STM32 MCUs TouchGFX and GUI

Hi @Martin KJELDSEN​ I added two tasks in main.cpp. If I added other tasks apart from GUItask, the LCD is displaying image. If I add vTaskDelay(40);, the image is show.n. Is it neccessary to add vTaskDelay in other task delay????Should I add vTaskDelay in each task to display image in LCD???

I have read the thread discussing this topic, but the resources it points to only covers Application Templates - not User Interface Templates.Is the packing of UI templates analogous to those of ATs or is it a different process altogether?

Hello,I have an STM32F429 Discovery board. I would like to know how to interface both the LCD-TFT display and the CAN communication protocol. As I don't see any free pins for the CAN protocol after interfacing the LCD-TFT display. Please find the link for the data sheet of the discovery board, https://www.st.com/content/ccc/resource/technical/document/user_manual/6b/25/05/23/a9/45/4d/6a/DM00093903.pdf/files/DM00093903.pdf/jcr:content/translations/en.DM00093903.pdfData-sheet of STM32F427,https://www.st.com/resource/en/datasheet/stm32f429zi.pdfReference manual for STM32F4xxhttps://www.st.com/content/ccc/resource/technical/document/reference_manual/3d/6d/5a/66/b4/99/40/d4/DM00031020.pdf/files/DM00031020.pdf/jcr:content/translations/en.DM00031020.pdfPlease do let me know which pins I have to use in-ordered to interface both the display and the CAN. Thanks in advance :D

Hey,I tried generating an empty project using STM32CUBEMX (Followed instructions from: https://touchgfx.zendesk.com/hc/en-us/articles/360021620431-Configuring-STM32F429I-DISCO) When I try to compile the project in keil I get the following error:(Sample error line: SixthTrial\SixthTrial.axf: Error: L6218E: Undefined symbol touchgfx::TypedText::fonts (referred from texts.o).)hence after looking up for a few other forums I tried updating my touch gfx in the project folder and got this output:(Sample error line: Using touchgfx E:\TouchGFX\4.10.0\env(MINGW32) Updating 'simulator/gcc/Makefile'(MINGW32) Generating assets.make[1]: *** No rule to make target )Please let me know where I am going wrong. Thank You.

Hi,I would like to use SD card to store the image files. Can you please help me to guide how to store these files in SD card?

Hello,I have 32L4R9IDISCOVERY board with round display. When I set clock configuration of MIPI DSI there is one error. DSI rxclkesc is same as DSI lane byte clock if lane_byte_clock is fed from DSI-PHY. For 32F469IDISCOVERY DSI clock setting there is no rxclkesc (i think it should be same as txclkesc).I want to use DSI-PHY clock for lane byte clock. Whats wrong ?ThanksEDIT: I am using STM32CubeMX version 5.1.0.

Hello all,I am trying to configure a click event upon a scrollwheel for selecting an item.I am using Callback for achieving this.Inside a handleClickEvent(), I need to give a callback to a CallbackHandler function. This function will eventually call scrollWheel1UpdateItem for performing any actions related to click event. I am getting confused with the syntax related to declaring a callback and initializing it inside SetupScreen()Please help me with the correct way of doing this and correct syntax for Callback declaration and usage. Following is Screen1View.hpp #ifndef SCREEN1_VIEW_HPP #define SCREEN1_VIEW_HPP   #include <gui_generated/screen1_screen/Screen1ViewBase.hpp> #include <gui/screen1_screen/Screen1Presenter.hpp>   class Screen1View : public Screen1ViewBase { public: Screen1View(); virtual ~Screen1View() {} virtual void setupScreen(); virtual void tearDownScreen(); void scrollWheel1UpdateItem(CustomContainer1& item, int16_t itemIndex); void

Hello,I am configuring ScrollWheel on touchgfx.In order to select an option, I need to click on ScrollWheel.In order to browse all the options, I need to drag on ScrollWheel. So, I need both handleClickEvent() and handleDragEvent(). I also need to differentiate between a Click and a Drag action.But, upon drag action, my program control goes in handleClickEvent() only. It never reaches handleDragEvent() function.Please suggest how can I detect Drag event?

Hi.I am using the uart on the touchgfx project on the stm32f746-disco board, but when I continue the uart interrupts, I get stuck.There were two cases of stuck state.1. Screen stops but uart is running2. Board is completely frozenThe uart interrupt code I created seems to be wrong and I am not sure how to fix it and I need help.I am currently switching four 480 * 272 screens every 4 seconds using only the resources that the 746disco board has, and I am in the process of testing qspi MemoryMappedMode.Ethernet does not cause any problems when sending and receiving data in 100ms increments. In case of uart, the board is stopped after a certain period of time even though data is transmitted much slower.Below is the uart code that I use.The reason for this is that the interruption of the uart HAL library, which works normally in other projects, is not responding to the projects ported by touchgfx.This is only a problem with rx interrupts.In case of tx, I am using polling method instead

I've configured bank1 FSMC to drive a LCD using CubeMx copying the various example code. I've set up FSMC-A18 to be the pin driving the Control/Data selection on the LCD. All data lines + OE and WR work perfectly but A18 sits continuously low whether I write to REG or RAM. I can't see in the examples how this is supposed to work as I can't find any code that sets whether it should be high for data/low for control or visa versa. The pin itself works fine if I drive it direct. This is my first use of FSMC and I'm clearly missing something - help appreciatedI can attach code and CubeMX images if that helps diagnose

How to implement message notification reminders, for example, in different interface can remind the user.

Porting the basic JPEG_DecodingUsingFs_DMA from Discovery to custom hardware and I'm failing with the hardware JPEG decoder. The image decodes fine with the software decoder in STemWin and although I seem to be getting the HAL_JPEG_IRQHandler interrupt which indicates the header is ready, HAL_JPEG_GetInfo reads all zeros.All initialisation is from CubeMX so of course I'm using the HAL library but I'm wondering if Cube is missing something - maybe initialising in a different order?The same image decodes fine on the Discovery board by the way...Hopefully this rings a bell with someone.

I'm trying to connect stm32f103c8t6 board with ILI9325 LCD display. I have created a driver for it in Atollic TrueStudio and run it successfully. Now, I am trying to transfer the driver to the Arduino IDE, because here it will be easier to integrate my code with the other code for this project. However, the driver doesn't work in Arduino IDE. The LCD is just blank.I have tested the basic GPIO operation in Arduino IDE for stm32f1, it works fine. I have checked the pins on the LCD. They seem to receive command from the board. All the wiring is correct, because the screen works with the code from Atollic without any wiring change.This is the driver code I use in Arduino IDE. It's basically the same as the one in Atollic. All I changed is the functions of initializing and setting GPIO.#define LCD_RESET_Pin 9 #define LCD_CS_Pin 8 #define LCD_RS_Pin 7 #define LCD_WR_Pin 6 #define LCD_RD_Pin 5   #define TFT_W 320 #define TFT_H 240   #define WHITE 0xFFFF #define BLACK

I'm trying to test this Ui example for STM32F469, from this sitehttps://touchgfx.zendesk.com/hc/en-us/articles/205074561-Connecting-the-UI-to-your-systemMethod 2 - From other taskthe simulation on my PC works fine, but when I'm trying to run on my screen/STM32F469, the screen goes crazy, My TouchGFX version is 4.10Please help me to fix thisThank you

When we've moved from the development board to our own, custom hardware, we've started to look at the power consumption of our system as a whole. Obviously, the rendering process makes up a considerable part of our power budget.When we've performed some rudimentary benchmarks on power consumption, it looks like the touchgfx application draws power even though we're not rendering any new stuff on the screen (which, by the way, is not using any touch controller HW or SW).Moreover, when touchgfx is running, the power consumption seems constant - regardless of what's being updated on the screen. The only significant variable to power consumption seems to be the framerate.(When blocking the touchgfx application from executing altogether, we save about 50mA on our STM32F769 MCU.)Now, I know touchgfx is only supposed to update the parts of the framebuffer that have changed from frame to frame. But how is the touchgfx backend oriented for power efficiency?Are there any useful rules of thumb in

I didn't find “dynamic_bitmap_example“ in TouchGFX

Hello,I am currently trying to load a very simple TouchGFX (v 4.10.0) project to my STM32F469i-discovery (just a scene with a white background, a text and a button). I created my project using CubeMX (v 5.1.0) and I was able to compile it, the screen just show the scene in the right way, but the problem is that the Touch Screen is not working.So I noticed that the file: {ProjectRoot}\TouchGFX\target\OTM8009TouchController.cpp had some commented code, which I think i need to de-comment in order to let the Touch Screen works. The problem is that I need to include the BSP drivers which I have in an external folder on my computer: C:\users\username\STM32Cube\Repository\STM32Cube_FW_F4_V1.24.0\Drivers\BSP\STM32469I-DiscoveryI tried to add a "#include <stm32469i_discovery_ts.h>" after including the external folder into Project -> Build Settings -> C/C++ Build -> C Compiler -> Directories, but it continued to give me some errors (it could not found a reference to ft6x06_ts_d

I'm trying to get OV5642 Arducam camera module to send data to STM32F429 (Discovery DISC1 board), I am using hardware synchronization. Could you tell me what is the difference between two DCMI interrupts: IT_FRAME and IT_VSYNC? I had trouble understanding this from reference manual: "IT_FRAME - Indicates the end of frame capture, IT_VSYNC - Indicates the synchronization frame". What is synchronization frame, is it connected somehow with embedded synchronization? What does this interrupt mean if I'm using hardware synchronization?Knowing that these two interrupts probably appear after every frame I was expecting to see same amount of them. In fact, IT_VSYNC shows much more often than IT_FRAME. Additionally, amount of IT_VSYNC interrupts seems to be reasonable, compared to IT_LINE interrupts it is consistent with expected image vertical size. But why IT_FRAME interrupt is not shown after every IT_VSYNC interrupt?

Hello,I tried following a few links from ST on integrating Touchgfx with Keil (other IDEs).I am specificaly looking for steps to integrate Touchgfx generated code with Keil.I followed this link : https://touchgfx.zendesk.com/hc/en-us/articles/360019884752but got stuck at the step " Add missing BSP files and update Linker scripts" . Particularly trying to find the Keil equivalent of EWARM\stm32f746xx_flash.icf. Skipping the step did not work either.Has anyone been able to successfully integrate code generated by Touchgfx with Keil so far?Thank you.

Hi,I am working on DCMI interface of STM32f407VGT micro controller to connect external device(not camera).And i am trying to get data from external device using 8-bit parallel data lines and PIXCLK frequency as 6.3MHz. Also providing H SYNC and V SYNC Signals as Hardware Synchronization.Always i am getting data from external device(Parallel) but initial data is missing .So how can i get proper data from external device without losing initial data.Here is my configuration and Initialization code.//GPIO Configuration/**DCMI GPIO Configuration  PE4   ------> DCMI_D4  PE5   ------> DCMI_D6  PE6   ------> DCMI_D7  PA4   ------> DCMI_HSYNC  PA6   ------> DCMI_PIXCK  PC6   ------> DCMI_D0  PC7   ------> DCMI_D1  PC8   ------> DCMI_D2  PC9  &nb

I have a display with 600 x 1024 pixels (portrait) and some screens with a full sized images as background.For changing screens, I use the in the TouchGFX Designer (4.10) included action "Change Screen", transition "Slide" and transition direction "East".The transitions between the screens is not fluently and jerks.How to avoid this? Are there any examples with such a scenario?

Says in the title, where can i find the flag to remove warnings treated as errors

My current project needs multiple screens connected by sliding, so i'm using swipe container to contains the changing contents through slides, i also need to see in which screen i am, so Page indicator is perfect for that. The problem is i need a button to return to the first page, but i need that the first page is the middle one, like when sliding through pages on a smartphone. So, is it possible to change the slide configuration? Actually i have 5 slides, so layout is 12345 and the button takes me to slide 1, i need something like -2-1012 and button that take me to 0.Thanks in advance for any advice
