I may have gotten over my head here. I need to know how to create a txt file and read and write to in on a usb flash drive using the Arduino mega 2560 and the usb host shield found on the Arduino store: Accessories — Arduino Official Store.
I thought it would be as simple as using the sd counterpart, but no one uses the usb shields in this manner.
Please help. I just need to know the basic code functions to help me get going.
