The datasheet say:USB on-the-go high-speed (OTG_HS)     The devices embed an USB OTG high-speed device/host/OTG peripheral with integrated transceivers. The OTG_HS peripheral is compliant with the USB 2.0 specification and with the OTG 2.0 specification. It has software-configurable endpoint setting and supports suspend/resume. This interface requires a precise 60 MHz clock that is generated from the internal USB PHY PLL (the clock source must use a HSE crystal oscillator).    But now I have tried it, it is also possible to use HSI as the clock source, is this a special case or can it indeed be used as the clock source? If the product is released in batches and the HSI is used as the USB HS clock source, will it often fail and the yield rate is not high? 

I am using Zigbee for wireless communication using Zigbee_OnOff_Router_NVM as a reference. The problem I am currently facing is that if I turn off the Router for a long time, it may take about 20 seconds for the data to reach the Coordinator the next time it is started. What can I do to reduce the time it takes to reconnect? Help me.

Am testing the x-cube-sbsfu on H7A3 (using H7B3 project with OTFDEC disabled).  After enabling SFU_MPU_PROTECT_ENABLE, I always ran into mem manage fault when the function HAL_RCC_GetPCLK1Freq is called during HAL_UART_Init: An MPU or Execute Never (XN) default memory map access violation has occurred on an instruction fetch (CFSR.IACCVIOL, MMFAR). The MPU setting for RCC is as below:/*** @brief Region 1 - Enable the read/write operations for RCC peripheral area in privileged mode.* Execution capability disabled* Inner region inside the Region 0*/#define SFU_PROTECT_MPU_PERIPH_2_RGNV MPU_REGION_NUMBER1#define SFU_PROTECT_MPU_PERIPH_2_START RCC_BASE#define SFU_PROTECT_MPU_PERIPH_2_SIZE MPU_REGION_SIZE_1KB#define SFU_PROTECT_MPU_PERIPH_2_SREG 0x00U /*!< All subregions activated */#define SFU_PROTECT_MPU_PERIPH_2_PERM MPU_REGION_PRIV_RW#define SFU_PROTECT_MPU_PERIPH_2_EXECV MPU_INSTRUCTION_ACCESS_DISABLE#define SFU_PROTECT_MPU_PERIPH_2_TEXV MPU_TEX_LEVEL0#define SFU

I have a small amount of per-device data (e.g. hardware revision, serial number, manufacture date) that I would like to store persistently in an STM32G030 without consuming a 2K flash sector.  Obviously one option is OTP, but I'm curious about the Flash Option bytes and have a few questions:1. What option byte addresses (if any) are available to hold user data.  The manual indicates that there are 128 option bytes at 0x1FFF7800, writable as 64-bit double-words.  The manual also shows a memory map listing the purposes of bytes 0x1FFF7800..0x1FFF782F, but no information is given about locations 0x1FFF7830..0x1FFF787F and I'm hoping those are available.This site (https://wiki.segger.com/ST_STM32G0) indicates that the STM32G0x0 only has 96 option bytes from 0x1FFF7800 - 0x1FFF785F rather than 128; I don't see anything about this in the manual; is it true?  In that case, the available range might be 0x1FFF7830..0x1FFF785F. From a stock uC, I note that the words at 0

Hi,I am getting warning as build output as below. phaseBegin and phaseEnd is of type uint16_t. But, I typecast it as pointer variable to point uint8_t, because HAL_I2C_Mem_Read expects that argument to be pointer to uint8_t data.My code is here.Could you please help me resolve ? 22:02:55 **** Incremental Build of configuration Debug for project PCA9685 **** make -j8 all arm-none-eabi-gcc "../Core/Src/PCA9685.c" -mcpu=cortex-m4 -std=gnu11 -g3 -DDEBUG -DUSE_HAL_DRIVER -DSTM32F407xx -c -I../Core/Inc -I../Drivers/STM32F4xx_HAL_Driver/Inc -I../Drivers/STM32F4xx_HAL_Driver/Inc/Legacy -I../Drivers/CMSIS/Device/ST/STM32F4xx/Include -I../Drivers/CMSIS/Include -O0 -ffunction-sections -fdata-sections -Wall -fstack-usage -fcyclomatic-complexity -MMD -MP -MF"Core/Src/PCA9685.d" -MT"Core/Src/PCA9685.o" --specs=nano.specs -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb -o "Core/Src/PCA9685.o" In file included from ../Core/Src/PCA9685.c:9: ../Core/Inc/PCA9685.h:26:9: note: '#pragma message: i2c

I am migrating a project from STM32F373 to STM32G473. I can program the new part successfully, but I don't see PWM . The PWM values are written in user created code and I can read them back via the STLink, so I know that the part at least begins running. I'm not sure if there are new settings that may be defaulting to the wrong values that are preventing outputs. (I see only 0v for PWM) I configured everything via CubeMX and I added the below user code to enable the timer  What might cause me to not see any PWM output?HAL_TIM_Base_Start(&htim8);HAL_TIM_PWM_Start(&htim8,TIM_CHANNEL_3);HAL_TIM_PWM_Start(&htim8,TIM_CHANNEL_4);  

Hello The STM32CubeIDE Version: 1.15.0 doesn't create the code for me because I can't login in the software persistently can't connect to the internet. I followed some advice found on this community thread https://community.st.com/t5/stm32cubeide-mcus/myst-login-issue-in-stm32cubeide/td-p/575447 but to no avail. What can I do ?

Hello,I am currently trying to implement an ASPEC Controller in C# to communicate with a motor control dev board over the UART (essentially, creating motor pilot with the ability to modify as needed).  So far, I have implemented Beacon and ping packets.  Beacon packets work perfect.  When I do a ping packet, the return data seems garbled. The code is designed to not process any packet that doesn't have a valid header CRC. I tested this by manually corrupting the header, and I no longer saw output from my packet detection, which suggest to me that I am receiving what the devkit is trying to send.I programmed my code to output debugging information every time a valid packet is sent or received.  I have attached the output of my code.  It starts with 2 pairs of beacon packets to negotiate buffer sizes.  I then start sending 4 ping packets per second with consecutive packet numbers.For the ping packets, I am expecting to get back the same packet, except f

Hello,I'm encountering an issue with STM32CubeMX while configuring the STM32U585QII6Q microcontroller. Specifically, when attempting to configure PD11 to ADC4_IN15, I find that the ADC4 channels are grayed out or inactive.While using STM32CubeMX, I can assign PD11 as ADC4_IN15 in the pinout view, but it remains orange (not configured). However, in the "ADC4 Mode and Configuration" pane, I am unable to configure it.For the STM32U585QII6 variant, I can configure ADC4_IN15 without any issues. However, in the case of STM32U585QII6Q, I encounter this problem.I have reviewed the datasheet, but I couldn't find any reference to different ADC settings between these variants.Could it be that the Q variant does not support ADC4 channel 15, or is this possibly an issue with STM32CubeMX?Thank you.Ari

We have recently bought the STGAP2SMTR from DIGIKEY. The pictures of the same is attached to this. I am unable to figure out which pin is pin number 1 (there is no DOT in the IC). Please can you look at the pictures and let me know which is the pin number 1 in the Gate driver IC (STGAP2SMTR). Thank you

Hi,I am trying to add HAL_I2C_Mem_Read into my application. However, when I write the API in the region below, it is not auto filled, I can not use the API. On the other hand, when I add the API inside the above function it works.How can I fix this ?I have already added #include "stm32f4xx_hal_i2c.h" as header file.Thanks.    

  Hello to everyone. I'm working on a display interface, changing from M3 -> M4 -> H5 CPUs. The issue appeared on all type(it's a HW issue?) At the beginning I can connect, debug, program and so on. Bt after some operation, I can't continue. I still have a "No STM target found" error, from CubeIDE and Programmer. What I can see is that the CPU voltage is not 3.3V, but less:   This happen with different STLINK-V2 or V3. Obviously I check the volts on SWD pin 1 and it's always ~3.3V When this happen I usually pas to another board/JTAG. But afer a while I connect the old JTAG-Board and it work again. I enclose the schematics, because I presume it's a HW problem. Can someone gimme a tip? Thanks.    

Hi everyone,Designing the BLE (bluetooth low energy) part of my software, I have to use BlueNRG-1, BlueNRG-2 DK SW package.First of all, I included by hands the library file (.a).But there is a lot of source-code that is not provided in the library (but in others files), I then decided to include manually headers file and others source code files (.c). Dont know if its a good practice.Are their others options instead of manually including .a, .h and .c files ?I recently realized that new versions of source code was available, and manually do migration every-time is error-prone and long to do.Thanks for advice !

Hi,I am using the nucleo-H503RB I3C (Controller mode) with this example to connect to an I3C standard chip. The sensor transmits IBI with 5 bits of payload but I noticed that the STM32 receives only 4 bits, and then it stops receiving the fifth bit.Is there any method I can define the receive IBI payload size on the controller side? Any kind of help is appreciated. :)

Hi I'm trying to run SPI_FullDuplex_ComIT_Master and Slave examples that use SPI1 on NUCLEO-H563ZI boards.The pin connections in the read me seems to be inaccurate i.e1. There is no PA5 on 10th pin of CN6 on the Nucleo but it is there on CN7.2. There is no PA7 on pin 15 of CN5 but it is there on CN12.Layout Reference: hereSo, I referred to NUCLEO-H743ZI and used the SPI1 pins and tried to use these connections on my NUCLEO-H563ZI and the example started working.So, is the example not updated or is the layout inaccurate?Can anyone provide a pin diagram like NUCLEO-H743ZI for NUCLEO-H563ZI too?   

Hi ST Support Team,I am reaching out regarding an issue I have encountered while attempting to utilize USB CCID functionality on the STM32WB55 MCU. Recently, I integrated the CCID driver from the following link into my project.https://github.com/STMicroelectronics/stm32_mw_usb_device/tree/master/Class/CCIDFollowing the integration, I successfully configured the USB device, and my system(windows PC) can now detect the STM32WB MCU as a smart card reader.However, upon further testing, I encountered an unexpected behavior: when attempting to communicate with the smart card reader using a Python script, the STM32WB USB port is detected as a Virtual COM port rather than a smart card reader. As a result, I am unable to establish communication with the MCU via script.I am reaching out to kindly request your assistance in resolving this issue. Could you please provide guidance or solutions to ensure that the STM32WB MCU is correctly detected as a smart card reader and able to communicate w
