Linux Driver?

[Ruben Kertesz]

I had this installed on windows but my machine had to be replaced.

Tried going through the Linux tut here https://github.com/iabdalkader/openmv/wiki/Linux-Installation but when I went to connect, no dice.

I did see that there were a couple of errors along the way when I issued this command:

 $ sudo pip install --allow-all-external --allow-unverified PyGTKCodeBuffer numpy pyserial pyusb==1.0.0b2 Pillow PyGTKCodeBuffer

I had previously updated the camera firmware through windows.

Is there some driver of some sort that isn't getting installed on Linux?

Ubuntu 14.04LTS

Those commands must not fail, otherwise you'll end up missing a package, do you have dev-essentials installed ? also read the errors and see why it fails.

[Michael Shimniok]

Also, after you plug in the camera, issue the following command at the shell prompt:

lsusb

and send the result?  One of the lines should read:

Bus 006 Device 018: ID f055:9800

You may also need to either add your user to the dialout group (to use /dev/ttyACM*) or add an entry to udev

There's a udev rules file included which takes care of that, mentioned in the wiki too.

Thanks. I am looking now. So far, it isn't showing up in the list.
I will try to reinstall and see what commands fail. (hopefully they don't overflow the terminal buffer)

I tried running it again but it says everything is satisfied. Is there a flag I can use to write over the top?

Hmm. I don't have essentials.
I ran

python-dev 
Not
python-dev build-essential

Is that what you are referring to?

That's the OpenMV Cam right there, above.


What happens when you try to connect via openmv-ide.py ? On mine (Mint 13), I click connect and IDE says "failed to connect" then I click ok, click connect again, and it connects.

[Ruben Kertesz]

I don't remember. I'll give it a try tomorrow morning.

Ok, cool, let me know. I'll be on google hangouts on my phone basically all day if you want to IM. Or you can text me at 720-351-8065.

[Ruben Kertesz]

Good news. I found my other OpenMV R5 board and plugged it into my linux box and it works.

That is, it connects. I can "capature" images (slight spelling error) and I can try to execute scripts. However, none of the scripts seem to run.

I get the following traceback

File <stdin> line 31, in <module>

File <stdin> line 15 in find_face

OSError: Could not find the file

Micro Python v1.3.2-110-g077eefd on 1014-11-15; OPENMV1 with STM32F407

You need to save the file into the sdcard or into flash, there is an email from me around the ML about the same thing.

Thanks Jose. I'll take a look

[Ruben Kertesz]

Also, is there a way I can check the firmware. I don't want to update it if it is already up to date.

[Michael Shimniok]

Ruben, that's great! Send me your other board and I'll fix it for you.

Right. You can find the Haar cascade files in usr/data/haar.

The fact that it isn't connecting might be due to the firmware being out of date. It's been updated since I shipped your cameras.

It's pretty simple to update it on Linux. You should just be able to cd into the firmware directory, reset your board into DFU* with the BOOT0 (BOT) and VOUT pins jumpered, then type make.

* you can doublecheck the board is in DFU with lsusb which should display something very similar to this line:

Bus 007 Device 009: ID 0483:df11 SGS Thomson Microelectronics STM Device in DFU Mode

[Ruben Kertesz]

I'm not sure what to do with the files in the Haar directory.

I just copied a python script to a microsd card in the top level directory and presumably it ran, but the GUI doesn't refresh with any frames or squares around my face or anything like what Ibrahim showed in his example videos. Is there a way I can get that?

[rub...@gmail.com]

I stand corrected. I simply added the SD card and ran the video example and te mjped streamer examples and they streamed images. I just thought that the facedetection and other python example scripts would also include streaming to the framebuffer.

Many of the demos (fb_viewer.py, face_tracking.py, blob_detection.py, and others) are supposed to stream to the buffer.

What happens when you open fbviewer and run it? Can you take a screenshot and attach it to your reply?

Are there any errors at the command line?  What is the contents of /var/log/syslog ?

You'll need to convert the xml files to bin (*.cascade) files first, choosing the number of stages you want (more stages =more accuracy but slower and bigger) so something like this:

python2.7 ./openmv-cascade.py data/haar/haarcascade_frontalface_default.xml 13

And then copy the .cascade file to the uSD and run facedetection.py

Everything should show on the framebuffer, the IDE just keeps garbing the framebuffer, check the output message maybe some script fails, also mjpeg_streamer needs WiFi
