Hi all,

Someone can tell me if ST provides USB libraries for high&full speed and file system for FAT16/FAT32 for STM32F20x? I cann't find out these libraries on ST's website.

Thanks in advance

Hello,

1). I'm not familiar with the 20x series but I think, USB device support there should be similar to 10x series. Try

.

2). The file system is mostly supported by tool chain vendors like KEIL (Real View Library, Flash-FS there) or by open source like

Yes you can use free lib FAT_FS-ELM by Chan or EFSL. I have used both the libs for STM32F107VCT6 on IAR and KEIL and they works ok.
