Hi,I’m experiencing issues configuring a display using a custom PCB with the STM32H747BIT MCU and LVGL for the UI. Currently, the project runs a minimal setup with only one loop calling lv_timer_handler();. At this point, my main goal is to get the screen working correctly.I’m using LVGL in direct mode for the display buffers.The issue I’m facing is that the screen occasionally shows horizontal glitches. I’ve created a simple spinner using the following code: /* Create a spinner */ lv_obj_t * spinner = lv_spinner_create(lv_screen_active()); lv_obj_set_size(spinner, 64, 64); lv_obj_align(spinner, LV_ALIGN_BOTTOM_MID, 0, 0);You can see the glitch in the attached video.As you can see, the glitching is more noticeable in Video_1 than in Video_2. These are the display timing configurations used for each:Video_1:Video_2: Please note that the configuration in Video_1 follows the manufacturer’s recommended settings. In Video_2, I performed some tests and observed that increasing either

I'm encountering a persistent issue when setting up an STM32Cube project in VS Code. Even when reverting to a previously working commit or starting a fresh setup from scratch (using the "Setup as an STM32Cube project" button), the process fails.The following error message appears:"Cube project discovery CMake configure step failed. Setup might be incomplete. Please check output logs"I have tested this on two different machines running both Linux and Windows, but the result is the same.

I have a problem with disabling gfxmmu. I don't have a rounded display so that actually I do not need GFXMMU.I created a project by using Touchgfx Designer Templates (STM32H7S78 DK BPP). GFXMMU is activated in default. I would like to disable it. So, I disable it in cubemx then exclude instrumantation files. Then I updated TouchgfxHal.cpp and frame buffer adresses as 0x9000 0000 - 0x9020 0000.Then I could succesfully build the project. When I run it, it is working particularly but the frame/image is broken down. I am adding the image here!Could you explain me how to enable or disable gfxmmu properly from project?

Hello, I read somewhere that I can use the ST-LINK built into my H563ZI to program my custom cards with STM32F401.Could someone help me figure out how to do this?Thanks in advance.

Hi,I have setup three channels in Timer_2 on an 32F429 MCU and have come across a seemingly inconsistent behaviour with regards to the alternate functions mentioned on the datasheet.More specifically, I have setup pins PA0, PA1, PA2 for Output_Compare, Input_Capture and PWM against channels 1, 2 and 3 of Timer_2 respectively and although the behaviour I observe on pins PA0 and PA1 is the expected one (well nearly the expected one but will ask a new question a bit later as that's probably a separate issue), pin PA2 is entirely dead as I don't get any pulsation happening whatsoever.I checked my configuration again and again in order to make sure it's setup correctly and verified the alternate functions I've setup for the gpio pins match the datasheet but that all looked fine:I then scrolled a bit further down on the datasheet and noticed that there's an alternative alternate-function pin for Timer_2 channel 3, namely PB10:So, I tried configuring that for the PWM pin and voila, it al

I used to work with Nucleo board STM32G474 and programm them. Recently I can not open the file to programm my devices. I looks a window problem.I installed again all the ST Tools but the problem remain.I can not open files.

Hello everyone, I'm facing a very frustrating issue with USART2 on my Nucleo-L475VGT6 board using the built-in ST-LINK Virtual COM Port. What works: - ST-LINK is detected (COM3 appears, Windows sound plays on connect) - Code downloads successfully (no error in CubeIDE console) - LED blinks (proof that main() is reached and while(1) is running) - HAL_UART_Transmit is called  What does NOT work: - Nothing appears in any terminal: MobaXterm, PuTTY,  PowerShell serial reader - No garbage, no partial characters, just black screen - Same behavior in Run mode (no breakpoint) and after physical Reset button MY code: /* USER CODE BEGIN 0 */ uint8_t tx_buff[]={0,1,2,3,4,5,6,7,8,9}; /* USER CODE END 0 */ while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ HAL_UART_Transmit(&huart2, tx_buff, 10, 1000); HAL_Delay(10000); } What am I missing? Is there a jumper / solder bridge I forgot on Nucleo-L475VGT6 for VCP? Or is there a known bug with USART2 VCP on L4 series? Tha

Hello,I want to generate four 50% duty cycle frequencies up to ~12kHz. It should be possible to enable/disable single outputs. Currently no special high requirements about accuracy, etc. Using a STM32U0 device (56MHz max).My first thought was to use an upcounting timer with four output compare channels where the timer itself is free running (ARR set to max. value). The compare channels are set to toggle on match and on each OC interrupt, the corresponding CCR register value is set to the next equivalent ARR value to toggle again. For example, if the timer is running at 1MHz and 1kHz frequency is needed, 1000 will be added to the CCR. To start/stop the output, I'd modify the corresponding OCxM value between toggle and frozen mode.However, I'm not sure if this is the most efficient way, especially regarding overhead and complexity. Another solution which came to my mind was to use a DDS approach with a (low power) timer, constantly firing interrupts at the needed resolution. On each

I try to start working sdMMC with DMA. When D-Cache is not active work well. But when turn it on stop work. Probably need to create MPU region , but where is located used RAM from sdMMC. And if need, how to change .ld file? 

  Currently designing a PCB that has a USB-C 16 pin connector. For maximum flexibility the PCB can take either a H723 or a F723 MCU. (The H723 has USB FS pins only, whereas the F723 also has USB HS pins available). This design allows it to operate in either USB in FS or HS modes but with only a single USB C port. 1 - What is best practice for wiring up the STM32 USB ID pin (FS or HS) in a USB-C scenario? Do I leave it floating, grounded, or does it need to be connected to one or both of CC1\2 ? 2 - Regarding USB connectivity, can I connect in parallel the following MCU pins (since both sets are inputs to the STM MCU)   pin 69 (FS_ID) to pin 51 (HS_ID)?   pin 68 (FS_VBUS) to pin 52 (HS_VBUS)? 3 - For question 2, when using a H723 MCU, pins 51 & 52 would be configured as GPIO inputs. When using a F723 either USB mode could be used, so its possible pins 68 & 69 would be configured as GPIO inputs instead. Would this parallel connectivity idea adversely affect FS_ID a

Hi everyone, I’m new to STM32 development and need some help configuring CLion for working with STM32 microcontrollers. I have installed STM32CubeMX (version 6.13.0) and am trying to generate a project for my STM32F411CEU6 microcontroller. However, I’m encountering an issue where the Eclipse launcher fails to work, and I can’t proceed further. I’m using macOS Sequoia (version 15.2). Could anyone guide me through the process of setting up CLion on macOS to work with STM32? Any advice, steps, or resources would be greatly appreciated! Thanks in advance!

Hello,  I'm trying to DFU update some binaries into 1Mbyte STM32WB55CG Flash with OpenBootloader Custom APP. I've tried before with NUCLEO-WB55RG board without any problem, but with CG I just can erase/write until the first Block (512KB) of the memory. Always crashes from there. I've checked the option bytes and FUS parameters and everything looks normal. I don't know if you have some idea why this behavior. In the post attached some captures.  I've got this contact @Alan PORTE from a colleague, but any help will be welcome. Thank you.

The HSEM option is not found in "System Core" in STM32CubeMX (version 6.15), and the configuration option for HSEM interrupt is only found in NVIC. How to configure HSEM in STM32CubeMX. When I selected the LL library environment, the generated source code did not import the HSEM LL library header file. How to solve these two problems? If it is not possible to configure and import the HSEM related library files into the project file in STM32CubeMX, please let us know.

I want to implement a USBPD sink application with a 9V PDO and I am struggeling to set up a PD-contract with a source. I am using following components:STM32G0B1 MCUTCPP03-M20 PD controllerMy project is based on this example: https://github.com/STMicroelectronics/x-cube-tcpp/tree/main/Projects/NUCLEO-G071RB/Applications/USB_PD/DRP1M1_DRPX-Cube-TCPP v4.1.0 When I attach a PD-source, the DPM_Params[_port].PE_IsConnected variable is successfully set.After that I get in USBPD_DPM_Notification a USBPD_NOTIFY_POWER_STATE_CHANGE event and afterwards a USBPD_NOTIFY_HARDRESET_TX event.I also notice that I do not receive a message within PORTx_IRQHandler, as I do not jump intoif (UCPD_SR_RXMSGEND == (_interrupt & UCPD_SR_RXMSGEND))…Do you have any tips for me where I can start looking for my missing piece? Did i initialize something wrong?

New question moved from this post. @mƎALLEm Hey! Thanks for the quick response. I saw your post from a previous thread with a same question but for the STM32F407VG.https://community.st.com/t5/stm32-mcus-products/stm32f407vg-adc-injected-channel-with-dma/td-p/652531 Is the DMA Peripheral in STM32F407VG same as GPDMA Peripheral in STM32U5? The STM32U5 Series has a GPDMA Peripheral which looks to be different from the F4 DMA.Thanks!

Hello, I trying to use DMA on USART6, but in handle list USART6 is unavailable:   I ques what there is some CubeMX error because in stm xxx_hal_dma.h file this uart is added to list: #define GPDMA1_REQUEST_USART6_RX 117U /*!< GPDMA1 HW request is USART6_RX */ #define GPDMA1_REQUEST_USART6_TX 118U /*!< GPDMA1 HW request is USART6_TX */  For now I will try to setup manually, but I still on question about this issue ?
