List of apps:

1. Take screenshot: Capture screen display to picture file and upload to Dropbox - See configuration for Dropbox upload
2. Dropbox Uploader - Download / Upload files from Dropbox - only need cURL

Quick Install

curl -sL https://raw.githubusercontent.com/neural-display/tools/master/installer.sh | bash -

How to Use

1. Use alone in Raspbian

./take_screenshot

2. Use with Balena Cloud

Please mind to read Balena Getting Started to learn how to create Multicontainer app first. This tools run as a container service in Balena application. Ater you build Balena application succesfully (see a awesome unicorn rise up), follow belows.

On Balena.io, configure Service Variables as belows:

# Dropbox configurations
DROPBOX_SECRET=<Your Dropbox Secret>

# Screenshot configurations, any number that fixed your screen resolution
SCREEN_HEIGHT=1920
SCREEN_WIDTH=1080

• Open Balena Dashboard.

• Go to your application. eg awesome-app

• Click on a device you want to check eg. awesome-dev, chose tools in the Terminal - Selec a target

• Just type ./take_screenshot and voilà :].

Take Screenshot

Small bash script to take screenshot and named output file as format below:

Filename format: <device-name>-<device-id>-<timestamp>.bmp

And use dropxbox_uploader.sh to upload direct to my Dropbox - I will get Dropbox notification when upload finish.

Dropbox Tools

I already download dropbox_uploader.sh for easy to build docker app. You can download the script manually using this command:

curl "https://raw.githubusercontent.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh" -o dropbox_uploader.sh

and edit dropbox config file location

CONFIG_FILE=.dropbox_uploader

Read more in Dropbox Uploader for details.

Balena Dockerfile

I included Dockerfile.template for Balena service for convenient.
