MICROSD CARD

schakoma — Fri, 14 Jan 2022 01:57:31 GMT

Hello.

I would like to interface a microsd card with the CLEV6630B or LPCXpresso845MAX evaluation boards to read and write data to the microSD card. I am still new to the arm microcontrollers and I would appreciate some demo code to start with.

Thank you.

I would suggest to start with an appropriate example from the SDK for your boards. SD card or FatFS examples should be appropriate.

I don't know both of your boards myself. But with an external SD card interface, there is likely some code to adapt, or to port. The lowest layer of this SD card /FatFS code is target specific. This is quite some task for a beginner.

The easiest route would be a board that comes with an SD card interface and slot, like my OM13098. The SDK example code for those usually works out of the box.
