Solved

I'm using STM32H747I-DISCO board to test. I connected OTG adapter and USB disk to CN1 (OTG HS) port.In my STM32CubeIDE I have USB_OTG_FS enabled and configured.The software initialized the driver (successfully), then I try to mount my USB disk and I get FR_DISK_ERR.I checked in the documentation, that the LD7 should indicate the VBUS voltage presence. The LED is off, so I guess I don't have VBUS voltage.Why is that?Is this related to the USB_HOST settings?Especially I'm interested in Drive_BUS_FS pin. I found nothing in documentation on what pin I should connect it to. I just selected a random free pin and configured it as GPIO output. But it does not help. The LD7 is still off, my USB disk is not mounted.What am I doing wrong here?

I'm developing an STM32WB55 microcontroller but I'm straggling with programming.I want to control the microcontroller using its BLE module but there is no good programming example. So, is there any recommendable example to write the memory of the microcontroller using BLE communication?

In the case of normal wake-up, about 6~7 mA current is consumed and 100~250uA is consumed when going into stop mode.Sometimes, it cannot wake up from stop mode when it consumes about 1.6 to 1.7 mAHere is my code:HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, g_sleep_time, RTC_WAKEUPCLOCK_CK_SPRE_16BITS);   HAL_SuspendTick();   HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);   HAL_ResumeTick();   HAL_RTCEx_DeactivateWakeUpTimer(&hrtc);   SystemClock_Config();I attached schematic.plz, help me.

Hey,i use the STM32H757-EVAL Board and was already able to create a new project in TouchGFX (4.20.0), import it to STM32CubeIDE (1.10.1) and modify GUI and Hardware functionality.In order to have more flexibility and to setup a more clean project, i wanted to create the initial project in the CubeIDE, add the TouchGFX Software Pack and only then start using the TouchGFX Designer for GUI creation.My problem is now, that after generating the CubeIDE project and importing the "ApplicationTemplate.touchgfx.part" file in the designer, the code generation always fails.The logfile says, that the post Generate Target is unable to locate the /.cproject file.The file is located in the "Project_name/CM7" folder. Modifying the Build setting of the "Post Generate Target Command" to the specific file location didn't help unfortunately.Maybe someone here has also encountered this little problem before.Thanks!

Is it possible to use X-NUCLEO-NFC06A1 with a microchip processor and how would I go about doing so? I have configured all of the pins on the microchip processor but can't seem to find any documentation on how to communicate with the NFC06A1 besides the examples given by ST. I know I need to use SPI and I have the microcontroller configured for SPI but not sure what to do from there.I am very green in the world of electronics and would appreciate any help that can be offered.Thanks in advance, I know the question is broad.

When we tried the shutdown command ( shutdown -hP now ) from the debug console, all the PMIC regulators are turned off, except for the BUCK3 VDD regulator used for IO.Both our custom board which uses STPMIC1E and the STM32MP157F-eval board which has STPMIC1A have the same behavior.Is there any configuration which is not letting it to be turned off?Any help is much appreciated.

Hello everybody,I am actually a PC software developer, but would like to be able to update the firmware of the hardware we have developed with our own software.For this purpose I have downloaded the "en.stm32cubeprog_v2-5-0.zip" and installed the Windows version on a Windows 10 (64 Bit) PC.I tried the example "1 example with UART bootloader" from the STM-API.This also works very well under Windows 10/64-bit.(A Windows 10 with 32 bit is unfortunately not available to me for testing)But when testing it with Windows 7 (32 / 64 Bit, both the same effect) I get an error when calling the API-function"connectDfuBootloader".Code:   if ((usbConnectFlag = connectDfuBootloader(dfuList[0].usbIndex)) == 0)   ...The value in "usbConnectFlag" is then equal to "-5", which according to the API description "STM32CubeProgrammer_API.chm" means something like:"Operation not supported or unimplemented on this interface".When using the original GUI-programm of STM it works on Wi

Hi, I really have much exprience with many STM32 products (STM32H7, STM32F4, STM32L, STM32G0, STM32G4).Typically for first board check of new PCB I use ST-Link.I have a weird problem, that my ST-LINK refuses to connect to STM32G491 devices (neither on my own PCBs, nor for Nucleo-G491).If I resolder the controller to STM32G473, then connect works fine. Also Nucleo-G474 connect works fine in ST-Link.Is there anything special to do to connect to STM32G491? (Nucleo-G491 ... I have two such boards, both refuse to connect, but LED blinking all fine... same as G474).

Hello,I have borrowed an STM32F429I-DISC1 with 2.4" QVGA TFT LCD.Unfortunately, I fumbled it and cracked the screen.I'd like to fix it for my friend, but don't want to start tinkering if it'll cause a problem.Does anyone have experience in replacing these screens, if it's at all possible?Any suggestions?Thanks in advance

I have a board with an STM32L0 part that uses an 8MHz MEMS oscillator as the external clock source. I recently observed that using the Crystal/Ceramic option appears to make the SYSCLK run at half the expected rate. Using the correct BYPASS option produces the expected SYSCLK frequency. I thought the BYPASS option simply frees up the clock out pin for use as a GPIO. Other boards I've made with F4 and G4 parts seem to maintain the same SYSCLK for both Crystal/Ceramic and BYPASS configurations. Obviously this is not a problem, I was just curious about the observed behavior and couldn't find more detailed information about this in the datasheets.

I am working on an existing project based on the STM32H750 where I want to stop overheating by reducing the CPU frequency.Currently I use 400MHz and I want to lower it to 200MHz. I have peripherals (LCD and SPI flash) as well as timers (TIM1,2,5) that are affected by this change.My question is which adaptions to the Timers and possibly the initialization of LCD, ext. flash I have to make when changing the CPU frequency? Is there a lower limit for the LCD bus frequency for example?For the timers I adapted the prescalers but that doesn't do the job yet. (black LCD screen and crash)My old clock config: My new tentative clock config: 

Hi,I'm using the STM32H743 device.my main loop sends nonstop UDP messages perfectly.I decided that I want to add a debug option that when my code has an issue and it stuck in one of the handlers (such as "HardFault_Handler") endless loops, he will send a nonstop special UDP message that indicates that a problem occurred from within the handler endless loop.I wrote the code, but I see no udp message, when I used the IDE debug option I notice the code is stalling inside the HAL_ETH_Transmit method under the loop "/* Wait for data to be transmitted or timeout occurred */".any idea why in the main loop the udp messages were sent with no problem and under the Handlers it stalls? do I need to initialize something before sending it?pls, help!thank you !!

Hi,I am using nordic MCU to operate LSM303AGR magnetometer device. My goal is to get a Z-axis interrupt upon crossing the pre-calibrated threshold.The i2c write and reads are working fine.INT bit of register 64h (INT_SOURCE_REG_M) is responding when getting a magnet nearby (when polling this register), yet the interrupt pin stays low all the time (verified with a logic analyzer).MCU pin is configured as input without pullup.The following register writes are being performed by the firmware:1. Write 00h in CFG_REG_A_M // Turn on the magnetometer // ODR = 10 Hz 2. Write 40h in CFG_REG_C_M // Interrupt driven on INT_MAG/DRDY pin 3. Write 80h in INT_THS_L_REG_M // Set a threshold equal to 128 (expressed in LSB)   Write 00h in INT_THS_H_REG_M 4. Write E7h in INT_CTRL_REG_M // Enable a latched active-high interrupt on the three axesWe tried to set the INT_CTRL_REG_M to 0x25 and the CFG_REG_C_M to 0x41 and still no change in the pin reading.Can you please hel

How do I get a callback function for the HAL_TIM_OnePulse_Start_IT function?I have a STM32G071 Nucleo board.I whish to start a one-shot timer that calls an interrupt callback function when the time has elapsed. For this I have chosen the timer 6 and had the CubeMX, to generate the code:static void MX_TIM6_Init(void) {   /* USER CODE BEGIN TIM6_Init 0 */   /* USER CODE END TIM6_Init 0 */   TIM_MasterConfigTypeDef sMasterConfig = {0};   /* USER CODE BEGIN TIM6_Init 1 */   /* USER CODE END TIM6_Init 1 */ htim6.Instance = TIM6; htim6.Init.Prescaler = 3; htim6.Init.CounterMode = TIM_COUNTERMODE_UP; htim6.Init.Period = 40000; htim6.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim6) != HAL_OK) { Error_Handler(); } if (HAL_TIM_OnePulse_Init(&htim6, TIM_OPMODE_SINGLE) != HAL_OK) { Error_Handler(); } sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE; sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISA

Hello - I'm wondering if the STSPIN32G4 can be utilized to drive a brushed motor rather than a three-phase brushless motor that it is marketed for. Alternatively, are there any chips within STMicro that are meant for brushed motors that have a combined MCU and gate driver like the STSPIN32G4?Thank you!-Shane

Hi there,I am just starting touchGFX. I created a project in following steps:create IOC file.. enable touchGFX 4.20.0 , choose display as BW, 128*64, interface:custom, and generate code via STM32CubeMX for STM32CubeIDE.open .part file via touchGFX designer... choose blank templete to import.add widget: text area. Save and generate code in touchGFX designer. go back to STM32CubeIDE, open project. and refresh project.build project... Then I got the compilation error in "../TouchGFX/target/generated/TouchGFXConfiguration.cpp:35:8: error: 'LCD1bpp' does not name a type  35 | static LCD1bpp display;". seems some header file is not included... so the class definition is not included... but I understand from the doc, all these generated files are not supposed to be modified... So I am asking for help: anything I did wrong here? Thanks and Best Regards****

Is there a walk-through or example of how to setup secure boot using a custom device tree?As a side note, the following page returns "Permission Error", is that expected behaviour?https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot
