CLAB-datalogger-receiver

This repo is a reimplementation of the MATLAB datalogger project in python.

This is to prevent some errors occurring during the ERTC (Embedded Real-Time Control) course due MATLAB's serial interface that was not working properly, and also to increase code portability.

WARNING

You NEED to configure the data received structure via the struct_cfg.yaml file.

If it is not found in the folder where the executable is run, it is created based on the templates/struct_cfg_template.yaml.

How-to

This is a runnable package, meaning that it is possible to run

python -m clab_datalogger_receiver

or by launching the run_receiver.bat file.

Notice that the package needs first to be installed.

This can be done by running install_package.bat

On launch, it will connect to the serial port, (asking which one, if multiple are available), and send the START_TRANSMISSION token to the datalogger.

It is possible to stop the data recording both by pressing CTRL+C or by closing the plot window.

The script will then ask if it should save the data (default is yes).

Packets configuration

It is possible to configure the serial data format in (mainly) two ways:

• By editing the file struct_cfg.yaml, that is loaded by the function call PlottingStruct.from_yaml_file()
• By calling the function PlottingStruct.from_string_list(formats list), where formats is a list of format string that follows the convention of python's struct, as in here
