I have created two independent programs on the BELA. The first is a system parameter calibration program, that generates parameters associated with our system (for example, amplification level of our loudspeakers, etc).
The second program needs to input these parameters for its functionality.
The programs are in C, created within the BELA IDE.
As mentioned, the programs are completely separate, but most times will run on the same BELA unit.
My question is how can I output the parameters from the first program to a file, and how to read that file in the second program?
What means do I have to create the structures of the data in this “interconnectivity” file?
Writing and Reading to a file
You can use the WriteFile class to write to a text file (see, e.g.: http://docs.bela.io/classWriteFile.html and https://github.com/BelaPlatform/Bela/blob/master/examples/07-DataLogging/logging-sensors/render.cpp ), then I put some code here on how to read from a text file saved as above: https://forum.bela.io/d/719-store-presets-as-file
