Hello @khanhcong861989 ,

A blinky example and using a screen are not the same level of difficulty.
You will have to read a lot of documentation and try a few different things before it works I guess.

That being said, let me help you the best I can.

If you want to use TouchGFX to create a GUI, please, start by reading our documentation and more specificaly, you should read the board bring up guide .
Once you correctly setup your board, you can try to fill the screen to red : display framebuffer .

If you do not want to use TouchGFX, then you should just use your screen's library.
To do so, look at resources online, there is plenty of various quality :

3. https://github.com/timagr615/TFT_ILI9488

Overall, if you want me to help you, you should prove more information about your project:

1. what board do you use
2. what is the screen exactly
3. what library do you you
4. what software do you use (with versions)
5. what guide did you follow
6. what have you tried to do
7. what is the issue
8. what did you try to solve the issue
9. anything else that you think is important to share

I hope this helps! :smiling_face_with_smiling_eyes:

Dear!

my issue wasn't fixed yet, bro. i still try my best to display the screen

Hello @khanhcong861989 ,

Are you blocked at something specific?

Otherwise, you should first try to control your display before enabling TouchGFX because TouchGFX's job is to render the UI to a framebuffer and store it in memory, then TouchGFX sends the framebuffer to the display. It is more likely that the rendering will work fine, but it might not work to send the rendered data to the memory or to send the data to the display, so you should test those 2 separately.
You should try to just et your screen to a solid color by using the functions provided for it (such as FMC_fill_Screen or whatever).

Maybe have a look at some YouTube videos if you are stuck :
 - How to set up TouchGFX with SPI Displays || ILI9341 
 - A fast TouchGFX library for ILI9341, ILI9488 and ST7735 on STM32 
 - How to integrate TouchGFX in a custom board (The long way round)
