cycle the air unit, you may need to replug the USB cable in order to re-establish the stream.
You might need to set Autotemp off on your Vista/Air unit to get it to work.
It may work best in 50mbps mode.
Some small monitors have squeezed/stretched video on Pi 3B+.
Need to disable hibernate/sleep so the display doesn't shutdown during flight.

Development

We will add more info here later, but broad strokes are:

The Pi image is based on Raspbian Lite.
The core components that make DigiView SBC are fpv-c, Gstreamer and Hello_Video (Pi version only).
Auto-start on USB is accomplished via a UDEV rule that triggers the GoggleConnect service, which starts a bash script that initiates the stream.
A tutorial for building your own version from scratch is planned for a future date.
Jetson Nano 2gb, and RockPi 4 images are also in development.

digiview-sbc's Issues

Can we replace `fpvout` with `~` so it doesn't depend on a default username?

Thoughts on this? I can implement but didn't get far enough to see if this was a requirement

Support OSD Using Open TX Telemetry

Feature Request

Since the DJI goggle do not support sending OSD data live while using video out, telemetry data from an Open TX could be used instead to get this information. The transmitter would either be plugged in or connected with Bluetooth.

GPIO Monitor with touchscreen not working

Hi,

I'm trying to make it working on my RPi 4B with a 4" touchscreen monitor connnected with GPIO.

I'm using your .img , I need to install monitor drivers after the first power up to see something in the display but after that I cannot see any Digiview background image on screen , only the prompt of the fpvout user.
Maybe something in the drivers broke Digiview ?

My display is a 4" and the drivers I installed are here:

git clone https://github.com/goodtft/LCD-show.git

and I used :

./MHS40-show

after that and one reboot the display started working but I got only a prompt and if I try to start even manually fpvout-start.sh it says:

fpvout@FPVOut:~ $ /home/fpvout/fpvout-start.sh
unable to open device, or device not found
try running as root (with sudo)

feature: dvr

Has anyone considered a basic dvr function? It looks like there is a spot in the (literal) pipeline where it has effectively standard mp4 video that could be diverted to a file as well as playback.

Connect USB storage, allow system to automatically mount it
When goggles attached, if usb storage is present, send it to a file as well as the player: | tee /storage/dvr-2220.mp4 |
During streaming, automatically run sync to flush the write cache periodically

Alternately:

OUTFILE=/dev/null
- When storage is detected, OUTFILE=/storage/dvr-2221.mp4
Include | tee ${OUTFILE} | in the pipeline. This has a very minor performance cost for non-dvr playback, extraneously sending the stream to /dev/null
Still run the periodic syncs during streaming, which shouldn't impact except in dvr mode. (Ideally few/no writes should be going to the system device.)

In both approaches, closing the stream will automatically close the file. The periodic sync should defend (barely) against corruption on power-off, while still allowing a reasonable write cache. Corruption risks are primarily to the DVR storage, rather than the system volume.

I might hack something together if there is any interest. Having a second screen is huge for outreach where we fly but I don't want to lose my dvr

Composite video out

I had enabled composite video out (via 2.5mm jack) on Raspberry Pi OS and it worked just well

After installation of DigiView-SBC image I can't enable the composite video out now.

Please tell me is it in theory possible to use raspberry as a digital to analogue converter using composite video out or there is some limitation?

dual hdmi out pi4

hi! I am using this with a pi4 and only one hdmi output is showing the feed at once, the other just shows "digiview" is there a way to have them mirrored?

preblem to shut down, and sd card corrupted.

Hello,

first of all, thank you for your work it's great. on the other hand I have a problem: when I turn off the Pie with the mouse, or with a command, the sd card and the image are corrupted. I have to redo the image. however I turn off the Pie well, only the red LED remains lit when I cut the power. I don't understand why, I tried everything, and I have to redo the image every time I turn off.. please help me!
thank you in advance,
AureL
