Thanks for video. Not many that show real life applications using ST’s IDE and GFX

When I go through this process it does work, but I think you might be missing some steps. I am using TouchGFX Designer 4.24.1 and Stm32CubeIDE 1.16.0. However, the file structure in the Project Explorer is not correct. For example, the TouchGFX files inside the 'STM32CubeIDE\Application\User' directory do not have a 'src' and 'include' subdirectories in either the 'gui' or 'generated' directories. The files do exist inside the TouchGFX directory on the file system, but this is not pulled into the Stm32CubeIDE project structure correctly. When I attempt to edit the screen files from the project explorer, there are many compile problems. I attempted to copy the entire TouchGFX directory and go with that, but have even more problems. Also, there is no 'include' or 'src' in the 'Application\User\Core' directory. Where do I find the main.h file in the Project Explorer?

Nice! Thanks! For some MCUs, notably for H7, DO NOT use replace->all, as this would rename important folder-names referenced in the file, which contain the string you are replacing. So you get a lot of broken references. Otherwise, perfect! And kind of rediculous that this procedure is necessary at all...

огонь!

can this be used for STM32H747I - DISCO as well?

Hello, thank you for this tuto but i want to know if it´s possible to interface a SmartEmbedded screen with an toshiba inverter and read out the inverter frequency on the screen by using RS485 wire with Stm32cubeIde and TouchGFX ?

thanx for this beatifuly share

i hope you know how this means to me. Thank you so much.

you saved me man may god bless you

Hello, how did you make the buttons and text background blue? The image assets are grey. Thank you

Hi, thank you very much for your tutorial. Could it be possible to have the source code?

Used this to test Smart Riverdi Display 50STM32U5A9 RS232 - Arduino RS232 shield to expansion port P4-USART1_TX-D1- PG9 -P4-25 AND USART1_RX-D0- PG10 -P4-27 Used TouchGFX v4.23.2, STMCubeMX v6.11.0, X-CUBE-FREERTOS STM32H5/U5/WBA/C0 v1.2.0 and STMCubeIDE v1.5.0 The code had to be updated to use "cmsis_os2.h" and of course all the other STM update improvements? Works with some work! The basic Path “Simple” explanation of what it takes to use TouchGFX is good best I have seen so far.

Hi, great video, by the way, in TouchGFX Designer, there are 3 buttons. Generate code, build (window pops up to test) and build & run. When you finish designing, you just need to click the build & run, and the code is automatically flashed to the board. No need for this complicated stuff. If I understanded this right, this is the same you did. Regards.

Hello. I would like to ask a question. How is that LCD fixed to the pcb? I checked the PCB file provided by STM, but I have no idea how it is fixed. I would appreciate it if you could tell me in detail how it is fixed to the PCB.

Hey, in terms of osSemaphoreRelease(...Handle) function, I understand that this functionality lock/unlock code access of the exectuted thread so that other threads do not have a potential acess to the updating value (of the ADC in this case). So this works like mutexes in terms of lock/unlock for pthread_create() in RTOS, am I understanding the use of osSemaphoreRelease in this sense, correctly?

Hello carl, xSemaphoreGive function not avalible in cmsis_os2. What can i do about it

Dear Mr. Karl First of all, congratulations for you tutorial and to share with us. Dear Karl in my project if I enable freeRTOS, the programs stops working and the display turn off.How can I send data from touchGFX (GUI) to main task (MCU) wthouy freeertos.Could you please send an example. Thanks best regards.

please help, i want to go back to the factory condition on this board. After i debug it with stm32cube i can only see a white screen. I used a binary factory but the touch screen not responsive ther was a game in factory condition and now nothing work. Please help

Can you send all the link such as the library please

Hi Karl, I am using STM32F469I-DISCO (DK32F469I$AU1), TouchGFX is version 4.21.1. My app is just a box with a button on it. Code generation and flashing onto the board show no error in TouchGFX, so is building app in STM32CubeIDE (with firmware version FW_F4 V1.27.1) but it just gives blank screen. Tried a few examples and demos on the board too, none worked. I have another made in China board, i can created TouchGFX app and runs fine, but this STMF469I-DISCO just drives me nuts, just could not get it run even a simple app. Any clue ?

Hi i am getting error like this when i debug the project....Drivers/BSP/STM32746G-Discovery/stm32746g_discovery_sd.c:459:35: error: unknown type name 'SD_HandleTypeDef'; did you mean 'TIM_HandleTypeDef'? can you please help me with this

Leave some comments if you found this tutorial helpful and what you use the timercallback for

Great tutorial Karl!!! It got me started on my discovery board real fast, thank you!!!

excuse me, for this video how to make long press button using timer ? thank you

Hi, thanks for sharing touchGFX tutorial , I am new to touchgfx, and trying to display float value on TextArea , using following code is working w/o problem. Unicode::snprintf(textArea2Buffer, TEXTAREA1_SIZE, "%d", gTvalue); textArea2.invalidate(); But if I change with floating Unicode::snprintf(textArea4Buffer, TEXTAREA4_SIZE, "%3.1f", gTvalue); I get text -- %3.1f is there anything setting I missing? please advics, thank you.

Wow, thank you! Been struggling with this for a long time and you solved it for me! 🙏 ST's documentation leaves a bit to be desired.

I ran across a note in the STM community "rename STM32CubeIDE project". It seems the process is much simplified. All that needs be done is to open the .project file and on the first line correct the default name supplied by touchgfx designer (which is the board name). Then when importing the project into the STM32Cube-IDE it will be named appropriately AND there won't be a conflict with the board name attached to the ioc file.

thank u so much!! :D

hello sir,touch not working in stm32 after reset,how i can solve this issue ?

The very first operation is to select something from TouchGFX Designer -- how is that installed?

Thx Karl ! It works good. I am using TouchGFX 4.20.0 and STM32CubeIDE 1.10.1. But ioc file doesnt create or linked. So i added link code to .project file then when i created project, it linked a ioc file.

Hello, I like your STM videos! May you eventually do an updated one where you install some GFX example? Thanks

Has anybody an idea on how to implement hw button control for the keygoard? I am currently stuck on integrating it on a non touch screen.

Thanks Karl!!!

Can you Debuging with VSCode? Can you MAKE A VIDEO 😊

Nice video.I followed your video for stm32f469i disco but it doesn't work.I tried many times but the screen remain black.can you make a video for stm32f469i disco.thanks in advance

stm32F429 ?? stm32F469?

The video is titled STM32F469I-DISCO but you go on to do everything on a STM32F429I-DISCO. Is this on purpose and the advise universal for the DISCO boards or an error?

Great have you back.

Waiting for feature videos on touchgfx

Good video sir

I am using the STM32F429I In some of the files that you have modified, in addition to having 'STM32F429I-DISCO' I also have the following: "STM32F429I_DISCO_REV_E01" Should I replace this as well?

I cannot see the .ioc file generated when I import THE existing project into Workspace (as you did at 4:37)

"You have a bad pixel on your screen" 🤣😂

Good day, great video, Does anybody knows why the .ioc file is not imported? is there some procedure during installation of STM cube ide or touchGFX ?

I compiled the github project with errors such as /Middlewares/ST/touchgfx_backup/framework/source/platform/hal/simulator/sdl2/HALSDL2.cpp:18:10: fatal error: SDL2/SDL.h: No such file or directory. Please advise

For me, it only worked when I copied also "TouchGFXJAL.hpp and TouchGFXJAL.cpp"

Is it same process on STM32F469I-DISCO Board...Can i follow that steps on my DISCO board. please reply me...If any video you have then link send me please...

The great shepherd has given me a great deal. Thank you. Biji Karl in the Kurdish language

when you are post the next parts, i waiting for thats one
