SD.begin() returns false no matter what

[amsquid]

I am using an Arduino Mega 2560 with a Treedix 3.5" TFT shield. I put an SD card (Formatted to FAT32) in it and attempted to use "SD.begin(10)", but it's returning false. I have both the SD.h and SPI.h included. I've scoured the internet and have not found any working solution, thanks!

Welcome!
You can try

if (!SD.begin(10, 11, 12, 13)) {
    Serial.println("Card failed, or not present");
  }

And let me know how that goes.
Can you post a link to the exact screen you have?

Also please post your code.

if (!SD.begin(10, 11, 12, 13)) {
    Serial.println("Card failed, or not present");

SD code is in the boot method.

It's bringing up this error, "no matching function for call to 'SDLib::SDClass::begin(int, int, int, int)'"

That's the old code, I copied and pasted your code and it brought that error.

[outbackhut]

@amsquid
Can you post a link to the exact screen you have please?
Where did you get that SD library? Was it downloaded from the library manager, or elsewhere?

[amsquid]

It is just the default SD library built into Arduino IDE.
If by the screen you mean what shows on the TFT, it just shows the error messages I put into the if statement.
"SD reading failed"
"Resetting in 5 seconds..."

Here is an image of it...

[outbackhut]

@amsquid
No. I mean the ebay link or whatever store you got it at. I need a screen datasheet, or at least a model number.

If it was the default SD library it would not say:

@amsquid

"no matching function for call to 'SDLib::SDClass::begin(int, int, int, int)'"

Can you tell me who wrote the library (op[en the library manager and see what the authors name is)?

Is it this one:

SD - Arduino Reference

[jfjlaros]

@amsquid

SD.begin(10)

Did you use pins 50, 51 and 52?

SD - begin() - Arduino Reference

This begins use of the SPI bus (digital pins 11, 12, and 13 on most Arduino boards; 50, 51, and 52 on the Mega) and the chip select pin, which defaults to the hardware SS pin (pin 10 on most Arduino boards, 53 on the Mega). Note that even if you use a different chip select pin, the hardware SS pin must be kept as an output or the SD library functions will not work.

[outbackhut]

@jfjlaros

@jfjlaros

Did you use pins 50, 51 and 52?

You don't have to. Mine works well on the Uno pins, even though I'm using it on a Mega.

[amsquid]

Here's the WIKI that was linked with the TFT: 3.5inch Arduino Display-UNO - LCD wiki.
Here's the amazon page: https://www.amazon.com/dp/B0872S57HG

The author line says the following: Built-In by Arduino Version 1.2.4 INSTALLED

[amsquid]

I checked the SD_SS pin (CS pin according to LCD Wiki) and unless I'm mistaken, it is on pin 10.

Please test it. It compiles perfectly for me, so if you have the same library, it will work for you.

[amsquid]

Doesn't work. Are you using a different version or library?

[outbackhut]

What version do you have?

[amsquid]

Version 1.2.4

[outbackhut]

Are you sure this is what you have?

If it is , please downgrade it (select an old version and install it) and then update it again.

[amsquid]

Still doesn't seem to work. By the looks of it, you're on windows. I'm on mac but I can try to compile on windows, I doubt that would change but I'll give it a shot.

[outbackhut]

Yes, I am on windows.

You have the wrong library. There is no such thing as a src folder in the library I am using.
