STM32 Tutorial 33 SDcard w FatFS using SDIO

>> YOUR LINK HERE: ___ http://youtube.com/watch?v=S78q6SuwnrM

In this video you will learn how to interface a SD-card with FatFS (ExFAT to be exact) using SDIO. I manage to thoroughly mess it up but figure it out at the end. I have left the mess so you can see - and avoid - the pitfalls yourself - and I actually added the solution the day after the main part was created. • It is a rather long video but it is a slightly complicated subject, so please do bear with me and like the video anyway ;) The video was a result of a request in the comments of an earlier video. • In next video we will repeat this but using SPI for communication with the SD-card.
