How to use with SD card

Hi, I have a file on my SD card "config.txt" that I would like to read from (not using the local filesystem as in your example).

I can't work out what to change in the example to read from the SD card instead of the local filesystem.

Can anyone provide some guidance please?

Short version: Change

LocalFileSystem local("local");


SDFileSystem sdCard(SD_MOSI , SD_MISO , SD_CLK , SD_nCS , "local");

where SD_MOSI, SD_MISO, SD_CLK & SD_nCS are the pins used for those signals on your board.

Hi, this helped me. I was already using the SD card but couldn't work out how to integrate the ConfigFile with what I was already doing. I ended up changing the word 'local' with 'sd' as I am using in my SDFileSystem command. Thank you.
