I'm trying to create a Makefile-based project for the STM32WL55CCUx microcontroller but it's not possible.Why is it disabled? Is there a workaround?Thanks in advance.

Hello,While using the RTC_BKP registers with HAL_RTCEx_BKUPWrite seems all right, the definition of the registers in stm32wb55wxx.h are not. Maybe they should not be present, or they should be fixed, but having symbols defined that do not lead to what their name suggests doesn't look right to me./******************** Bits definition for RTC_BKP0R register ****************/ #define RTC_BKP0R_Pos (0U) #define RTC_BKP0R_Msk (0xFFFFFFFFUL << RTC_BKP0R_Pos) /*!< 0xFFFFFFFF */ #define RTC_BKP0R RTC_BKP0R_Msk /*!< RTC backup register 0 */   /******************** Bits definition for RTC_BKP1R register ****************/ #define RTC_BKP1R_Pos (0U) #define RTC_BKP1R_Msk (0xFFFFFFFFUL << RTC_BKP1R_Pos) /*!< 0xFFFFFFFF */ #define RTC_BKP1R RTC_BKP1R_Msk /*!< RTC backup register 1 */   /******************** Bits definition for RTC_BKP2R register ****************/ #define RTC_BKP2R_Pos (0U) #define RTC_BKP2R_Msk (0xFFFFFFFFUL << RTC_BKP2R_Pos) /*!< 0xFFFFFFF

Hi, I'd like to use a ST25R3911 in order to detect a tag at approximately 20cm.Do you think it's possible ?--> I'll use custom antenna, and probably a custom protocol in order to read a small quantity of data ( my objectif is to read the data in 1ms)

Greetings!I am working STM32F691 . I want to flash images to QSPI flash memory without using tftp . Requesting you to kindly help us with procedure/steps for the same.Thanks in advance

Hi,I try to compile my custom system, which is based on the Cubemx in the latest V4.0.0 ecosystem.

Hi,I'm interested in working with ML and AI on STM32, after spending some time looking through ST documentation I think using NanoEdge AI Studio + ST board is the quickest way to help me understand things.From what I can see, the latest available function pack from ST is FP_AI_MONITOR1 which currently supports the STEVAL-STWINKT1B, sadly this board is out of stock with a very long lead time... are there plans by ST to have other boards supported by this function pack?I do have the STM32L4-IOT node (B-L475E-IOT01A) so can follow along with this guide:https://wiki.st.com/stm32mcu/wiki/AI:How_to_perform_motion_sensing_on_STM32L4_IoTnodeI see various other boards are supported in NanoEdge AI, so this might be another route in, rather than rely on the function pack.Maybe I'm missing something, or is the current way of things?Many thanks.Anthony

In disco boards and evaluation boards there are 1.5k Ohm resistors, would it be a problem if I use 2k Ohms?

Hello, I am using Nucleo-H743ZI ,I am using timer1 to trigger ADC.My APB1 clock frequency is 240MHz and my ARR register is 240 of timer 1. So my sampling rate of ADC should be 1Msamples/sec. To check it I am toggling a pin whenever ADC conversion complete is done. Instead of 1Msamples/sec I am getting around 250Ksamples/sec what might be the issue.For low PWM frequency the relation (TIMER1_freq=APB1_frequency/ARR) is working fine as I decrease ARR my PWM output is not following above formulae.Can anyone help me out what might be the issue?

Hi, ST Community.I have a question about NC pin of M24C16.Is there any problem to connect NC pin to ground?Best regards.

I downloaded the STM32WB MCU Fw pack through  https://github.com/STMicroelectronics/STM32CubeWB.git. Then, I used STM32IDE v 1.10.1 to compile BLE_HeartRateFreeRTOS project. It is complied successfully. Then, I used Device Configuration Tool to update the Pins for USART1 to PA9 and PA10 by accessing BLE_HeartRateFreeRTOS.ioc in the IDE. Besides this change, I had no other changes in Device Configuration Tool. After I saved the change, the code was automatically updated. However, when I complied it again, it shows a lot of errors as the attachment. I do not expect the change of Pins configuration will cause the whole project fail to compile. I also attached the git diff after the Device Configuration Tool change the code for the analysis.Any comments are welcome!Thanks!

I am using NUCLEO-STM32F446re board. It runs at 180MHz SYSCLK and ADC uses APB2CLK that can run at a maximum frequency of 90MHz. I am using STM32CubeIDE and the clock configuration looks as follows:My ADC setup looks as follows:My DMA setup: Just before the while loop I call ADC to start with DMA. /* USER CODE BEGIN PV */ volatile uint16_t adcResultsDMA[2]; const int adcChannelCount=sizeof(adcResultsDMA)/sizeof(adcResultsDMA[0]); /* USER CODE END PV */    ...... ...... ...... ...... int main(void) { /* USER CODE BEGIN 2 */ HAL_ADC_Start_DMA(&hadc1, (uint32_t*)adcResultsDMA, adcChannelCount); /* USER CODE END 2 */   /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { ....... } }And the complete call back function I toggle a PIN and start ADC with DMA again.void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { HAL_GPIO_TogglePin(GPIOA, time_meas_Pin); HAL_ADC_Start_DMA(&hadc1, (uint32_t*)adcResultsDMA, adcChannelCount); }QuestionWhen I us

We are trying to verify the signature generated by the STM signing tool. From this link, in the table for "On STM32MP15x lines", we need to know what data type is used for each field when the signature hash (sha256) is created so we can replicate it.

Hi,Once I flash the base firmware(STM32cube_FW_WL_V1.0.0) in the RAK3172 module, I view the serial print. It displays Europe frequency… then I open the firmware(STM32cube_FW_WL_V1.0.0) and check the file named lora_info.c… in the file Europe and US regions have been enabled.Therefore, I will command Europe and the US region, then I will un-command the Indian region in lorawan_conf.h.Then I run and flash it in the RAK3172 module.Nonetheless, I am faced with this error.ERROR: Region is not defined in the MW: set lorawan_conf.h accordingly.If I need to add any configurations or parameters to lorawan_conf.h?Please guide me on how to resolve this problem. I attached the screenshots belowThank You

Hi,i'm needing to save the date and time on RTC backup register constantly (like once every second) in order to restore the saved time if the MCU was reseted, but im not sure if this registers could be written so constantly.

I was analyzing stm32mp15 disco and eval board schematics for my project. I noticed that DDR pinning are not the same between them. Disco boards have 512MB and EVAL boards have 2x512MB. My project also going to have two variants. I wanted to know why pinouts of these two schematics are different and can I use same pcb for both of my variants with one 1x512 and other with 2x512. (1x512 will have two locations on the pcb but only one chip. Is it possible?)

Hello!I'm working on a STM32H743I use a USB DEVICE driver (pins PB14 and PB15) : only AF12 is possibleI also use a SD card driver (PC8 ... PC12) : only AF12 is possible(Alternate function mapping is described in the datasheet https://www.mouser.fr/datasheet/2/389/stm32h743vi-1760857.pdf page 89)But I did not find this information: is it possible to use the same alternate functions for 2 different peripherals, on 2 different ports?Thanks a lot for your help!Jean

I am trying to transmit repeatedly using HAL_UART_Transmit_DMA(). The first transmit works. All following fail. The HAL_UART_TxCpltCallback() does not fire. All information I can find on this says you have to check the box 'USART1 global interrupt/...After checking that box I get the error:multiple definition of `USART1_IRQHandler'; ./Application/User/stm32f30x_mc_it.o:C:/Software/STM32CubeIDE/STM32-20220817_mcrot/Src/stm32f30x_mc_it.c:147: first defined here.Searching for 'usart1' in stm32f30x_mc_it.c reveals there is no such definition. In fact the only mention of this function is in the startup file and stm32fxx_it.c. There is a definition for USART_IRQHandler in stm32f30x_mc_it.c.I'm using the reference manual UM1786. Is there something better? The section 'How to use this driver' on p. 598 is not much use because after generating the code with CubeMX it is not clear what still needs to be done.So do I need to enable global interrupts and if so, how do I get past this issue?

Hi!I'm starting a hostless BlueNRG-M2 application (this application runs directly on BlueNRG-M2's Cortex-M0, not on an external MCU).I was able to find and run the example projects using the "STSW-BLUENRG1-DK" package, but I did not find a way to configure the pins and build a base project using CubeMX.I was wondering if there is support for this MCU on CubeMX or not. Because right now I'm using the examples to build my own application, and I'm not sure if that's the right approach.Thanks!

If I try to use the import comand, from File menu of STM32CubeIDE, to load an example selecting "import STM32Cube example" option I can't load a project only available in source form. The window that open, were we have a list of available projects for a specific board, in my case NUCLEO_L152RE, only shows the example projects (I think) that have a predefined project structure. Then for me it is non sense to put examples in MCU package extension that I can't use. Or, and this is the wrost, if I want to use it I have to choose a way to convert this example project from a toolchain format; a way abssurdely complicated.I kindly ask help to solve this problem or someone to tell me that isn't possible to do what I want. Thanks in advance.

I have a scroll wheel containing a dynamically-created list of items that I would like to be able to traverse using swiping or dragging motions. When the desired item is in view, I want the user to be able to select it with a touch press, just like you would with a button.According to the API documentation, the public function setItemSelectedCallback is supposed to be called when the selected item is clicked. The setAnimateToCallback is supposed to be called when the scroll wheel animates to a new item. I have set both of these up, but I get both callbacks every time the AnimatedTo item changes. In other words, I can swipe down on my list, and when the animation stops, I always get both callbacks, even though I did not click on any item. This seems like improper behavior.How do I get a 'clicked-on' item? I do realize that the 'clicked-on' item will be animated to become the selected item. I just don't want to get the SelectedItemCallback from a swipe or a drag.FYI, I have modified the

Hi,I am using a STM32H7B3I_DK board with a graphics app using TouchGFX. I'm only using 7% of this and would like to use the top end of this memory to store system tuneable parameters, WiFi SSID's, controller tuning parameters etc.Has anyone done this or something similar?I understand you have to switch memory modes to erase and write.I could work it out, but I'm a bit pressed for time so if someone has done it that would help me greatly. I would have used the battery backed (4k) ram on the MPU, but sadly the designer didn't make this available, you have to cut tracks to separate the Vbat from Vdd.I am developing a project using the Inventek WiFi module which I intend to post when I've finished the documentation (README). I will incorporate the OCTO Spi code into this as a working project for others to use.RegardsRob
