Solved

I have set up a UART as receiver. I use circular buffer to copy the data in. The code pretty much works ok with one exception:If the last byte of incoming data frame is to be saved in index 0 (UARTRx[0]), the data appears at this address AFTER the buffer counter indicates the data to be ready at that location. the delay could be few hundred microseconds. Is it possible that the counter is updated, but the value is still not written yet?   /* Private includes ----------------------------------------------------------*/ #include "BMS.h" #include "cmsis_os.h" #include "string.h" /* Private typedef -----------------------------------------------------------*/ /* Private define ------------------------------------------------------------*/ #define RX_BUF_SIZE 255 // must be power of 2 #define TX_BUF_SIZE 9 #define FR_BUF_SIZE 32 /* Private macro -------------------------------------------------------------*/ /* Private variables ----------------------------------

I’m using the VL53L8CH sensor with an ESP32 and developing a program in Arduino language based on Example_10_motion_indicator.c provided by ST. I successfully obtained the motion indicator output using a 4x4 map.Next, I tried switching to an 8x8 map by applying the following settings: VL53L8CH sensor(&Wire, LPn_PIN); sensor.set_resolution(VL53LMZ_RESOLUTION_8X8);sensor.motion_indicator_init(&motion_config, VL53LMZ_RESOLUTION_8X8);  However, when I checked the output, I noticed that the 1st and 2nd values, as well as the 9th and 10th values, are identical, resulting in behavior similar to a 4x4 map.Could you please advise if there are any additional settings required or if this might be related to a library issue? Any suggestions or insights would be greatly appreciated.

New question moved from this original thread. Thanks for the quick response.So basically the HW is configured in SMPS. So in order to obtain 480MHz, what changes should i do to the hardware. Or is there any way i could do it without changing the hardware?In SW, I will select LDO with scaling VOS0 or is there anything else i could do. Also i checked the threads you mentioned, It is indeed similar issue but not exactly the same as for me it works fine when im running the cores m7 and m4 in 400MHz and 200Mhz respectively. I chose "PWR_DIRECT_SMPS_SUPPLY" while running at 400MHz and it works fine. Im confused about the HW changes required to run at 480MHz or a configuration that could make it run in 480MHz without any hardware change. Thanks again.

I am doing a datalogger application with a custom piece of hardware using STM32 and FileX middleware. While datalogging, it occassionally experiences a spike in write and flush times that seems to be random to me. So I tried to make a simple application just to test it.The setup: The custom board uses STM32H563 MCU directly connected to the SD card slot hardware component. I generated my code using STM32CubeMX with FileX in standalone mode. So I am not using LevelX or ThreadX (from Azure RTOS). The SDMMC peripheral has a clock speed of 25MHz, with 0 SDMMC clock divide factor. This gives me the maximum SD default speed according to the reference manual. The SD cards used are FAT32 with 4096KB sector size.For debugging and testing purposes, I am continuously logging an array of 32768 bytes that is in the program. I have given the media file 102400 bytes that is aligned to 32 bytes. The code is simple. With the media and file open, the code writes the 32KB of data and immediately flu

Hi, I am using the STM32 NUCLEO-F401RE board and have already use the HAL APIs to blink the led. now I want to blink the onboard user led [LD2] using the FTDI module and want to use the USART6 for it can anyone please help and explain me in detail that how I will be doing this?

Whenever i am trying to post data i am facing this error this is making my system reboot everytime. I am using STM32F417VETX controller.

STM32H735G-DK debug QuestionI try to use board STM32H735G-DK.I connected JP7 to the STLK to change the power source and connected the PC and board via CN15 with USB microB.In STM32CubeIDE 1.13.0, I make project for the board and debug ( Fig.1 ).I haven't added anything to the created files, but debugging failed ( Fig.2 ).The state of the board is・the monitor is white screen・LD1 and LD2 is not light・LD5 is green and LD6 is redFig. 1 Fig.  2 I thought it might be a deadlock state, so I tried to recover from the deadlock using the STM32CubeProgrammer method as described in the documentation ( https://www.st.com/resource/en/user_manual/um2679-discovery-kit-with-stm32h735ig-mcu-stmicroelectronics.pdf 6.2.4).When I debug after running the method, I get Figure 3 in the debug console. If I debug again I get back to Figure 2.What was wrong with my settings?Could you please give me some advice on how to restore the state and perform debugging?Fig. 3

Hello,I am a beginner, so forgive me if my question is basic.I'm currently working on building a TouchGFX application that reads CAN Values and displays them on the STM32F746F Discovery Board. However, when I try to run the application, the program builds and downloads successfully before I get the error "Could not halt device (18)" and the screen on the board shows up white. So far, the only things that I have done to the application after generating it from TouchGFX is change the clock configuration and activate CAN1. I've attached screenshots of both in case they may be of use.What do you think is causing the error?Thank you.  

These excellent articles make the USBX worth a go for more complicated tasks (I wish composite devices were supported in CUBE IDE),How to implement the USB device composite class in STM32 using the Azure packageHow to implement the USB Device CDC (VCOM) in STM32 using the Azure USBX package When creating a composite device, I see that USB_OTG_HS was used rather than the USB_OTG_FS. I know that the HS can use the internal FS PHY STM32 (so it is FS under-the-hood). However, it also changes the pins! My particular application is highly constrained, and I cannot change the pins, so I need to use USB_OTG_FS.  Can I use USB_OTG_FS along with Azure USBX to create a composite device, or does it require USB_OTG_HS? Regards,Daniel

Hello, I'm using STM32CubeIDE Version 1.17.0. A project import from an older Verionen causes an Error message while compiling: Errors occurred during the build.Errors running builder 'CDT Builder' on project '<Projectname>'.Internal error building project <Projectname> configuration DebugEmpty command It seems to be caused by the postcompile scripts:arm-none-eabi-objcopy -O binary ${BuildArtifactFileBaseName}.elf ${BuildArtifactFileBaseName}.bin;arm-none-eabi-size ${BuildArtifactFileBaseName}.elf; The error disappears, if I remove the scripts. Other imported projects are compiled without any errors. Does somebody have a hint for me? Greetings H.

 I am working with the STPM34/STPM33 chip and using the STPM34 evaluation board. I have noticed in my own hardware and the eval boards that when you attach power to measure voltage it shorts something and blows up. Is this a known issue? Is there a known solution. I attached a photo. Looks like a resistor that's blowing.  

I saw the B2279 ST60A2G0 Circular Patch antenna RF board listed on the attachment (ST60A2 product development kit list). How can i find more info about that ST60A2 development board? I want to know more about the circular antenna used in RF board & spec before purchase. Thank you 

I am making a game console on the aforementioned board. The game is loaded from an SD card and runs in user mode. As such I have a couple of system calls which allows the game to work properly. The game in question is already done, now I am just working on scaling it, since it operates on 256x160 resolution which is fairly small to see with naked eye. I would like to scale it to 768x480, or times 3 the original resolution. As such, I have this function which should scale the content using DMA2D. The code example is down below.    extern DMA2D_HandleTypeDef hdma2d; void dma2d_scale_image(uint32_t src, uint32_t mid, uint32_t dst, uint32_t w, uint32_t h, uint8_t scaling_factor) { uint32_t dstW = w * scaling_factor, dstH = h * scaling_factor; /* columns */ hdma2d.Instance->FGOR = w - 1; hdma2d.Instance->OOR = dstW - 1; for (int i=0; i<dstW; i++) { volatile uint32_t s = src + (i/scaling_factor) * 4; HAL_StatusTypeDef status = HAL_DMA2D_Start(&hdma

Hi, We use custom carrier board and ST33TPHF20SPI in our products. We need help with Linux driver (kernel < 6.0) and integration help. We only found instructions for Pi boards.   Thanks   

Hi, I followed the instructions for installing the tpm_tis_spi driver for linux. (https://www.st.com/resource/en/application_note/an5714-integrating-the-stsafetpm-trusted-platform-modules-with-linux-stmicroelectronics.pdf)   I built and load the kernel modules: tpm_tis_core and tpm_tis_spi. from dmesg: tpm_tis_spi: probe of spi0.0 failed with error -110   For some reason the TPM isn't responding to our spi communication. How can I debug it?   Thanks

I have an STM32H735G-DK and a sample CAN application that is working fine.  I am now trying to use the CANFD ROM bootloader in system memory but cannot get any response from it. All the jumpers and solder bridges on the DK are at their default configuration.I have a Waveshare dual CANFD hat for a raspberry pi connected to the FDCAN1 pins (CN18). My test application works great with this setup, I can send and receive both CAN and CANFD messages all day long without issue. I am absolutely confident that there is no hardware issue at play here because the same hardware with my CAN application running in Flash works. Tested with bitrates from 125k to 1M, and CANFD data switching to 4M.I have set the boot switch (SW1) from the normal "0 - Flash" to "1 - SYS MEM", and looking at both AN2606 as well as AN5405, it looks like I should be able to set the CAN bitrate to 500kbps and issue a standard CAN message with ID=0x0 to get a response (Section 3.1 in AN5405).I do note that Section 2 sta

Hi STM community, I'm a fairly new user of the STMcubeMX software. I followed this tutorial (https://youtu.be/grgNXdkmzzQ?si=gDybMlGQxgTNwpPC) and every time I try to analyse my model under the 'MCU/MPU Filters' tab it just stays greyed out and does not analyse/generate anything or give me any notification.  I'm working with an STM32F746G-Disco to learn model integration and eventually implement my own onto the board.Any help would be greatly appreciated. Thank you! 

I want to create a scrollWheel that has 3 preset options.  Option A, Option B,  and Option A&BThe issue I have is that I can never get itemIndex  = 1 in scrollWheelUpdateItem callback , only index 0 and 2.  Also, after I first change wheel, it takes a while to be able to change it again.I tried to provide all the relevant code and touchgfx setup.  Appreciate if you can tell me what is incorrect. Here is my Container  (MenuItem):Here is how I set up my text:scrollWheel: Here is Container MenuItem.cpp:#include <gui/containers/MenuItem.hpp> #include <texts/TextKeysAndLanguages.hpp> #include <BitmapDatabase.hpp> MenuItem::MenuItem() { } void MenuItem::initialize() { MenuItemBase::initialize(); } void MenuItem::setWheelElements(int item) { switch (item) { case 0: text.invalidate(); text.setTypedText(TypedText(T_S1)); break; case 1: text.invalidate(); text.setTypedText(TypedText(T_S2)); break; ca

Hello STM, I'm working on a project using the STM32H7R3L8H6H MCU with a PSRAM chip connected via HEXASPI to XSPM1. I'm encountering massive issues with the PSRAM initialization, which I described in a different post. I found a discrepancy between the RM0477 Reference manual documentation and the STM32CubeProgrammer during my tests.  The XSPI_TCR register is described like this in the RM0477: If I open the STM32CubeProgrammer register window, I find a DHQC flag on the register bit 28 position. This bit is set to 1 all the time, and I have no information about its meaning. Can someone please explain the function of this flag? The STM32H7Rx/7Sx Arm®-based 32-bit MCUs are somewhat complex devices, and one would expect an actual reference manual. This isn't just some kind of "typo" in the documentation; it's another flag that probably has some functionality attached to it.     Be vigilant and always remember: "Always be yourself. Unless you can be a pirate. Then a

  Hello ST Team, We have integrated the TOF sensor into our hardware, and we would like to clarify the following: How can we calibrate the TOF sensor? When does the calibration occur—during device power-on or reboot? What are the results of the TOF sensor calibration? Thank you for your assistance!

I tried flashing a project created for the STM32H745I-DISCO board in CubeMx. I configured clock speed for the M7 core to 480MHz and the M4 core speed to 240MHz. After flashing, if i disconnect the board, the deadlock occurs. Then i have to pull up the boot0 pin and erase full memory in-order to get out of deadlock. Even then, if i disconnect again after flashing the problem repeats.If my clock frequency is less than 400, It is working fine. I guess it is the problem of power supply selection. Anyone has solution? Thanks.

Hello,I implemented a virtual com port using the usbx stack for the stm32U575 in standalone mode and it basicaly works.My problem is that I just can't put more than 8 bytes in the TX buffer at the time. If I do the program gets stuck (in the main loop)I tried both: ux_device_class_cdc_acm_write_with_callback and ux_device_class_cdc_acm_write_runbut they only work when the buffer length is less than 8 bytes.I have the following code in app_usbx_device.c: /* USER CODE BEGIN MX_USBX_Device_Init1 */ /* Initialize the USB Peripheral */ MX_USB_OTG_FS_PCD_Init(); HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_FS, 0x80); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 0, USBD_MAX_EP0_SIZE / 4); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 1, USBD_CDCACM_EPIN_FS_MPS / 4); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 2, USBD_CDCACM_EPINCMD_FS_MPS / 4); /* Link the USB drivers with the USBX DCD and check if it return error */ if(ux_dcd_stm32_initialize((ULONG)USB_OTG_FS, (ULONG)&hpcd_USB_OTG_FS) !

Hi, Are you able to identify the below products from their product markings?  I believe they should both be the LIS344ALH but one of them is behaving strangely. The 34AH marked product is reading 1g (2.332V) in the z axis when placed flat on a desk. The ones with markings 34AL are reading 0.7g (2.117V) when in the same position. I have switched the ICs around to rule out a PCB fault, but the difference always follows the IC, suggesting there is a difference between the AL and AH marking. I can't find any details on the datasheet outlining product markings to understand the codes printed on top of the IC.   Thanks Matt
