Is the SDHC interface supported for FRDM-K64F

Hi,

While I know that you can use SPI to access the SD card, has any work been done to enable using the SDHC interface built into the MCU? I'm assuming that using the built interface would be quicker and require less over head.

Thanks

Robin

The current implementation uses SPI. It would be a nice addition to swap SPI and SDHC and use where available. Give this a try if up for the challenge :D and reach out if you have questions along the way!!

Accepted Answer

Did anything come of this, will the sdhc interface be something that will become supported in the future?

Thanks.

I'm not sure this is something we'll do but if you implement a BlockDevice for this is should be quite straight forward. Here are the docs on the BlockDevice API https://os.mbed.com/docs/v5.6/reference/contributing-storage.html#block-devices
