bitplan / can4eve Goto Github PK

Hey,
I tried your code obdtest.py
But I get the error above.
screen /dev/rfcomm0
and manual input everything works but somehow your code throws this error.
Anyone the same problem?

in preparation of #9 allow to manually restart the OBD connection (essentially combining the OBD/halt and OBD start with log menu clicks. Count the number of restarts and display it.

The system should

1. try to connect to the vehicle via the specified OBDII device connection
2. try to read the VIN according to the specified vehicle group
3. create a report according to the specified OBD-II parametes of the the vehicle group e.g. ODO, SOC, Battery Capacity readable with a calculation program (csv format)

It should be possible to switch the screen to "night mode" - making sure that the display is not being to bright.
see e.g.
https://stackoverflow.com/questions/49159286/make-a-dark-mode-with-javafx

It would be nice to switch on this mode when it get dark:

• e.g. by using the cars sensor for darkness
• e.g. by comparing the current time to the sunset/sunrise time and switching approapriately.

Since both options need some configuration the mode will be available on the push of a button for the time being.

Electric vehicles will hopefully have a major market share in the near future.

As of today quite a few of the electric vehicles on the market have no or inadequate in-car applications. Remote functionality is more often than not limited or lacking.

To get the most ouf of their cars users have to resort to third party software that might be

• closed source
• limited to their vehicles

can4eve intends to offer a solution that is

• open source
• open for different vehicles

The functionality of the project shall be driven by the user needs and not so much by technical aspects. You are invited to raise your voice by adding issues to this project.

More often than not the frames per second rate will drop to zero due to some communication issue with the OBD adapter.

In this case manually restarting the connection often helps.
An enhancement would be to automate this but keep track of the number of restarts (see tracking the number of buffer overruns).

When the can4eve is started the tab should be shown that was active when it was last switched off.

Can4eve shall have support for the triple group of cars that share a common set of OBDII-Pids.
This group of cars does not have an in-car software supplied by the manufacturer.

The OBDII pids as outlined in http://cantriplet.bitplan.com/ shall be supported.

On Raspbian Buster OpenJDK 11 is installed by default.
Even after installing Open JDK 8
the message :

WARNING: Error java.lang.RuntimeException:java.lang.UnsatisfiedLinkError: com.sun.glass.ui.gtk.GtkApplication._isDisplayValid()Z

appears in the log.

https://stackoverflow.com/questions/53744923/java-lang-unsatisfiedlinkerror-com-sun-glass-ui-gtk-gtkapplication-isdisplayva discusses this issue.

A workaround is to uninstall libopenfjx-jni

sudo apt-get remove libopenjfx-jni

Still the display is not showing correctly

Hello
I'm trying to use this software to get a report about my i-Miew.

According to the docs and reading some of the code, I thought this syntax should be correct:
java -jar can4eve.jar --conn /dev/ttyUSB0 --baud 500000 --report report.csv
but i get the output

(I'm not that familiar with Java.)

Just running
java -jar can4eve.jar -h
works fine, I get the help text.

My environment is Ubuntu 22.04, openjdk-8-jdk and an OBDLink SX.
I suspect I just got the parameters wrong.

Please let me know if you have any tips or answers :)
