Hi.I am absolute noob with stm32 and i am currently trying to connect GY-GPS6MV2 module to RobotDyn STM32 Mini(STM32F103C8T6).  I have connected GPS module to pins and set up USART1 in asyncronous mode. I have done everethyng according to official example on how to work with USART1 using DMA. In the interrupt handler i wrote small piece of code to copy data from rx buffer to linked list. But from here things have gone really weird, because in the debugger i see, that my global variable(nmea_head, this is first node in linked list) is allocated in the same memory area where irq handler stack resides(See attached screenshots). What am i doing wrong?Here you can see, that SP for HAL_UART_RxCpltCallback is at 0x20000104This is definition of global variable nmea_head. On the right side you can see, that it was placed on the address 0x20000110. This address overlaps with stack frame of HAL_UART_RxCpltCallback, so my variable gets corrupted. What am i doing wrong?This  happens prior

I built the root file system using 'build root', which previously automatically loaded 'galcore. ko' when the system started. But today I accidentally reset the configuration of 'build root', and since booting up, this module has been unable to load automatically. It needs to be manually loaded every time. Does anyone know which configuration affects its automatic loading?

i have program like this and from the program i have the output like this (picture) and i used the potentiometer to find the value is AD_RES_BUFFER: the potition of picture is disable of DMA Countinous Request ADC ANALOGbut the potentiometer work (produces value ) if i enable the 'DMA Countinous Request' in stm32cubeMX i used the nucleof334r8  but the value of b and output is 0 (zonk).and if i disable the 'DMA Countinous Request' in stm32cubeMX the potentiometer doesn't work (produces no value if rotated) and only displays value randomly and i dont know from where the value, but i have a value of 'output, b' in watch 1.so i want to enable the 'DMA Countinous Request' and get the value of potentiometer (REAL TIME AND UPDATE ID I ROTATED THE POTENTIO) but i dont know how to set it in cubeMX and prgram the keil.PLEASE ANYONE HELP ME. 

We are using LORAWAN with STM WL series Microcontroller.For that we have used predefined method of getting readily code of both the functionality.I have shared that link below.https://docs.rakwireless.com/Product-Categories/WisDuo/RAK3172-Module/Low-Level-Development/#rak3172-on-stm32cubeide-with-stm32wl-sdk-v1-2-0After using above document we are able to get code with 0 errors and 0 warnings.But when we open .ioc file and update something. It will change so many files and due to that we are not able to build the code succefully. Any one have solution regarding the same?How can I easily integrate any module (Like ADC, Timer, etc)RegardsManan

As screen output from STM32CubeIDE version 1.16.0, is this latest chip version of STM32WLE5JCI6TR?Please point to web links on datasheet and errata (workaround and chip deviation from datasheet error).  Best regards

Hi,I am using VL53L4CX sensors with a custom-made board which uses the STMH755ZI. I am using the library provided by STM to get the sensor measurements.Initially, my tests were done using a Teensy 4.0. At that point, I noticed that a single VL53L4CX sensor takes around 3ms to get data through I2C when using the VL53L4CX library. However, when I switched to the VL54L4CD library, it was much faster, taking around 0.5ms per sensor. This includes all the data that the sensor provides.After that, I moved to the STMH755ZI. Since this is an STM chip, I thought it might be more compatible and faster compared to the Teensy, as the TOF sensor is also made by STM. Contrary to my expectations, the time it takes to read one sensor significantly increased. Using the VL53L4CX library, it takes around 10-11ms to read data for a single sensor. Then I tried the VL53L4CD library and was able to reduce the time to 1ms per sensor.I am working on a project with strict time constraints, so I commented out re

Hi, I am interested in creating a similar PCB to the SMARTAG1 but without a battery to reduce the size of the board. Is it possible to program and power the board purely through the SWD connector?

Good Evening Sir/Mam, I want to download the- STM32CubeU5 software in my PC(Laptop). I have downloaded the Software and its Patch from this official website. Both these Files were downloaded succesfully in Zip format.  Sir/Mam, it would be very helpful if you could please guide me through- How to Install and Launch the Software and all related Packages in my system from those downloaded Files from the website or provide any Tutorial Videos for the same.  Thanking You, ANKUR.

I have an STM32G4 board that is to function as a virtual COM port via USB.  This is my first attempt at implementing USB. Within CubeIDE, I enabled the USB feature and configured a middleware device for the virtual COM port. I’m not seeing the PC react in any way when I connect the board. I’m not sure where to begin to debug and I don't see any examples for the STM32G, so I'm also not sure if I've completed all the needed steps for it show up as a PC device.Can I observe connection progress with the PC via the USB registers? If I had an electrical failure on the USB connection, what diagnostics could I run in software from the PC?

Hi All,  I have a circuit that works very well and uses the BTA24-800CWRG device housed in a TO-220 through-hole part. I currently have it bolted to a large enough heatsink and a fan above it just for safety and to keep it cool. I am now updating the design and would like to miniaturize the circuit. I am looking at this ST part: T3035H-6G-TR. This is a surface mount version and I would prefer to use this instead of a large heatsink on the board. I use the TRIAC in a pulse-skipping circuit to control a 120V 10A heating element. I developed a circuit to sense the zero cross and fire the TRIAC based on temperature and feedback through PID control. The TRIAC turns on during a percentage of multiples of the AC sine wave and stays on until the sine wave reaches the zero cross where the TRIAC turns off. Hard to explain but I hope you get the idea. My question is, can I use a surface mount TRIAC for this particular application? Since it is essentially switching does the TRIAC ge

I have a program that displays the current temperature of a room on the UART terminal and I want to start getting into the habit of separating my functions into their own source and header files, however, I'm running into a couple of problems. Here is my main header file: #include "main.h" //Main header file #include <stdio.h> //Standard header filer #include <string.h> //String header filer #include "uart.h" #define SI7021_ADDRESS_READ (0x40 << 1) | 0x01 #define SI7021_ADDRESS_WRITE (0x40 << 1) #define SI7021_MEASURE_HUM_NOHOLD 0xF5 #define SI7021_MEASURE_TEMP_NOHOLD 0xF3 char msg[50]; I2C_HandleTypeDef hi2c1; UART_HandleTypeDef huart2; void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_I2C1_Init(void); static void MX_USART2_UART_Init(void); static uint32_t si7021_measure_humidity(I2C_HandleTypeDef *hi2c) { uint8_t si7021_buf[4]; si7021_buf[0] = SI7021_MEASURE_HUM_NOHOLD; // Start measure int res = HAL_I

I am trying to read data from an MPU6050 sensor using I2C with the STM32F413ZH board. However, I am encountering errors, likely because the levels of the SCL and SDA initialization and termination bits are incorrect. This causes the system to sometimes work correctly and other times result in errors. When the HAL_I2C_IsDeviceReady function returns an error value, I tried to deinitialize and reinitialize the I2C unit, but it did not work. Upon investigating the error, I found that it returns HAL_BUSY and enters the I2C_WaitOnFlagUntilTimeout function, where the I2C error code indicates a timeout issue. Specifically, in these sections:  if (hi2c->State == HAL_I2C_STATE_READY) { /* Wait until BUSY flag is reset */ if (I2C_WaitOnFlagUntilTimeout(hi2c, I2C_FLAG_BUSY, SET, I2C_TIMEOUT_BUSY_FLAG, tickstart) != HAL_OK) { return HAL_BUSY; }   while (__HAL_I2C_GET_FLAG(hi2c, Flag) == Status) { /* Check for the Timeout */ if (Timeout != HAL_MAX_DELAY) { if (

Problem : GPIO PB7,8 is pull up in reset state.Reproduction: After Clearing Reset  (Reset Goes low)  the voltage on PB7 and PB8 goes high. uc is erased. We have external pull down connected to those pins (100k), but the signal stays at 2.5V Could you confirm that pull-up in reset mode on those pins is correct behavior?  I suspected that GPIO should go to input mode and pull down pull up should be disabled.     

Hi all.I'm working through the lab material for the STM32MP1 workshop and have run into a snag after following the "extra hands on" presentation "Lab-MP15_FromPartNumber_To_BasicDeviceTree_with_CubeMx.pdf". My high level goal is to get binaries (TF-A, FIP) to enable production eMMC programming via USB DFU.While we've got working eMMC images produced by buildroot (based on an earlier version of the ecosystem) we've discovered that the versions of the boot chain we're using don't support USB DFU (specifically TF-A).To remedy I've gone through the lab materials and Cube MX for ecosystem 5 along with modifications for our custom board and have the resulting input DTS files for building the boot chain binaries:├── kernel│   └── stm32mp153c-som-dfu-mx.dts├── optee-os│   └── stm32mp153c-som-dfu-mx.dts├── tf-a│   ├── stm32mp15-mx.dtsi│   ├── stm32mp153c-som-dfu-mx-fw-config.dts│   └── stm32mp153c-som-dfu-mx.dts└── u-boot    ├── stm32m

HiI am having trouble doing anything useful with the STM32WB5MMG discovery board using version 1.16.0 (Windows) of STM32CubeIDE. I started off with a new application based on the this above board and I don't see anything useful related to the devices that on the board such as the RGB LED, TOF sensor etc? If I created a template APP for this board, surely it should all be configured already?Other things don't seem to be correct either such as I2C3 which I believe is the main bus used for some of the external devices such as the accelerometer etc doesn't seem to be enabled when I run up the .ioc file and look at the configuration. Also here (in what was cubemx) I can see some other potential useful extra software components (which I guess have come from the SDK specific to this board) such as TOF and DISPLAY. The TOF component I can add but I'm not sure whether it is working because I haven't been able to verify any debug output. There is a virtual COM port on my PC but I don't see

It looped at a location deprived of access, waited a second, and returned to the same action. I thought STM32 was about programming.

Hello, I'm using the STM32F413ZH board to read data from the MPU6050. While the data retrieval works when I implement it in a blank project, it fails to function correctly in my current project. This project also includes two additional UART interrupts, though they are not currently connected to the system. What might be causing the issue?In this project, HAL_StatusTypeDef always returns HAL_BUSYThank You.  #include "main.h" #include "string.h" #define MAX_NMEA_PROTOCOL_CHARACTER_LENGTH_ 82 I2C_HandleTypeDef hi2c1; UART_HandleTypeDef huart4; UART_HandleTypeDef huart5; UART_HandleTypeDef huart3; PCD_HandleTypeDef hpcd_USB_OTG_FS; void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_USART3_UART_Init(void); static void MX_USB_OTG_FS_PCD_Init(void); static void MX_UART4_Init(void); static void MX_UART5_Init(void); static void MX_I2C1_Init(void); HAL_StatusTypeDef hal_status_one; //THIS CODE FOR I2C uint8_t data_mpu[1] = {0x00}; //THIS CODE FOR I2C

Please could I have help identifying the component in the attached image to find a suitable replacement as it is shorted. Many thanks, Jazz.

I am using a STM32L431KCU6 microcontroller and reading data from I2C every 90ms. I would like to implement a sleep mode to achieve lower power consumption, I am using timer6 which generates an interrupt every1ms for system run time. I was thinking I can change the timer period to be 90ms prior to put the device on sleep and when TIM6 interrupt happens (wake up the processor) I can change the period to 1ms for normal operation.  is this possible? and how can I achieve this? I don't have any experience in using sleep mode but I have been reading similar questions and I've seen WFI coming up very frequently.  Is there any example codes available? or documentation which can assist in writing code?  Thanks in advance and appreciate any help. Kind RegardsManpreet Singh

Hello everyone,We have a custom board based on stm32mp157c. We have a working bsp, which have tf-a 2.2 and u-boot 2020 version. Currently we are updating tf-a to 2.6 and u-boot to 2022.

I updated the STM32CubeProgrammer from version V2.10 to version 2.17, but it doesn't work on my computer (Windows 7 ). I installed new version on Java, reinstalled program, it didn't help.    

While looking at the stm32h745xihx-pinctrl.dtsi file I see the slew rate is defined for the QUADSPI pins, but the LTDC pins. Is it set to Very High speed implicitly? I would be concerned if they are set to Low Speed by default. Thanks in advance for any input.
