SD card Tutorial for the unitiated

Page last updated 14 Jan 2014, by Alexander Lang. 1 reply

I struggled to get the SD card example to work easily and quickly so I'm in the process of writing up a tutorial.

I'm hopefully adding to the information in the SD card file system page - https://mbed.org/cookbook/SD-Card-File-System

Here is the schematic:

Here is a photo of my wiring:

Hi Alex, I know it's an old post, but I'm struggling to make my project work: https://os.mbed.com/users/ffxx68/code/SDFileSystem_HelloWorld/ using an SD card with a Nucleo-LR053R8 board. I noticed you had similar problems, apparently with the board power (from the blog post). How you realized the reason and fixed it? I'm powering my board trhough the USB and Vcc on the sd card adapter reads about 3.15V. What values should I expect? Thanks - Fabio
