How can I get start with the SDK from the authors,I even can't understand the code,so please tell me how can I read a series of codes,like the sdcard_polling and sdcard_interrupt.
In others words,how can I write the SDcard's code.
Please check the following link, this describes the SD driver,
MCUXpresso SDK API Reference Manual: Secure Digital Card/Embedded MultiMedia Card (CARD)
In addition, I suggest download the SDK documentation in order to check the API references.
I hope this helps, have a nice day!
