data logging software

[ghost]

i have a imax b6 and a ftdi converter connected to the temp port i wand to make a discharge curve from a battery what software can i use to do that?

[specing]

GNU Octave, Libreoffice, Gnuplot, ....

[stawel]

I'll add two more:

1. LogView (ini files: https://github.com/stawel/cheali-charger/tree/master/utils/LogView)
2. cheali-logviewer (very simple python script, uses matplotlib)

[ghost]

i tried LogView and could not get it to work how do i use cheali-logviewer

[stawel]

you have to save the UART output to a file and just run: $ ./cheali-logviewer your_file (works on linux)

i tried LogView and could not get it to work...

First of all, in all cases, you need to be able to see the chargers output as a human readable text (use "screen" on linux or "PuTTY" on windows).

You probably tried "LogView studio" it's not the same as LogView, some people where able to run cheali-charger with "LogView studio" you will probably find some info on the chali-chargers mailing list.

this is what logveiw shows in the serial logger other programs like PuTTY work the charger is set to 57600 baud rate is that the correct baud rate?

And I’ll add another: DataExplorer

[stawel]

is set to 57600 baud rate is that the correct baud rate?

it looks like it is, see: https://github.com/stawel/cheali-charger/blob/master/utils/LogView/ChealiCharger_6cell_1.0.ini#L35 you can also try other baud rates, just change line 35 in the ini file.

this is definitely not human readable....

Hi! I have same problem. In Arduino IDE port monitor i get nice readable string and in LogView i get something strange like what Ghost have. Maybe something with encoding? I think LogView can't understand ASCII correctly. But why?

[UPD] SOlVED for me I was inattentive and put .ini in "...Program Files\LogView V2\Geraete\" folder, this is incorrect .ini should be placed to "...Users_YOURUSERNAME\AppData\Roaming\LogView\Geraete\OpenFormat". Another thing LogView work on baudrate 9600 (for me at least), don't forget to change this value in .ini file.

Logview has you sorted https://youtu.be/rwSv8El2ahg http://www.logview.info/forum/index.php?pages/eng/

Sorry for the off-topic, but I have such question: Will it be possible to monitor battery temperature through the temperature port and at the same time monitor/log all values (current, voltage and temperature) through this temperature port?

@xa0c

Will it be possible to monitor battery temperature through the temperature port and at the same time monitor/log all values (current, voltage and temperature) through this temperature port?

it is possible but you have to modify your charger, see: https://github.com/stawel/cheali-charger/blob/master/docs/settings/settings.md#uart-settings "separ: temperature connector and UART are separated"
