This application uses a FatFs middleware module on a STM32F4 Discovery board. The code creates two FAT file systems: one for the on-chip RAM and the other for a USB drive. After a Link Driver phase, the application writes periodically some XYZ values (read from the accelerometer) on the RAM and then, after a USB Drive attach, copy the written values on a new file in the USB drive.
