求SD卡的开发文档

[zhangeh10594]

最近在做基于LPC55S69的SD卡扩展，但是完全不知道怎么入手啊，由于LPC55S69又是一个比较新的单片机，所以也没找到相关的SD卡开发程序，请问大家有相关的资源吗？诚心求教怎么写SD卡的程序，还有，sdk的开发例程，可以用来参考写自己的SD卡程序吗？谢谢大家了！1

Hi 小白 张 

There is SD card demo code under LPC55s69 SDK.

you need download 55s69 SDK from this url

Welcome | MCUXpresso SDK Builder 

Then  find demo code code from this path:

{LPCXpresso55S69 SDK folder}\boards\lpcxpresso55s69\driver_examples\sdcard

there is readme.txt under the project folder which tells how to use the demo code.

Have a great day,
Jun Zhang
