STM32 MCUs TouchGFX and GUI

Hi,I want to do a scrolling text. I think, I can use "scrollable container". But how can I scroll automatically don't know.  Is there any example about this type of usage for scrollable container? 

#define CAMERA_FRAME_BUFFER     0xC0260000#define CONVERTED_FRAME_BUFFER 0xC0390000I have seen a example application in the downloaded Bundle from the ST Site. Applications/Camera Example: In this application CAMERA is initialised with CAMERA_FRAME_BUFFER and when Capture the frame with capture command the data is retrieved from CONVERTED_FRAME_BUFFER.I just want to know the logic behind this. Logically the data should be available on CAMERA_FRAME_BUFFER, but why the application is retrieving from CONVERTED_FRAME_BUFFER ?

Hello,I am struggling with Ethernet issue.We see the following:1. stm32h743-EVAL - using RTOS example with udp echo server, stops responds to udp/ping request during a short stress test. And even after stopping the stress, it stops responding at all to any request ! I have to reset board to make is respond (changing to 400 and restarting debugger did not help !!)2. stm32h743-NUCLEO - using RTOS example with udp echo server, still responsds to udp/ping request during a short stress test. Comparing the changes in code (assuming that it is not an HW difference between nucleo and eval), I saw that PLLN in eval was 160, while in nucleo 400. (yet, there are other differences too that I should still check).I suspected that this is the PLLN issue, because when changing PLLN in nucleo to 160, it stops responding during the test. (but after stopping it did continue responding to requests). So, I then tried to change in nucleo to 400, but it did not help in EVAL.Any idea ?Ran

I try to debug a problem with the touch, but I cannot see how FreeRTOS does periodically the functions. See pictures from the call stack. In code the HAL methods are all virtual and I can’t find the code where they are called. It seems there is something hidden in the source ore in my understanding. It would be very helpful to get a description about the concept about the bindings from the graphical lib and the operating system. 

I want to keep track of application so keeping backup in SD CARD with text file.

// Here is my code for when the enter button is clicked: void MainScreenView::EnterButtonClickedFunction() {   Unicode::UnicodeChar STRING = keyboard.getBuffer();   updateWildcard(STRING); targetVacValvePercent.resizeToCurrentText(); targetVacValvePercent.invalidate(); // Close Modal Window targetPercentModalWindow.setVisible(false); targetPercentModalWindow.invalidate(); keyboard.setVisible(false); keyboard.invalidate(); enterValueButton.setVisible(false); closeModalWindowButton.setVisible(false);     }   // Here is my update Wildcard text:   void MainScreenView::updateWildcard(uint16_t text) {   Unicode::snprintf(targetVacValvePercentBuffer, 5, "%d", text); targetVacValvePercent.invalidate(); }

Adding the following includes in Model.cpp prevents the touchgfx simulator from successfully compiling:#include <gui/model/Model.hpp> #include <gui/model/ModelListener.hpp>   extern "C" { #include "main.h" #include "FreeRTOS.h" #include "queue.h" #include "task.h" }I tried adding to the makefile include path as follows, but I think I'm going down a rabbit hole.#keep framework include and source out of this $(build_root_path)../Core/Inc include_paths := $(library_includes) $(foreach comp, $(all_components), $(comp)/include) $(framework_includes) \ C:/Users/webst/STM32CubeIDE/workspace_1.0.1/stm32F769I_disco_cubeide/Core/Inc \ C:/Users/webst/STM32CubeIDE/workspace_1.0.1/stm32F769I_disco_cubeide/Drivers/STM32F7xx_HAL_Driver/Inc \ C:/Users/webst/STM32CubeIDE/workspace_1.0.1/stm32F769I_disco_cubeide/Drivers/CMSIS/Device/ST/STM32F7xx/Include source_paths = $(foreach comp, $(all_components), $(comp)/src) $(framework_source) simulatorThe simulator errors: Compile &nb

I've poured through every doc I could find and only find 2 mentions of interfacing w/ parallel character LCD , 3 if you count the Cube MX drop down menu indicating it can be done. The data sheet clearly indicates it is a thing. The last paragraph of the FMC feature, section 2.8, pg 24 is entirely about this interface Happens to also be the only mention of it. The big book, RM0410, has exactly one bullet point on page 332, again FMC, listing it as a main feature. Not another word. No register mapping, no alternate function pin mapping, no driver/HAL that I can seem to spot... I'm sure it's relatively straight forward, but without basic info, hacking the chip and bit banging my UI isn't really what I was hoping to do for the rest of my life. I just can't find any details, actual information. Any help would be appreciated. Dale

I have an STM32373C Evaluation Board. Recently I downloaded CubeIDE and tried the 'Hello_world' exapmle program and the TFT_LCD works fine. However, I made my own project where I included all the header files which were needed (e.g GUI.h etc..) and in my project all the functions works fine except for LCD related functions. I attached a picture, which shows the error. It is some sort of building error, but I dont know which setting should be used when I build it. Any ideas what is wrong with it?

I can open other projects and simulate fine but I do not see what I could be doing in this project that could make the simulator not work but my target board functions fine.

bool STM32F7TouchController::sampleTouch(int32_t& x, int32_t& y) is working as it can be tested by setting a breakpoint. The display is running as it is tested with an animated image that runs fine.It runs fine in simulator but not on stm32f746G-discovery (Working with STM32CubeIDE 1.1.0) : The display is not reacting on button pressed at all. Any hints to get the touch working with the display are welcome.

I have connected Two cameras ( RGB camera and Lepton Camera) in STM32H743 board i would like to read the camera output. But the cameras are not getting proper voltage . so the initialization process is getting failed . kindly give me the solution..Hello People, I am using STM32H743 Nucleo board and iam connecting two cameras in it. One is RGB camera and another one is Lepton camera . I am using DCMI for RGB and SPI for Lepton camera . I would like to read both the cameras . I am using STLink V2 Programmer to program the board and i have also done High speed USB interface. so iam using ST link programmer and a USB for the power. i have configured the pins correctly . I have set the firmware also perfectly . when i build the code or debug it i am not getting any errors . but i cant able to read the cameras it is showing like initialization process failed for of both the cameras . So when i checked the voltages of the camera board it is not getting enough power supply

I can't understand why a give text with a given font looks different (also in size) from theTouchGfx GUI and the simulator, or the code loaded into board.I don't need so i never change font in my app( is that even possible?) so i can't undestand why this is happening, for sure is not some of my code i forgot i've written...as you can see the in the left image (a touchGfx screenshot) the text have a different font and size than righ image (a simulator screenshots, but also code loaded into board looks the same as simulator)

Hi,I was just made aware of this video by "embed sys". It's a great example of the flow that we encourage using CubeMX to configure hardware and TouchGFX Designer to create the UI.While we don't encourage interfacing with hardware directly from the view classes to keep them portable (simulator + target) this video is still a great example of how easy it can be to interface with your hardware.The project does not configure the board to use the NOR flash on the 429-DISCO but simply uses a minimal configuration with no external dependencies other than the LED.https://www.youtube.com/watch?v=X1CtXPHZDP4

I am using TouchGFX with STM32F767BI and 800x480 LCD.I made a graph with reference to Graph during TouchGFX Demo.My problem is that I can't set the Y axis.How can I set it up?The data I want to display is from 0 to 120000.void Graph::setup(int newWidth, int newHeight, int bufSize, colortype lineColor, colortype backgroundColor) { setWidth(newWidth); setHeight(newHeight);   graphLinePainter.setColor(lineColor); graphAreaPainter.setColor(lineColor, getHeight()); graphDotsPainter.setColor(lineColor); graphDotsBackgroundPainter.setColor(backgroundColor);   graphLine.setLinkedGraph(graphArea); graphLine.setLinkedGraph(graphDots); graphLine.setLinkedGraph(graphDotsBackground);   graphLine.setPosition(0, 0, getWidth(), getHeight()); graphLine.setPainter(graphLinePainter); graphLine.setBuffer(graphBuffer, bufSize); graphLine.setLineWidth(1); graphLine.setRange(0, 290, 6500,0);   graphArea.setPainter(graphAreaPainter); graphArea.setLineWidth(0);   graph

I can get scroll wheel selected item index:  /**   * @fn int ScrollWheelBase::getSelectedItem() const;   *   * @brief Gets selected item.   *   *    Gets selected item. If an animation is in progress, the item that is being scrolled   *    to is returned, not the item that happens to be flying by at the time.   *   * @return The selected item.   */  int getSelectedItem() const;But I Need programmatically set selected item

I have one base application and have multiple applications and want to open close these multiple apps without closing a master application. All of them are created as an individual touchgfx project. Like in windows form application we open exe app using process.start and close exe app using this.close function . Is it possible to include all the projects created by different programmers in a single master app and then select any one of them

Hi,I need to show "Yes/No" modal dialog when a sensor value goes over limits.Why there is only Show/hide/move widget action, but no Action to show container? I'm I missing something here and thinking this wrong?Should I make Custom Widget instead, or should I call C++ function that can show Container?Thanks!

I am working on STM32F746 based custom board which is integrated with LCD and a ADV7180 video decoder IC. I Configured the ADV7180 to run in the free run mode. Getting the Camera data using DCMI to a specified buffer. I am trying to Convert the YCbCr 4:2:2 data to the RBG data. I am getting the Line Events. .From the Live events I am executing the below piece of code to convert it to the RGB and then load the it to the LCD using ARGB888.LCD_FRAME_BUFFER 0xC0000000LCD_FRAME_BUFFER_LAYER1 0xC0130000CAMERA_FRAME_BUFFER 0xC0260000void LCD_LL_Test(void *pSrc, void *pDst, uint32_t lcd_offset, uint32_t cam_offset) { uint32_t * pTempDest = (uint32_t *)(LCD_FRAME_BUFFER_LAYER1); uint32_t * pTempSource = (uint32_t *)(CAMERA_FRAME_BUFFER+cam_offset); uint32_t * pFinalDest = (uint32_t *)(LCD_FRAME_BUFFER+lcd_offset); uint32_t * pFinalSource = (uint32_t *)(LCD_FRAME_BUFFER_LAYER1);   for(uint32_t i = 0; i < (480/2) ; i++ ){ uint32_t te = *pTempSource; // CB Y1 CR , RESULT toR

Does anyone know if there is there an example somewhere of usage of the method copyFBRegionToMemory()?The documentation says that the buffer can be a dynamic bitmap and I am having issues getting my code to compile.

Hello,I tried to use tim2 in my firmware but in CubeMX when TouchGFX is enabled tim2 is disabled..In TGFX tab there is a parameter "Timer for Instrumentation" where I can choose between timer 1, 3, 5, 8 and 12, but is it doesn't affect tim2.Is possible to use tim2 when I'm using TouchGFX?"Timer for Instrumentation" is used for what?Regards.

void MainScreenView::setVacuumPositionPercentBoxClickHandler(const BoxWithBorder& b, const ClickEvent& evt) { // When target vacuum position box is clicked, display modal keypad with numericals targetPercentModalWindow.setVisible(true); targetPercentModalWindow.invalidate();   keyboard.setPosition(410, 100, 320, 240); add(keyboard);   }This is the code where I make the modal window visible and draw the keyboard.

I recently created a project for the Stm32F746G-Discovery kit in TouchGFX 4.12.3 and chose version 2.0.0. I was only able to select 24 bit color depth. When creating a new project in STM32CubeIDE 1.1.0, I was only presented with one option for the STM32F46G-Discovery kit, so I chose it. I see that it is only 16 bit color depth as seen in the BoardConfiguration.cpp file as well as with in the Stm32CubeMX > Middleware >TouchGFX section.Am I missing something, is there a way to set this up?
