JeVois 1.1 released: live access to microSD over USB, Python 3.5+Python-OpenCV, better SDK

Question

We just released JeVois 1.1

Download the latest microSD image to try out these new features:

• Access the microSD card inside JeVois live over USB as a virtual USB flash drive. Directly edit config files, add training data, retrieve data recorded by JeVois, or install/update machine vision modules without having to physically take out the card.
• Program machine vision modules in Python 3.5 with full Python-OpenCV 3.2.0 support. Combined with the live access to microSD over USB, edit a machine vision module written in Python directly on the JeVois camera without having to remove the card.
• New suite of Ubuntu 17.04 deb packages for developers, should (hopefully!) eliminate headaches with trying to install the jevois-sdk.
• Access a Linux login shell on JeVois, either over the hardware 4-pin serial port, or using serial-over-USB, while machine vision software is running.
• New camera settings for low-light and night vision, using automatic reduction of framerate to increase exposure time.
• And more, see more details.

Answer 1

Hello,

Works great !

Just a simple usbsd, modify python file, restart and you see the result !

I have to think about next improvement ;-)

Many thanks

Answer 2

Very nice.  Implementing usbsd is a major convenience.  Thank you!

thank you guys for the feedback. Just added a script in Github to mount/eject the microSD inside JeVois without having to open a serial terminal and type into it:

- do a git pull in jevois, jevoisbase, samplemodule, etc
- run rebuild-host.sh in jevois to install the script to /usr/bin/
- with JeVois connected to host and not streaming video, try 'jevois-usbsd start' to mount the microSD, then 'jevois-usbsd stop' to release it and reboot.
- now go to samplemodule and try './rebuild-platform.sh --live' which is a new build target to live microSD which will use jevois-usbsd to mount the microSD, then install, then release and reboot.

the script is a bit brittle for my taste now (many assumptions about organization of /media, etc) so I would love your feedback.

Thanks JeVois.  Can you please put a alpha/beta prefixed release of the image to flash to SD for us to try?

well, this is only a script running on the host, so the microSD image is the same. We will post new debian packages with that script in it so you can try it, in the next few days.
