FAT16 and FAT32 - DOSonCHIP interfacing

[freeskier89]

Hello there,

I just purchased a FAT16 and FAT32 - DOSonCHIP IC and I just had a look at the datasheet. It seems to contain very little information on the commands needed to use it. It give the electrical specs and even typical configurations, but no commands for writing/reading files.

Does anyone have any experience with them? The datasheet seems to be worthless. Should I just contact the company that makes them?

Thanks

The [user guide describes the command interface.](http://chipdos.com/library/CD17B10_User_Guide_0v1.pdf)

Thanks a lot! I really really quickly skimmed over the user guide before, but did not see the commands because it had wierd formatting compared to other datasheets. Thanks for pointing me back to it

Does anyone know if this handles LongFileNames? What about data transfer rates?
