Hai ,am trying to make a pwm signal to drive an H bridge driver  ,My board is Nucleo-F070RBI am using the following function HAL_TIM_PWM_Start_IT(&htim1, TIM_CHANNEL_1);HAL_TIMEx_PWMN_Start_IT(&htim1, TIM_CHANNEL_1);HAL_TIM_PWM_Start_IT(&htim1, TIM_CHANNEL_2);HAL_TIMEx_PWMN_Start_IT(&htim1, TIM_CHANNEL_2); But not getting any wave  

I'm porting a QSPI bootloader over from a design that 1 flash chip to 2 flash chips in parallel (10 bit mode, common CS).  I am not sure how the addressing works now that there are 2 chips in parallel.  I feel like the only thing STM32 says on the matter is in AN4760 in that even bytes goto one flash 1 and odd bytes goto the flash 2.If I have something that is addressed at 0x1000 internally by the STM32, when sending QSPI commands to write or erase to the QSPI do I need to double the address (to 0x2000) first?  Or does the QSPI interface in the STM32 already do that for me? 

Hi,I recently bought a ST-LINK/V2 dongle and it didn't work. I checked the insides of it to see that the microcontroller inside wasn't an ST one, but a Geehy clone microcontroller. I bought another, which was not a dongle, it was the larger white version. I made sure it was authentic. This gave me the same problems as the first one. I am trying to program an STM32F030F4P6 microcontroller for my custom board using SWD with 4 pins: CLK, DIO, 3V3 and GND. They are connected using screw terminals, which I have connected to the ST-LINK/V2 via jumper wires to pins 9, 7, 19, 20. Same order as above. I have not been able to program it once. I have verified with a multimeter that the jumper wires are connected to the corresponding pins on the MCU. I have made sure that VDD and VDDA are connected. Boot0 is low, NRST is high. I have attempted to program it using different IDE's, which include STM32CubeIDE and Keil microVision 5.When I connect the ST-LINK to my Windows 11 PC and open STM32 ST-LINK

i am using stm32mp135-dk board i am install the  STM32MP1-Ecosystem-v5.0.0 Starter Package    now i want to connect the board with my laptop using putty software ,i have the ip address of the board but did't have the password of the board. what will be the default password??  

Hi all,I am using the NUCLEO-F446RE with the STM32F446RE. I am trying to interface with an external dual sampling differential ADC: ADS9224R.ADC Timing DiagramThe ADC can provide samples at up to 3M/s. I would be happy to achieve ~0.8M/s sampling.I have been struggling to meet the timing that I require and can only reach ~180kHz with the STM32. My problem is that initiating separate SPI receive calls takes too long between commands.Running the following code to initiate back to back SPI reads:HAL_GPIO_WritePin(GPIOB, GPIO_PIN_6, GPIO_PIN_RESET); //CS LOW HAL_SPI_Receive(&hspi1, (uint8_t *)spi_buffer, 1,40); HAL_GPIO_WritePin(GPIOB, GPIO_PIN_6, GPIO_PIN_SET); //CS high   HAL_GPIO_WritePin(GPIOB, GPIO_PIN_6, GPIO_PIN_RESET); //CS LOW HAL_SPI_Receive(&hspi1, (uint8_t *)spi_buffer, 1,40); HAL_GPIO_WritePin(GPIOB, GPIO_PIN_6, GPIO_PIN_SET); //CS highProduces the following timing: The STM32 is operating at 180MHz, and the SPI CLK is at ~30MHz. You can see that once the

I need to communicate by I2C my board that contains the LIS3DH accelerometer with the MKI109V3 adapter board. In order to evaluate if the sensor readings are correct.From what I understand, the MKI109V3 evaluation board allows communication via SPI and I2C. But, still not able to do it by I2C.In my project I use the following signals:SCLSDAWhile the signals:SDO/SA0 (connected to 3V3)CS (connected to 3V3)And I am using Unico-GUI software version 9.12.0.0And I have the following response.I would like to know what I have to do to establish I2C communication between my board (slave) and the MKI109V3 board (master).

Hello,I'm working on a project that requires collecting data from the LSM6DSOTR sensor. I want to use the ML capabilities of the IMU, but it seems like I need an ST evaluation board to use the software? I currently have the the LSM6DSO connected to an STM32 board, already programmed with data acquisition. It seemed that I could use NRF Connect to acquire the data, and Weka to obtain the .ufc, but I don't know if this is accurate. TLDR: Do I need an ST evaluation board to use the ML capabilities of the LSM6DSOTR?

Is USART1 on APB1 (AN5593, tab.17) or APB2 (DS, RM, CubeMX) and USART2 on APB1 (DS, RM, CubeMX) or APB2 (AN5593, tab.17)? Guess, there is an issue in an5593-how-to-use-the-gpdma-for-stm32u5-series-microcontrollers-stmicroelectronics Rv.4 , isn‘t it?

Can someone please tell me how to start multiple channels of  ADC? from zero using DMA? I am able to do it using the Polling method but I'm finding it difficult using the DMA

Hi! I am using an STM32F103C8T6 mikrocontroller and i program with makefile and VsCode. I use the CAN on it and i need to work with STDID and a EXTID. On the bus there is dozens of standart CAN messages and sometime exteneded messages. From the standart ID-s i just need which identifier is 0x7C1 and next to that i need the all exteneded messages too. I would like to direct the standart messages in FiFo1 and the extened to FiFo0 (or inversely doesnt matter just one FiFO for the extened and other for the standart). I have created two canfilterconfig like this: For the exntened:   canfilterconfig_EXT.FilterActivation = CAN_FILTER_ENABLE;   canfilterconfig_EXT.FilterBank = 0;     canfilterconfig_EXT.FilterFIFOAssignment = CAN_RX_FIFO0;   canfilterconfig_EXT.FilterIdHigh = 0x00;    canfilterconfig_EXT.FilterIdLow = 0x04; // IDE bit   canfilterconfig_EXT.FilterMaskIdHigh = 0x00;    canfilterconfig_EXT.FilterMaskIdLow = 0x04; // IDE bit

Hello everyone, for my project I need to enter the secure mode on a em4233 Glastag. I also use X-Cube-NFC6. The rfal-librarys only support tags from STM. I do not know how to send the command to the Tag can some explain or provide a example. Thanks 

https://community.st.com/s/question/0D53W00000PoivmSAB/changing-the-emmc-pins-with-otpI have the same pin mapping as above: SDMMC2_CK - PE3 (AF09)SDMMC2_D0 - PE6 (AF07)SDMMC2_CMD - PG6 (AF10)I programmed the OTP fuses as follows:WORD 3: 0x23000004 (I also program SD as primary and eMMC as secondary)WORD 5: 0x56755395WORD 6: 0x000076A4The problem is that even after flashing the eMMC with the TFA image as per the following procedure: https://u-boot.readthedocs.io/en/latest/board/st/stm32mp1.html#prepare-emmc I still get nothing on the UART4 console.We also put a scope on the SDMMC2_CK line and no clock is detected. Does it mean the BootROM is not accessing the eMMC?Am I missing something?

I am trying to migrate from ecosystem 4.1.0 to 5.0.0 however after getting all the device trees to compile and build plus a new image I am encountering a Panic in optee. The problem is that it just says Panic and I can't tell based on the debug prints which direction to take.The board is a custom design based on the stm32mp157a-dk1 and all the vital components are the same (PMIC, SDMMC, etc)Any suggestions on how I could debug this further?I have attached the full debug console logs and is what I get from the console without the optee debug prints since it's too many lines: �NOTICE: CPU: STM32MP153AAC Rev.Z NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-6.1-yocto-mickledore-mp1-v23.06.21 NOTICE: Board: MBfdd8 Var2.15 Rev.B-14 INFO: Reset reason (0x15): INFO: Power-on Reset (rst_por) INFO: FCONF: Reading TB_FW firmware configuration file from: 0x2ffe2000 INFO: FCONF: Reading firmware configuration information for: stm32mp_io INFO: Using SDMMC INFO: Instanc

For an STM32H747i-DISCO board (800x480 lcd), I have used TouchGFX Designer v4.22.1 to create a very simple project with a box and static graph. The white box was maximized to the full screen. The static graph was untouched.I imported this project into CubeIDE v1.13.2.I want to be able to draw 799 horizontal line segments on the lcd. I am getting close but cannot get the resulting line to reach across the entire screen. It gets about 15% across and then stops.The starting point of this short line can be moved to the right by adding a constant to 'segmentCounter' in  graph1.addDataPoint( segmentCounter , 240 );, but the length of the line doesn't change.Any hints to what I am doing wrong would be appreciated. The attached code should draw 799 one-pixel line line segments. Attached are Screen1View.cpp and .hpp, plus a picture of the display. 

Hello forum and devs!Have one simple question: datasheet of STM32F407ZGT (STM32F40x series) and Cube MX says me, that this MCU doesn't contain USART6_CTS pin, but contain two USART6_CK pins. Is it mistake, and where is USART6_CTS pin?Official datasheet's page:https://www.st.com/resource/en/datasheet/stm32f405rg.pdf 

Hi! I wonder if the P-divider for the PLL1 on the STM32H743 is allowed to be 1.The reference manual (rev. 8 ) states in figure 47 (section 8.5.5) that only values from 2, 4, ... to 128 are allowed. In the register description (section 8.7.13) however, a divider of 1 corresponding to a register value of 0 is also listed as valid. Which one is correct? Kind regards 

Good morning, I have some problems with interrupt priority on the STM32F429.I set up a serial communication on UART1 with this priority// USARTNVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;NVIC_Init ( &NVIC_InitStructure );I also set a TIM1 timer with this priority.// TIM1NVIC_InitStructure.NVIC_IRQChannel = TIM1_UP_TIM10_IRQn;NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;NVIC_Init (&NVIC_InitStructure);Although the serial priority is greater than the timer priority, if I am executing the timer interrupt routine (lasting about 200usec), I have verified that when I receive data via serial at 57600,N,8,1 (and therefore a byte every 156us ) the data is lost because it does not enter the serial interrupt routine.Why does

It would be very useful and I think relative easy to implement: To have an alternative pinout view but instead of the the IC, a view of the nucleo board with the morpho and arduino connectors.Something like this but interactive: https://os.mbed.com/platforms/ST-Nucleo-G474RE/#morpho-headersThanks for taking it into consideration.  

Hi all,I tried to configure timer 14 to generate interrupt every 500 ms . i am toggling an GPIO to measure delay .when put a breakpoint interrupt gets triggered but unable to see waveform in logic analyser of GPIO toggling with delay .My clock frequency is 4 MHZ , desired interval period is 500 ms  so PSC is 2000 , ARR is 1000.Kindly give suggestions   void main() { timer_init(); HAL_TIM_Base_Start_IT(&htim1); while(1) { } } void timer_init() { htim1.Instance = TIM14; htim1.Init.Prescaler = 2000 - 1; htim1.Init.CounterMode = TIM_COUNTERMODE_UP; htim1.Init.Period = 1000 - 1; htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_ENABLE; if (HAL_TIM_Base_Init(&htim1) != HAL_OK) { Error_Handler(); } } void HAL_TIM_Base_MspInit(TIM_HandleTypeDef *htim) { if(htim->Instance == TIM14) { /* Peripheral clock enable */ __HAL_RCC_TIM14_CLK_ENABLE(); /* TIM14 interrupt Init */ HAL_NV

Hi all,Looking to implement FOTA on a custom board which uses the STM32WB55M module. I understand the principles of the FOTA solution and the services/characteristics and have looked over the relevant app note, but I have a couple of questions about how precisely to actually implement the solution.1. Would installing both the OTA application and the user application be a matter of compiling each (OTA app with a linker script specifying a start address of 0x08000000 and the user app at (IIRC) 0x08007000) separately and then loading each binary separately at the respective addresses?2. For custom boards, is it typical to just use the OTA application given in the STM32CubeWB software package (with some slight modifications to, for example, the BSP functions which control Nucleo LEDs)?In other words, what I *think* is the procedure, given that I currently have a custom board with a user application:Modify user app linker script to start at an address beyond where the OTA app will endTake t

Hello,I am not really new, but i have a courious problem.I have a STM32F103CBU6 device (new), and started a new C++ Project with STM32CubeIDE 1.13.2 and the STM32Cube FW_F1 V1.8.5 firmware package.I have a external crystal for both (HSE + LSE) and is configured in RCC.So, if i configure under "SYS" the "Debug: Serial Wire" and Timebase Source: "TIM2" or so, then after compile, and uploading the code and starting with debugger, begins the problem.Code runs with first Breakpoint: HAL_Init();When i try to resume the code, makes my STM32CubeIDE very strange things, my window changes out of the main.c code to "Break at address "0x1ffff766" with no debug information available, or outside of program code.":Question 1: so, why my debugger jumps out of the code to a source that not available ?Is there a Problem since the firmware? or a problem with the STM32CubeIDE?Question 2: Why my code stops at the HAL_Init ?When i try to resume the code after "Break at address "0x1ffff766" with no debug inf

Hello,I encountered a strange problem while using STM32H563.I tried using TPIU to output trace information.When I access the TPIU register(address:0xE0040000) in debugging mode, it will cause debugging to disconnect.Connection cannot be restored through NRST reset,but power on reset can connect to the debugger and the application runs normally.Could you assist me in using TPIU normally on STM32H563?Best Regards.
