I'm using STM32H753XI Eval 2 board with MT25QL01GBBB external flash on QSPI interface.I've configured it in 4 byte addressing mode but I'm not able to read the data correctly.I've referred code from here,https://github.com/STMicroelectronics/STM32CubeF7/blob/master/Projects/STM32F7308-DISCO/Examples/QSPI/QSPI_ReadWrite/Src/main.cQSPI Init:uint8_t QUADSPI_Init(void) {   hqspi.Instance = QUADSPI; hqspi.Init.ClockPrescaler = 1; hqspi.Init.FifoThreshold = 4; hqspi.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_HALFCYCLE; hqspi.Init.FlashSize = 31;//25; hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_1_CYCLE;//QSPI_CS_HIGH_TIME_1_CYCLE; hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0; hqspi.Init.FlashID = QSPI_FLASH_ID_1; hqspi.Init.DualFlash = QSPI_DUALFLASH_DISABLE; if (HAL_QSPI_Init(&hqspi) != HAL_OK) { Error_Handler(); } /* QSPI memory reset */ if (QSPI_ResetMemory(&hqspi) != QSPI_OK) { return QSPI_NOT_SUPPORTED; }   /* Put QSPI memory in QPI mode */ if

Hello.I don't see ISM330DLCTR in stock anywhere? Is there any alternate part. I can see LSM6DSM. Will it work with same software. Any suggestions?Thanks,Kumar

HI,All , if any one have done HSE enabling in Stm32f072 & Stm32f103 MCU please share.As what ever examples available are for HSI clock only .So please some one revert .WaitingRohit

I want to know what is use of user data in option bytes programming?it helps to protect my firmware inside MCU like password or etc?

Hi，I use ADC1_INP2 for single-end mode , how the ADC1_INN2 connect to？Internal VREF- or outside GND？ And in differential mode，ADC1_INP6/ADC1_INN2 use de same pin, is that i can only use ADC1 channel 2 in differential mode? ADC1 channel 6 can't be used.

I understand correctly that in stm32h743 you can delete only a sector of 128K bytes minimally?

Is there documentation for a composite list of driver API for the STM32G071 MCU? The examples are good, the STMCubeMX pin generator also helps. The driver files are there. But there are so many APIs for timers, interrupt callbacks, UART etc. Are there resources other than online searches to help use HAL, LL APIs?Thanks,Priya

Hello,I put my STM32H743XI in Bootloader mode and launch STM32Cube Programmer USB example on VS and got : I have two question :Where does this error comes from and how to fix it ?Can I skip option bytes programming and still flash my MCU ?Regards

Hello I am using the STM32F334 for Lighting and I have had to use the DMA to transfer duty cycle data to the PWM duty register. The DMA is set up in circular mode and there is no interrupt. The priority it set to High. But i notice this pauses between the packets. I would have expected it to have no pauses. Please how can I get rid of this? Please see the image of actual light intensity. Hope to hear from you. thanks

Hi, I connected the BFA01V1B and running condition monitoring code. My settings are Accelerometer parameters are:   HpfCut =3   Acc_Odr=6660   FifoOdr=6660   Acc_Fs =16   MotionSP parameters:   size=2048   tau=50   wind=1   tdtype=0   tacq=5000   MotionSP Vibration InitializationMotionSP Parameters are:   FFT size: 2048   FFT ovl : 75%   Tacq   : 5000 msUpdate Accelerometer Settings:   Ok Enable HP Filter   Ok FullScale Setting   Ok Set Output Data Rate   Ok measure and calculate ODR   ODR = 6582.00 Hz   OK Set Accelerometer Parameters   Ok Bypass FIFOThe Results are:    ************************************************************* &nbsp

I want to use an accelerometer to calculate the speed of a moving vehicle. For this i need a accelerometer which should give _ve values(2's complement) in Deceleration and +ve values in (2's complement) in acceleration. It should have 2g range with 12bit(or more) resolution. with less noise affected. It should have less Zero offset error.If there is any sensor Please Suggest me one.Thank you in Advance.

Hi everyone,I do have 2 PCB boards based on STM32F030F4P6 MCU, the two PCBs have the same hardware and connection with other components, I read the first MCU's code using ST-LInk V2 -using SWD- and saved the .hex file to my PC then I wanted to re-program the other one with the same code, the programming proccess works well and the ST Link utility says that it success but when trying to run the code it says "unable to run" what shall I do to correctly copy the same code? I program the flash memory and make sure that the Option Bytes are the same, what else must be copied to let the MCU work?Thanks in advance.

Hi there.I am new to this, so do not judge me. Here is the question:Which GPIO pins from STM32F415R (so the one with 64pins) I could use for lighting up a led?Here is the documentation for it: https://www.st.com/resource/en/datasheet/stm32f415rg.pdfThank you!

Hi guys,I'm designing a custom board with STM32MP157C using the MB1263 board as reference.The MB1263 reference design shows the VDD_OTP pin tied to VDD, which is 3V3 for that particular board. My custom board uses VDD = 1V8 instead of 3V3. Should I tie the VDD_OTP to 3V3 or 1V8? I could not find any reference on VDD_OTP recommended voltage.Thank you in advance.

Helloi'm using stm32f103rct.Use cubemx and just set RCC,and SYS(JTAG, Timebase Systick) compile with IAR and then download and debug press break.Hard fault exceptionhelp plz

If i use IAR's Download and dubug, the program works normally.However, if i do H/W reset or Power off/on, it will not operate normally.what should i check? MCU : STM32F205ZETIAR 8.40.2Own boardST-LINK V2

Hi Team,I have installed ST Visual Develop in ST web page. At the end of installation, installation page got stuck and then i have terminated by end task using task bar....After completion of installation, i have opened software then following error message has occurred as shown in figure "while_opening". and exit from IDE as shown as "while closing".In IDE --> help ---> Generate support file... pl find the file support file.....Please guide me to solve this issue soon....Thanks & Regards,Anand Kumar.

Hello! We have been told that the STM32F030C8 is going to be discontinued. We have several product lines using this MCU. On the ST website this MCU is listed under the 10-year longevity commitment. How do we enroll in this commitment? What does this mean? Would you allows us to do a lifetime buy of these MCUs? Is there a direct replacement for this part that you recommend that would have the least impact on FW development? Thank you!

Hi.I am using MCU STM32F070CBT6TR on my custom board, I do use ST-LINK/V2 as hardware tool, and I have configured the boot options according to this: But in fact the MCU is not running the code, it keeps in lockup state, and then I am not able to debug the code on Utility nor in the IDE, because the MCU doesn't even run. Pin 44 (BOOT0) is connected directly to GND.Pin 7 (NRST) have a pull-up of 4.7K and is measuring 3.3VWhat I am doing wrong?

I am currently using the Nucleo G071 RB eval board. The application will transfer data to the USB port at the end of processing. I am using UCPD1 on PA10, PA9, PA8 and PB15.Do I use the STM32CubeMonitorUCPD to view this data? I am assuming I will need to jumper these UCPD1 pins to a USB cable that connects to my laptop. Is RTOS needed to use UCPD1 for this purpose?Thanks,Priya

I have been getting into issues on the STM32WB Nucleo Eval Board. As of now, i've been working on the BLE_Custom example from the Firmware 1.9.0. and i have it to where it bonds and has no MITM protection on. Once running it from the CubeMX and opening on the IDE any slight changes like making a command within the Main.c and in the while(1) loop it seems to not be found on any of my devices. Just opening the example with the configurations changes and not changing anything on the IDE makes it appear and paired up with my ios device or my laptop. I don't know if its a fault on the IDE, example or MX program. I also had tried changing the GAP name with the same character length and as well it did the same error where its not recognized by any of my devices

HiIm using samsung galaxy j5 accelerometer for a research work about automobile acceleration and deceleration. As you know samsung electronics uses stm mems sensors on its smartphones. In case of galaxy j5, based on some papers, the accelerometer name is K2HH! Some applictions show the same name too. I didn't find any datasheet about this sensor on the site.I appreciate any help about the sensor, it's real name or any other data.Best regards.
