Hi there!here i'm for ask another help. I use STM32G031 for write and read eeprom 24LC01B , and i work with where Address = 0x01;HAL_I2C_Mem_Write(hi2c, DevAddress, Address , I2C_MEMADD_SIZE_8BIT, &val, 1, 100);so if i wrote 7 byte everythingh work perfect if i wrote 8 byte ti find the last byte in the position 0x00 in my eeprom why ? if i change eeprom like 24lc256 and I2C_MEMADD_SIZE_16BIT HAL_I2C_Mem_Write(hi2c, DevAddress, Address , I2C_MEMADD_SIZE_16BIT, &val, 1, 100); everythingh work perfect please can you help me ? Thanks Sergiio 

Hello,we have CubeIDE 1.8 with GCC 12.3 and for a certain project want to turn the toolchain back to GCC 10.3. We successfully installed it via Toolchain Manager and switched to it in Project - Properties -> C/C++ Build - Settings - MCUToolchain . But when compiling we get an eror message that the prefix to build the compiler instructions is empty and in Project - Properties -> C/C++ Build - Settings - MCU Settings the MCU field suddenly is empty.The only way back is to change back to GCC12.3 and restart CubeIDE. Then we are back at where we started.What's wrong? Is that known? How to fix it?Thanks for any helpMartin

I am designing interface board  similar to MB1835 for our touchscreen to work with MB1829.  STM32U5G9NJH6Q power supply VDD, VDDA, VDDIO and VDDUSB are all supplied with 1.8V. Thus, STM32U5G9NJH6Q GPIO is compatible with 1.8V signals. Touch Screen connects to MB1835 also has signal levels of 1.8V. i.e.  I2C_SCL,  I2C_SDA, Screen_int, screen_resetn are of signal level 1.8V. Yet, all these signals are designed to use level shifter on MB1835. May I know why?  And for our customized interface board, may touchscreen with 1.8V  signals interface with STM32U5G9NJH6Q GPIO directly? Thank you.Kelly

Hello,I'm working on a project where I'm using an STM32H7R3L8H6H and an MX25UW25645G. It isn't possible to get the Flash working on XSPI2 when using the ExtMemLoader generated by STM32CubeMX. I checked the example in the firmware package and found the following errors in it:In the STM32CubeMX XSPI2 configuration, "Parameter Settings" is the "Memory Size" with 32GBit selected.The "__FLASH_SIZE" in the linker file "STM32H7S3L8HX_ROMxspi2_app.ld" is set to 0x08000000.Since the NUCLEO_STM32H7S3L8 board is using the MX25UW25645G chip, those settings are incorrect.They should be 256GBit instead of 32GBit and 0x02000000 instead of 008000000.Where can I find the source code for the "MX25UW25645G_NUCLEO-H7S3L8.stldr" which is shipped with the STM32CubeProgrammer? It looks like this loader is working, but I want to use my own loader for my project. Unfortunately, there is not one working example anywhere that uses the MX25UW25645G, even if this chip is used by STM on their NUCLEO board. It

I'm using the NUCLEO-H7S3L8 and the max CPU frequency is 600MHz. By default, CubeMX sets VOS is set to 0 (low).But if this were the case, wouldn't it be violating the datasheet where it states 400MHz is the max CPU clock? I've been using 600MHz clock without ever setting VOS high and I haven't gotten any issues, so I'm not sure whether or not it's fine to leave VOS alone.

Hello.I have designed my own STM32H747IGT6 board.And I created a simple project with STM32CubeIDE to confirm its operation.In this project, CM7 is a program that simply blinks the LED in a while loop. (CM4 is just code generation)  while (1) { HAL_GPIO_TogglePin(GPIOE,GPIO_PIN_9); HAL_Delay(200); /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */ } However, when I debug the M7, the code stops at this point and I can't continue.  /* Wait until CPU2 boots and enters in stop mode or timeout*/ timeout = 0xFFFF; while((__HAL_RCC_GET_FLAG(RCC_FLAG_D2CKRDY) != RESET) && (timeout-- > 0)); if ( timeout < 0 ) { Error_Handler(); } This is obviously happening because CM4 is not running.So I checked this link and changed the run configuration and debug configuration for CM7 and CM4, but it still stuck at the same point.Also, after reading AN5286, I checked the addresses of CM7 and CM4 in STM32CubeProgrammer, but they were the sa

Originally tagged-on to this old thread. Split to new thread for better visibility.Hello,I seem to have a similar problem, besides, that DMA is disabled.I have an STM32H503RB (NUCLEO-H503RB) trying to read out some I2C slave devices. It actually works only for one of the devices. This tells me, that the I2C bus is somehow working correctly.But for the remaining three IC (Temperature, GPIO & ADC), there is no way for me to even send the register address.Right after the Device address, the communication ends. See the attached file. This is the communication to an MCP9801T temperature sensor (device address [W] = 0x92).I actually don't understand the reason, why this happens.f=100kHzWhat I did:- changing pull-ups: same behaviour for 4.7kOhm & 3.0 kOhm- soldering the device on an otherwise empty PCB: only the 100nF, the pull-ups and the MCP9801T is there.- I2C-Deinit as well as I2C-Init.The source code is as simple as that:   while (1) { data[0]=0x00; data[1]=0x01;

Hi ST Community,I am an iOS developer exploring communication with your ST25 NFC products. However, I couldn’t find any binary library like a .framework or Swift Package that can be easily integrated into our project.We have attempted to work with the source code provided iOS app for ST25DV-I2C PHDC demo, but we’ve encountered some challenges getting it up and running. Before investing a significant amount of time troubleshooting, I wanted to ask:Does a pre-built binary library or an official Swift Package for iOS exist that we can use to simplify integration?Thank you for your help!Best regards,CanniPriest

Hi,I am working on STM32G491KCU6 board.We are connecting STM to a linux based SoC via SPI. What we required is, we need to flash STM from SoC. We found stmflash binary which supports only through i2c and UART. Is there any tool that support flashing via SPI?

Hello, We are considering using the ST33TPHF2XI2 for our application. The datasheet mentions two variants:ST33HTPH2X32AHE1ST33HTPH2X32AHD5Could you please recommend which device would be more suitable for a new design, considering stock availability and long-term perspective?Please provide your input.Thanks,Sonali Z 

There is a problem about PLL3 while using engineering mode on STM32MP157A-DK1 board. By STM32CubeMX, I configed the clock of M4 core, using PLL3P to get 209MHz, generated code, rebuild it and entered the debug mode. But it shut down and get into an Error. I debuged it bt step, found that it failed in the intial function HAL_StatusTypeDef HAL_RCC_OscConfig(RCC_OscInitTypeDef *RCC_OscInitStruct). When it get to configure PLL3, failed and enter the error. So what I missed? May someone can help me. Thanks! 

Hi, STM32WL33 is part of 6LoWPAN products, but in Firmware package there are no examples for 6LoWPAN. Can someone explain how to incorporate 6LoWPAN in STM32WL33 series ?

resource: https://github.com/ArduCAM/Arducam_MegaI need to integrate Arducam camera using STM32L4xx, but i cannot found the library, the resource i was found is using SPL instead of HAL. Someone please help me to resolve this issue 

I'm using  STM32G030F6 chip.  Try configure on pin PA8 external interrupt. When it make in UI "PInout & Configuration" tab it works as expected. But I want configure it from code. Here example: Added to main.h pin naming  #define FC_ON_Pin GPIO_PIN_8 #define FC_ON_GPIO_Port GPIOA #define FC_ON_EXTI_IRQn EXTI4_15_IRQn function for pin setup  void FlyControler_Init(void){ #ifdef FC_PINIO GPIO_InitTypeDef GPIO_InitStruct = {0}; /*Configure GPIO pins : FC_ON_Pin */ GPIO_InitStruct.Pin = FC_ON_Pin; GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING; GPIO_InitStruct.Pull = GPIO_PULLUP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(FC_ON_GPIO_Port, &GPIO_InitStruct); #endif } After call this function interrupt is not triggered.What I do wrong?

Hi, I have enabled the HASH, RNG, and PKA. I also enabled the Global Trust Zone Controller and configured the PKA as privilege access. However, the generated code from STM32CubeMX does produce an error due to undefined GTZC_CFGR3_PKA_Pos which is missing from stm32h523xx.h Is that an error?  I have to mention that when I first created the project, I haven't check Trust Zone option under the project. But I later enabled the GTZC.Kind Regards,Hani

Hi Peter, Thanks for replying, i have another need verity the marking, kindly check the photos of product below is for part# M95040-DRDW3TP/K ?   Part# M95040-DRDW3TP/K

Refer to datasheet DS12288 Rev 6(STM32G474xB STM32G474xC STM32G474xE), where Table 5 (Temperature sensor calibration values) describes that the high temperature calibration sampling point used for internal temperature sensor calibration is 130 degrees Celsius, but in the LL library, 110 degrees Celsius is used for temperature conversion.stm32g4xx_ll_adc.h: line 386 #define TEMPSENSOR_CAL2_TEMP (110L) /* Temperature at which temperature sensor has been calibrated in production for data into TEMPSENSOR_CAL2_ADDR (tolerance: +-5 DegC) (unit: DegC). */ Which one is correct?

There are two motors, a large motor （Motor1）driven by discrete gate drivers and mosfets, and a small motor （Motor2）driven by the integrated driver L6230.For performance reasons, Motor1 needs a 3 sample resistor scheme (R3_2, ADC1+ADC2), so what current detection schemes can Motor2 have? Does it have to use ADC3 which is not used by motor1, but there seems to be no “r3_1_h7xx_pwm_curr_fdbk.h” in the MCSDK, does it mean that single ADC current sampling is not supported? I'm trying to customize a inverter with H755&Dual motors by STMC board Designer. With basic features loaded, the workbenck failed to generate files like: mc_task.c\stm32h7xx_mc_it.c\mc_parameters.c...Any suggestion? 

Hi, I have tried to configure the STM32H523RET6 for using USART1 with multiprocessor communication mode and enabled the auto baudrate detection. However, according to the application Note AN4908, the MCU stm32h523 doesn't support auto-baudrate. I don't know why STM32CubeMX has allowed me to enable/disable the auto-baudrate. Either the CubeMX has an error or the application note I am using CubeMX version 6.13.0 Regards,Hani

We have been running into an issue on brand new custom hardware with the STM32wb55 chip that when we perform a FUS and BLE stack update using the stm_programmer CLI tool we need to perform a full power removal and apply before the BLE stack will actually work. When we run our tools to provision a board after the wireless stack upgrade is done we gave it the start stack command and when we boot into our application the cpu2 is failing to init. To recover from this we need to completely remove power and re apply for it to work.Does the wireless stack upgrade require a full power cycle to complete.  We are using the command line tools connect under reset to try and trigger a reset of cpu2 but it does not.

I got a NUCLEO-H755ZI-Q board and downloaded all the docs and software (en.stm32cubeh7-v1-12-0.zip).When I go to C:\STM32Cube_FW_H7_V1.12.0\Projects\NUCLEO-H755ZI-Q, there’s just a read.me file that says: “All projects available under Projects\NUCLEO-H745ZI-Q are fully compatible with NUCLEO-H755ZI-Q board.”I follow the “C:/STM32Cube_FW_H7_V1.12.0/Projects/Archives/STM32CubeProjectsList.html” documentThe only device that’s close is the STM32H745ZI which I select. It then displays the alert “The device STM32H745ZI_CM7 is not recognized by TrueSTUDIO.”What component am I missing? Also, where's the STM32CubeMX file for the NUCLEO-H755ZI-Q board?

 To continue my studies, I need a Nucleo Board that has a µCU that is similar to the STM32H743ZIT6. Which would be the most suitable?

Hi all, I have a brand new B-WB1M-WPAN1 board which worked with the ST BLE Toolbox out of the box. It had 2 services, Heart Rate and LED. I was able to turn the LED on and off, notify the phone with the button and see heart rate. Imported into CubeMX the .ioc project "BLE_HR_p2pServer.ioc" from theSTM32Cube MCU Package for STM32WB series page (link below) and flashed to the board. I can still connect to the board and see the 2 services but the LED and notification button will not produce any actions. The heartrate also has no data. https://www.st.com/en/embedded-software/stm32cubewb.htmlAny ideas what to look for?Thanks

Hi I'm now using Teseo-VIC3DA through evb.I have a curiosity about which level the sensor fusion btw GNSS and IMU is performed.I can log the data through Teseo suite application.But i can't figure out that GNSS messages such as NMEA GNGGA, GPVTG etc... is the result of fusion or the raw data of GNSS.Those messages is the result of fusion btw GNSS and IMU?And if that data is the result of fusion, Is there any other way to get raw GNSS data?Thanks a lot in advance.
