Question about building project

[denny61302]

Hi, I try to implement your project on my new BBBlack.

But, I have question about which OS you use debian or ubuntu?, and how to install OpenCV currently?

Hi Denny, I'm using Debian and OpenCV from Debian repository. You can install it using "apt-get" Walter 2018-05-31 8:26 GMT+02:00 denny61302 <[email protected]>:

Hi Walter

Thanks for your reply.

Right now I success building up the project, however I have another question about I2C setting.

Which I2C did you use I2C1 or I2C2, and how could I change it?

[Myzhar]

Good question. I used the default I2C exposed by BeagleBoneBlue.

You can find it here:

Lepton3_BBB/grabber_lib/Lepton_SDK/src/bbb_I2C.c

Line 135 in 368fdd9

leptonDevice = open("/dev/i2c-1", O_RDWR);

It should be better to expose it as a configuration parameter at execution time instead of hardcoding it

Hi Walter

I still have problem to run your project.
When I try to use opencv_demo, my I2C didin't work, however I can build and run example from official project (https://github.com/groupgets/LeptonModule/tree/master/software/beagleboneblack_video).

Is there something special setting on your BBBlue pins definition?

[Myzhar]

You must verify bbb_I2C.h and bbb_I2C.cpp
They are made to use I2C on the BeagleboneBlue, I do not know the differences with the Beaglebone Black

Thanks Walter

Right now, I can run opencv_demo and capture video.

Then Can I use VLC on Window to stream video from project bbb_life_tracker ?

I am sure that my Window UDP get some data from BBBlack, but VLC player can't show the video.

The gstreamer demo allows to watch video also in vlc
