Currently, I am using the STM32F412RGT6 64-pin package to drive an 8-bit MCU interface screen. However, I am unsure if this MCU supports FSMC.

What are the sizes and configurations of the FIFOs (foreground, background, and out) on the STM32F427 DMA2D (Chrom-Art)?

My STM32F303VCT6 discovery board is not connecting with my STM32CUbeIDESTM32CubeProgrammer gives a "Error: No STM32 target found!" I'd appreciate any suggestions about how to fix this issue before I try rolling back the firmware on the debugger.Here's the error I get in the CubeIDE Console windowSTMicroelectronics ST-LINK GDB server.

  When I was developing the stm32u575, I needed to set the threshold for the bor (power-on reset). I wanted the device to reset when the voltage was below a certain level. While configuring the bor threshold for the stm32u575, I followed the configuration process of the stm32f405, but it didn't work. The program got stuck at HAL_FLASH_OB_Unlock(). Why did this happen? What was the problem? FLASH_OBProgramInitTypeDef OBInit; HAL_FLASHEx_OBGetConfig(&OBInit); OBInit.USERType = OB_USER_BOR_LEV; OBInit.USERConfig = OB_BOR_LEVEL_1; HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBProgram(&OBInit); HAL_FLASH_OB_Launch(); HAL_FLASH_OB_Lock(); 

I’m reading the getting started manual of STM32MP257 (AN5489) and it displays that there are internal pull-ups on CMD and D0, but not CK.Also there is a confusion if the dashed lines means they have internal pull-ups as well.My question is:If CMD, D0, D1, D2 and D3 have internal pull-ups. Why does the STM32MP257F-DK board have external pull-ups?Can I skip these external pull-ups? According to the datasheet of STM32MP257C/F (DS14284 - Rev 5), the CK, CMD and D0 MUST be high at initialisation of the BootROM.

For example, in this post:I use this link to a specific post in another thread:https://community.st.com/t5/stm32-mcus-embedded-software/stm32cubemx-file-for-the-stm32h747i-disco-usb-webcam-example/m-p/745530/highlight/true#M57279But that doesn’t work - it gets directed to https://community.st.com/#M57279 - which just shows the “home” page of the new community. If I remove the /highlight/true#M57279 part, it seems to work. 

Hi,I’m setting up a bash script (under Ubuntu Linux) to automate STM32H563 provisioning for my application using the command-line version of STM32 Cube Programmer. As part of this script, I’m setting it up to automatically perform Full Regression prior to new provisioning if the board is already provisioned. (This is being used for testing and software development, so I am likely to need to do this.)The help text tells me that I can use the “key”, “cert” and “per” arguments on the command line, along with debugauth=1, to specify paths to the key, certificate and requested permission to request debug authentication. However, the application seems to ignore these arguments completely and always asks for them to be entered in the console, so I can’t perform a scripted Full Regression as should be possible.I tried working around this by piping the output of a bash printf command into the application instead. Oddly, this seems to work for passing in the key and certificate but the selection

I m quite negatively surprised that suddenly (Ctrl+Space) stoped proposing any functions, as it is shown below:orI didn't change any settings, and suddenly it stopped working. That is why I ve searched for any similar issues like mine on the forum and I ve found:https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-auto-complete-ctrl-space-is-not-working/td-p/342759orhttps://community.st.com/t5/stm32cubeide-mcus/why-does-the-index-not-work-and-how-to-make-it-work/td-p/269134and none of these solutions worked for me..I ve also tried to revuild the C/C++ indexer or just simply to create a new project but still no changes... 

I would like a “version control” tag in the forum.Sometimes there are questions related to version control such as generated code/projects not being git friendly or users need help with setting up a gitignore.

Example here: So it invites me to “edit tags”.It even lets me add more tags:But, when I press ‘Save’, it refuses:

Hello,I am ready to use STM32C531 in project. Right now, I am using Keil MDK V5.29 and it does not support this micro. Can anybody help to tell me which Keil version support this micro? If I do not use Keil, does any other IDE/Compiler support this micro develop?  Thanks,  

Hi all! Thank you for taking time to assist me. I am attempting to make a composite USB Device on the NUCLEO-C562RE. I found the Middleware USBX examples and the core drivers exist in my toolchain at: STM32CubeC5/middleware/usbx However, I cannot seem to find the middleware configuration for USBX in STM32CubeMX2. My pack manager in the STM32CubeMX2 is set to this default value: "cube.packManager.cmsisPackRepositories": ["https://developer.st.com/st-pack-server/api/v1/pidx/STMicroelectronics.pidx"] Please let me know if I have missed anything or if you need further information from me to figure out the root issue. The examples, linked above, clearly auto generated the USBX files using the MX2 software, but I could not find the documentation that allowed me to generate those files. I would greatly appreciate it if someone could assist me with this.   EDIT: I saw this forum that says support isn't out until Q3. Does that mean I have to write the generated cod

Hello!I am working on a project using the STM32U375CGUx MCU, and I am trying to implement a Stereo Audio Acquisition system using two omnidirectional digital PDM MEMS microphones.Hardware Setup: Microphone L: L/R pin tied to GND (Rising Edge data output). Microphone R: L/R pin tied to VDD (Falling Edge data output). Both microphones share the same lines connected to the MCU: PB4 (ADF1_SDI0) for the clock and PB3 (ADF1_CCK0) for the data stream. The Issue:When configuring the peripheral through STM32CubeMX, I am unable to set up a true Stereo configuration. I can only make it work in Mono.Looking at the generated HAL initialization code, I am forced to choose either MDF_BITSTREAM0_FALLING or MDF_BITSTREAM0_RISING for the FilterBistream parameter. There is no option/macro to sample both edges (interleaved) simultaneously on the same filter instance:AdfHandle0.Instance = ADF1_Filter0;AdfHandle0.Init.CommonParam.ProcClockDivider = 6;AdfHandle0.Init.CommonParam.OutputClock.Activation =

Hello,I’m working with custom board STM32F767BITX, trying to interface Standalone USB Host MSC, with no Free RTOS.Tried different reference, below is one reference which I followed  As soon as connected USB, it shows connected but after that it loop between this two calls alternatively, USBH_LL_PortDisabled() and USBH_LL_PortEnabled() which disconnect USB and connect again and continue to do that.So I dont understand the root cause of this, what trigger this to behave like this?Please guide me to fix this issue. void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ __HAL_RCC_PWR_CLK_ENABLE(); __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3); /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDef structure. */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE; RCC

Hello, I'm using an STM32U5G7VJTx MCU with a 480x320 display, connected to the FMC in 16-bit mode, and everything works fine using the GPU2D. I'm not using an existing GUI framework.The pixel format used by the display is RGB565 (16bpp), so for gradients, I want to use dithering to soften the banding. I found this definition in the 'nema_graphics.h' file:#define NEMA_DITHER 0x80U /**< Nema Dithering */However, it seems undocumented. How do I make use of it?Kind regerds, Jack.

I am using an STM32F401RET with the Simulink STM32 support package.My problem is that I am measuring a pure sine wave from a voltage sensor. I verified the sensor output using an oscilloscope, and the waveform is clean. However, the ADC readings on the STM32 show a very low-quality signal that appears as a stepped waveform rather than a smooth sine wave.I have already tried increasing the sampling rate, running the ADC at its maximum clock speed, and using a timer as an external trigger source for the ADC, but none of these solutions improved the result.I would appreciate any suggestions on what could be causing this issue. 

Hi,I have a problem with my custom container. I made a custom keyboard container in my project (4.26.1 compile is ok).

Are there plans to update CubeMX to support MacOS 27 and later? I have just installed 6.17.0 under MacOS 26 and I get a warning to say the installer will not work with later versions:This is because support for the Intel translation layer will be removed (M series Macs are now into their 5th year).Note the CubeMX app itself does not get this - just the installer.
