STWIN.box - Getting data without generating .dat files with the tfp-sns-datalog2 repository

[janco_tianno]

Hi everyone,

 

I have a STWIN.BOX (STEVAL-STWINBX1) and I have played around with the code examples in Python provided on the tfp-sns-datalog2 repository. The idea is to use this device to provide readings to a Raspberry Pi board and make some decisions based on the data.

I am not an expert in Python, but I coded a simple script to read the sensors using the repository, getting the hsdatalog_cli.py as an example, and using this data as input to the Raspberry Pi board.

The thing is, I can read the sensors only if I start logging (using the start_log method provided by the script hsdatalog_cli.py), and since the log has started, it will generate .dat files. So, every time I run the algorithm inside the Raspberry Pi, new .dat files are generated, and the file sizes depend on how long the board is running the algorithm.

I have tried to get data from the sensors without starting logging, but I have failed.

Is there any way of getting data from the sensors without generating the dat files?

Thanks in advance!

Hello @janco_tianno 

DATALOG2 example is intended to log data and create datasets. As on today, it works only by saving .dat files on a host (Raspberry or PC) or on an SD card so there is no way to visualize data without starting logging.

Hello @janco_tianno 

We added the feature you requested in the upcoming FP-SNS-DATALOG2 v2.2.0. It should be online in 2/3 weeks.

hsdatalog_GUI will have a new flag to disable data saving on the PC/Raspberry. So, there will be the possibility not to save data and have it only live plotted. 

 

Best regards

Hi @SimonePradolini 

That would be awesome!

We could use the data from the sensors to train an AI model and still use the same structure to get real-time data without saving them.

Thanks for the support!
