Seeed Can Bus Shield V2 SD card not initializing

Products & Technology
#1

Hi,

I own a Seed Can Bus shield V2, which Im trying to use on an arduino DUE.

I can’t seem to be able to init the SD card. As per documentation CS should be 4 by default.

I inserted a formatted 32Gb SD card, and called SD.begin(4). This always returns 0 (fail).

What am I doing wrong?

As usual, right after I posted, I found the answer. The Seed SD card slot is a vague one. I inserted the card wrong.

I feel this should be in the manual. As should the correct CS be, more clearly. There should be a section ‘using the SD card’.
