SDHC kinetis for FAT

xavierbuhot — Tue, 17 Nov 2015 13:14:22 GMT

Hello,

I am looking fot SDHC library for my kinetis k60.

I use IAR and I would like to be able to write information on SD card.

Is there any SDHC library already develop?

Best regard.

If you're using MQX the MFS library works well. I've used it on multiple boards for reading USB and SDHC filesystems. Otherwise, under the KSDK there is also the FatFS drivers. I haven't used them myself, but they should work for your purpose.

Hi Xavier

You can also try utFAT - http://www.utasker.com/docs/uTasker/uTasker_utFAT.PDF

This has more features that FatFS, including data caching between shared files, file analysis functions, undelete, as well as FAT emulation - http://www.utasker.com/docs/uTasker/uTaskerEmulatedFAT.pdf

Works with all Kinetis parts (with SPI or SDHC) and all common IDEs (IAR, Keil, KDS, CW, Atollic, Green Hills, Rowley, CooCox, etc.) and allows SDHC/SD card simulation in VisualStudio.

Supports multiple disks (SD card, Memory Sticks, multiple USB-MSD LUMs).

Regards

Mark

Hello Xavier:

Those are good suggestions by Luciano and Mark. For the case of KSDK, you can find a document about using the SDHC driver in the next link:

FatFs + SDHC data logger with KSDK in Kinetis Design Studio

Sorry for the late response. Thank you everyone for the answer.

I am studying all the data you gave me.

In fact I am looking for drivers on IAR without ROS.

I will try to get a ROS free drivers.
