Background:1. STM32CubeMX 6.10.02. Test DMA in UART.3. Using STM32CUBEMX to generate codes.Questions:1. I found the project did not includes source codes.2. The HAL_Init(); is in the main function but it did not have source codes to support.3. I also click copy all used libraries into the project folder but it still can't work. Attached is for your reference, might need your help to solve this issue. Thank you.

Hello,I am running the code as shown in the attached file and I get two different behaviours on to identical stm32h735g-dk boards. One of the boards will send exactly 37 can messages when the button for master is clicked and the other board will send a infinite amount of messages. What could be the issue? Any help is welcome!Kind regards,Björn Lindholm

Hello all, I am currently developing on the STM32H563ZI and encountered an issue where, when swapping to Bank 2 to erase/write flash, it simultaneously erases the same address in Bank 1. Here are the steps I followed: Swapped to Bank 2. Used STM Programmer 2.16.0 to flash a bin file to the address 0x8100000. Used STM Programmer 2.16.0 again to flash the same bin file to the address 0x8000000. At this point, the code initially flashed to 0x8100000 was erased. Subsequent tests with writing only a few bytes also resulted in the same situation. Are there any settings I can adjust to avoid this situation? Thank you very much!

Our project uses an external ADC reference voltage of 3.03V.This value is properly set up inside the json I use to generate the inital project code ("amplifyingNetworkVm": 3.03, "polarizationOffset": 1.515).Now I found in the generated code that inside paramters_converison.h, the ADC_REFERENCE_VOLTAGE is set to 3.3V.Where am I supposed to set up the correct value so that it gets used by the code generator and stays when regenerating the project in CubeMX? Can I just manually set it?

I am trying to communicate with an ST25R95 from an ESP32S3 but the the spec isn't very clear on the SPI initialization sequence.and I can't find any complete examples.  I'd like to verify that I can communicate with the ST25R95 by reading the IDN so I've implemented the following sequence and verified that this occurs with a Logic AnalyzerAfter initializing the ESP32 SPI peripheral I setCSn HIGHIRQ_IN HIGHSCLK LOWMOSI LOW(delay)CSn LOWSend one byte over SPI 0x01 //resetCSn HIGH(delay)IRQ_IN HIGH100mSIRQ_IN LOW 100mS   //wake up ST25R95IRQ_IN HIGH100mS(delay)CSn LOWSend 14 bytes over SPI 0x02,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00 //READ IDNCSn HIGH I am expecting the IDN to be returned but instead I get 0xC,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0.

Hello all,I'm working with STM32MP135F-DK board and GC2145 camera that comes with it. My main purpose is to get the image and save it. I tried to use the following documents for this:https://wiki.st.com/stm32mpu/wiki/STM32MP13_V4L2_camera_overview#Grab_a_raw_framehttps://www.st.com/resource/en/application_note/an5478-stm32mp13x-lines-interfacing-with-a-mipi-csi2-camera-stmicroelectronics.pdfI didn't know how to do the "3.1-kernel configuration" step in the first link. So I followed the links below:https://wiki.st.com/stm32mpu/wiki/Menuconfig_or_how_to_configure_kernelAfter this link, I went to the following link:https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_PackageAfter installing some packages here, I went back to the "menuconfig-how to configure kernel" link, and here I got stuck on the following step:I have the specified files but I don't know in which directory I should run the make config or make menuconfig commands.To be honest, I am new to embedded Linux and my ma

Hi, I have an STM32F429I-DISCO1 board. I have been learning how to use it and I thought it would be good to see how the professionals do it by looking at the original firmware. I downloaded en.stsw-stm32138, which has STM32F429I-Discovery_FW-V1.0.3 in it. It seems to have examples for EWARM, MDK-ARM and TrueSTUDIO, but not STM32CubeIDE. This seems a bit odd not supporting your own IDE or have I missed something?Thanks in advance, Lance.

I'm using Nucleo-U545 for my project and set the external interrupt for user button as follow.void HAL_GPIO_EXTI_Rising_Callback(uint16_t GPIO_Pin){if(GPIO_Pin == USER_BUTTON_Pin) {  HAL_GPIO_TogglePin(LED_GREEN_GPIO_Port, LED_GREEN_Pin);  printf("*button pressed\n");}} void HAL_GPIO_EXTI_Falling_Callback(uint16_t GPIO_Pin){  if(GPIO_Pin == USER_BUTTON_Pin) {  HAL_GPIO_TogglePin(LED_GREEN_GPIO_Port, LED_GREEN_Pin);  printf("*button released\n");  }} When I press the button, the rising interrupt reacts relatively fast. But when I release the button, the falling interrupt responds very slowly. It takes almost a second.No matter how hard I look at it, I can't tell why this phenomenon occurs. When I look at the falling wave using an oscilloscope, it falls quickly without being as slow as the falling interrupt reaction rate.

Hi Team, where we are trying interface ENC28J60 in STM32F407VG Microcontroller to use Ethernet, Is there any procedure to create a project in cube ide are any link related to this board how to interface ENC28J60 to STM controller. Best Regards,Gagan Gowda 

I am getting error while connecting ST-link with cube-programmer in STM32H7s78-DK.ERROR:error: cannot connect to access port 0 if you are trying to connect to a device with trustzone enabled please try to connect with hotplug mode

Hi team,I am currently developing a board with the STM32L476RET6. This project involves UART communication (UART4, PA0 and PA1), and I am concerned about EMI due to the fast rising and falling edges of the TX signal. To address this issue, I am implementing a series termination. I already have a 50-ohm controlled impedance board. To complete the design, I need to know the output characteristic impedance of the GPIOs I am using. I have tried to find this information in the datasheet and reference manual, but unfortunately, I could not locate it. Can you help me with this?

Hi!I'm using Nucleo-f429zi board and my trying to configure it to read and write data over modbus RTU (RS485)and i'm using keil uvision 5 to program. I have referred some videos and post on how to configure STM32 and its USART port for modbus communication but when I try to configure RCC in STM32cubeMX i get a error highlightingmaster clock 1 and when i hover mouse courser over it, it says conflict with usb.can someone explain me how to solve this error and why i'm facing this issue? 

I’m using CubeIDE and I want to internally connect peripherals to the comparators. This doesn’t appear to be supported by CubeIDE, but I’m wondering if its still supported by hardware somehow.I’m using an STM32G4 and I see that COMP6 INP lands on PB11, which is the same pin as OPAMP6 OUT. Can a pin overlap like this enable internal routing of OPAMP6 to COMP6?I can also see that OPAMP outputs can be mapped to ADC inputs that also fall on external pins that overlap with COMP comparator inputs. PA2 doubles as COMP2 OUT and ADC1 IN3, which can map internally to OPAMP2_VOUT. Would this work?Similarly, I want to drive a USART RX with comparators routed internally. I see that COMP6 OUT can land on the same pin as USART1 RX. Can I make the COMP drive the USART like this?

I am examining the antenna attached to X-NUCLEO-NFC08A1 and its schematics, and I noticed that there is a 3rd pad at the edge of the antenna board with a connection to GND. I also see the same GND connection through a 0Ω resistor in the provided schematic in DB4702. I've never seen this before in other NFC antenna designs. It seems to short the entire antenna to ground according to the multimeter. What is the purpose of this connection, and will my antenna still work without it? Thank you in advance. 

Hi,I have used different micro-controller boards for many years, Arduino, STM32 and ESP32. I have always used Arduino IDE for all my developments. Recently I have downloaded STM32Cube IDE to see how it works compared to Arduino IDE. I started porting different programs and they went pretty well.In the past I have developed a program to test the speed of different micro-controller boards. The program starts with a larger prime number and checks if its a prime or not. then it does it over and over to see how many times it can checks in 60 seconds. Though it does only arithmetician integer operation, it gives me an idea how fast a board is.So I ported the code from Arduino IDE to STM32Cube IDE, and compared the results for a blue pill STM32 board (STM32F103C8T6 ). I got very different results. Code compiled in Arduino IDE goes through many more loops than the Cube IDE. If I start with a prime number 1990661, with Arduino IDE code can check 589632 times if its a prime or not. For the same

Hi,we have designed a custom board that includes a STHS34PF80 but after triggering a one-shot acquisition, the DRDY bit is never set and reading from the TOBJECT_x and TAMBIENT_x registers without waiting for DRDY only returns 0. We are interfacing the sensor using I2C from an nRF52 SoC.Implemented procedure:Powering up the sensor (+ wait for 500 ms)Enabling block data update (Reg: 0x20, Data: 0x10)Triggering Acquisition (Reg: 0x21, Data: 0x01)Waiting for DRDY bit to be set (Reg: 0x23), Alternatively: Wait 25 ms and reading registers 0x26-0x29 directlyThe sensor ACKs the data transfers so I assume that in terms of the hardware everything is fine, WHO_AM_I (0x0F) correctly returns 0xD3.Am I missing something?Thank you very much in advance!   

Hi all, I need to generate a DAC output which is operating on 2 quadrants and the quadrants may be asymmetrical with respect to both the duty cycle and the amplitude. Attached a picture which better explains what I need. MCU STM32F446RE DAC OUT1 on pin PA4 - triggered by TIM6 DMA channel 1 stream 5 PWM out: TIM1 CH3 with output on pin PA10 frequency range: 10-500Hz (frequency of the DAC waveform) The PWM output is controlling the polarity while the DAC is controlling the output amplitude. The polarity must be changed when the DAC output completes 1 cycle. I need ideas on how to implement it. Since the DAC output is asymmetric I don't know how to create the LUT: should I create a complete LUT with both the quadrants or should I change the LUT array at the polarity change ? In the first case I don't know how to trigger the PWM output in sync with the DAC waveform while, in the second case, I don't know if I have enough time to recalculate the LUT at the polarity change.   Another op

Hello,I have a problem on a STM32H753 which I do not understand.I want to sample some data from ADC with a given time period.So I use the TIM2_TRGO as Event generator for the ADC3 (via EXTSEL)ADC3 is configured in 12 Bit single conversion, in the sequence register there is only one entry, the length ist 1.TIM2 is configured in a way that it generates an Event each 4msFor Data transfer I use the DMA1_Stream0The corresponding DMAMUX channel is set to 115 accordingly.On the ADC input Pin I provide a sinus signal.For debugging reasons I initialise my RAM array with 1.When the transfer is complete, I see in the Data Array that there are missing some data.One result for example: 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2252, 2283, 2258, 2178, 2049, 1880, 1680, 1463, 1245, 1048, 924, 825, 768, 730, 734, 775, 830, 935, 1052, 1250, 1468, 1685, 1883, 2054, 2182, 226

Hi，I am using the PWM1 mode of the STM32G031 TIM1 and I noticed that the rising and falling edge time of its PWM output is about 20 ns. I have used the PWM fast mode but this time is not getting shorter. I would like to know if this time is normal? Because if I use the GPIO output mode to flip the output directly, this time can be as fast as 10nsThanks. 

Hi everyone, I've created a library and placed it in the directory /source/driver/. The library consists of the following files: source/driver/VN9d30Q100.h source/driver/VN9d30Q100.c The problem I'm encountering is that when I try to use a function from this library in my main.cpp file, I get an "undefined reference" error for the function VN9D30Q100_Init(). I've ensured that the header and source files are correctly written, and I believe the issue lies in how I'm compiling and linking these files in SPC5 Studio. Can anyone guide me on how to properly include these files in my project settings, or if there's something else I'm missing? Any help would be greatly appreciated! Thanks in advance,Lucifer

Dears,I didn't find firmware updater components on SPCx58N.Would you please suggest how to solve it  when develop bootloader app on SPC58N.Thanks a lot.

Hello, I am using STM32H7 dual core series. Currently I am planning to enable FreeRTOS in M4 core and let M7 core run in regular fashion. As FreeRTOS uses SysTick, I have given M4 core on of the controller timer. Is there any need to also give M7 core a different timer? As M7 core is not running FreeRTOS, can it continue running on SysTick timer. -Regards

Hi experts,I'm adding to my existing code (that runs on a STM32F105) a function to store a word in the flash.I basically copied the code from the official example based on the HAL libraries, here my function:uint32_t FLASH_Write_Data(uint32_t StartPageAddress, uint32_t *Data, uint16_t NWords) { static FLASH_EraseInitTypeDef EraseInitStruct; uint32_t PageError; /* Unlock the Flash memory to enable the flash control register access */ HAL_FLASH_Unlock(); /* Erase the FLASH area*/ EraseInitStruct.TypeErase = FLASH_TYPEERASE_PAGES; EraseInitStruct.PageAddress = FLASH_USER_START_ADDR; EraseInitStruct.NbPages = (FLASH_USER_END_ADDR - FLASH_USER_START_ADDR) / FLASH_PAGE_SIZE; if (HAL_FLASHEx_Erase(&EraseInitStruct, &PageError) != HAL_OK) { /*Error occurred while page erase.*/ return HAL_FLASH_GetError(); } /* Program the user FLASH area word by word*/ uint32_t i = 0; while (i < NWords) { if (HAL_FLASH_Program(FLASH_TYPEPROGRAM_WORD, StartPageAddress, Data[i])

HI,I would like to use the speaker output on the STM32H563ZIT6. I reviewed the wiki, but there aren't any references about how to play audio with the speaker output. Is it possible to enable this output to play audio?Does the STM32H563ZIT6 have built-in capability to directly convert this digital data to an analog signal for speakers without using an external CS43L22 DAC (Digital-to-Analog Converter)?Regards,Berlin

Hi,thereI'm a new learner and I'm trying to deploy an AI example given by ST official ,I trained the model using example dataset and generated an MDK file.I see there has some APIs for users to create and init neural net work like these:AI_API_ENTRYai_error ai_network_create_and_init(ai_handle* network, const ai_handle activations[ ], const ai_handle weights[ ]);And my questions :Where can I find "network" handle ,"activations" and "weights"?Or does any one can offer me your project as an example?Much thanks.
