What is the difference between the marking "SH" and "S2" for the part number LSM6DS3?Please advise if the correct top marking SH" and "S2" are both valid. Thanks

Hi ST,I follow this video to implement my USB HID Project https://www.youtube.com/watch?v=3JGRt3BFYrM&ab_channel=STMicroelectronicsOn the Win7, it work perfect, but when I use Win10 as PC Host, it cannot workjust like bellow picture    Please Help me to fix this issue :downcast_face_with_sweat: thanksTony Wu

I wrote some software that reliably measures the number of memory cycles required to retrieve 16 and 32-bit operands from the Cortex-M4 memory. When a 16-bit operand fits within a 32-bit physical word, I would have expected that only a single memory cycle would be necessary to read or write the data, but that's apparently not the case if it's in the MIDDLE of a 32-bit physical word. And when a 32-bit operand is stored at an address off by 1 or 3 from being word-aligned, it takes THREE cycles (instead of the expected two). Take a look at the attached summary of results. Can anyone explain why the results are not as expected (as shown in red)?Thanks!Dan

Hi,I would like to use USB Type C for powering a microcontroller board with a STM32L476JG dedicated to driving different types of piezos. Depending on the driven piezos the overall power consumption of the board can reach up to 8 W.I came across the TCPP01-M12 datasheet demonstrating a circuit for up to 15 W (5V/3A) of power in conjunction with microcontrollers without USB C Power Delivery hardware which nearly perfectly fits my requirements: However, my problem is that I am nearly running out of free microcontroller pins and therefore I'd like to know whether it is really necessary to implement one ADC channel for sensing the VBUS voltage and one GPIO for enabling or disabling the VCC of the TCPP01-M12 as they are not marked as "not mandatory".I understand that the GPIO1 is used in order to let the TCPP01-M12 start in dead battery condition but as far as I understood the way USB Type C without power delivery works is that in principle I just have to pull down both CC lines with a

hey thereI try to receive some characters using UART and here is the confighuart1.Instance = USART1;   huart1.Init.BaudRate = 4800;   huart1.Init.WordLength = UART_WORDLENGTH_8B;   huart1.Init.StopBits = UART_STOPBITS_1;   huart1.Init.Parity = UART_PARITY_EVEN;   huart1.Init.Mode = UART_MODE_TX_RX;   huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;   huart1.Init.OverSampling = UART_OVERSAMPLING_16;  I use HTerm as a serial terminal to send data to it. I set the Baud rate to 4800, Data length to 7bits(I used CubeMX config, there it indicates the word length is parity included, so 8bits means 7bits+1parity I guess), and 1 stop bit and parity as EVEN. things go wrong for some characters: for example 0xAF and 0xC5 are received as 0x2F and 0x45 respectively. some other characters are received OK such as: 0x41 or 0x00.. why is that? I noticed that the error is happening in the last bit of the faulty bytes, why is that?

We have a wide-input power management ic with buck-boost converter. 28V VBUS is not a problem. So is it possible to eliminate the N-MOSFET (at least in Sink mode)? If it is OK, what is your recommendation for connections of IN_GD, Gate, and Source pin?

As of version 1.1.0 of X-CUBE-SUBG2, file app_x-cube-subg2.c contains two uninitialized pointers. typedef struct { uint8_t Cmdtag; uint8_t CmdType; uint8_t CmdLen; uint8_t Cmd; uint8_t DataLen; uint8_t* DataBuff; // This pointer }AppliFrame_t;DataBuff of two instances of AppliFrame_t, xTxFrame, xRxFrame, were operated on without initialization. for (xIndex = 5; xIndex < cRxlen; xIndex++) { xRxFrame.DataBuff[xIndex] = pRxBuff[xIndex]; }for(; xIndex < xTxFrame->DataLen; xIndex++) { TxFrameBuff[xIndex+5] = xTxFrame->DataBuff[xIndex]; }As a result, the example basically doesn't work. System will just crash upon running. Tested on several NUCLEO boards, F411RE, F070RB, but judging from source code, other nucleo boards will be affected as well, including L152 and L052 boards which are supposedly fully tested.Given S2-LP radios are basically brand new, we spent hours and hours making sure we followed the instruction correctly to no avail before we started to check the

I was hired to program the STM32MP151 dual core processor. I loaded the STMCoreIDE because that was what was recommended. Not being familiar with the Arm M4 I decided to buy a Nucleo to learn how the ST Peripherals worked in what I hoped would be a simpler environment. But the UM1727 does not list the STM32CubeIDE as one of the supported IDEs. Where do I find instructions and code to test? I am running Linux Mint 20.1.

There are two ways of BLDC motor solution. The one of solutions is EVSPIN32F0601S3 and the other is EVSPIN32F0601S1. I want to drive BLDC motor with sensor less. Which solution is match the goal? The motor specification is 100V D.C. 1A 100W.

I'm using the STM32G431 MCU to run a BLDC motor with the middleware FOC code. I'd like to be able to report the bus voltage in the system but haven't been able to find the way to access the code. I found a procedure declared in bus_voltage_sensor.c, __weak uint16_t VBS_GetAvBusVoltage_V( BusVoltageSensor_Handle_t * pHandle ) but the input is the pointer BusVoltageSensor_Handle_t*pHandle. I'm guessing this is a pointer to a structure for my motor but I don't know where it is defined.Is using the procedure VBS_GetAvBusVoltage_V the correct approach or is there a different method to use, something closer to the UI interface?Thanks,Brian

Hi, I read a press release that STM32Cube IDE had added thread debug functionality. I have a project that uses FreeRTOS 10.0.1 with trace facility enabled. I am hoping to leverage the FreeRTOS debug tool to aid in my development but at this moment I am not sure how to enable it within the debugger view. I am using STM32CubeIDE Version: 1.5.1. My project is not based on CubeMX directly but I could generate new files if needed. Thanks!

STM32CubeMX (STM32Cube_FW_F0_V1.11.2) allows option for One Pulse Mode for TIM14. Does TIM14 actually support OPM on STM32F031G6U? In Reference Manual (RM0091 rev 9), TIM14_CR1 does not have bit 3 OPM. Is mistake in Reference Manual or in STM32CubeMX?

Hello,this is not the first time i set touchgfx in a custom board (with STM32F767 MCU). I always followed the method described in the touchfgx documentation, which can be summarized in this video guide.Now i'm trying to get it to work with STM32H743 MCU. I tested first the framebuffer in the internal and external ram respectively, following the official documentation. Once working, i enabled touchgfx 4.16 (i'm using CUBEIDE 1.5.1), i enabled CRC and FreeRTOS v2 and i inserted MX_TouchGFX_Process() inside the GUI Task.When i debug it returns HardFault, but if i remove the MX_TouchGFX_Process() function it debugs without problems, but obviously nothing happens.I tried to use __HAL_RCC_CRC_CLK_ENABLE(); before initializing Touchgfx, but nothing.I also noticed that the "Generate Under Root" checkbox is checked and i can't uncheck it, while the official documentation says to uncheck it.Cane someone help me?Thank you.

Hi,In debug mode, is there a way to reload the MCU flash but not the external flash connected to the QSPI?It takes a while for CubeIDE to reprogram the external flash.I do not modify the external flash data between debug sessions, so it would save me a lot of time if it was not erased then reprogrammed every time.I could not find an option to avoid the external flash reload.Thanks.

Hi,I am designing Obstacle Detection Sensor for AGVs. I have following requirements:Ranging Distance : 5-8mRanging Frequency: 30HzFoV: 135 degree with multiple sensorsI have gone through Vl53L1X and Vl53L1CB sensor, i found that ranging distance of 8m is possible with Vl53L1CB sensor in Ranging Mode. Is it possible in indoor environment?Along with this what will be output of Vl53L1CB sensor? Will that be distance of detected object?What will be affect of ambient light on ranging distance?Vl53L1CB GUI is accessible through F411RE Nucleo Board or not?Please resolve my queries so that i can proceed furtherRegardsAkansha Verma

Hi,I use a X-NUCLEO-NFC06A1shield and a Nucleo-476RG to read a NFC chips ( M24LR64D-W or M24LR04).For my test I use the demo program from ST provided with the shield.I want to read 32 blocks (a block is 4 bytes) with the function rfalNfcvPollerReadMultipleBlocks.If the numOfBlocks parameter is set to 31 the function works correctly.If the numOfBlocks parameter is set to 32 the function returns ERR_REQUEST.Could you help me to resolve this issue?Thx & RegardsNigorosNote 1: The chip M24LR04 is on a red board M24LR-discovery.Note 2: To read the chip M24LR64D-W I use the function rfalST25xVPollerM24LRReadMultipleBlocks with the same issue.

Hello,i would like to start a project with a STM32H743, a 4 "TFTDisplay and STemWin. The sDisplay works perfectly via FSMC. Now I have downloaded the STM32Cube_FW_H7_V1.8.0. Which Lib should I use? In old versions they were marked with GCC. Now with w16 w32 etc.Greetings Sascha

Hello,I want to download sample code from this page: https://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/backend-communicationBut I don't think the links are working, for example:http://sw-center.st.com/touchgfx/TouchGFX/knowledgebase/hw_integration_tasks_exti.4.9.3.zipDoes not download the zip. I think the links maybe broken again.Is there an updated link we can use to get the example code?Thanks!

For some reasons it will be good to write my own MCU serial number for USB purpose.. Is it possible to change seria number of hte MCU and how to do this...

Hi Guys,Im struggling in getting a good way to work with cubemx and multi channel ADC. I want to be able to only change the cubemx file whenever there is a hardware change. Currently i cannot do so because in my firmware i am using HAL_ADC_ConfigChannel() to change adc configurations (i have 5 channels and need 3 to sample at the same time at the max speed, other two i sample seperatly and later on). However the ADC_ChannelConfTypeDef.Channel needs to know the ADC channel.Does Cubemx have a way to create variables for adc channels (currently i use variable ADC_CHANNEL_x ) ? Or is there a way to grab the channel from a user label?Kind regards,Taxara

Hey guys,I am trying to communicate with S25FL064L Cypress Flash and almost for one week I cant reach the redec ID , I checked the hardware, and communication with digital analyzer just with S25FL064L no any hardware.Tried the HAL library , checked the websites and compare with my codes, I couldn'd find a mistake, so where is my mistake now.Thank you for answers and spending time.These are codes related.int main(void) { LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_SYSCFG); LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_PWR);   SystemClock_Config(); // 0xEBFF FCFF for port A // 0xFFFF FFFF for the other ports // I have read some info from the users and that is why this code is below CLEAR_REG(CS_FLASH_GPIO_Port->MODER);   MX_GPIO_Init(); MX_SPI1_Init(); MX_SPI2_Init(); MX_USART1_UART_Init(); MX_USART2_UART_Init(); MX_ADC_Init(); MX_RTC_Init(); MX_I2C1_Init();   LL_SPI_Enable(SPI1); }   void read_Jedec_ID(uint8_t *p) { LL_GPIO_ResetOutputPin(GPIOA, LL

For an application, I need to implement FOTA through UART/USB for STM32L0 microcontroller. Are there any examples or firmware packages available for this?

Both these functions contain the code:"if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT)"However SDMMC_DATATIMEOUT is defined as 0xFFFFFFFF so the timeout is very long (49 days with a 1ms tick) and therefore never occurs.That upshot is that if there is ever an error with the Status-send or Find-SCR functions (which can occur occasionally) then the caller is blocked indefinitely and no further comms with the SD card is possible.Suggest that these instances should use SDMMC_CMDTIMEOUT not SDMMC_DATATIMEOUT because SDMMC_DATATIMEOUT is defined for use with SDCLK ticks not OS/HAL ticks.
