Hello I was wondering are there any materials or examples online that describe how to enable  wifi module provided with the board? Wifi Module that I have is MB1486. Also I could not find the datasheet of the module, only the schematic. Thank you in advance. 

Hi,Where can I find a documentation for the version 4 of X-CUBE-CRYPTOLIB ?Regards,Fred.

I need to debug an application code which is not on the default flash address (0x8000000) but it is at 0x8008000. I just changed the flash origin address to that value. When the execution reaches the CAN initialization part, the program counter goes outside of program code (0x8000f44). Note that the code work as expected if I move the origin flash address to the default value in the linker script.Here is a minimum reproducible example: #include "main.h" CAN_HandleTypeDef hcan1; void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_CAN1_Init(void); int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_CAN1_Init(); /* USER CODE BEGIN 2 */ // Setup can const uint32_t filter_mask = 0x00000000; const uint32_t filter_id = 0x00000000; CAN_FilterTypeDef canfilterconfig = (CAN_FilterTypeDef) { .FilterBank = 0, .FilterActivation = CAN_FILTER_ENABLE, .FilterFIFOAssignment = CAN_FILTER_FIFO0, .FilterMaskIdHigh = (filter_mask >

Hello everyone,I'm having trouble updating the STLINK on my Nucleo F446-RE board. CubeProgrammer allows me to read the microcontroller's memory without any problem, but when I try to update the STLINK firmware, the following happens:It is detected (although it does not provide information about the current firmware or version):However, when I click on "Open in update mode", it becomes "not connected" and I cannot update the firmware. This is a problem because CubeIDE requires me to update the STLINK in order to debug. What could be failing? What am I doing wrong? I had not used the board or CubeIDE for a few months, and upon returning to work, I find that I cannot use it. Could it be something related to USB drivers?Thank you in advance for any help or advice you can provide!

HelloI would like to ask for some advice regarding a liquid crystal module that I would like to use with my ST Nucleo-F410RB prototyping board. The display type is BC1202A. It can display 12 characters in two lines and it has an 8-bit (or 4-bit) bidirectional control bus. I'm a beginner in STM32 microcontrollers and I have never interfaced any LC displays, so I wanted to ask if there's some tutorials or example codes that I could use to get started. Thanks!BC1202A LC display

 

Hello guys!Now a days im facing issue with ethernet configuration in the latest version of CubeMx 6.8.1.When im configuring the ethernet for my F207 nucleo board in its getting stucked into startup file. and through debugging when im pressing F5 button for manay times, then its getting out from startup file and my code starts working and getting pinged from my PC. But when im generating code from CubeMx 5.4.0 version for same configuration, its working fine. im not geeting any issues with this version.has anyone resolved this issue? 

I was doing some tests on a NUCLEO-G071RB and I found out that the ADC has always some sort of offset in its digital output. I measure the tension on the MCU's pin and it's zero volts, but when I read the ADC the output is not zero. It can be 26-27 digits, 50-51 digits or 75-76 digits depending on the board that I'm testing. This happens also with an "empty" project where the ADC read is the only action that I'm doing, and I'm sure that the tension on the physical pin is zero Volts. Why I do get this behaviour? Is it normal?

Hi,When I run the below code, I get the result on serial console as in below image which is not as expected. Could you please let me know what I am missing here ?   int main(void) { /* USER CODE BEGIN 1 */ DWT->CTRL |=(1<<0); /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_USART2_UART_Init(); /* USER CODE BEGIN 2 */ SEGGER_UART_init(250000); SEGGER_SYSVIEW_Conf(); //SEGGER_SYSVIEW_Start(); uint8_t data[]= "message \r\n"; //sprintf(usr_msg,"demo of binary semaphore usage between 2 tasks\r\n"); HAL_UART_Transmit(&huart2, data,sizeof(data),HAL_MAX_DELAY);&nbs

I want to communicate with STM32f427 processor and 3 sensors via SPI. I want to use only SPI1 line. I need 3 chip select pins. There are 2 SPI1_NSS pins on the datasheet of the processor. What can I use as 3 CS pins? Is any GPIO pin suitable?

Hi all, I am successfully transferring from a memory location to the data register of USART2 Tx using DMA operation. And the USART2 has been used by the  printf()  to output to the PC. What I don't understand is, what moderates the rate at which DMA moves data from memory location to the Tx data register? Obviously, data cannot be moved to Tx data register faster than it can transmit, otherwise there would be overwrite errors. Nor should the data be moved at a much slower speed than the Tx can handle, otherwise time would be wasted.So what is the mechanism that moves the data to Tx data register at just the right rate?  I did not set any Tx transmit complete flags or ISRs to indicate to the DMA the completion of the last transmission out of the Tx data register.    Thanks in advance for your help and explanation!

Hi all, recently I made a board with H725RGV6, but when I tried to flash a test firmware for the first time, I got " Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication" from STM32CubeProgrammer (I'm using STLink V2). I measured the power supply and VCAP, VDD looks good at 3.1v, but the VCAP is only 100mv which is not correct. I also tried to remove the third 2.2uF for VCAP and connect PIN66 to PIN49, so VCAP is around 80mv.- I've checked the orientation.- I soldered the chip with a 700F heat gun and tried 3 chips in total.- Updates: I tried to supply 1.2V to VCAP, then I can connect to the chip. But why? Shouldn't the chip have internal LDO?Below is the power supply part schematic. Does any one have any suggestions? 

Hello, Is the STM32L4P5G-DK Discovery Kit also compatible with other STM32L4P5xx components, not just the STM32L4P5AG? Thanks in advance,Sarvesh

Hello, I have a question regarding the evaluation parameters for decision tree results. As you can see in the picture below, the Mean Absolute Error and Root Mean Squared Error are high, but the accuracy is also high. I am confused because I thought that low error and high accuracy are supposed to go hand in hand. Can you please clarify this for me?  Kindly,Fehmi

Hey, i have ported the iperf2 example(https://github.com/STMicroelectronics/STM32CubeH5/tree/main/Projects/NUCLEO-H563ZI/Applications/NetXDuo/Nx_Iperf) of the H563 board to the H573i-DK Board.It pretty much works as expected now, but the TX performance is a little bit poor. I expected >95Mbit/Sec for all tests. I got the following results (I ran each test about 10 times and took the average values). - TCP TX: 85.00 Mbits/sec- TCP RX: 93.41 Mbits/sec- UDP TX: 95.20 Mbits/sec- UDP RX: 99 Mbits/sec Executed Commands on the host system (Ubuntu22.04, iperf version 2.1.5 (3 December 2021) pthreads)- TCP TX: `iperf -s`- TCP RX: `iperf -c 192.168.1.101`- UDP TX: `iperf -s -u`- UDP RX: `iperf -c 192.168.1.101 -u -b 200M`  I'm currently trying to benchmark another setup with modified ethernet settings and got even poorer results for TCP TX.Because of that  I'm wondering whats the bottleneck here. Is it the CPU?I'd appreciate any hints or suggestions on how to fin

I was using the SystemWorkbench for years and everything OK.  Recently changed to STM32CubeIDE and also able to build and debug within hours with released ST project "STM32Cube_FW_F4_V1.28.0".Have tried to use the new "STM32 VS Code Extension" in VSCode as it is getting popular.1. Followed the instructions to install "STM32CubeCLT", note : I installed in different location "C:\Tools\STM\STM32CubeCLT"2. Modified the "WINDOWS_ST_CLT_PATH" and "TOOLCHAIN_DIRECTORIES" in gcc-arm-none-eabi.cmake, and the project is built successful - OK.3. Try to "Debug" the project but it shows error message : Questions :For STM32CubeIDE, it is using OpenOCD.  For VSCode, How to configured and setup to use the Debug Tools under STM32CubeCLT ?Thanks

HI,The driver file I downloaded from the official website is version 1.2.8.(stsw-img029)But when I downloaded the Demo(X-CUBE-TOF1), I found that it uses version 1.2.10.Should I use the latest one? Thanks

I'm using an STM32F446RE MCU on a custom board and I developed a custom bootloader. The bootloader starts at 0x8000000, while the application code starts at 0x8008000. Inside the bootloader I use timer 14 with interrupt and when I need to jump I use the following code: HAL_CAN_DeactivateNotification(&hcan1, CAN_IT_RX_FIFO0_MSG_PENDING); HAL_CAN_Stop(&hcan1); HAL_CAN_DeInit(&hcan1); HAL_TIM_Base_Stop_IT(&htim14); // Note this HAL_TIM_Base_DeInit(&htim14); // Note this HAL_RCC_DeInit(); HAL_DeInit(); SysTick->CTRL = 0; SysTick->LOAD = 0; SysTick->VAL = 0; uint32_t JumpAddress = *(__IO uint32_t*) (APPLICATION_ADDRESS + 4); pFunction Jump_To_Application = (pFunction) JumpAddress; SCB->VTOR = APPLICATION_ADDRESS; __set_MSP(*(__IO uint32_t*) (APPLICATION_ADDRESS )); Jump_To_Application();  Now inside the application code I need the same timer 14 and I also want to debug the application code. The debugger works perfectly until the execution reach

This is a warning listed under the "Problems" tab in STM32CubeIDE (1.1.0). I am seeing some strange behavior and am wondering if this is the cause.The strange behavior I am seeing is that often when I change something in the TouchGFX Designer and click "Generate Code" then do a Run > Debug in STM32CubeIDE, the change does not take effect. What runs on the target is some previous build (without the changes).Sometimes if I disconnect the target and reconnect it, the latest code is correctly running on the target.

Hello.Recently I've been trying to set up a multichannel ADC. The data of both channels are supposed to be transfered to memory through DMA. I've looked through many examples, read many discussions but none of them addressed my issue. In my CubeIDE CubeMX application I just can't see certain parameters for choosing and therefore cannot keep up with the tutorials. The picture below describes what I should be seeing what I see.  Any Help would be appreciated.

Hello,I want to do GPIO initialization for STM32F769I-DISCOhere, i am using those pins in my code: {GPIO_InitStruct.Pin = EV2_Pin|AF1_Pin|WF5_Pin; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(GPIOF, &GPIO_InitStruct); } EV2_Pin for electrovane AF1_Pin for air-fani am connecting the STM32F769i card to relay card and i want to initialize relays to 0 value.I use this after declaration of pins { GPIO_ctrl_relay_AF1(GPIO_OFF); GPIO_ctrl_relay_EV2(GPIO_OFF); GPIO_ctrl_relay_WF5(GPIO_OFF); } Any Help or suggestion Guys ?

Hello ST, I am trying to integrate ThreadX into TFM_Appli-NonSecure project. Mostly I am able to integrate it and execute but to make a thread run, I have to comment _tx_initialize_low_level(); API in _tx_initialize_kernel_enter() function.This all work smoothly until I try thread context switching. My initial understanding assumption says pendsv_hander is not getting called.Could I get some more insight to resolve this issue as there is no direct example available for this.

Hi, I Have a custom board with stm32h743...
