STM32 MCUs TouchGFX and GUI

Hello!I need to be able to enable and disable touch screen from my GUI application. I don't want to cut the power to the touchscreen.I want my handle click functions on multiple screens to not to respond to touch events for some time after certain point of time or another event. So I imagine a function in Model class that would somehow enable and disable touch events. How can I achieve that the best way?I guess it is not a good idea to have a flag in touchController (if the flag is set, return false from sampleTouch...)Thank you.

In TouchGFX(4.22.0)，I want to implement a curve similar to the following imageActually it is an SVG image, is it possible to change its path and gradient color using a program in TouchGFX? What I mean is not using ‘SVG Image’, but simply using a programmatic approach(the path may not be so complicated).  <?xml version="1.0" encoding="utf-8"?> <!-- Generator: Adobe Illustrator 23.1.0, SVG Export Plug-In .

I want the user to hold a button for at least 3 seconds before it triggers its interaction. So I created a Repeat Button, because the documentation says on delay: "Delay specifies the time (ms) to wait when the button is pressed before starting the loop of triggers."But when I configure a delay of e.g. 2000 ms and an interval time of 8000 ms, it triggers immediately and then after 2 seconds (and then every 8 seconds). Is this misleading in the documentation or a wrong behavior of the button?

My HW is NUCLEO-F446RE and X-NUCLEO-GFX01M1.TouchGFX is configured in partial frame buffer (3x1920 bytes)In the project I use FreeRTOS API CMSIS V2.The assert in question occurs randomly:assertion "state[nextSendingBlock] == DRAWN" failed: file "../Middlewares/ST/touchgfx/framework/include/touchgfx/hal/FrameBufferAllocator.hpp", line 241, function: const touchgfx::Rect& touchgfx::ManyBlockAllocator<block_size, blocks, bytes_pr_pixel>::peekBlockForTransfer() [with long unsigned int block_size = 1920; long unsigned int blocks = 3; long unsigned int bytes_pr_pixel = 2]When the assert occurs, the state fields are all EMPTY.

I am looking to implement back button to go back to previous screen (similar to UI on a smart phone). For this,1. Need to remember current screen before a button is pressed.2. In the new screen, when a back button is pressed, programmatically change to previous screen. It would need a common memory area where current screen can be saved. This information should be accessible from any screen so that it can be read when a back button on that particular screen is pressed. Here is a scenario:There is title bar with a button, say Button1.Screen 1 leads to Screen 2. Screen 2 leads to Screen 3. All screens have title bar with same Button1.Two ways to reach screen 3. First, by clicking the Button1 on title bar (a short cut). Second, Screen1 to Screen 2 to Screen3.Screen3 has a back button.When present screen is Screen1 and Screen3 is reached by pressing the Button1, if a back button is pressed in Screen3 then Screen1 should be reached.When transition is Screen1 to Screen2 to Screen3, if a

Hello,Can someone at ST provide explicit, step-by-step instructions describing in detail how to generate a project for the STM32H755 with TouchGFX running on the CM7 processor? All the posts I've seen online seem to describe ways of hacking projects together involving copying, editing, copying .cproject files, moving TouchGFX files around, deleting simulation files, etc. I've spent days on this now and always seems to end up with a project that can't build because the tools can't find TouchGFX files because TouchGFX generated those files in the wrong place (according to where CubeIDE thought they should be). My board has a working SDRAM, working LTDC correctly displaying whatever I write to the frame buffer in the SDRAM, etc. I have regenerated this project countless times now but always end up in the same place.1. What tool should I be starting my project with? CubeIDE? CubeMX? TouchGFX?2. What should the project structure look like when configured properly? What does the project dire

Hi,For TrustZone enabled project (U5), TouchGFX configuration in CubeMX can't recognize enabled THREADX.Any ideas?Two screenshots attached:one for TrustZone enabled project setup and another one for the exact same but Non-TrustZone project.For the former it can be seen that THREADX option is greyed-out and cannot be selected, while for latter everything highlighted as expected.CubeMX generates correct project for non-TrustZone enabled project.TouchGFX version is 23.1, CubeMX is 6.10.0Thanks   

I have been struggling for a few days now with trying to trigger an interaction within TouchGFX (V4.23.1) via a hardware button.The board is a STM32H747i Discovery. The board bring up has been completed with a standard TouchGFX template and the touch screen and display are working fine.I have verified that I can toggle LED4 with the wake button suing a RTOS function   #define LED4_GPIO_Port GPIOI #define LED4_Pin GPIO_PIN_15 ... /* USER CODE BEGIN RTOS_THREADS */ osThreadId_t toggleLEDTaskHandle; const osThreadAttr_t toggleLEDTask_attributes = { .name = "toggleLEDTask", .stack_size = 128 * 4, // Adjust stack size as needed .priority = (osPriority_t) osPriorityNormal, }; toggleLEDTaskHandle = osThreadNew(ToggleLEDTask, NULL, &toggleLEDTask_attributes); /* USER CODE END RTOS_THREADS */ ... /* USER CODE BEGIN 4 */ void ToggleLEDTask(void *argument) { uint8_t ledState = 0; // Track LED state, 0 = off, 1 = on for(;;) { if(HAL_GPIO_ReadPin(BTN_USER_G

hi,i am working on the STM32L and i have a problem with the lcd, no matter wich programm i am testing it's not working the programm hangs in the function LCD_Init() at : /*!< Wait Until the LCD Booster is ready */  while(LCD_GetFlagStatus(LCD_FLAG_RDY) == RESET)i tried to reboot the stm32l but still not workingis there something i can do to fix it ? or is it out of use ?

When I set up contrast to value less than 5 I get stuck on HAL_LCD_Init() on wait for booster, and initialization fails: /*!< Wait Until the LCD Booster is ready */ while(__HAL_LCD_GET_FLAG(hlcd, LCD_FLAG_RDY) == RESET) { if((HAL_GetTick() - tickstart ) > LCD_TIMEOUT_VALUE) { hlcd->ErrorCode = HAL_LCD_ERROR_RDY; return HAL_TIMEOUT; } }Do I have to initilize something else to get other values of contrast? hlcd.Instance = LCD; hlcd.Init.Prescaler = LCD_PRESCALER_1; hlcd.Init.Divider = LCD_DIVIDER_31; hlcd.Init.Duty = LCD_DUTY_1_4; hlcd.Init.Bias = LCD_BIAS_1_3; hlcd.Init.VoltageSource = LCD_VOLTAGESOURCE_INTERNAL; hlcd.Init.Contrast = LCD_CONTRASTLEVEL_5; hlcd.Init.DeadTime = LCD_DEADTIME_0; hlcd.Init.PulseOnDuration = LCD_PULSEONDURATION_4; hlcd.Init.HighDrive = LCD_HIGHDRIVE_0; hlcd.Init.BlinkMode = LCD_BLINKMODE_OFF; hlcd.Init.BlinkFrequency = LCD_BLINKFREQUENCY_DIV8; hlcd.Init.MuxSegment = LCD_MUXSEGMENT_DISABLE;

I'm playing around with the STM32U5A9J-DK dev kit and looking at the built in demo. Was the UI created using TouchGFX?

Hello,I'm starting a project with an STM32F429IIT6 MCU, but I have a doubt. The project will have a display (I haven't decided yet if it will be 4.3" or 7"), and I'll be controlling the display with the MCU's internal TFT controller using TouchGFX. So far, so good. The issue is that the device needs to be able to capture a screenshot of the screen and save it to an internal microSD. Is this possible, or should I use an external driver to achieve this?Best Regards,

Hi, I have TouchGFX Designer 4.22.0 version installed in my PC. For my project I am using STM32U5A9NJH6Q  controller with Riverdi display part number SM-RVT50HQSNWC00-B. But, in the TouchGFX Designer application I am not able to create a project because in create->By Partners i am not able to find a template for this particular display. I can only find the templae for 1280*800 and 1024*600 resolution displays for Riverdi. But not for 800*480 resolution.  Can any one please have a look in this and help me fix this issue. I have also attached in the screenshot of how my designer application create window looks.

 Hi, I'm working on STM32F746G-DISCO. Kindly can someone tell me if it is normal that after making some project screens on TouchGFX and launching the SIMULATOR, everything is ok. I open the project with CubeIde and add some code from the IDE and transfer it to STM32F746G-DISCO it continues to work, if I try to simulate it with the TouchGFX SIMULATOR I can no longer make it work and it gives me errors right in the lines of code I have added. Thank you.

since i Updated to TouchGFX 4.21.0 (from 4.20.0) the LCD shows a visual artifactit happens when rendering images in the L8_565 format (plain RBG_565 works) or texti'm using a STM32 nucleo board with a STM32H7A3 processorwhen i generated the code with CubeMX 6.6.1 and TouchGFX 4.20.0 it worked without artifactsbut after i updated to CubeMX 6.7.0 and TouchGFX 4.21.0 it started showing these artifacts:example 1: this full screen image should have a solid yellow background, it is revealed using a wipe transition from black to the image. The wipe transition leaves black artifacts on the right edge (transition goes from left to right) Example 2: the text on the last menu tile is sometimes cut in half, it should say "Sprache" -Clemens

I am working on STM32H750B-DK and created a project using TouchGFX Designer (version 4.23.0), flash the code using Touchgfx Designer, and it's working well. but I will import the same project in STM32CubeIDE (version 1.14.1) , while executing Debugging mode the Display is hanging. the program breaks at the below function in the syscall. my project has multiple screens. the first screen is successfully teardown but the time of change screen to the next screen is the problem happens Please suggest any solutions    void _exit (int status) { _kill(status, -1); while (1) {} /* Make sure we hang here */ }     

Hello,We are in the process of integrating TouchGFX into our workflow and back-end build systems. We are using a STM32U599. Please see my question with respect to the tree belowWhat is the difference between TouchGFXNema and NemaGFX libraries?What does the wc16 suffix on the libraries mean? Middlewares/ST/touchgfx_components/ └── gpu2d ├── NemaGFX │ ├── include │ └── lib │ └── core │ └── cortex_m33 │ └── gcc │ ├── libnemagfx.a │ ├── libnemagfx-float-abi-hard.a │ ├── libnemagfx-float-abi-hard-wc16.a │ └── libnemagfx-wc16.a └── TouchGFXNema ├── include │ └── touchgfx_nema └── lib └── cortex_m33 └── gcc ├── libtouchgfxnema.a └── libtouchgfxnema-float-abi-hard.a  

Hello, I am attempting to follow the tutorial listed here in order to generate a simple screen with some widgets for a Riverdi RVT70HSSFWCA0 display board. The board is correctly powered and i can access it with an external ST-LINK.However, when attempting to generate code with TouchGFX Designer (4.23.0) i am getting the following error in class DoubleBufferedVideoController during project compilation: C:/TouchGFXProjects/riverdi7-0001/CM7/TouchGFX/target/generated/TouchGFXGeneratedHAL.cpp:36:70: error: cannot declare variable '{anonymous}::videoController' to be of abstract type 'DoubleBufferedVideoController<1, 800, 480, 2400, touchgfx::Bitmap::RGB888>' 36 | DoubleBufferedVideoController<1, 800, 480, 800 * 3U, Bitmap::RGB888> videoController; | ^~~~~~~~~~~~~~~ In file included from C:/TouchGFXProjects/riverdi7-0001/CM7/TouchGFX/target/generated/TouchGFXGeneratedHAL.cpp:27: ../../../CM7/TouchGFX/target/generated/DoubleBufferedVideoController.hpp:49:7:

Hi,When I close GFX Designer its window disappears, however, the TouchGFXDesigner-4.23.1.exe stays running in the backround - for every opened/closed *.touchgfx project. Does anyone experiences this GFX misbehaviour ?Best regardsFerro

Hi all,we have successully used an external SPI memory to store images.We have defined an external Flash section in our linker file ExtFlashSection :{*(ExtFlashSection ExtFlashSection.*)*(.gnu.linkonce.r.*). = ALIGN(0x4);} >SPI_FLASH and then extract the images from elf file with this command:arm-none-eabi-objcopy.exe --dump-section ExtFlashSection=images.bin Test.elfAll works perfectly.Now we want to store the fonts into the external memory. From the TouchGfx guide we see that we have to add the font section into linker file and thats ok.ExtFlashSection :{*(ExtFlashSection ExtFlashSection.*)*(.gnu.linkonce.r.*). = ALIGN(0x4);} >SPI_FLASHFontFlashSection :{*(FontFlashSection FontFlashSection.*)*(.gnu.linkonce.r.*). = ALIGN(0x4);} >SPI_FLASHNow:should we extract two separate bin files (one for the images and one for the fonts)? And in that case should we merge the bin togheter?arm-none-eabi-objcopy.exe --dump-section ExtFlashSection=images.bin Test.elfarm-none-eabi-ob

Hi there, I'm coming across some issues with respect to Touch GFX and my project. I'm trying to build a UI on the Touch GFX Designer software such that it can display certain temperature readings onto the Riverdi STM32H7 embedded display. I'm trying to use SPI2 communication line from the on-display board MCU to the temperature sensor module and hardware seems to be fine. For the CS Pin I'm using the GPIOA Pin 5 which is used for DAC1 (I've commented out it's initialisation and used it as a Output pin).I was able to successfully build the Touch GFX project and was able to access the 'gui' folder generated by the designer as you can see below: Files Next, I added the files pertaining to the MAX31856 temperature sensor that I'm using and please note that these files are in C and not C++. I also made sure that they were included in the project correctly however I'm not certain. Below are the include paths, the sensor files and the sensor file position in the project explorer:A)

I tried to integrate a working project for version 4.23.0 to 4.23.2 and get the current error as seen in screenshot.I tried to troubleshoot by generating a default project via TGFX to my stm32h7b3I -EVAL board (with a 480x480 screen and GT911 touch driver), and the exact same code gives no errors..... the only real difference lies in STM32TouchController.cpp where I have used the GT911 driver instead of the ft5336 touch controller and I have changed the coordinates to be uint16_t instead of uint32_t.
