Solved

Hello,I'm using the nucleo-h743zi2 board.I am trying to use the USB OTG FS function.The .IOC file settings are as follows:USB_OTG_FS enabledMODE: DEVICE_ONLYVBUS: disableuncheck SOFI provided power through an external source and also swapped the D+ and D- lines of the USB.The USB connection LED on the board turns on, but a USB device recognition error occurs in the Device Manager of my computer.Is there a way to resolve this situation?

What should I do if nobody is answering my question?

AN2606 does a very good job of describing communication peripheral usage by the bootloader, but not so much GPIO pins.Can I get a description of how each of the GPIO pins on the ST32U545REI6Q is configured by the bootloader? This could be important in determining behavior when new chips arrive from the factory and are placed on our custom circuit boards.Thank you! 

Hi Folks, I am using a STM32F070F6P6 microcontroller for a very basic/simple project to help learn the STM32 platform, etc.I am getting an error when I attempt to build my project that my code overflows FLASH memory by quite a bit.  I did a test on a new project, and even without any personal code of my own, if I try to compile the exact same build, the USB middleware overflows my FLASH memory by a ton.  I am only using I2C and USB peripheral in my project.Does this seem abnormal? Am I doing something wrong?  It doesn't seem right to me that these add-ins themselves should be enough to overflow the FLASH memory size when I haven't even written a single line of code.  Are there any steps you usually take to optimize the code?   

STM32H753 UART Baud is 15% low. I set it to 115200, but it's running at 98400. Is this a misconfigured clock?

Hi, To emulate the behavior of cell added in AEK-POW-BMS63EN board, we used voltage divider circuit (36 V, 10 5ohm resistor)and used the voltage drop of each resistor as input to C0......C14. For some days comm. timeout led was being turn on for 60 seconds whenever power on the supply, and work correctly to get voltage, current, temperature measurement and also balancing was working. But once balancing was turn on (due to voltage divider circuit voltage and current will increase for every i/p c0...c14) after that whenevr we power on supply, comm. timeout led was only glowing for very short duration, and now now no voltage or current measurement is possible as it just timeout before any communication.Is there any way to make its timout time for 60 seconds as it was.or Is the IC got damaged due to cell emulated ciruit. ? Thanks and regards,bitBuddy 

Colleagues,What should be done in firmware for VBUS detection through a GPIO pin?  My device is self-powered, so I have to do VBUS detection. The device is built around STM32G474, and it doesn’t have a dedicated pin for VBUS detection, so I have to do it through a GPIO pin and firmware.  VBUS is connected to the GPIO pin PA10 through a 2x 100kΩ divider.I checked the code examples for STM32G4, but I couldn’t find examples for USB.  If somebody could point me to a code example, that would be great.I’ve read this FAQ on VBUS detection which is a collection of excerpts from AN4879 (and I’ve read the app note too). [without dedicated hardware VBUS detection pin] Any 5V tolerant pin with external interrupt functionality [...]Does the VBUS detection have to be done in an interrupt? Or can it be done in the main loop? If it can be done in the main loop, then are there timing constraints? "However, the disadvantage of this solution is that the software handling of VBUS

Hi friends,I have to configure Sleep mode  and Wakeup mode in  STM32F103C8T6 and STM32F407VET6 using RTC .But i  did not know how to configure this process .I need your guidance how to configure this by using datasheet and one important point is i have to use only internal clock for my configure. Thank you for advance for yours response

   /* add the network interface (IPv4/IPv6) with RTOS */ netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &tcpip_input); /* Registers the default network interface */ netif_set_default(&gnetif); if (netif_is_link_up(&gnetif)) { /* When the netif is fully configured this function must be called */ netif_set_up(&gnetif); } else { /* When the netif link is down this function must be called */ netif_set_down(&gnetif); } /* Set the link callback function, this function is called on change of link status*/ netif_set_link_callback(&gnetif, ethernet_link_status_updated);  I am using open source lwip.c and I realized my ethernet connection breaks and reconnects time to time. I was wondering if it is okey or expected behaviour in ethernet connections or it shouldnt be disconnecting at the first place.

Hi,I'm using Nucleo-STM32WL55JC1. I used a coin cell to give power to Vbat and remove the sb21 link.Now I tried the LSE as an RTC source and time works as expected even after I remove power from Vdd, I have used HAL_PWR_EnableBkUpAccess();But when I tried to USE LSI crystal time is resuming from the last power removed but not the actual time.for example, if I removed the power at 15:51:21 and resumed power after 5 minutes it shows 15:51:22 instead of 15:56:21.I want to use LSI only because I don't want to have an external RTC with my board when I'm designing the customer board.my doubt is if LSE works, even LSI also should work. as we can see in the diagram both LSE and LSI are in the same Backup domain. Please let me know if anything missing. Thank you in advance!!!

When changing the timebase source in CubeIDE from Systick to any peripheral timer (TIM6 in my test case), the timer is set up in HAL_InitTick() called from the HAL_Init() function, which is the first function that is called in main().HAL_InitTick() uses several calls to get the clock configuration from RCC in order to set up the timer.However, the clocktree is configured only AFTER the timer has been initialized, since SystemClock_Config() is the second function called in main().This should mean, that the peripheral timer that provides the system clock is based on uninitialized clock settings. The simple solution is to swap SystemClock_Config() and HAL_Init() in main(), so clocks are configured first and the timer afterwards.Am i missing anything, or is this a bug? Setup:STM32F427VGTxCubeIDE 1.16.0STM32Cube FW_F4 V1.28.0Selected Timer for System clock source: TIM6My .ioc file is attached.

Hi,I'm trying to create a wrapper for STM32CubeProgrammer_API.dll.The program crashes on trying to use the obDisplay API. I've tried using STM32CubeProgrammer_API.dll versions 2.10 and 2.15. Is there something I'm missing?Thank you very much.

Hi all,When I wake up from Standby mode and reinitialize the pins and peripherals, they still don't work. Below is my STBY_SysHwRestore() routine, where I reinitialize clocks, pins and peripherals, but the rest of the code does nothing when they accessing the pins and peripherals. I have looked into the BLE_HeartRate example and copied the CPUcontextSave and CPUcontextRestore from the start up file. What confuses me on the BLE_HeartRate example is that it doesn't need to reinitialize clocks when leaving the standby mode, while on my application it needs, otherwise it get weird behaviour. QUESTION 1: What is the correct way to reinitialize pins and peripherals when waking up from standby mode?QUESTION 2: After waking up from standby mode due to a wake-up timer (registered on the hw_timerserver.c module), if I start a task on the sequencer directly from the wake-up timer callback, the CPU hangs for some reason. This stuff is really h

Hello, I would like to report a bug on USB CDC middleware generated from CubeMX 6.11. When I use it in Debug build, everything works as expected. Once I switch to Release, the compiler optimizes out the serial number.  I use official VScode extention with Cmake to build the FW.Without a serial number at USB device, Windows fails to recognize that anything is connected. It works in Linux only. I have the same issue happen at STM32F411 and STM32L433. The solution was to add initalization to 3 lines in USB_DEVICE\App\usbd_desc.c uint32_t deviceserial0 = *(uint32_t*)DEVICE_ID1; uint32_t deviceserial1 = *(uint32_t*)DEVICE_ID2; uint32_t deviceserial2 = *(uint32_t*)DEVICE_ID3; I hope this helps someone and the STM may fix it. No support is needed.Thanks.

 Is my settings true?
