Hi,
Is there a library to read/write files on a USB key connected on the native usb port (using in the same time the usb programming port to power arduino)?
I need a low cost solution to learn to students in only few hours to write data coming from sensors on a storage support (idealy on a USB key instead of a SD card).
Arduino Due + USB stick would be less expensive than an Ethernet Arduino which has a SD-support capability (or Arduino Uno + a shield with SD-support capability) + SD card + USB adapter to get file on the computer.
Any other ideas?
Best regards,
