Hello, I've been using the RTC lately and it works correctly except for one thing, the alarm. Below you can see the function HAL generatedstatic void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; RTC_AlarmTypeDef sAlarm = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 */ /** Initialize RTC Only */ hrtc.Instance = RTC; 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(); } /* USER CODE BEGIN Check_RTC_BKUP */ /*if (HAL_RTCEx_BKUPRead(&hrtc, RTC_BKP_DR1) != 0xBEBE) { // Write Back Up Register 1 Data HAL_PWR_EnableBkUpAccess(); // Writes a data in a RTC Backup data Register 1 HAL_RTCEx

Hello,I'm studing timer, and I wanna raise an interrupt every second using the Timer1.I write this code in main:rcc->APBENR2 |= RCC_APBENR2_TIM1EN_Msk; //Enable Timer1 clocktimer->CNT = 0;timer->ARR = 1000;// up to 1000timer->PSC |= 16000 - 1;//actual MPU frequency: 16MHztimer->EGR |= TIM_EGR_UG_Msk;timer->DIER |= TIM_DIER_UIE_Msk;//Enable Timer1 interruptNVIC_SetPriority(TIM1_BRK_UP_TRG_COM_IRQn , 0x01);NVIC_EnableIRQ(TIM1_BRK_UP_TRG_COM_IRQn);timer->CR1 |= TIM_CR1_ARPE_Msk | TIM_CR1_CEN_Msk;And this IRQ handler: void TIM1_IRQHandler(void){  printf("INT\r\n");  if (TIM1->SR & TIM_SR_UIF)  {    printf("INT\r\n");    TIM1->SR &= ~TIM_SR_UIF; // Pulisci il flag di overflow  }}The problem is that my code stuck in NVIC_EnableIRQ(TIM1_BRK_UP_TRG_COM_IRQn);I have no information also in debug... Could you help me with this interrupt?Thanks a lot!

STM32CUBEIDE:  version 1.14.1PA0-WKUP ------> UART4_TXPA1 ------> UART4_RXOn a new project when enabling the UART4 with interrupt on receive ,everything is working normal .But once I enable PH1 pin as a GPIO_OUTPUT the UART is not transmitting or receiving any more.Any ideas or help please?Update 1: I attached the two code form comparing.Update 2: if I configure the PH1 pin as input the UART4 will work normal

I am am trying to assess the accuracy of the input capture measurements by capturing a stable periodic pulse, setting the output compare on another channel of the same timer to the measurement, and then measuring the offset on a scope. It appears there is a pretty consistent 25ns lag in the input capture measurement. What primarily drives the lag and should/can this be calibrated out?

Hello,I'm working on a vt100 terminal emulator,  so I created a custom widget which decodes input stream and then display it on a TFT-LCD by LTDC. It works fine alone,  after a custom keyboad added on the top, the simulation will crash when the custom widget try to draw the part under the keyboard, and visual studio throws an exception as shown in the screenshot.what cause this result and how can I avoid it?your help will be appraciated.

Hi,We have an issue with a production build of a VL53L1X based design. The VL53L1X is interfaced to a PIC18F micro, I have inherited the codebase and hardware. The initial production run was for 500 units, of these approx 260 passed our production tests and some have been working well in the field for some time.The remaining 240 all exhibit an almost identical failure mode. Basically the readings will only  1 - Uart Output (Legacy Code - Good Sensor) VTOF=345mm (5989) (0) VTOF=346mm (5978) (0) VTOF=346mm (6020) (0) VTOF=344mm (5949) (0) VTOF=345mm (6153) (0) VTOF=346mm (5979) (0) VTOF=347mm (6098) (0) VTOF=345mm (6147) (0) VTOF=347mm (6176) (0) VTOF=346mm (6166) (0) Min: 344, Max: 347, Avg: 345.70, Std Dev: 0.95   2 - Uart Output (Legacy Code - Bad Sensor) VTOF=652mm (33) (1) VTOF=524mm (48) (0) VTOF=571mm (38) (7) VTOF=496mm (25) (1) VTOF=734mm (23) (1) VTOF=570mm (14) (1) VTOF=604mm (30) (1) VTOF=515mm (19) (1) VTOF=550mm (3) (2) VTOF=587m

Hello,I am new on STM32CubeIDE. I try to use SWV to trace some parameters from Nucleo-H743ZI2. At the beginning, everything is ok. I can see the data in the trace window. But the trace will automatically stop after a certain duration. The board is still running, as I can see the LED still blinking. I am thinking if there is any limitation on the trace duration or data size? Can anyone give me some guide where I should check? Thank you.  

When I use STM32Uxx boards with USB device and STM32CubeU5 drivers/libraries - I cannot make use of ADC1.I want to use ADC1 also (not just USB), to measure VCORE and Temperature.It is a SW issue (and it can be fixed), not a HW issue.Details:I use STM32U5xx (e.g. NUCLEO-U5A5ZJ-Q, with user USB-C as USB VCP UART. The related demo for it is in STM32CubeU5 USBX/Ux_Device_CDC_ACM (starting from it for my project).It is a USB device VCP UART demo.The ADC1 is used as USB VSENSE!So, even you configure ADC1 for your own purposes, e.g. you provide your own MX_ADC1_Init() and void HAL_ADC_MspInit(ADC_HandleTypeDef* hadc) - it is not really acting: your config is overwritten by the USB driver:See in file ".../Drivers/BSP/STM32U5xx_Nucleo/stem32u5xx_nucleo_usbpd_pwr.c" that the same ADC1 is initialized again. It overwrites your settings for ADC1. And the measurement done for USB VSENSE seems to change your ADC1 config (e.g. back to one channel only).In function "int32_t BSP_USBPD_PWR_VBUS

Using st25DV tag on our embedded system. In short, the second I2c read does not display the same data that was written. It differs, as the first byte changes to 0xFF. When I write to the mailbox the first time, and then read the data, it's the same. ( usually just a couple of bytes )But when I read it again, I see that the first byte changed to 0xFF, and all of the bytes that I had written were shifted. Here is what it looks like when writing  "01 02" to the mailbox and reading it First read: 01 02 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Second read: ff 01 02 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff  According to the documentation, I can read it multiple times, don't understand why it fails.    

Hi! I have a nucleo WB55 board that I am using for a project. I know with other nucleo boards, it is possible to power them externally with 5V or 7-12V. However, I am not able to verify whether this is possible on the NUCLEO WB55 board, as I can't find the external power supply guidance/instructions in the User Manual.My aim is to power the board directly with either 12V or 5V but I don't know if this is doable, or the how I could go about it if it is. Please let me know your thoughts. 

Hello,I am looking for Gerber files of the SPC58EC-DISP boardIn the CAD resources folder I could find just the schematic, BOM and Layout in a .pdf file.https://www.st.com/en/evaluation-tools/spc58ec-disp.html#cad-resourcesBest regards

Hello Team, I am looking for Battery Management evaluation boards to verify the algorithms like SOC, SOH and SOE, protection and safety modules.   Can anyone suggest suitable STM evaluation boards with software tools for the software development.   I have look through one of the boards EVAL-L9963E-MCU evaluation board, but it is having preloaded GUI to verify the L9963E chip, but I am looking for the software development board to write the algorithms and develop the application software by own.   BR Venkat

Hello all,I've encountered an issue while porting 2_Images_KMS B-L4S5I-IOT01 project onto STM32F756ZGTxx.My build fails while compiling nvms_low_level.c file:Source of the issue is FLASH driver for STM32F7, which is different from STM32L4. Do you have maybe some quick fix for it or does it require a bit more tweaking?

I am working on a project for my company that would like to use an STM32 processor that can both connect to a camera for capturing video data, and also connect to a 2TB SD card (SDXC) for storing said video data. We're aiming for the videos to be at least 1080p and 15fps. Ideally, we're also looking for being able to connect a microphone to add audio to the video files.The older version of our product used the STM32L452CEU6. It does not have SDMMC support (because it's the 48-pin version) but we were able to connect an adapter to a SPI peripheral and read/write to a 32GB SD card (SDHC). I've been put on hold for now with testing the adapter with the SDXC card, but in the meantime I wanted to ask if it would generally be possible on this STM32L452CEU6, if there are any differences to account for when using SDXC instead of SDHC, etc.We were also looking into changing the processor to STM32U599/5A9 instead (of which all versions do support SDMMC). I think it should still be able to suppor

I'm developing a new project based on STM32G431RB using STM32CubeIDE 14.1.0 on macOSI'm having touble where the program will hang at the first call of HAL_Delay() and digging deeper it's hanging because HAL_GetTick always returns 0It looks like the SysTick timer is not running, or it's interrupt is not being called.I do not have interrupts enabled on any other peripherals.I have TIM1 configured as CH1_CH1N and that is working.I have TIM2 configured in Encoder mode, and that is working too.The only thing that is not working seems to be the System Timer.What could I possibly have done to disable it?My clock source is set to HSIHere is my "main"int main(void){  /* USER CODE BEGIN 1 */ uint8_t msg[64]; uint32_t lastCount;  /* USER CODE END 1 */  /* MCU Configuration--------------------------------------------------------*/  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */  HAL_Init();  /* USER CODE BEGIN Init */  /* USER CO

I am trying to follow the getting started guide (UM2262) for the SBSFU using our own hardware.  I have got as far getting to the main "secure boot and secure firmware update" screen in Tera Term, however when trying to send the .sfb file, I get the following error - "File not correctly received". The only information I can find is in the user manual with the following description for the error- "During a local download procedure, the download operation did not complete successfully (Ymodem protocol issue)." I have checked the Tera Term settings, and they are set as per the getting started guide.I realise that I need the STSAFE - A-110 device connected via I2C, which I have not done yet - could that be the cause?Any ideas would be appreciated, thanks

Hello guys, I hope you're doing well, I'm currently trying to replicate a video I saw on YouTube about audio processing using stm, I'm just starting to develop for stm and I'm having some doubts, mainly in terms of libs. I'm trying to convert between int and float and I'm almost sure there's a lib that does this, in the video it uses INT16_TO_FLOAT and FLOAT_TO_INT16, do you know how I can use them? Below is a section of the video showing how they are used. Thanks in advance for your help. leftIn = INT16_TO_FLOAT * inBufPtr[n];outBufPtr[n] = (int16_t)(FLOAT_TO_INT16 * leftOut);https://youtu.be/zlGSxZGwj-E?si=GQmDbewvicybIJrO&t=1049

Hi everyone,I'm working on a project which we use nucleo401re board and IKS01A2 mems expansion board. I mounted IKS01A2 on 401RE board properly and load the datalogterminal.bin file into the microcontroller. After i start unicleo, it connects to the board but does not allow to hit start button. There is nothing on the unicleo screen but it says connected to the board. At first connection it started once but after that i can not start the communication any more.Thank you.

In Keil, if you open a file with the extension .map, you can find information about starting address of stack and so on. See screen.How can I determine the starting address of the stack in CubeIDE?

Hi,I want to know if there is a provision to lock an entire area in ST25TV tags. I can see from the datasheet that blocks 0 and 1 can be locked, but I cannot see anything for other blocks. I know that I can use a password to do same but I do not want to use passwords. Basically, I want to write to an area in the tag and make it non-editable forever. Is this possible ?

I have a VL53L8CX time of flight sensor connected via I2C on a custom board. The Board has other devices that can talk on I2C no problem. now i cant see the i2c address of the ToF device. from my understanding everything seems to be fine and in accordance with the datasheet. However there are two things that might be not correct and i want to make sure that my assumptions are not wrong. about the LPn pin (A2) in the datasheet this is written:Enables communication. Drive this pin to logic 0to disable I²C communication when the device isin low-power mode. Drive this pin to logic 1 toenable I²C communication in low-power mode.This pin is typically used when you need tochange the I²C address in multidevice systems. Ifit is not used, or if interfacing via the SPI,connect to IOVDD with a 47 kΩ pullup resistor I dont plan to use the low power i2c mode. so i connected it to IOVDD via a 47kohm resistor. Was this correct? the other thing i am not sure about are

Hello community ,I have configured STM32G030 as SPI Slave in DMA mode where master commands poll rate at 50 ms . I have set NSS pin as Hardware input as it is slave . As soon as NSS pin PB0 detects ,SPI DMA transmission starts in hardware level. Payload length is 9 Bytes where last two bytes are dummy . sometimes one bit is in 7th byte's nibble(checksum) is getting left shifted by 1 . so checksum is getting failed . example:- {0x44,0x00,0x00,0x11,0x00,0x00,0x8a,0x00,0x00,};(checksum should be 0x89 (1000 1001) ,but it is received as 0x8a(1000 1010))kindly give your suggestions for solving this    SPI_HandleTypeDef spi_handle; DMA_HandleTypeDef hdma_spi1_tx; DMA_HandleTypeDef hdma_spi1_rx; uint8_t hctrl_input_msg[10]; uint8_t hctrl_output_msg[10] ; void HAL_SPI_MspInit(SPI_HandleTypeDef *hspi) { GPIO_InitTypeDef GPIO_InitStruct; if(hspi->Instance == MB_SPI) { /* USER CODE BEGIN SPI1_MspInit 0 */ /* USER CODE END SPI1_MspInit 0 */

Hi there!Experimenting FLASH reading/writing I done a fanny test that is giving an unexpected (to me) result.Basically:1) I defined  2 32 bytes buffers (aRbuff for read, and aWbuff for write) u32t aWbuff[8U] = { 0x00010203, 0x04050607, 0x08090A0B, 0x0C0D0E0F, 0x10111213, 0x14151617, 0x18191A1B, 0x1C1D1E1F }; volatile u32t aRbuff[8U] = {0};  2) I implemented my read, write and erase function and i integrated them into the main infinite loop  if(bIsErase == TRUE) { EraseFLASHsectors(uiADRtest, uiSect2Erase); bIsErase = FALSE; } if(bIsWrite == TRUE) { printf("Writing FLASH memory...\r\n"); WriteFLASHdata(uiADRtest, aWbuff, 32U); bIsWrite = FALSE; } if(bIsRead == TRUE) { printf("\r\n"); printf("Reading flash...\r\n"); ReadFLASHdata(uiADRtest, aRbuff, 8U); printf("0x%08X, 0x%08X, 0x%08X, 0x%08X,\r\n", aRbuff[0], aRbuff[1], aRbuff[2], aRbuff[3]); printf("0x%08X, 0x%08X, 0x%08X, 0x%08X,\r\n", aRbuff[4], aRbuff[5], aRbuff[6], aRbuff[7
