Hi, I've installed TouchGFX designer 4.26.0 on my laptop and i see a difference in behaviour to the previous versions.The problem is that we want to update our IAR project ewp file as we change or add new items in our designer. However we have issues when we do. At the moment our designer makes the following change<option> <name>IlinkAdditionalLibs</name> <state>$PROJ_DIR$\psi_board_lib.a</state> <state>$PROJ_DIR$/../../lib/touchGFX/touchgfx/lib/core/cortex_m7/IAR9.x/touchgfx_core.a</state> </option>changes to <option> <name>IlinkAdditionalLibs</name> <state>$PROJ_DIR$\psi_board_lib.a</state> <state>$PROJ_DIR$/../../touchgfx/touchgfx/lib/core/cortex_m7/IAR9.x/touchgfx_core.a</state> </option>That would not be a problem if the new folder "$PROJ_DIR$/../../touchgfx/touchgfx/lib/core/" was not empty after every build.I've tried to set the files back into that folder but every tou

Hi, I am trying to transition from cubeIDE to the VSCode workflow, and am having trouble getting intellisense working. I'm relatively inexperienced with this (I appreciate that cubeIDE 'just worked' in this regard, and I never had to deal with figuring out how to configure this). I've tried starting from a relatively vanilla state - I only install the STM32CubeIDE VSCode extension pack. I *think* I need to also install the C/C++ extension from MS in order to get/enable intellisense for developing stm32 projects (?)Within my project, some things seem to work - I can right-click on some functions and see/jump to definitions. In other cases, I see errors about undeclared variables/defines/macros or other miscellaneous "problems", none of which the compiler actually complains about. I'm confused why this seems spotty within the project. Then, I have an out-of-project shared code area. I've set this up relatively simply (there are no "library" CMakeLists.txt files in this area, ju

Post Edited by ST moderator to apply source code formatting to comply with the community rule: I wonder if any one can help me.The rtc Cal freq produced by the init code below produces on 490Hz.  The RTC clock is loosing about 55 sec in 20 minutes.Is there a way to increase this freq without replacing the crystal?     static void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 */ /** Initialize RTC Only */ hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.Init.AsynchPrediv = 127; hrtc.Init.SynchPrediv = 255; hrtc.Init.OutPut = RTC_OUTPUT_DISABLE; hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH; hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN; if (HAL_RTC_Init(&hrtc) != HAL_OK) { Error_Handler(); } /* USER CODE BEGIN Check_RTC_BKUP */ /* USER CODE END Check_

Hi,I am using Nucleo-L476RG. My I want to send data over SPI every 20000ms and during this 20000ms MCU will goes in sleep/standby mode. I want to keep track time of last 2 SPI data transmission.But the issue is HAL_GetTick() reset after waking up from standby mode. so not able to track the time between last two data transfer.

1. Run StmCubeMX and then chose upgrade in Ubuntu2. After download it error with something alike it cannot unzip the file.  Reason:1. it seems CubeMx uses the .installationinformation hidden file in its folder to find the installation folder.INSTALL_PATHt\00$.....<your patch>/STM32CubeMXt\These are settings  in a binary format, so there are some weird character. Anyhow it cannot be changed by user.Solutions:1. Move CubeMX back to where is was installed (not desired) after upgrade, move it back where  it is desired.2. Remove and Reinstall CubeMX Suggested fix:1. Make CubeMx upgrade process install folder agnostic.     

Hello      I'm working with the STM32N6570-DK board to capture images using the IMX335. I want to save 480x800 images from PIPE1 of DCMIPP to External RAM. I've tried searching for examples on the STMicroelectronics Github, but most examples save to AXISRAM. Does anyone have simple example code or steps for doing this? Do i need to config xSPI first? or do i need to put something into ".ld" file?

Hi,I'm in charge of the motor driver for a new project we've started working on. I freshly installed MotorControl Workbench, CubeMX and the IDE. After setting all parameters in Workbench and hitting "Generate the project" button I get a Java runtime Exception "unkown protocol c". I've hit a wall trying to fix this as there's almost no info about similar issues on the web.I tried uninstalling and installing different versions, too.Using windows 11 pro, 24H2. Any suggestions what might go wrong here? I've tried installing the oracle JDK and using that instead of the openJDK runtime but I couldn't get Workbench to use it (this was the only info I could find).Thanks for any help on this!

I’m using an STM32F439VIT6 on a custom board. PA5 is used as the DAC output, and PA0/PA1 as the ADC inputs. On 1 out of 5 boards, the ADC and DAC functions stopped working, but the same pins still work correctly as GPIO.Setup (failing board)PA5: DAC → op-amp → 0–10 V outputPA0, PA1: ADC inputs from INA190A1 for 4–20 mA sensorsVDDA/VREF+ = 3.3 V (measured OK)Same firmware as working boardsPins configured in analog modeIssueDAC produces no valid analog output, always zeroADC readings are invalid or stuckGPIO input/output on the same pins worksQuestionCan the STM32F4 analog (ADC/DAC) circuitry be damaged while the GPIO still works on the same pins?How can I confirm if the ADC/DAC core is damaged (e.g., internal channels/tests)

Hi all,I am using an STM32H5 micro. I need to send out a buffer of data at regular intervals. I use TIM15 to trigger the GPDMA which sends blocks of 6 bytes to the SPI. The SPI is programmed with TSIZE=6 to get the SS output low during the transmission. I absolutely need this. The screenshot below is the result from my code.My problem is that the SPI only works ONCE. It seems to be stuck afterwards, I observe that CSTART of the SPI goes to 0. How can I get the SPI going on with TSIZE > 0 ?

Hi,I am working in steval-esc001v1. I have set the a2212-13t-1000kv bldc motor to ran at minimum of 1000 rpm and at maximum of 9924 rpm using the foc algorithm in the motor control workbench software. I have ran till the 8000 rpm. But our goal is to ran any type of motor with in the ESC's voltage rating of 3S to 6S (11 V to 22V), also Is it possible to calibrate esc by giving maximum pwm input and minimum pwm input without profiling the esc using pc software every time if the motor changes? If not possible, how does the general ESCs available in the market can do that. If anyone worked in these area, kindly assist.Thanks and Regards,Santhosh. 

I’ve been working with STM32 microcontrollers for a while now and recently I ran into a challenge when trying to optimize UART communication for low-power applications. I noticed that a common issue arises when buffers overload during sleep–wake cycles, which can lead to missed data or timing glitches.After experimenting with a few techniques, I found that integrating DMA with interrupt-driven control logic provides a much more reliable data stream while still keeping power consumption down. In particular:Configuring UART with circular DMA greatly reduces the risk of buffer overrunsUsing USART idle line detection allows you to trigger data processing only when neededAdjusting NVIC priorities helps maintain responsiveness when multiple interrupts are activeI documented the full approach step-by-step with configuration settings and example code on my blog, in case it’s useful for anyone tackling similar problems::right_arrow: https://summertimesagas.com/Would love to hear your thoughts —

Hi, I would like to capture a TextArea's content and use it with TextureMapper for scaling animation and a blurry filter effect on the bitmap data.However, there is noise for the TextArea background in HW, but the simulator result is perfect. The reasons for using TextureMapper with Bitmap Data:the TextArea content will be updatedthe screen background will be updatedfilter effect function will be applied to the TextArea's contentAble to implement the scaling & fade animation How to create a Bitmap Data with Font/image's content without a noisy background?----------------------------------------------------------------------------STM32U5G9-DK Result (noise for the Background):Simulator Result (expected):----------------------------------------------------------------------------The Dynamic Bitmap creation (Reference to advanceAnimationContainer.cpp in Text Animation Demo):TestFont1Bitmap = Bitmap::dynamicBitmapCreate(Container.getWidth(), Container.getHeight(), Bitmap

STM32F4 is working in USB Device MSC mode successfully.I need to detect the USB connection state. I put the HAL_PCD_ConnectCallback function in main.c but on compiling I received warning.Debug/../USB_DEVICE/Target/usbd_conf.c:307: multiple definition of `HAL_PCD_ConnectCallback';I see it is weak in HAL_PCB_IRQHandler. Please suggest what I am missing.   

Is there a build tool to insert two .hex files into my final image?  I am retroactively updating an existing firmware by moving a bootloader I've created from an unused place in the updated image into its proper sector. But to do this, I need to insert the bootloader into the image I am updating with. (Update image contains existing code + boot image1 + boot image2) My main update image will be contained in sector 0 - 5. My first separately built bootloader.hex file must be squeezed into sector 6, and my second separately build bootloader2.hex must be squeezed into sector 7.  I have found it is possible to use the linker file to insert raw hexadecimal bytes, but this requires converting the .hex file to an ascii hex array, copying it over and then building. Is there a command line build tool alternative to do this cleanly?

Previously, I used this delay function in inline assembler in my projects (on Cortex M3, M4): static inline void delay_m4(uint32_t cnt){ asm volatile( "1: SUBS %0,#1" "\n\t" " bne 1b" :"=r" (cnt) : "0" (cnt) ); } Now I'm trying to add this function to a project on a Cortex M0+ microcontroller (STM32G0XX).The compiler gives me this error message:Error: instruction not supported in Thumb16 mode -- `subs r3,#1'I'm sure this is a compiler error because:1) the documentation for the Cortex M0+ "PM0223" lists the subs instruction as available;2) looking through the assembly listings of other Cortex M0+ projects, I see thatthe subs instruction is used constantly.

I am trying to run this demo, but I am receiving an error.How should I program this board? Should I use an ST-LINK or a USB-to-TTL adapter, or is a direct USB Type-C connection sufficient? I am trying to program it via TouchGFX Designer.

Hello, i am trying to store adc calibration data in flash on my H7A3 project.Writing the data (64byte, flash addr 16byte aligned) is successful (at least i hope, since i get no errors), but when reading the same data back from flash via that same Bank2 memory address, i only read zeroes.I was trying to use a same approach like the example program.Can somebody review my code and point me in the right direction?#include "stm32h7xx_hal.h" #include "stm32h7xx_hal_flash.h" #include "string.h" #include <stdint.h> #include "settings.h" #define FLASH_USER_START_ADDR FLASH_BANK2_BASE /* Start @ of user Flash area in Bank2 */ #define FLASH_USER_END_ADDR (FLASH_BANK2_BASE + FLASH_BANK_SIZE - 1) /* End @ of user Flash area in Bank2 */ // get flash sector number from address uint32_t GetSector(uint32_t Address) { uint32_t sector = 0; if (Address < (FLASH_BANK2_BASE + FLASH_BANK_SIZE)) { sector = (Address - FLASH_BANK2_BASE) / FLASH_SECTOR_SIZE; } else { sector = (Address - (FLASH_

Hello, I'm trying to run SDRAM (AS4C4M16SA-5TCN) with FMC. It looks like all connections are correct. When I try to read/write to memory pointer, I got memory management fault handler.My FMC configuration:Clock connected to FMC is 275MHz (HCLK3). I've tried also to lower it to ~30MHz, but it didn't help.Under "USER CODE BEGIN 2" I'm executing FMC_Init() function. This is it:I tried to write something to memory, but this is the moment when fault handler is activated:*(__IO uint8_t*) (SDRAM_START_ADDR) = 0x00;SDRAM_START_ADDR is defined as 0xC0000000.All FMC's GPIOs are set to Very High speed. What else can I check?@Tesla DeLorean maybe you could help, please? 

Hi everyone,I’m trying to design my first PCB using STM32F103 and I’m still a beginner.I see that the PAx pins (PA0–PA15) have multiple alternate functions like GPIO, ADC, USART, SPI, etc.I’m a bit confused about how to properly choose which PA pins to use for my peripherals.If I use PA9/PA10 for USART, can I still use them as normal GPIO later?What is functionality of PAx pins ?I'm using STM32F103C8T6stm32f103c8 datasheet stm32f103c8t6 I'd really appreciate some guidance before I finalize my board layout.Thanks! Best Regards !

Hi ST Support Team,I'm developing a simple FSBL application (LED control) on a NUCLEO-N657X0-Q board to understand the boot management flow with FSBL and application separation.What I've done:Successfully tested the application running directly from RAM via debuggerCompiled the FSBL for external XSPI flash (linker configured for execution from AXISRAM2 at 0x34180400)Signed the binary using STM32_SigningTool_CLI with header v2.3, -nk flag (no keys), -of 0x00000000, and correct load address/entry pointProgrammed the signed binary to external flash at 0x70000000 using STM32CubeProgrammer with the appropriate external loaderConfigured BOOT0=LOW, BOOT1=LOW for boot from XSPI flashThe problem: The Boot ROM does not load the FSBL into RAM.

Hello everyone!   I got the following problem; I need to read from two 32bit addresses and write the data to three. Specifically, i am interested in the case shown in the left side of the image, where the N[0:15] increment by half word and write to the M[0:15] but it will increment by a full word. Don't worry about the reserved bytes in the HTIMx_CC1R, I checked the manual and are always at zero.  I saw that the H7 can read/write with weird patters using the fifo functionality. The thing is I can't understand at all how to set it up. Is there any other better way?   Thanks in advance!
