TouchGFX- STM32F423ZHT6

Marudhupandian · ‎2024-09-01

Hi,

STM32CubeIDE- 1.13.2

TouchGFX - 4.24.0

STM32F423ZHT6 evaluation board has lack of LTDC and DMA2D compare to other STM32F4 series. I want to turn on the LCD panel (NHD-2.8-240320AF-CSXP-FCTP-ND) and it display the white background. Can any one please guide me? How to do it.

I recommend following our guide : board-introduction .

Here is the part where we control the screen and test it : display-internal

Regards,

Gaetan Godart
Software engineer at ST (TouchGFX)

Okay. Thanks for your reply @GaetanGodart

Marudhupandian · ‎2024-09-03

I stuck in LCD interface. In my MCU (STM32F423ZHT6) doesn't have LTDC and DMA2D. How can I interface with LCD display? If any other method to interface with my LCD panel and MCU. Let me know.

Can I implement the SPI interface for LCD.

I have old project (Smart lock) without touchGFX designer. Here, they using LCD touch for Number pad. But the problem is there is no specific .ioc file. They use ST7789h2 driver.

So, I want implement a effective GUI application by using TouchGFX.

Hi @GaetanGodart

Today I create a project on STM32F412- Disco. It generate the Makefile can I edit it for my STM32F413ZH board.

If it is possible mans can you help me.

Hello @Marudhupandian ,

You have to check what the communication protocol is for your screen.
There is a lot of cheaper screens that use SPI.
We also use SPI on the STM32G071RB nucleo + GFX01M2 so you could create a new project from TouchGFX Designer to see how we used SPI there.
Otherwise, you can also look at some YouTube guides, you will most likely find a guide for your screen as ST7789h2 is a pretty common display.
I have looked and it seems you can use FMC to control it which is totally fine.

Regarding the Makefile, you should update the names from 412 to 413, check for compiler options and the linker script.

You can try this one :

# Helper macros to convert spaces into question marks and back again
e :=
sp := $(e) $(e)
qs = $(subst ?,$(sp),$1)
sq = $(subst $(sp),?,$1)

# Get name of this Makefile (avoid getting word 0 and a starting space)
makefile_name := $(wordlist 1,1000,$(MAKEFILE_LIST))

# Get path of this Makefile
makefile_path := $(call qs,$(dir $(call sq,$(abspath $(call sq,$(makefile_name))))))

# Get path where the Application is
application_path := $(call qs,$(abspath $(call sq,$(makefile_path)..)))

# Change makefile_name to a relative path
makefile_name := $(subst $(call sq,$(application_path))/,,$(call sq,$(abspath $(call sq,$(makefile_name)))))

# Get relative path to makefile from application_path
makefile_path_relative := $(subst $(call sq,$(application_path))/,,$(call sq,$(abspath $(call sq,$(makefile_path)))))

# Get path to Middlewares
touchgfx_middlewares_path := gcc/Middlewares
cubemx_middlewares_path := Middlewares

# Get path to Drivers
Drivers_path := Drivers

# Get OS path
touchgfx_os_path := $(touchgfx_middlewares_path)/Third_Party/FreeRTOS
