Solved

Hi,I'm using an ST25DV04KC tag with the STM32L476 microcontroller as the host. I can write and read from the tag without issues through I2C. However, I'd like to inquire about the feasibility of gradually adding data to an existing NDEF message stored in the tag's memory.I looked into some older topics, and I saw that this might be implemented in future versions. Has this been implemented in any library?I see that it is possible by completely rewriting the message with the new aggregated data. However, this would wear down the memory unnecessarily. So, I would like to simply add the new data to the end of the previous message. I know that to achieve this, I will need to modify the NDEF header to identify these new data. I'd like to know if I should implement this myself or if ST already provides this feature in any library.

The existing version of the ST25RU3993 Reader Suite (ST25RU3993_GUI_v1_8_6_EVAL) is not supporting the C Library files (from en.STSW-ST25RU-CLIB) that are currently available. Please inform by when the new version is releasing.

I could not find yet a specific information regarding IDAU configuration of H5. Is it same as U5 as described in AN5347 ?Edit: I think it is the one in the reference manual (RM0481), I realized colors (Figure 2) indicate the IDAU mapping.

Hello,I am currently designing a board with STM32H747AI MCU. May I ask how it is possible to run the RTOS on it and then program it via USB-C without using special internal components such as ST-Link MCU in order to save as much space as possible? Does the same process also apply to the STM32MP157C MPU?Thank you very much.Regards

I am using a nucleo-f401re board.

Hi all,Is it possible to setup the radio on the STM32WL5x to sniff raw wireless M-bus packages?I do not want to transmit any data, just receive raw packages from meters that are in range.Thank you in advance.

Hi,I would like to program the NUCLEO-WL55J1 as a w-MBus concentrator. Getting data from nearby w-MBus sensors and pass it on to the cloud, while I still have the option to switch to LoRa for data transmitting.Do any of you have an example project, or any guides how to do this.

Hello,Are there any future plans to add HRTIM Support in ST Motor Contol Workbench? As far as i have seen G474 is inculded, but only with TIM1 and TIM8. Though these two are the advanced motor control timers, i need a faster PWM signal for my application.Cheers, G.

Hi,I am making LwIP + TouchGFX project on STM32H750B-DK following the next tutorial:https://github.com/GrzHeller/STM32H750B-DK_TouchGFX_FreeRTOS_MQTT_Example/blob/main/README.mdWhen setting ethernet settings in .ioc I can enable ethernet global interrupt, but can't set preemption priority. I'm not sure if this is the problem, but every time I run the program it goes to HardFault_Handler. Does anyone know why it behaves this way and how to solve it?

Hi,there are a lot of examples and tutorials available that describe how to use a FIR-filter (via function arm_fir_f32()). Unfortunately all these examples are either simple low-, high-, or bandpass-filters. Now what I'm looking for, is a possibility, to have frequency bands (e.g. 16 or something like that) spread across the whole frequency range and each of these frequency bands comes with an own attenuation level.So how can I do that? How can I calculate FIR filter coefficients for several frequency bands? Or is a FIR-filter the wrong way to implement something like that?Thanks! 

I am working with the STM32F769 microcontroller and I can see that a lot of DMA buffers are placed in DTCM in the source code I'm working with. Looking at the data sheet ( https://www.st.com/resource/en/datasheet/stm32f765bi.pdf ) page 20 I don't see a bus between the DMA controllers and the DTCM. Apparently it works so there must be a way for the DMA data to go to/from the DTCM, but how? Is it, in general, recommended to place DMA buffers in DTCM? I mean, just because it's close to the CPU doesn't mean it's close to the DMA peripheral.

by using the cover glass can the sensor still able detect close ranges (after calibration)

I'd like to try using the STM32L011E4Y6TR in a new design.  However, the HSE input has only one pin (RCC_CK_IN) and I'm not sure how to use it with a standard 4 pin crystal that typically connects to 2 mcu pins.  Can someone point me toward a reference design oscillator circuit for the STM32L0 series?

I have a 2D array input buffer. so, what is the correct way to implement the rfft and cfft functions?float fftIn[16][512] is my input. So, I applied for a loop like below:arm_rfft_fast_init_f32(&fftHandler, 512); for(int d =0; d<16; d++){arm_rfft_fast_f32(&fftHandler, &fftIn[d], &fftOut[d], 0);}Is this the correct way?Since the fftout will be complex no. I have taken cfft along the column(by rearranging the 2d array in certain way) like below:Here input is like fft2In[256][32]for(int e = 0; e<256; e++){arm_cfft_f32(&arm_cfft_sR_f32_len16, &fft2In[e], 0, 0);}Again is the correct way to implement? I am getting some output but I don't have a way to verify the result as of now.Please help me with this?  

I modified the software B-G431B-ESC1 for the custom board, but i am missing the hall interrupts some times. Why does it happen? Does software loading cause this issue, i am sending CAN messages at every 10ms of around 10 messages?

Hello st community, I work on stm32F4, and I use with RTC for date time.When I write in RTC a wrong day (for example 30 Feb 2023 or 31 Apr 2023) I havent a error in the result.It is possible to ask if the data is correct ?if (HAL_RTC_SetDate(&hrtc, &sDate_present_tmp, RTC_FORMAT_BIN) == HAL_OK)

Will the TouchGFX and STM Cube IDE let me work with SSD1306 devices? If so how much memory space will I need per image and overall space to run it? The images will be 128x64 pixels. Which range of ST microcontrollers can be used for this? The labels allowed for this post were not relevant, so ignore the "EEPROM devices"

While CAN communication run.If error occurs...(ex. bus_off, error passive, warning status ./... )How to reset?

now I'm about to try 2 PWM outputs on STM32G4, one is 1/2 time-base delayed from another one.I think that it is difficult with using only 1 timer, and if using 2, is it possible?maybe like following..  using TIM2 & TIM3 for example,  both are PWM generate mode (up/down counter)  master = TIM2, slave = TIM3, TIM3 start at TIM2 counter overflowI'm glad to hear someone can advise me.Regards.

  I bought stm32f407g-disc1. I downloaded stm32cubeide. While I am creating a project, I am constantly downloading firmware files and getting the following error. (code generation could not be done most probably because the necessary firmware package is missing). I looked for the solution of the error on the internet but couldn't find anything. it didn't help those. Also, I had a nucleo card before, I didn't have a problem with it, in the mx and ide parts. I will be glad if you help.

Hello, I am trying to boot from the external flash memory that the nucleo-h755zi-q has(addres->0x09000000), but I am having some issues. The idea I was following is :1. Create a Bootloader project, in this project I configure the QuapSPI in the internal flash memory to memory mapped mode2. create the App project (with a basic toggleLed) changing the .ld flash direction to the 0x09000000. Once the project is created I get back to the Bootloader and in debug configurations I linked the Bootloader with the App, so when the Bootloader is debugged the App will too.3. In the Bootloader file I created a function called 'JumpToAplication' that tries to Jump to the app when the quadspi is done. Here is the code of the function ( I also tried using the commented code) :typedef void (*AppFunction)(void);void JumpToApplication(void) {AppFunction appEntryPoint = (AppFunction)APP_START_ADDRESS;//__disable_irq();//SCB->VTOR = APP_START_ADDRESS;appEntryPoint();}Nothing is working and I don´t kno

Hi, I'm currently working on a project that uses TrustZone with non-secure peripherals, but I'm having problems with non-secure interrupts.When I configure USART3 as a secure peripheral in my project, USART3_IRQHandler and GPDMA1_Channel0_IRQHandler interrupts are working fine (in Secure/stm32h5xx_it.c). However, when I configure USART3 as non-secure, these same interrupts don't fire now (now in NonSecure/stm32h5xx_it.c). I verified that the interrupts and DMA are enabled, and that they are included in the NVIC_NS. The USART3 seems to be initialized the right way because using HAL_UART_Transmit works in secure and non-secure modes. However HAL_UART_Transmit_IT and HAL_UART_Transmit_DMA work with USART3 as secure, but not as non-secure.To deepen my investigation, I wanted to see if the problem was with ALL non-secure interrupts. In a different project, I configured ThreadX as non-secure (using TIM1 as SYS) with the same USART3. The TIM1_IRQHandler is firing, but I get the

hello everyone, i'd like to know if i can use the EVALSTDRIVE101 add-on board driven by an stm32-nucleo to drive BLAC motors. Because the datasheet says that they are suitable for BLDC AND PMSM.Otherwise there is some other board that allows driving  blac motors?

Hello everyone,I'm trying to write a driver for the ILI9341 display (8 bit parallel mode, not SPI) using the ST HAL. I couldn't get the libraries I found online working, I imagine for the same reason I can't get mine to work. Obviously I have double checked my wiring.I took an existing Arduino library, stripped a bunch of code away and verified it worked on an Arduino. Then I changed the Arduino specific calls (pinMode, digitalWrite, digitalRead and delay) and converted them into ST HAL equivalent.The code I attached is supposed to print the display ID (I have removed the auto-generated comments). On Arduino it prints `0x9341` (which is correct), instead the ST version prints `0x1a1a1a1a`.I'm using a Nucleo 64 STM32L053R8T6 board and STM32CubeIDE. I have attached a screenshot of the configurations of the pins, but I also configure them at runtime (see the functions ILI9341_PrepareDataPinsForWriting and ILI9341_PrepareDataPinsForReading)I have also added a screenshot of the IDE and of t

We would like to test if the Teseo-VIC3DA module and its corresponding RF connector have been soldered correctly on the carrier board in production environment. For this it would be easiest to just apply a 1575.42 MHz continuous wave signal (un-modulated L1 carrier) to the RF connector and read out the receive signal strength from the Teseo-VIC3DA module. However, in the "Teseo-VIC3 software instructions" documentation we could not find any command for reading receive signal strength within receiver bandwidth.Is there a method to test the module's RF input without GPS signal simulator?
