Solved

Hello,I am trying to get a simple GPIO toggle working with the NUCLEO H743ZI board. I noticed that when I try using the GPIO port F pins, even though the port registers are configured correctly and I can see the bit changing in the GPIOF_ODR register. I do not see any coltage change on the pin. I tried the same code with other GPIO ports and it seems to be working fine. My GPIO config: (attached)My code :/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2021 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under BSD 3-Clause license, * the "License"; You may not use this file except in compliance with the * License.

Hi, Before posting this question, I did enough testing and understand the concept of certificate verification process. I am stuck with this issue since last one week and couldn't understand the associated route cause. Please help me resolve this issue. Requesting some ST core engineer to look into it.

I seem to be unable to get the RTC to start. I can set the time, and read from it, but it doesn't increment.I have tried using the external and internal oscillator, neither have been successful. Everything has been set up with CubeMx, and I have used the RTC before on an STM32L0 micro with no issue, comparing it to my old code I cant see what I am doing differently.I have attached the relevant parts of the code, if you know what I am missing please let me know.Thanks,Lukestatic void MX_RTC_Init(void) {   RTC_TimeTypeDef sTime; RTC_DateTypeDef sDate;   /**Initialize RTC Only */ hrtc.Instance = RTC; if(HAL_RTCEx_BKUPRead(&hrtc, RTC_BKP_DR0) != 0x32F2){ 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(__FILE__, __L

Hello!​Datasheet does not show VFBN connect to Vin and shows ADIM need to connect to LDO3 or resistor to gnd. However, eDesignSuite schematic shows that. I want to know why . Could you help me to figure out these design? Thank you~

Anyone Have Example code for STM32L496ZG Internal Flash read and Write

I'm currently evaluating several boards, but I'm having trouble downloading the application templates. The quoted error will appear sporadically through the download process... anywhere between 0% and 30% downloaded. My internet connection is definitely fine, we have not reported any issues there with other apps / browsers.Any idea what's happening?

The technical docs state that multipleication (MULS instruction) can take either 1 cycle or 32 cycles. This is defined when the board is produced. Does anyone know which of the two configurations the STM32F072RB uses?

Hi,I flashed OS "en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12.tar.xz" to board STM32MP157C-DK2. Then remove all the cable,and only remain a type C cable connected with my laptop Type C port.But the kit can't power on.Could you tell me how to let it to sink power as USB device,and source power as USB host?Thanks,QiZhang

My goal is to add i2c5 in the dts for userspace access however it is not visible at /sys/bus/i2c/devices. My steps are as follows:1) bitbake virtual/kernel -c devshell2) in new shell, modify the arch/arm/boot/dts/stm32mp157a-dk1.dts3) in new shell, make dtbs or make stm32mp157a-dk1.dtb, and close the new shell4) in original shell, bitbake virtual/kernel -f -c compile and bitbake virtual/kernel -f -c compile5) build-openstlinuxweston-stm32mp1/tmp-glibc/deploy/images/stm32mp1/scripts/create_sdcard_from_flashlayout.sh ../flashlayout_st-image-weston/trusted/FlashLayout_sdcard_stm32mp157a-dk1-trusted.tsv and create the .raw for dd to the sdcardHowever, with above steps seems the updated dtb file is not populated to the sdcard image. Am I missing some steps?

HiI'm using stm32f767 and want to use LTDC with double framebuffer.Can i do this with one sdram?LTDC is fetching data from sdram(front buffer) and i have to prepare the back buffer at the same time(load data from sdcard into sdram)Internal sram capacity is not sufficient.How can this happen?LTDC and SDRAM are working and i can display image through LTDC from SDRAMLTDC is running at 30MHz and SDRAM clock is 90MHz.

Hello,We are using LIS2DH12 sensor in our product. We are following the self test procedure mentioned in AN 5005 Section-12.We have confusion about how to use the raw data from OUT_L and OUT_H of each axis.(1) Do we need to convert raw data into gravity and then do average and difference or can we use raw data as is for average and difference ?(2) while device is in test mode, OUT_L and OUT_H are result of simulated force only or it can be sum of simulated force and external force ?Regards,khodidas

I've been assigning some of my storage areas into different memory areas as defined within the STM32H743ZITX_RAM.ld file in a project using STM32CubeIDE. This has first required me to insert the appropriate definitions where I've used memory domain D3 as an example:MEMORY { DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K RAM_D1 (xrw) : ORIGIN = 0x24000000, LENGTH = 512K RAM_D3 (xrw) : ORIGIN = 0x38000000, LENGTH = 64K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 2048K }   /* Sections */ SECTIONS /* snip .. */ .myD3memory (NOLOAD): { . = ALIGN(4); *(.myD3memory) . = ALIGN(4); } >RAM_D3 /* etc .. */ }I can then utilize this in main() as follows:uint16_t buffer16[32768] __attribute__ ((section(".myD3memory")));This works exactly as I intended and Build Analyzer shows the correct allocation. However, I now have a new case where I would like to reference the memory area not just as 16-bit unsigned shorts but also 8-bit un

Suppose there are two views: "Screen1" and "Screen2". Depending on which screen is active, we want to do something (like enable or disable an interrupt). Within the Model, what is the proper way to determine which screen is active? Is there an API that returns a string or number, and can someone point me to a simple example of the syntax? Thanks

The NRST pin of Nucleo-G031K8 is always low. The reset button does not do anything. Should not it reset MCU?

I'm setting it to 12.5 Hz. What is the maximum or lower frequency that I should expect? It is not specified in the datasheet. The temperature could be in the range of 15 to 40 ºC.

I found these prompt in my "main.c" of NonSecure generated by MX for NUCLEO L552ZE-Q: /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */ }should it be this? /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE BEGIN 3 */   /* USER CODE END 3 */ } /* USER CODE END WHILE */ }

It is Value A in model.cppAttempt to initialize Value A from the model.cpp function.However, before Value A initializes, setupsrceen() in B_Screenview is executed first, indicating an incorrect value.I want to know how to initialize Value A in model.cpp before setupscreen() in B_Screenview runs.#TouchGFX​ 

I am using one timer (timer2) as pwm generator and i am using 3 channels on it. I wish to set each channel pulse width independently (they are controlling LEDs) from 1 to 100. But from the generated stcubeIDE function, it looks like that the channels pulse width are written sequentially so every time i wish to change one, i need to write other 2, in order. Is that true?P.S. The MCU i use is STM32L031F6P6.Below is generated timer function:static void MX_TIM2_Init(void) {   /* USER CODE BEGIN TIM2_Init 0 */   /* USER CODE END TIM2_Init 0 */   TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_OC_InitTypeDef sConfigOC = {0};   /* USER CODE BEGIN TIM2_Init 1 */   /* USER CODE END TIM2_Init 1 */ htim2.Instance = TIM2; htim2.Init.Prescaler = 40; htim2.Init.CounterMode = TIM_COUNTERMODE_UP; htim2.Init.Period = 100; htim2.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim2.Init.AutoReloadPreload = TIM_AUTORELOA
