HiI'm implemented the most simple pwm generation and using interruptions in F401RE with TIM1. But a delay has been in the PWM generation and the update event interrupt (underflow and overflow) the most large pulse is the PWM and the another the when interrupt occours. I tested in diferent frequencys and in another timer and the error persists.Above has my code, i want centralize the interruption in the middle of pwm pulse.Thanks.

STM32CubeIDE 1.12STM32G0B0RE microWe have an older Cube project from a STM32F0 series that needs to be changed to the larger STM32G0B0 chip. We thought that we would just create a new project with the new micro and port in the older code. When we create the new project there does not appear anywhere in the selection process to have it use the Low Level drivers instead of the HAL.Start New STM32 ProjectUnder MCU/MPU selector, Select STM32G0B0RET6Nothing in this tab has anything to do with LL drivers.Select Next.Name Project, C++ Target Language and STM23Cube Project Type.Select Next.Select 1.6.1 Firmware package.Code Generation Options does not show anything about HAL or LL drivers.Select Finish.A project has been created where the Drivers directoy has a STM32G0xx_HAL_Drivers directory. Is there any way to have project creation use Low Level Drivers?Thanks.

Hello Dear all, I want to run my STM32L452ret6 with 1.8V and use SDMMC1 module. I can use SDMMC1 with 3.3V and 50k pull ups without problems, but when I run the MCU with 1.8V and use TXB0104RGY for shifting voltaghe to 3.3 it dose not work as expected.  Which component to use for shifting SDMMC1 signals from 1.8V to 3.3V? Can I set pull up resistors with 50k valu to 3.3V but run 1.8V from mcu ? Regards, Hakob

Hi,The ADC test has only 2 channels: Vrefint and TempSensor. The following ADC result (convertedData) is read out through DMA:tick = 1s - convertedData[0] = 113968573 convertedData[1] = 0 tick = 2s - convertedData[0] = 113837503 convertedData[1] = 0 tick = 3s - convertedData[0] = 96339657 convertedData[1] = 0 tick = 4s - convertedData[0] = 113837502 convertedData[1] = 0 tick = 5s - convertedData[0] = 113837503 convertedData[1] = 0 tick = 6s - convertedData[0] = 96405193 convertedData[1] = 0 tick = 7s - convertedData[0] = 113837503 convertedData[1] = 0 tick = 8s - convertedData[0] = 113837502 convertedData[1] = 0 tick = 9s - convertedData[0] = 96405192 convertedData[1] = 0  Where convertedData[0] is the ADC reading of Vrefint which should be 4095, the other is that of TempSensor which should not be 0.The ADC configuration:The code: /* USER CODE BEGIN 2 */ HAL_ADCEx_Calibration_Start(&hadc1); HAL_ADC_Start_DMA(&hadc1, convertedData, 2); HAL_Delay(1); startTic

Hello to everyone,I have crereated my own STM32L452 board with battery power supply.It dosent run as expected. Sometimes I need to discharge caps and sometimes this is not helping. When it works and I connect nreset to groung and release it stops working, I need to powewr off and repeat mentioned process. I can flashe the code but have a problem with online debbuging (ususaly I louse connection). Somtimes it stops working when the process reaches to delays. When it works in DP port voltaghe level is low and when it not working this pin is high. I have disconnected NRESET pin from board and this is not helping.I have attaced the footprint of my board (mcu part).What to do ?

Hello!I have never used a Jetson Nano before and am rather unfamiliar with lower level programming. I have a VL53L4CX attached to the correct Jetson nano pins and can see the device when I run i2cdetect -r -y 1 at address 0x29. My question is whats next. I've done a lot of research online and have no idea how to incorporate this into an actual program that reads the distance detected by the sensor. The goal of the project is to attach 8 of these sensors to a MUX and then get data from all of them by changing i2c ports. I have seen posts referring to the linux driver, which I have downloaded but don't know how to install or use. I have a python program that sends bytes over i2c, is it as simple as sending a specific message over i2c and then reading a response? If so, what is that message?

Hi, is there support of azure rtos for stm32h5 devices?I am looking for a MCU with ethernet and azure rtos support. I have fond some examples for sym32h7 devices but those are too big. Smallest is 100pins and they are more expensive. The smallest and cheapest seems to be stm32h5 series, but when I open package manager in cube ide X-CUBE-AZURE-H5 is not there.Is it not supported or I am missing something? 

Hello, I'd like to inquire if the STM32H735G-DK supports a CAN FD transceiver, or if I should purchase an external transceiver

Hello,Can I only write to the flash with 64 bit variables, or also 32/16/8 bit?I just used this function for this: HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, activepageaddress + u32_Offset, u64_Data)I have an STM32L432 uC.I already found this example: https://github.com/STMicroelectronics/STM32CubeL4/blob/master/Projects/NUCLEO-L4P5ZG/Examples/FLASH/FLASH_FastProgram/Src/main.cMany thanks in advance.

Hello,I'm using NUCLEO-G474RE kit with soldered USB on PINs:PA11 - USB Data minusPA12 - USB Data plusVIN - VBUSIn the User configuration I have:nSWBOOT = CheckednBOOT0 = CheckednBOOT1 = CheckedThere is programmed program with blinking LED so I know it is running. The BOOT0 on board is connected after reset or power up.Unfortunately the bootloader never start and the board is blinking with my program instead. Can you please help what could be wrong so the bootloader doesnt start?Does the bootloader recognize if there is USB connected automatically? Thank you. Jan     

Paragraph 10.7.3 of RM0456 manual for STM32U575/585 microcontroller cites registers RCC_AHB3AMENR and RCC_APB3AMENR to configure autonomous peripheral clock gating during stop 2 mode.However, I didn't find any other reference of such registers in the same document nor in the datasheet. Instead, it seems that such function is already covered by RCC_xxxxSMENR registers. May this be a typo? Thank you for the excellent workRegards

Hi, I have TouchGFX Designer 4.22.0 version installed in my PC. For my project I am using STM32U5A9NJH6Q  controller with Riverdi display part number SM-RVT50HQSNWC00-B. But, in the TouchGFX Designer application I am not able to create a project because in create->By Partners i am not able to find a template for this particular display. I can only find the templae for 1280*800 and 1024*600 resolution displays for Riverdi. But not for 800*480 resolution.  Can any one please have a look in this and help me fix this issue. I have also attached in the screenshot of how my designer application create window looks.

AS  in the  TUTORIAL  FDCAN NORMAL OPERATING MODE , What pin on the NUCLEO H743ZI2 -144 board  receives the VVD  ( and  VIO ) from the Transceiver MCP2526FD 8DIP  see attached  Is it a plug in or do I need to create a contact pt . 

I need help with configuring HYPERRAM for my STM32 on a custom PCB. The HYPERRAM pins are about 32mm away from the MCU pins.The HYPERRAM works, but I get strange flickering on the display even with static data in RAM which I think comes memory errors of the external RAM. My memory passes some basic memory tests, but I think things go wrong when the LTDC peripheral reads from the memory at high speeds. I could be wrong about this, but I need to tune the configuration of the memory anyway. I want to exclude this possibility.There are so many settings and contradictory advice that I'm overwhelmed.Turning on D-cache for the HYPERRAM doesn't help.If I calibrate the delay block the memory tests fail. If I don't calibrate it, it doesn't fail. If I disable it it also fails.I've implemented calibration according to the following forum post: https://community.st.com/t5/stm32-mcus-products/stm32h7-octospi-mode-hyperbus-hyperram-access-and-delay-block/m-p/143244/highlight/true#M27659I can read the

Hı everyoneI was trying to send the data to termite terminal. The data variables are coming from DS1307 (RTC Module) and BH1750 (Lux) sensor. However, The data coming from lux sensor is zero in termite. Rtc module variable is okey. Lux sensor variable is declared as lux. When ı debuged it, ı can see lux value properly but the USART transmit 0. By the way, both of sensor is connected to I2C1 bus. I have Stm32f4 discovery kit. How can ı solve that ? /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "main.h" #include "DS1307.h" #include "bh1750.h" #include <stdio.h> #include <string.h> /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ char tx_buff[50]; uint16_t lux=0; /* USER CODE END Includes */ /* Private typedef -----------------------------------------------------------*/ /* USER CODE BEGIN PTD */ /* USER CODE END PTD */ /* Private defi

Hello,I have a interrupt conflict between two peripherals on pins PK7 and PI7. I am aware that these two end up on same EXTI7 interrupt mux, hence conflict in interrupt occurs. I am wondering if there is a way to separate these interrupts on different controllers perhaps? Re-designing the HW is not really possible or very hard at this stage 

Hello,I would like to determine the ADC sampling frequency.I am initializing the ADC with following: hadc1.Instance = ADC1;hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4;hadc1.Init.Resolution = ADC_RESOLUTION_12B;hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE;hadc1.Init.ContinuousConvMode = ENABLE;hadc1.Init.DiscontinuousConvMode = DISABLE;hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;hadc1.Init.ExternalTrigConv = ADC_SOFTWARE_START;hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT;hadc1.Init.NbrOfConversion = 2;hadc1.Init.DMAContinuousRequests = DISABLE;hadc1.Init.EOCSelection = ADC_EOC_SEQ_CONV;if (HAL_ADC_Init(&hadc1) != HAL_OK){Error_Handler();} /** Configure for the selected ADC regular channel its corresponding rank in the sequencer and its sample time.*/sConfig.Channel = ADC_CHANNEL_0;sConfig.Rank = ADC_REGULAR_RANK_1;sConfig.SamplingTime = ADC_SAMPLETIME_112CYCLES;//ADC_SAMPLETIME_3CYCLES;if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK){E

The target MCU on the NUCLEO-F446RE board receives its clock input directly from the on-board STLink-V2.1 probe (see clock signal MCO in figure below):That's because the crystal X3 is not soldered on the board by default. So, when I launch a new project in CubeMX for this particular board, I would expect to see this reflected in the clock settings:However, I see the following: That's weird. The default selection is 'Crystal/Ceramic Resonator' while in fact, no high-speed crystal is soldered on the board.Is this an error in CubeMX? If so, then the following .ioc file must be fixed:C:/Program Files/STMicroelectronics/STM32Cube/STM32CubeMX/db/plugins/boardmanager/boards/A42_Nucleo_NUCLEO-F446RE_STM32F446RE_Board_AllConfig.ioc
