ESP8266 SD Card Interfacing

- This video outlines a few different options for using an SD Card from a Wemos D1 Mini Pro ( or any other ESP8266 device with enough pins. ) I also show how to use a typical Micro SD Card Adapter with no additional components and provide tips and example code to make getting started easier.
I use the SDFat library for working with SD cards on ESP8266 Micro Controllers because the Arduino IDE gives me grief about having multiple "SD" libraries installed. I just find it easier, and functionally the same.
The SDFat library can be found here:

Rewritten / Expanded ESP8266 SDFat Example Code available on Github here: github.com/jgoergen/WemosD1Mi....

great tutorial. thanks!

Hi, I recently made a scrolling text using wemos nodemcu v1 and transmit characters to it via WIFI server.
I want to interface a SD card with it so that whenever there's no new message coming in from the web server, it will automatically read the text content of the sd card then dump it on the display.
The problem is, those HSPI pins was used by the matrix.
Is there a possibility of using the SDIO pins for the card, and do u have any tutorials about that SDIO pins?
Thank you in advance.
Well done! Thank you!

Hi, does the code work for ESP32?
The same idea should work just fine on the ESP32, the pins will probably be different, though. Let me find some time to slap together some code for you and i'll come back and reply with a link!
Took me a while, but here's a video for you!
