Hello

What is main screen?

/dev/fb0 looks like a Frame Buffer Device.

Frame Buffer Devive and Parallel TFT have completely different resolutions.

If you select the wrong LCD driver, it will not work properly.

I have purchased more than 30 TFTs in the past, but only one correct piece of information.

The information provided by sellers on Ebay or AliExpress is largely incorrect.
You waste time if you don't choose the right driver.
There are many variations of the 2.4 inch shield.

You can use this to find out your driver.
This is for Arduino UNO.

ILI9486 has a different initialization code.

You need to specify the driver as an argument to make.

OS problems can only be solved by the Raspberry Foundation

[nopnop2002]

It may work if you use an old OS.

[nopnop2002]

If so, you have no solution.

[nopnop2002]

Not even others libs insted of this lib?

I do not understand the meaning.

Do you want to use framebuffer

Or do you want to use this library?

This library has nothing to do with the framebuffer.

[nopnop2002]

If you want to use a framebuffer, this library doesn't help at all.

This library doesn't use the framebuffer feature at all.

And I'm not familiar with framebuffers.

[nopnop2002]

The frame buffer is a function of the OS, not a library.

You need to understand what a framebuffer is.

[nopnop2002]

You can find it with the following keywords
