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.

In STM32CubeMX (6.1.0) for STM32H7 the I2C parameter settings allow you to enable Custom Timing. However, the Timing parameter still remains disabled and cannot be set. I would expect that for custom timing, the user could change the Timing parameter.I'm also wondering why other MCUs (e.g stm32f0) don't even offer a Custom Timing.

Hello,I search information on the managment of the DMA transfert to the timer.I use the TIM1 and TIM8 to generate 3 PWM output on each of them. The six output are synchronized.I want to use the DMA to update the timer value, rated on 28µs.I don't know if I must select TIM1_CH1/CH3/CH3 on the DMA Resquest or if I must select the TIM1_UP ?what are the difference between this two possibility ?thanks in advance.

Hi,So far in AbstractDataGraph.cpp the library had:namespace touchgfx { AbstractDataGraph::AbstractDataGraph(int16_t capacity) : dataScale(1), alpha(255), topPadding(0), leftPadding(0), rightPadding(0), bottomPadding(0), maxCapacity(capacity), usedCapacity(0), gapBeforeIndex(0), clickAction()but it should be:namespace touchgfx { AbstractDataGraph::AbstractDataGraph(int16_t capacity) : dataScale(1), alpha(255), topPadding(0), leftPadding(0), rightPadding(0), bottomPadding(0), maxCapacity(capacity), usedCapacity(0), gapBeforeIndex(0), clickAction(), dragAction()i.e. the problem was that "dragAction" was never initialized and our application would crash. But not every time you dragged a Graph widget, but only sometimes (when you enter that screen and everything is initialized for maybe the 2nd or 3rd time, then with the wrong garbage data, it would crash)Here is our stacktrack where it would always crash. dragAction->isValid() would be called, even though dragAction was never initi

Hi!A question related to the 32 bit TIM2 (or timers in general).I am generating a square wave output using TIM2 Output Compare function with toggle mode.I have also configured the DMA to help switch the CCRx output compare value in order to go from low to high, and high to low again within a each timer period. At least that is want I want to achieve.However, the DMA seems to be triggered at when each timer period is finished and not when each compare has happened. Should it not do this? According to the STM32G4 reference manual, it look like the DMA request should happen after a compare as I expect but not how it is happening? My timer CUBEMX configuration is as following. The system clock is set maximum 170MHz. Prescale set 0, period is set 170000000-1, so I expect the square puls to be generate 1 time per second. Instead it is generate everyother second.This is my code initialization of the timer with the DMA buffer:#define MOTOR_DMA_OC_HIGH 0 #define MOTOR_DMA_OC_LOW 10  

Hi all,I am new here and to STM32 in general.Does the STm32F401CE comes from the factory with a DFU bootloader?If so, does a full chip erase with the CubeProgrammer and a stlink v2 erases that factory bootloader?.If so, is the binary of the factory bootloader available so it can be flashed back into the device? I can't get the DFU bootloader recognized by the CubeProgammer, if it's because of the full chip erases I performed, I wonder if I can program the stock bootloader back. Below is a snapshot of a memory dump of of the bootloader area, I think. I am using STM32F401CE with a 25Mhz external crystal, and everything else works.

I took the "Examples\UART\UART_Printf" as reference and added the EmbOS. Printf worded with embOS. In some steep, after project clean or some project changes, the printf stopped to work.Uart works. I use STM32CubeIDE.What can be a reason?

Hi.

I wanted to replace my system that used to work with stm32f407VGT6 with STM32H723VET6 as it is cheaper.I designed a new pcb, followed the steps in the link below and created a project.https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-workingI got hardfault every time I compile the code and throw it to the processor.While reviewing the processor datasheet, I saw that the ram areas he suggested to use in the example were 16KB instead of 128KB in the STM32H750.Default address of LWIP_RAM_HEAP_POINTER (RAM Heap Pointer) 0x30044000 corresponds to non-existent memory in STM32H723VET6each time I got HardFault from the function below.StartDefaultTask MX_LWIP_Init tcpip_init lwip_init mem_initDoes anyone have any suggestions about problem?

I have bought this product set.https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/stm32-nucleo-expansion-boards/p-nucleo-lrwan2.htmlI can connect to its gateway through virtual serial Tera terminal. Also it can connect to Loriot gateway server.However, the sensor node board with the USI I-NUCLEO-LRWAN1 shield does not respond to AT command through a Tera terminal. Also, the Cayene application does not show any activity of this sensor board.How do I correct it?

Hey folks,I am trying to use BSP package for recording audio on stm32h747 discovery board. I created a project from scratch and tried to do what ever I saw in the BSP exam for the board. However, "BSP_AUDIO_IN_TransferComplete_CallBack" function is never called really. I am wondering if there is some hidden things that I need to do for the callback. I can also provide my project files if it is necessary.Thanks,

Please note: what I am describing is my experimentation to try to figure out how all this works. Yes, there are likely things you wouldn't do in a real life situation, but I want to understand all the edge cases.Also note, I am not using a HAL or library (I am actually using Rust, but that shouldn't matter), so all the details I describe directly relate to registers. Please don't suggest how to "fix" my issue by using a HAL or library.And finally, all help is GREATLY appreciated, I've been banging my head against the wall for days on this now!Here goes...Timer is the 32bit TIM2It is set up so each TIM2 CNT increment = 1uSBut I'm only using 16 bits (again, for test purposes), so ARR = 65535I manually increment CCR1 by 110 in my TIM2 interrupt handler on each valid interruptI filter the interrupt handler on SR.CC1IF = 1The OC mode is "frozen", I am not using the microcontroller to control the output pin for meTest goal: To toggle an output pin in my TIM2 interrupt handler using Outp

Hallo i´m using STM32F107 and i want to choose in STMCubeMX the TIM6 for triggering the adc in specific times for measuring. My Problem is that i can´t select TIM6 for triggering. What i don´t find is why. In the manual and so on is this possibility is even explicitly mentioned. But how I have to parameterize it?
