SD card working but with other sketch I get a warning

Other Hardware Storage
1

I have a Wemos D1 R1
I can write on the SD and also read the SD
When I use the sample sketch and use the same conditions I get a lot of warning like: SD2Card does not name a type.
Can someone tell me what is going wrong?
Thanks

Post your code
Use code tags </>

Then, post your warnings too, use the copy button from the IDE

it seems not a warning, it must be a error

Hi
Here is the code.

/*
  SD card test

 This example shows how use the utility libraries on which the'
 SD library is based in order to get info about your SD card.
 Very useful for testing a card when you're not sure whether its working or not.

 The circuit:
  * SD card attached to SPI bus as follows:
 ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
 ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
 ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
 ** CS - depends on your SD card shield or module.
 		Pin 4 used here for consistency with other Arduino examples

you forget to comment right bracket in this fragment:

Hi
I comment, but the warning remains.

Please copy to the forum all compiler diagnostic output

Try

#include "utility/SD2Card.h"

Hi,
researching your problem I identified a possibility:

There is an SD lib for Arduino and an SD lib for ESP8266.

On my PC the lib for the arduino is in the folder:
C:\Program Files (x86)\Arduino\libraries
and the lib for ESP8266 is in the folder:
C:\Users\xxxxx\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.6.3\libraries

This example you are using compiles well with Arduino.
But if you look at the ESP8266 example folder it is not there.

So I believe it's a sketch just for arduinos.

Thanks. I'm trying this file.

I'm not at home. I send it as quick as possible.

Hi,

You’re right.
