LPC1788: best SDCard driver

giusloq — Fri, 19 Mar 2021 12:12:51 GMT

I'm going to add SDCard support to my application that will run on LPC1788. I have external SDRAM and the application actually runs emWin (I don't know if this is important).

I know there is LPCOpen demo projects for LPC1788, but they are very old (2014!!). Is there any recent SDcard driver available for LPC1788? Should I use LPCOpen driver?

In the forum I found another driver here, dated back 2015.

Any suggestions?

LPC1788 is old product of 8 or 9 years ago. Now NXP only has LPCOpen demo for it.

As I know there is no plan to release new sdcard demo for it.

Have a nice day,

@giusloq ,

I have the mmci driver running you refer to (the one in a rar file) in the posts. I gave up on NXP's original MMCI driver a long time ago. The one by "Wolfgang Muees" in the file "auerswald_lpc178x_mci.tar.gz" has been working here for some years (the code is actually from 2011.

Hope it can help you in some way!

Regards,

Carsten
