STM32 MCUs TouchGFX and GUI

I would like to navigate some HTML page from the LCD of the board.These HTML pages contain text and images.Do you know if something already exists and I can put it on my projects?  Thanks.

I have been able to get the slider position using a callback function but need to set the slider position when the page is shown from a stored value. I don't need continuous updates only when page is activated.Thanks

Hello all members,I am interfacing LCD module in 8bit mode to STM32F446RE Nucleo board the connections are as below:The pin connections(if unclear in diagram):Control pins:RS-->PB0RW-->PB1E-->PB38bit data pins LCD:D0-D7-->PC0-PC7Program Lcd.c: #include "lcd.h"   #include <stdint.h>   #include "delay.h"       GPIO_Handle_t GPIOConfig;   void lcd_init()   {     /*   *   * Step1: Make Control pins and LCD 8pins as o/p   * Step2: Initialising sequence as per datasheet   */   //Each of this function enable's clock and configures the pin to o/p mode   LCDControlpins_init(GPIO_PIN_NO_0);   LCDControlpins_init(GPIO_PIN_NO_1);   LCDControlpins_init(GPIO_PIN_NO_3);   //Each of this function enable's clock and configures the pin to o/p mode for PC0-PC7 pins   for(int x=0;x<=7;x++)   LCDDatapins_init(x);     /*   * Init s

Hi,For one of our upcoming products, we're planning to use stm32u5 & therefore evaluating the uC for that purpose. It needs to have a 3.5" TFT display and we're wondering if there could be any suggestion from ST's side on that:Since there is no LTDC in STM32U5, it's connected via FMC, what could be a favorable choice for us. Lesser effort in finding/porting the driver for the chosen LCDEvaluation board with STM32U575AI MCU already comes with a display - Is there already an example code for that and could there be a 3.5" LCD in the family that could satisfy the requirements for our prototypeLooking forward to your response,Thanks a lot!

I'm currently working on my second ever TouchGFX project and keep stumbling upon the same issues as in my first one.I have a battery indicator that I would like to show on (almost) every screen. For this reason I created a container that I can easily drop on every screen and implemented a few relevant methods on this container. This battery indicator is obviously driven by hardware (a FreeRTOS message is sent from the HW task to the TGFX task, if that makes any difference). Now the Model receives these messages and notifies the ModelListener via a virtual method like `virtual void notifyBatteryVoltage(uint8_t);` or similar.Here is where it gets interesting to me:The base ModelListener cannot implement anything UI-related as it doesn't know anything about the View it will be attached to.It probably should not call anything on the base Presenter as this will couple the two aspects (ModelListener, Presenter) too tightly.Even if I implemented the previous point, the base Presenter doesn't

Hi again,I'm currently working on a TouchGFX project that requires me to have some one-time setup with some screens that are only shown to the user if the device is not yet set up, Let's call the first of these screens "WelcomeScreen" as opposed to the "MainScreen" for the sake of brevity.So, if the device is set up, I want to show the MainScreen to the user, and if the setup procedure is not yet done, I want to show the WelcomeScreen to the user. What I have tried now is add a method `bool isSetupComplete()` to the Model class.add invisible buttons that have dummy "Change Screen" interactions attached, andbasically copy the code generated when adding a transition on a button in a view, i.e.FrontendApplication& Model::application() { return *static_cast<FrontendApplication*>(touchgfx::Application::getInstance()); }and then add the following lines to the Model's c'tor:if(setupIsComplete()) { application().gotoMainScreenNoTransition(); } else { application().gotoWelcomeScree

Hi Community,When I use the Touch GFX from software packs in STM32CubeIDE and generate the project, I am getting the following errors. So, anyone is having idea how to solve this?1) region `RAM' overflowed by 1168976 bytes.2) touchgfx_ide_new.elf section `Video_RGB_Buffer' will not fit in region `RAM'. Thank you.Vins.

Using threadx rtos, spi is written to st7796 rbg565 480*320, the interface display is normal during initialization, but it is abnormal when the widget is refreshed in handletickevent

Hi,I have three projects, running on an STM32H7B3I-DK Discovery board. They Are: Complex - Using TouchGFX, a lot of I/O, timers, ADC's I2C, SPI and the other project is simple using only the ADC's. Throws SWV errorSimple   - No TouchGFX using ADC 1 and ADC 2 Only No SWV ErrorSimple   - Using Touch GFX and no other I/O No SWV ErrorWhen I debug the complex project I get an error: "Failed To Enable SWI - SWV will be disabled for this debug session" When I debug the simple project the error does not occur.Obviously it is something in the build of the complex project that is causing this. The debug settings are identical for each project and are shown in the screen shots attached.The console output for the debug build is:STMicroelectronics ST-LINK GDB server.

I'm trying to use STOP mode on my STM32F469I-DISCO evaluation board in a TouchGFX application. I call a function from the defaultTask that checks if the blue button is pressed, and if so, it enters STOP mode. I set up an event on the LCD_INT line from the touchscreen so that I can wake up when someone interacts with the screen. This all seems to work, but when I come out of Stop mode, the screen is no longer responding to touch. My STOP mode entry and exit code is shown below:void checkStopMode() {   if (GPIO_PIN_SET == HAL_GPIO_ReadPin (BLUE_BTN_GPIO_Port, BLUE_BTN_Pin)) { //Turn off display and backlight. HAL_DSI_ShortWrite(&hdsi, 0, DSI_DCS_SHORT_PKT_WRITE_P1, OTM8009A_CMD_DISPOFF, 0x00); HAL_DSI_ShortWrite(&hdsi, 0, DSI_DCS_SHORT_PKT_WRITE_P1, OTM8009A_CMD_WRCTRLD, 0x00);   vTaskSuspend( TouchGFXTaskHandle ); // Suspend the TouchGFX task HAL_PWREx_EnableFlashPowerDown();   __disable_irq(); //disable so that we don't end up in an ISR until we rec

Hi, ST's discovery boards usually have debug pin headers, but interestingly ST has removed it in the STM32F746NG-DISC board. I want to debug all LTDC signals by connecting to the oscilloscope. How do I go about that? Please help. Thank you.

Hi, There are a lot of examples about TouchGFX with Partial Frame Buffer. But all of them with SPI or I2C LCDs. Even the TouchGFX support page:LinKI want to know how should I initialize TouchGFX with partial frame buffer by LTDC peripheral. I already did with SPI LCDs and I used this function:void touchgfxDisplayDriverTransmitBlock(const uint8_t* pixels, uint16_t x, uint16_t y, uint16_t w, uint16_t h) { isTransmittingData = 1; LCD_drawBuffer((uint16_t*)pixels, x, y, w, h); DisplayDriver_TransferCompleteCallback(); }In this code function LCD_drawBuffer is defined in SPI LCD library.How should I do for LTDC?Thank you.

Does anyone have an example of how to use TouchGFX's I2C.hpp and I2CTouchController.hpp?I could not find any in the TouchGFX docs.My LCD does not have an ST-provided driver, so I am trying to use HAL_I2C_Mem_Read to implement the sampleTouch function.

Hi Community,I am working on custom Touch GFX project. I want to generate the project from STM32CubeIDE / STM32CubeMX by including Touch GFX in it and get turn ON the display.

I want to create a drop-down list of multiple fonts among which users can select and implement in a given/selected textarea. can anybody share some insight into implementing this task?Regards

I'm testing the 14-bit (or 16-bit) output from ADC to display using LTDC module.There is L8 mode among LTDC input types, so I checked the ADC output by normalizing it to 8-bit.But, what i really need is 14-bit (or 16-bit) gray output.I want to know how to set LTDC to output 14-bit gray data.

Is there a guide/tutorial that shows how to use it? How, for example, to invoke a specific "Resource ID" in order to fill a TextArea?Thanks

Is there any problem with LCD driving with HYPER RAM(OCTASPI) + FLASH(QUADSPI) setting?

Hi, I am using TouchGFX 4.16.1. Could you suggest a tutorial or some other material to add a second language to my project. Thank you.

I want to verify that the STM32L4R9 discovery kit can work in DSI video mode so that I can port the application to use a display driver that does not have a graphics buffer. I started with the TouchGFXWatch example and have that working. I then used TouchGFX Generator to change the Display Interface to Parallel RCB (LTDC) (per advice from the forum). This resulted in the initial display but no update. I then changed DSIHost to Video Mode which resulted in stripy noise being displayed. I believe I am using the latest versions of all the tools: TouchGFX 4.19, CubeMX 6.5.0, STM32CubeIDE 1.8.0.My forum reading suggests that this is hard, but possible. Can anyone enlighten me on what I need to modify under the hood to get this to work?

Hi,I'm really struggling to implement easily a GPIO function, even with the tutorials provided.I'm trying to use the GPIO class set (GPIO_ID id), but how ?It's not very well documented, there are no examples provided.https://www.touchgfx.com/documentation/html/classtouchgfx_1_1_g_p_i_o.htmlI'm trying to set a GPIO pin (I1) to HIGH via the press of the button called "button_pi1" on my UI.I'm calling a new virtual function called "toggle_gpio".Here is the code generated in screen1viewBase.cpp :/*********************************************************************************/ /********** THIS FILE IS GENERATED BY TOUCHGFX DESIGNER, DO NOT MODIFY ***********/ /*********************************************************************************/ #include <gui_generated/screen1_screen/screen1ViewBase.hpp> #include <touchgfx/Color.hpp> #include "BitmapDatabase.hpp" #include <texts/TextKeysAndLanguages.hpp>   screen1ViewBase::screen1ViewBase() : buttonCallback(t
