Hi!

I want to use the FRDM-K64F to read and write .txt files and .wav files from mcu to sd card using only the 4-bit mode.

Is this possible? Anyone has any material to study/investigate?

Thanks

Hi

See http://www.utasker.com/kinetis/FRDM-K64F.html

Here you can try SD card operation on the FRDM-K64F together with USB-MSD operation to the SD card, use the SD card as file system for an FTP/ web server or read/write files on its DOS like interface (via UART or Telnet).

The complete operation can be simulated in (approx.) real-time in VisualStudio on a virtual K64.

Details of the file system and SD card interface, including low level developer functions to test the SD card and perform things link analysis of short or long name files, and deleted file, or undeleting are at http://www.utasker.com/docs/uTasker/uTasker_utFAT.PDF

Regards

Mark
