STM32 MCUs Boards and hardware tools

Hi,I have STM32H757i eval board, for which I need to implement ethernet TCP/IP protocol.In order to do this, Ping "IP address", itself isn't happening.I'm attaching the Screenshot for the same.Kindly let me know, if there are any changes to be made in configuration in the .ioc of STM32 Cube IDE.   Thanks in advance  

Hello,I am using Nucleo-F401RE MB1136, want to run the board using the HSE, installed 8Mhz crystal on X3 with 22pf capacitors on C33 & C34 and 0 Ohm resistors on R35 & R37.Using the CubeMx, configured the HSE pin as Crystal/Ceramic Resonator, set the clock in the Crystal Configuration for HSE as 8Mhz, tried both the ways, directly using HSE as System Clock and with using the PLL block.Still not able to run the code as the code gets stuck in SystemClock_Config(void), no pulse is generated on the crystal.Is there any step that i missed or some configuration, please guide me if possible. I am new into the Stm world. Provided the snippet of the CubeMx generated code.Thank You __weak HAL_StatusTypeDef HAL_RCC_OscConfig(RCC_OscInitTypeDef *RCC_OscInitStruct) { uint32_t tickstart; uint32_t pll_config; /* Check Null pointer */ if (RCC_OscInitStruct == NULL) { return HAL_ERROR; } /* Check the parameters */ assert_param(IS_RCC_OSCILLATORTYPE(RCC_OscInitStruct-&gt

Hello, I'm working on project with my own design pcb with STM32WB55. I want to program this processor via ST-Link from nucleo STM32F446. Is there a possible to use this programmer to program another type of STM32 processor?  I'm using STM32CubeProgrammer but when I want to connect to my processor it shows this: As you can see in Log it things that I want to connect F446 boar, but I have connect WB55. Please is it possible to program WB55 with this ST-Link from nucleo F446 or I need to have original ST-Link?ST-Link pins are connected correctly to the processor so I dont find any problem (3V3 source is also activated). If you know how to fix it or need more info I will reply asap. Thank you for help! 

hii everyone i am working on stm32h747i-disco board. my task is to live vedio streaming over HTTP server. I have Bcam-OVS camera module and i also flash webcam code based on USB communication  in board which is given by stm.  if any one have idea how to do this please suggest. 

I am trying to 'kliperize' my FlashForge Creator Pro 2 (FFCP2) 3D printer which uses a STM32F405xx MCU.  I was able to connect to it using the ST-LINK utility and a ST-LINK module (see this link for my post on this subject). With the ST-LINK utility I was able to display and then capture the entire 1MB memory of the MCU for safe-keeping in case I ever wanted to restore the original firmware, but now I can no longer connect to the MCU either with ST-LINK utility or ST32MCubeProgrammer.  I have checked and double checked my USB cable and my ST-LINK connections, power-cycled and reset the FFCP2 printer, but nothing seems to work.Have I managed to 'brick' my FFCP2 printer?TIA, Frank

Hey guys,i am a new member. I am using the Nucleo L432kc board for my masters thesis. I want it to work with the lowest power consumption can me. I am using an external very low power RTC, and i am trying to programm it to wake the board up every 30 seconds. Unfortunately it doesnt work. The RTC is connected with i2c with the board and the nINT Pin of the RTC is connected to PA0 Pin of the board for the interrupt. i dont know what i am doing wrong. So i checked the connections and the i2c is fine. but it doesnt work that it counts to 30 then wakes the board up to say "Ich bin wach!" (im awake). I am a new programmer. I first tried with stop mode and configured the PA0 Pin as a GPIO_EXTI.  Can someone maybe help me? this is my code for now:  /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ************************************************************************

Hello there, As the title says, I'm trying to get an RC522 RFID reader to work with my STM32F746-DISCO board for a school project. I just wanted to know if anyone had any libraries they could share to help with this. My current objective is to toggle on/off an LED on the board, manly as a test to get the RFID scanner to interact with the board. Below is a screenshot of the RFID scanner in question. Thanks in advance.

Hello, I am new to STM32 and need help with UART. In recent days I have been trying to deploy my own neural network model on NUCLEO-H755ZI-Q development board. Through ST Edge AI Developer Cloud, I have generated my own CUEB IDE project. In the IDE project, it uses USART3. After reading the development board manual, I learned that USART3 communication between TM32H7 and STLINK is enabled by default, but I cannot receive the data sent through the serial port on the PC side. Then, I used other serial ports such as USART2, USART1 to test serial output, and connected the PC to the development board through a USB to serial port module, but still could not receive data on the PC side.    /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_USART1_UART_Init(); /* USER CODE BEGIN 2 */ uint8_t data[] = "Hello World!\n"; /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ HAL_UART_Transm

Hello,UM2407 is the user manual of the STM32H723ZG Nucleo-144 development board. Likewise, the schematics of this board are available as https://www.st.com/resource/en/schematic_pack/mb1364-h723zg-e01_schematic.pdf.In both the manual and the schematics, there are multiple references to "PF0/PH0" and "PF1/PH1". See, for example, Section 6.5.1. This confuses me, because I don't see how the MCU pin PF0 relates to PH0 (likewise for PF1 and PH1). As far as I can tell, this peculiar labeling is not explained anywhere.In the MCU's datasheet DS13313, there are separate pins for PH0, PF0, PH1, and PF1.Can anyone tell me what I am missing here? Why is the labeling as it is?Cheers, Sidney

EDIT: My apologies, it turns out that since i had auto reload preload enabled and was not setting the CNT back to 0, the timer would keep counting up until a rollover. I wrote a test program to test a 5 ms  PWM single pulse output with a 3-timer master/slave configuration with an automatic period scaling feature that I wrote.you press the onboard user pushbutton to cycle through a couple of presets.TIM22 is used as a prescalar for TIM3 by setting its slave mode as external clock mode 1. then TIM3's TRGO is mapped to TIM'2 trigger source. TIM2 is configured in slave mode reset mode. As far as I'm aware, when TIM3's CNT reaches the ARR, the program should call HAL_TIM_PeriodElapsedCallback() and reset the CNT register, no? However when i'm on preset where TIM3's ARR is set to 4, the controller will seem to 'skip' the entire UE and not trigger an interrupt nor reset TIM2 like it is supposed to. TIM3 will just keep count up. Why is this happening? Attached is my .ioc file.in

HI , I m using stm32f103c6 32k board for my project competition , currently i m using windows 11 i have updated the bootloader , Maple003 driver visible on ports section in device manager but it throws error 10{could not able to start], i had tried multiple tyms to update and install but remains, could any of you please provide better solution in brief

Hi everyone,First, here is my set up:computer: windows 10uC: STM32F030K6T6flashing/debugging hardware tool: ST LINK v2 ( from nucleo board)I have noticed that it takes almost 30 secs to do same operation using CLI (wether directly launching a batch file or launching it from labview) whereas it takes only few second using STL LINK utility. I would like to reach same speed because I want to automize the programming sequence.Do you have any idea that might help ?Here is the batch content, just in case: @Echooffcd c:\prog_config_serieST-LINK_CLI.exe -P C:\prog_config_serie\NextPM_EFS_FB42_23-02-2024.bin 0x08000000 -V while_programmingST-LINK_CLI.exe -Rst

Hello to everyone,Were to start? Let me first try do describe the setup.1. Using and STM32F446 chip on a custom board. The board has 2-32pins slots: Slot A and B.2.For communication I'm using the SPI protocol.3.For slot A using PE12(CKL); PE13(MISO)PE14(MOSI) and for slot B PB13(SCK), PB14(MISO) and PB15(MOSI)4 Each slot has another 4 ADS connected in Slave Mode.The interesting part.First I tried to communicate with the first ADS from the slot A and after a bunch attempts and fails I start checking the schematics I found this Error in schematicsMISO is connected to MOSI! that means that those 4 ADS from Slot A can not be used for moment. I decided to use the Slot B because that one looks connected properly and here I was going nowhere. I was just not getting any response from the ADS , below is the picture from logic annalizer  a quick explanation: according to the documentation the ADS comunicates i 2 byte format. First tels what to do :Read or Write and the second the Address of

Hello, I'm relatively new to the stm32cubeIDE and currently using it to program a self balancing robot using an stm32F103C8T6 chip.My current issue is that when i run the SSD1306 OLED display through SPI I am able to display graphics and text as required but as soon as i add the I2C protocol on to the chip the SSD1306 chooses not to display anything. I haven't coded the I2C to read from the MPU6050 sensor as of yet as I am trying to get around this problem as it seems more a I2C bus problem than a specific device problem.Stm32CubeIDE chip set up STM32F103C8T6 Circuit Diagram I'm using the SSD1306 library provided by afikson on github (afiskon/stm32-ssd1306: STM32 library for working with OLEDs based on SSD1306, SH1106, SH1107 and SSD1309, supports I2C and SPI)Not yet got a library or code for the MPU6050. I should also mention that the SSD1306 CS pin is connected to ground on the module itself (not to the bluepill as seen in the wiring diagram, put it in there for refere

What is the name of the connector used on stlinkv2 programmers like this one? I can use single wires taped together, but hoping there's a standard cable or connector type that will connect better than single header pins taped together.

hi,i am Using STM32G0B1RCT6USB_CLK = 48MHZUSB_DRD_FS---Host_Only_FS,USB_HOST---Mass Storage Host Class,FATFS---USB DiskUSB Interrupt---EnableIf you set it to the above mode and operate it, the USB is recognized and i configured PB4 as an output, which is connected to a green LED.

I have develop a program on STM32F746G-DISCO revision B02 with QSPI  N25Q128A13EF840ENow the new boards revision C03 use the QSPI W25Q128JVEIQ.I have copied the file W25Q128JVEIQ_STM32F746G-DISCO.stldr from CubeIDE 1.16 to the STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader but the external loader is not flash.I need to change some in my code to use this new QSPI chip ?  

Hi,I have started working with the B-G474E-DPOW1 (STM32G474RE). The intention is to use the G474 in a custom design.I can connect and use the board fine with the on-board debugger, but I want to use the TAG-Connector 10-pin header (CN10, as this is the plan for the target board later), but the connection is not recognised in the STM32CubeProgrammer.

Hello, I am working on a diy simracing project which use the STM32F401CCU6 board. I just bought this board and It worked fine until today for a reason I ignore. The board is stuck on the red led, the blue led doesn't light up anymore. I can still find the board in the device manager ( picture under ) but not it is not detected as it shall be in game controller configuartor ( picture under ). I can still erase the sketch on STM32 Cubeprogrammer and upload it but when I disconnect it it stays with the red led.Have anyone any idea on what to do ?Thanks you for your answers, and sorry for my english which isn't very good !

Hi ST,I am using a stm32h743I EVAL Board and trying to connect the 8ohm speaker on CN19. I am using SAI_AudioPlay example from the STM32Cube_FW_H7_V1.11.0 package. I have followed the readme file and got the headphones working fine; to make the speaker working, I have changed the lines below in the main file.codec_init.InputDevice = WM8994_IN_NONE. codec_init.OutputDevice = AUDIO_OUT_DEVICE_SPEAKER.codec_init.Volume = VOLUME_IN_CONVERT (60).But can't heard any sound out of my speaker and after analyzing the init function inside the wm8994.c file, I have done some modifications and the I can be able to hear the sound through speaker, but the sound is very low.Can anyone suggest me, is there any possibility to increase the volume on the speaker, I have gone through almost all the registers and tried increasing the sound of the speaker but failed. Any help really appreciated. Thanks,Murali Chikkanna    

Hi everyoneI want to measure a small voltage of 10mv-50mv of a sine wave.Can i use Internal adc of nucleo board ? what is the lowest voltage i can measure using internal adc.

I have an STM32F411E-DISCO board and I am facing a problem with the I2C1 Peripheral. 1. I configured the I2C1 (PB6 & PB9) to interface with the CS43L22 Audio DAC on the Discovery Board and it gets stuck at waiting for the SB bit in I2C1->SR1 register to be set.2. Then, I configured PB6 as I2C1_SCL and PB9 as I2C1_SDA to interface with an external EEPROM, the 24C256N to write data to the memory. It also gets stuck at waiting for the SB bit in I2C1->SR1 register to be set. 3. Then, I changed the I2C1_SCL to PB8 and kept I2C1_SDA as PB9, and I can successfully write and read the EEPROM. The problem I am facing is, the I2C_SCL for the CS43L22 is mapped to the PB6 of the STM32F411VET6 MCU and it is not possible to have a workaround this. Can anyone help me?

HI EveryoneI am using Nucleof446RE board for uart communication through usb cable which is also my power supplyIs it possible to use external 5V supply for MCU and use USB cable only for uart communication or any uart to usb converters are needed to communicate to PC.Thank you
