Check if SD is connected

Postby raphaelbs » Tue Jan 01, 2019 1:51 pm

Hi, happy new year!

I'm using SD in FatFS mode and while building my application lifecycle I need to handle SD disconnections.

Is it possible?

And a Happy New Year to you too.

If the SD card reader has a CD (Card Detect) output it could be connected to an ESP32 GPIO to detect whether or not a card is present.
