I am new to SD card usage on Arduino.
I find reference to SD card utilities but don't know where to get them and any descriptions of them. Can someone guide me here please?
I'm not sure if I understand your problem.
As far as I can remember the SD library comes with the IDE (else you just have to install it). So you can
- Consult the reference pages (Libraries - Arduino Reference) and you will find SD - Arduino Reference
- Study the examples
- Find the library on your system and analyse the header file.
What utilities are you looking for?
The various libraries likely include the basics such as opening, closing, reading & writing a file as well as some directory basics.
I don't have a problem with the SD library. I need to know about the "SD card utilities" as referenced in the examples.
The SD library is quite fine. the commands are clear. For example in the "Card information" example the following is shown:
"Sd2Card card;
SdVolume volume;
SdFile root;"
Where does this come from? There is no reference in the library to these commends?
As far as I can see, you're correct.
They are part of the SD library. Find the library on your system and you will find the files that contain the classes that you're looking for. Understanding them is another story, it will require some digging and knowledge of C++.
