Hi,I'm using STM32CubeIDE 1.14.0, I have multiple projects in "Project Explorer", one of it is my default active project and now how do I set another project as the default active project? For example, I have project_1, project_2, project_3, project_4 and project_5 in "Project Explorer" window, assume project_1 is the default active project and how do you switch to project_3 as my default active project? Best Regards,James Shih

Hi @everyoneIn the below IIC API HAL_StatusTypeDef HAL_I2C_Mem_Read(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout)uint16_t MemAddress will accept only hexadecimal value or it will accept decimal value also.    

Hi,I'm using a CR95HF NFC reader using the SPI. I have Hibernate mode problemI'm sending a command :CR95HF_Send(0x07, 14, 0x08, 0x04, 0x00 , 0x04 , 0x00, 0x18 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00);If the tag is in the field then I can go into Hibernate modeIf the tag is not in the field then I cannot switch to the Hibernate mode.The generator remains on. Current consumption. How to correctly switch the CR95HF to mode Hibernate? Thanks From Ready state to Hibernate state and back to Ready stateIn Hibernate state, most resources are switched off to achieve an ultra-low powerconsumption.The only way the CR95HF can wake-up from Hibernate state is by an external event (lowpulse on pin IRQ_IN).A basic Idle command is:>>>0x07 0E 08 04 00 04 00 18 00 00 00 00 00 00 00 00 https://www.st.com/content/ccc/resource/technical/document/application_note/93/7e/d9/bc/44/d4/40/d4/DM00034250.pdf/files/DM00034250.pdf/jcr:content/translations/en.DM0003425

I am experimenting with the USB HS peripheral on the STM32U5A9NJ Discovery Kit, and noticed that there is a signal called VBUS_SENSE which is routed to PG1 (ADC4 IN8). I've configured ADC4 to sample from this pin, and notice that the sensed voltage is ~0.14V with the USB connected, and 0.0 with the USB disconnected. Is this the expected behavior? I would have expected to see a higher voltage with the USB cable connected. What is the maximum possible voltage for VBUS_SENSE? My ADC resolution is set to 12 bits, sampling time is 814.5, and Vref+ is 1.8.

Is there any function I can use to calculate the yaw and pitch directly from the IMU? Or do I need to find the quaternion(SFLP) and then calculate Euler's angle on my own? 

Where can I get schematics for these 2 dev boards in pdf format.  I found a link to the cad resources but they do not contain pdf or any recognizable format. Thanks in advance for your help !!!

Hi, how can i take values of the iks01a3 sensor (in particular LSM6DSO) in CubeIDE (or Arduino IDE). The value of the angle, and so on.

Hi,I'm currently attempting to make my first Starter Package flash on STM32MP157D-EV1 by following this guide:https://wiki.st.com/stm32mpu/wiki/STM32MP15_Evaluation_boards_-_Starter_Package However, it seems that the TSV "trusted" folder is missing in en.flash-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz package. Thus, the following command gives an error: STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/trusted/FlashLayout_sdcard_stm32mp157c-ev1-trusted.tsvError: The file FlashLayout_sdcard_stm32mp157c-ev1-trusted.tsv does not exist, please check the file's pathError: TSV flashing service failedI also see that the file exist in the previous package v5.15.Is their an issue with the 6.1 package or I missed something? How can I fix this?Thanks in advance.

Hey,I am developing a project in which the M7 core has CAN and USART communication which constantly communicates with components, the M4 core has Ethernet communication.I was interested in checking what the rate of the main loop is, so I defined two variables of type double that perform the following operation in every main loop:I display b7 in STM32CubeMonitor, and that's how I see how long it takes for 100K main loops, or how many main loops are performed per second.Clock Configuration:I did the test for the Core-M7 and the Core-M4, and these are the results:Core-M7:About 1.666M loops per second. Core-M4:About 60K loops per second. The results are so far from each other (I expected a 2x ratio between them).I started from the assumption that the Ethernet communication is the one that causes the slowing down, therefore I lowered the Ethernet communication and still got almost identical results.I opened a new project (No code except the test) and ran the same test for eac

I'm trying to maintain a directory structure in my CubeIDE project that contains an import of a third party repository, however the directory is erased when I regenerate the drivers after saving changes to the .ioc file.  I'm using Azure RTOS which conveniently creates a 'Middlewares' directory inside which I added a new directory called 'Third_Party'.  Sometimes the ioc build leaves it alone, but most times it does not.  Is there a way to prevent erasure of the directory?

Hi,I've been following along with the "Getting started" on the wiki, but I cannot set up the developer package for my STM32MP157x-DK2. Downloading the file and trying to extract the archives, I get the following:```adriaan@ZOBLZO21X5GY3:~$ cd STM32MPU_workspace/tmp/adriaan@ZOBLZO21X5GY3:~/STM32MPU_workspace/tmp$ lltotal 667536drwxr-xr-x 2 adriaan adriaan 4096 Jan 6 16:49 ./drwxr-xr-x 4 adriaan adriaan 4096 Jan 5 16:23 ../-rw-r--r-- 1 adriaan adriaan 262113357 Jan 6 16:45 en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz-rw-r--r-- 1 adriaan adriaan 50 Jan 6 16:45 en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz:Zone.Identifier-rw-r--r-- 1 adriaan adriaan 421422061 Jan 6 16:46 en.flash-stm32mp1-openstlinux-6-1-yocto-mickledore-mp1-v23-06-21.tar.gz-rw-r--r-- 1 adriaan adriaan 50 Jan 6 16:46 en.flash-stm32mp1-openstlinux-6-1-yocto-mickledore-mp1-v23-06-21.tar.gz:Zone.Identifieradriaan@ZOBLZO21X5GY3:~/STM32MPU_workspace/tmp$ tar xvf en.

Hello, I'm using an STM32H750 and I need to implement a single small dynamic bitmap, but I have only ITCM RAM available. I read and made all the code from the articlehttps://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/dynamic-bitmapsbut the funcion Bitmap::dynamicBitmapCreate return INVALID.The question is: is it possible to use ITCM for this purpose? I'm using IAR 8.32 Thank you

Hi I've been searching for some info about these two MCUs and I need some clarifications.1. What is the difference between STM32U585RIT6 and STM32U585RIT6Q?2. On page 150 of DS13086, STM32U585xx datasheet, regarding power supply scheme, I can see the presence of VDDIO2 like below, But on LQFP64 pinout for STM32U585RIT6 doesn't have any VDDIO2 but three VDD pins.Does this mean some of the I/O pins are supplied with voltage from some of these VDD pins, instead of VDDIO2 cuz there is no such pin on LQFP64 package? Thanks, 

Currently i am using USB peripheral for communication (CDC) with STM32F070CBT6 microcontroller. For generating 48MHz clock, i am using internal oscillator as a source for internal PLL circuit. I have to send certain data to STM32 (for save it to external EEPROM (on same PCB card on which STM32 is installed). The STM32 will then acknowledge it. Similarly, STM32 will send the data to PC when requested. So, data transfer is only request based. Practically, I have tested it several times and it is working.But, now i have read the line from STM32F070CBT6 datasheet regarding USB as "It requires a precise 48 MHz clock which can be generated from the internal main PLL (theclock source must use an HSE crystal oscillator)."My Question is:- What consequences can occur if i continue with the internal source?

Hi there, we are trying to operate a STWBC86 on a rebuild of STDES-WBC86WTX.Eval boards are not yet available so we needed to build them with the given data on our own. when powering it up nothing happens so i assumed i need to program the supplied Firmware onto it via WPSTUDIO. When i try to connect to the board i get a Error message:   Wrong config ID and Patch Id for TX. I even cannot use the programming section of the tool as the buttons are greyed out: Documentation is very thin and doesnt`give information how to program the device on another way. How do i proceed ? can anybody help me on that issue? Best regards Stefan   P.S: Hi there, i was able to solve the issue by myself. You need to set the device to WBC86 and then Type to Empty to be able to program the device. afterwards everything works as intended.  

Hi, I am trying to use DMA in my project for SPI and noticed there are 2 type definitions as below:-  SPI_HandleTypeDef hspi1; DMA_HandleTypeDef hdma_spi1_tx;  Which one do I need to use for SPI transmission as I am having problems using 'hspi1' as below:-  HAL_SPI_Transmit_DMA(&hspi1, "Test",sizeof"Test"); HAL_SPI_Transmit_DMA(&hdma_spi1_tx, "Test",sizeof"Test");   I just wasn't sure which handle was the correct to use...

Hi, where can I get these two EVK? Since I searched these EVK model for 3 hours, and I can't find any.I searched all the sites including..(Mouser, Element14(Farnell) Digikey Avnet Arrow Newark OneChipStore, etc.)Can you help?

I use the ST25R/NTA5332 pair as an NFC Reader/Tag and ST25R391x firmware in my project.Why rfalNfcvPollerWriteMultipleBlocks method return the error? Is supported RFAL_NFCV_CMD_WRITE_MULTIPLE_BLOCKS command? I need to use rfalNfcvPollerWriteSingleBlock instead and it extremely slows down the exchange.

Hiwhen the STM32F103 enter the standby mode, it has the lowest power consumption. And it said the voltage regulator is switched off. And all of the data in the RAM will be lost except the backup ram and register of the RTC.But I tested it, the data will still keep the value (the standby mode could be entered successfully that the consumption will be reduced to several micro-amperes). the different thing is that all the supplies are still supply to the MCU (not only the VBAT).So that means the LDO is not actually switched off as it doesn't detect VDD to be lost or lower than the threshold.Is it right?

Wireless Power Requirements:-Require 5W on Receive side-Active Part Number and industrial temp rated-Air Gap: 20 to 30mm but ideally up to 40mm-Coil Size: 50mm or smaller is ideal, room to adjust size as needed-Don’t need to be compliant with any other standards but product will need to get FCC/CE certified, ideally don’t want to be able to charge anything else but priority is ease of design-Not very concerned about efficiency-Chip cost is a big consideration Questions:-Looking to run a device directly off power from the RX coil (no battery in device), are there any potential issues with this?-Transfer distance depends on many things including the coils used but how reasonable power transmission over this air gap distance? What are the many factors contributing to wireless power transmission distance?-Can I use a higher power transmitter such as 15W to get longer distance even if I only need 5W?-Is the STWBC86 the best choice for this application or can you suggest other options?&

Hı everyone, ı was trying to design basic timer project in register level about toggling on related led pin every 1 second. However, the led is on a few seconds after that it is off and never becoming on. When ı do the same project in HAL library, it worked well. By the way, I use APB1 as 84 MHz. Is there anything i missed out ?  /* Includes */ #include "stm32f4xx.h" #include "stm32f4_discovery.h" void RCC_Config() { RCC->CR |= 0x00030000; // HSEON and HSEONRDY enable while(!(RCC->CR & 0x00020000)); // HSEON Ready Flag wait RCC->CR |= 0x00080000; // CSS Enable RCC->CR |= 0x01000000; // PLL ON RCC->PLLCFGR |= 0x00400000; // PLL e HSE seçtik RCC->PLLCFGR |= 0x00000004; // PLL M = 4 RCC->PLLCFGR |= 0x00005A00; // Pll N = 168 RCC->PLLCFGR |= 0x00000000; // PLL p = 2 RCC->CFGR |= 0x00000000; // AHB Prescaler = 1 RCC->CFGR |= 0x00080000; // APB2 Prescaler =

Hi,I am working on a new product. For this I use the STM32H723 µC and the LAN8742Ai PHY from Microchip.Our schematics looks like this:We have a 25 MHz crystal connected to the STM32H723 (HSE). The MCO is configured to HSE. The crystal matches the clock requirements of the LAN8742Ai. The LAN8742Ai has a PLL that generates 50 MHz. This frequency is used as the reference clock for RMII communication.Now I have the following problem. When we run the product in a climatic chamber, sometimes the RMII communication does not work. The TCP/IP connection is broken, because messages sent from the STM32H723 to the PHY are not recognized by the PHY.So my question is, waht is the frequency for MCO? Is this constelation generally allowed? Where can I make improvements. We used this PHY because it is the same one used on the NUCLEO-H723.The PHY can be used for industrial applications down to -40 °C. It is not the PHY for consumer applications Best regards,sada1400
