I have been having fun with the m5Cardputer, but am trying to create an INI file for Config settings.

I want to use the mINI file class by metaYeti:

https://github.com/metayeti/mINI

So I've started with this code:

  mINI::INIFile file("myfile.ini");
  mINI::INIStructure ini;
  //file.read(ini);
   ini["section"]["key"] = "value adj"; 
   file.generate(ini);
   Serial.printf ("Ini section is %s\n",ini.get("section").get("key").c_str());
  //file.write(ini); 
  Serial.printf ("Tried to write INI to SD card.\n");

This all compiles and runs - but of course, it doesn't do anything. What baffles me is where the INI file would be created - as there is no path or filesystem set in the example above. I have a feeling I need to do something with a filestream class or something - and somehow make this stream connect with the SD filesystem object or something.

The object is clearly being created - because I can print out the value I set (as shown above).

So can anyone tell me how this can be actually linked to an actual inifile stored in an actual folder!?!

Thanks!
