ok let's say I actually want to store the trip computer's configuration in a SPIFFS file using a syntax like
appearance.screenBrightness=230;
appearance.soundOn=true;
How do I go about doing that, in a roundabout way?
As I said, I'm somewhat familiar with file access functions, but haven't done anything like this in C or even C++. The kind of php coding I did with plain text files mainly involved analyzing server logs or other flatfile data with the use of php.
