<br>
<br>
I'm new to python and flask web development.
<br>
I have to realize a data logger using flask. By using another
framework called 'pymodbus', I get some data from
<br>
an energy meter and save that data to a variable called 'crv_data'
(see file attached). This part is working so far!
<br>
<br>
The second part of the project contains the storage of 'crv_data'
to a SQLite-Database. For that, I'm using flask.
<br>
For creating a table with five columns, a file 'schema.sql' (also
attached) is included.
<br>
<br>
If the file 'logger.py' is running, a database is produced with
the desired layout and some data in 'crv_data' is available.
<br>
But there is no data included in the database.
<br>
<br>
I think there is an error in function 'add_entry()' (starting in
line 72 of logger.py file), because if I call the function
<br>
in the infinite loop (line 103), the program stops running.
<br>
Maybe I have to say that I using Beaglebone Black with running
Debian on it.
<br>
<br>
Does anybody have an idea, why the program doesn't work?
<br>
Many thanks,
<br>
Andreas
