Hi, im trying to read the data from an SD card but i dont think im grasping how to go about it.
I am at the point where my arduino see's the card, finds the text file and opens it all ok, but its the next bit i cant get. The textfile has one line of seperated numbers and i want to load them into varaiables? How do i do this?
Do i first need to load all the file data into a buffer? I cant work out how to read data from the file at a certain point in the file?
Ive done alot of googling but not found alot, theres plenty on getting to the point where i am, and plenty of simply streaming the data to the serial ,but not how to store it?
