Has anyone ported TouchGFX to the CoreH743i board (it uses the STM32H743IIT chip)?

[GGowi.1]

I'm trying to make TouchGFX and the touch screen from this kit

https://www.amazon.com/OpenH743I-C-Development-STM32H743IIT6-Microcontroller-XYGStudy/dp/B07VJ32MC3/?fbclid=IwAR1bRvOE7k_TxZOqdmRFrnxOmykbauhh-5T0qpy14sX4ygGIvmJZph-JOtY

work together. They have samples in Keil for STemWin, but I want to use TouchGFX in my research. (I'm a university professor working on something to support STEM education in underserved areas.)

If anyone has TouchGFX working on this board, I'd really appreciate some help getting started. I'm reading through the porting guide, but I figure why reinvent the wheel.

Thanks!

We don't have any support for this board, but i'll help you if you want to do the work yourself :)

Try reading the board bringup guide in support.touchgfx.com to get yourself started.

Hi Martin,

We can do that. I've started reading the bringup guide and will start working on it. We can communicate here for now and when appropriate I'll set up a git repository so we can collaborate. Fortunately for me, I'm on Summer break until August. (I'm a university professor.) Thus, I have plenty of time to work on this.

Hi! Any news on this? I'm trying to write to the screen using the BSP files included in Waveshare examples. Screen works only if I use 1.3.2 H7 FW version. If I migrate to newer FW versions (1.7.0 and 1.8.0), I have no errors during compiling time but screen remains black. Unfortunately, current TouchGFX versions doesn't compile against 1.3.2 H7 FW. Any thoughts on this? Same files, one project is using newer FW and other using older 1.3.2, older FW works as expected (but can't use TouchGFX with it) and newer doesn't show anything on screen. It's the worst of the two worlds :>

Any help on this would be really appreciated. I think would be nice even to ST having examples of TouchGFX using custom boards/boards from other manufacturers on TouchGFX. It would encourage users to use custom boards.

Hi @GGowi.1 

I just came across your Old post about TouchGFX with STM32H743IIT6.

may I know if your project done successful ?

I have been working with this waveshare's H743 board in past.

Presently I'm working on STM32H745 SOM and Samsung Tab3 10.1" 1280X800 TFT. Its a custom designed board.

Hello. INaee.1

When you were using the wave share board , how did you work around the QUADSPI being on the same pins as the touch screen controller. as I am having great trouble trying to resolve this.

Also did you have a loader file for the Quadspi flash?

 

Thank You

Greg.

PS: amazing work on your Samsung display project, very impressive.

Hi @GOmon.1 

I have been using this wave share boards in past but with LCDs with MCU interface (not RGB).

but I worked on STM32H743BIT6 & TouchGFX for one of fellow from other country and developed the starter 1 screen GFX by using TeamViewer . 8)

>>"how did you work around the QUADSPI being on the same pins as the touch screen controller."

The Touch Screen controller interface can be moved to other SPI port , its maximum 10 min job.

>>"Also did you have a loader file for the Quadspi flash?"

I do my own .stldr (External loader file) for any spi port of my H7xx board.

Do share your schematic and the codes here or in private message and I will solve your hurdles.

N.B . I don't port the codes from 1 controller to other but I always start my project from ZERO in MX.

Hi @INaee.1 

currently I am Working with STM32H743BIT6 & TouchGFX  

I am facing issue with screen flickering,

I am using OpenH7XXI-C board with 7inch capacitive LCD(F) display (Working Fine No issue )

But With  10.1inch capacitive LCD(D) display (NOT Working)

If i display any img i am getting flickering screen.

but If i display without any img, only backround boxs with different colours,No flickering is there.

Tried changing LTDC as per datasheet But No use. 

 

Any guidance on this topic is really appriciated :)
