Not working

[FPSUsername]

Hello, I have an issue and it doesn't work at all:

https://pastebin.com/1DxVr8Rp

The first conversion is done by replacing:
import dbfread -> from dbfread import DBF
dbfread.open( -> DBF(

The second conversion is with the dbf2json file unmodified

Please update this as soon as possible

The problem is probably in https://github.com/olemb/dbfread/ not my code.

Can you provide some more info?

• what version of dbfread is installed? I'm using an older version of dbfread (1.0.1) in my requirements file
• can you upload your dbf file? It seems like the version of dbfread you are using can't read it, maybe there is something wrong or a newer version of dbfread would be able to read it
• try installing newer dbfread and see if it works (assuming you are using 1.0.1)

I'll re-open the ticket when you reply.

I believe that I use the latest version available. I will downgrade to 1.0.1 as soon as I can.
I wrote an issue ticket here: Polyconseil/libcanardbc#2
That is the tool that I can use with caneton (DBC to JSON), but it has an issue with converting extended frame ids. I also tried to convert with canmatrix and that does the job, but it is sorted differently, so caneton can not use it.

I used busmaster to convert the DBC file to a DBF file

I'm not going to lie, I don't know what any of those software packages you are talking about are.

I can tell you that dbfread 1.0.1 on my system doesn't like the file you uploaded, though.

Upon looking at the DBF standard a bit (http://www.dbase.com/KnowledgeBase/int/db7_file_fmt.htm) I see that field type E isn't defined there, which I presume is the "extended frames" you are talking about. dbfread is erroring about a field type 'e' not being known.

Newest dbfread (2.0.7) doesn't work either (the following was tested with 2.0.7):

(dbf2json)eastein@amontillado ~/git/dbf2json :) master  $ !./dbf2
./dbf2json /home/eastein/Downloads/V10_CAN_ime.dbf

I'm also not sure what libcanardbc has to do with my software (which is just a very simple wrapper around dbfread).
