STM32 NAND driver blocks
This document describes how to connect a NAND Flash device to an STM32 family
microcontroller and communicate using FSMC. NAND driver library for STM32 is a generic
library where STM32 can access NAND with some advanced features like garbage
collection, wear leveling, bad block management, ECC checking etc. The library supports
both FAT file system and USB MSC device.

STM32 USB peripheral
The STM32F embeds a USB peripheral that supports USB full-speed and high speed.
The development of Endpoint and support suspend / resume are configured by software.
The USB device provides a connection between the host and the function implemented by
the microcontroller.
Data transfer between the host and the memory system is through a dedicated packet buffer
memory accessed directly from the USB device. The size of buffer memory is dependent on
the number of endpoints used and the maximum packet size. This dedicated memory is 512
bytes.
