Solved

I have a circuit with stm32l010f4 that has no ADC pin available because I am using them as digital GPIO, but I need to measure the battery voltage in my application, my question is if Vrefint can be used to make the measurement. I have already made the configuration of Vrefint in stm32cubeide but it only gives me a value of 1.

Hi all,I am working on a university project to build a small IOT camera. I am using the 32F746GDISCOVERY board with the STM32F746NG MCU along with the ov2460 image sensor from WaveShare, and the B-CAMS-OMV board as an adaptor.My code is based on an example for the STMF7508 Disco board, however, I have switched out the ov9655 BSP used in the example for the ov2460 BSP provided by STM.Initially, I am attempting to display a continuous video feed on the LCD screen using the following data path:Image Sensor → DCMI → DMA2 → Camera Frame buffer → DMA2 → LCD Frame bufferI am able to communicate with the image sensor through I2C and successfully read the ID. When the image sensor is initialised, I am receiving frame event callbacks, however, no data is being written to the camera frame buffer. The DMA transfer between the camera frame buffer and the LCD frame buffer seems to be working fine.I am pretty stumped as to why no data is being written to the camera Frame buffer and I have been workin

I have to configure it as a Client. Can please someone help me with the starting guide for the client configuration like how to establish connection with server and how to write attribute to server, everywhere I found only starting guide for server only.Thank You,Arief

Hello, I can't get a current lower than 108µA in stop1 mode. It's expected 3µA in the datasheet.I set all pin in analog input mode, disable the debug in low power mode.I try with the NUCLEO Board as explain in the article number n°2190.I also removed all JP2 jumpers to decrease the current consumption of the shift level.Has anyone always succed to get 3µA in stop1 mode with this MCU.Thanks,

I would like to ask if someone has a code for the implementation of the RFAL and NDEF libs for X-NUCLEO-NFC05A1 NFC Card Reader? Hope you can send me the sample code because it is really hard to port the Middleware to Mbed Studio.

AN4718 "How to design a V BAT system based onSTM32L0/L1 ..."Case 1b, it is stated, quote:"V DD /V DDA can also be switched to V BACKUP when STM32L0/STM32L1 MCU goes into STOP mode, to allow user to remove main supply in very safe way."End quote.Question: What does that mean "very safe" ?What is the exact purpose of that PMOS switch ?Is is to prevent the supercap current going to a battery pin ?What is unsafe if not used ?

Hello, I want to compare text area content with enum TEXTS. How can I do this?

Hi,I wanted to know how can we change the values of prescaler and counter period for a timer in STM32 using the code and not the UI. Please help.

Hello,After prototyping with a Nucleo H7 board, I'm setting now up a custom board with a STM32H723ZGT6 MCU (the same MCU present on the Nucleo).I connected my USB Dongle ST-Link V2 via SWD to program the MCU and after having struggled a bit, I have finally come to a working setup but with quite slow frequency 100 Khz as solution. Increasing the frequency leads to impossibility to erase, to download my program or sometime to generate inconsistency errors between what is downloaded and the original code.At 100Khz debugging is a bit of a challenge so i need to speed it up if possible.Anyway what is stressing me is that I don't understand if that's normal or not...In terms of the SWD my setup is: SWDCLK and SWDIO connected directly to the dongle, RST connected with a 10k resistor between the dongle and the MCU, gnd and VDD connected to 3.3V on the board.The St-Link V2 dongle framework is updated to last version.Config of SWD is:1) frequency 1002) mode Normal3) Access point 04) Reset mode H

TouchGFX 4.21I have defined a user container: "Selection".The container contains two buttons: switchToScreenOne and switchToScreenTwo.I have also defined an interaction for each button that changes the screen. I have defined two screens: One, Two.Both screens contain the container "Selection1"The process works fine. Question: How can I set the color of the buttons in the containers in the ScreenOneView::setupScreen() function?I have already tried everything and just can't find the solution.

I'm using a nucleo f401re with a lps25hb. Currently I'm getting very wrong values, this is caused by the reading of the registers. For example when I call the registers of temperature which is composed by two bytes HAL_I2C_Mem_Read(&hi2c1, LPS25HB_I2C_ADD_H, LPS25HB_TEMP_OUT_L,         I2C_MEMADD_SIZE_8BIT, bufp, 2, 1000);It only reads the LPS25HB_TEMP_OUT_L to the bufp p array. If I call the two registers LPS25HB_TEMP_OUT_L and LPS25HB_TEMP_OUT_H separately, it works fine. Therefore I doubt I missed something in the auto-incremental register address setting of the sensor.Thx in advance.

Hi,I am using STM32H745BIT6 controller and wish to use the external flash memory as a mass storage device. The external flash memory is connected on QSPI.The application would be, user will connect the USB cable to PC and PC should be able to show the external QSPI flash as a drive on PC i.e. as a mass storage device. Is this possible with STM32H745BIT6 device?. Please point me to some examples which can be refered.ThanksAnuj.

Hi there,I am having trouble with CubeIDE: When building my project i get the following error:"fatal error: core_cm4.h: No such file or directory"I am using:MCSDK 5.Y.1STM32CubeMXSTM32CubeIDE 1.6.1STM32F302R8 NucleoBoardX-NUCLEO-IHM07M1 motor driverSPI-Sensortwo external buttonsWhat I did to get to this point:Generated the project via MotorControl Workbench and CubeMX --> project is for a Motor Control applicationModified the project with CubeMX: added few GPIO Inputs and Outputs, added a Timer (TIM16) and SPI2Added the Project to the CubeIDE workspaceadded some own Codehit buildgot the error: "fatal error: core_cm4.h: No such file or directory"tried to add the include path manually --> did not workHope someone can help me on thisGreetings MM1

My code is simply :HAL_Delay(100); HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_5);   uint8_t buffer[] = "Hello, World!\r\n"; CDC_Transmit_FS(buffer, sizeof(buffer));But nothing...> The led is blinking.> The VCp is define via *.IOC with no error.> Compilation without error.I see a VCP but i think is the st-link debugger VCP.It's right ?Do you have advice for me ?

I just migrated to the latest v1.11 of STM32CubeIDE.I was able to update successfully to the latest version, but now my environment is broken!Issues I see now: Build an stack analyzer gives the following output:Could not create the view: com.st.stm32cube.ide.mcu.stackanalyzer.stackanalyzer.viewUnable to open the dedicated .ioc file:Gives an NullPointerExceptionAlso I'm unable to restore my environment downloading the latest installer file. The website is having issues and I'm unable to login / download content disappears after login. Please ST help me with an urgent workaround!EDIT: Website back online, "solved" by using the installer of v1.11. Please fix this ST!Regards,

why you have enabled crc for mp3 player in your examples ?What is its purpose?uint32_t Mp3Process_DecoderInit(uint8_t* pHeader, fnReadCallback_TypeDef* pReadCallback, fnSetPositionCallback_TypeDef* pSetPosCallback) { __IO uint16_t time_out = 1153; uint8_t tmpBuffer[10]; uint8_t nb_frame = 0;   uint32_t i;   /* Enable the CRC */ #ifdef STM32F10X_CL RCC_AHBPeriphClockCmd( RCC_AHBPeriph_CRC, ENABLE); #else RCC->AHB1ENR |= RCC_AHB1ENR_CRCEN; #endif /* STM32F10X_CL */

I'm very new to the STM32 and am trying to set up TIM2 to trigger a dma input capture to memory. I have been pouring over examples and the STM32F302R8 ref manual but am not there yet.What is working is I am inputting 30Hz ref signal on both PA5 and PB10 (TIM2_Ch1 & TIM2_Ch3). These are being detected and I see the CCR1 and CCR3 registers reflecting the capture count.What is not working is I don't seem to be generating (or servicing) a DMA request. In my code I am using HAL_DMA_Start and __HAL_TIM_ENABLE_DMA for both DMA channels 1 & 3 on the TIM2. The respective memory buffers are buffer1 and buffer2 in SRAM. I initialize these to 0xdead at reset and see them get updated once after the DMA is enabled and the TIM2 capture/compare is enabled, but after that the buffer never gets updated again.Also in the TIM2 SR register the CC10F and CC13F overflow flags are set, and my two DMA IRQ routines never get triggered.Am I missing a critical enable somewhere?I've seen in some discussion

I observed the data on both MOSI and MISO on logic analyzer, even when I use only one of the HAL_SPI_Transmit() or HAL_SPI_Receive(), why?

Hi, there!Please help me !!!​I am testing Timer cascading with F411 Back pill on STM32CubeIDE.​TIM2 [Master] ---> TIM5 (or TIM9) [Slave]​There is no description on Periphral Interconnect Matrix feature in the STM32F4 manual (RM390), but I found the same in that of G4 (RM0440).According to the manual, TIM2 sends its TRGO to ITR1 channel.However, in my case, it does not work with ITR1 and I need to use ITR0 instead of ITR1.More over, if I use ITR1 (in TIM5), TIM2 [Master] does not work.(Using ITR2 and ITR3 will not affect to TIM2, but TIM5 does not get clock from TIM2.)Please help,1) Does anyone know the Periphral Interconnect Matrix feature for STM32F4? Where can I get the Info.?2) Can some of you check if the phenomenon above is common to other MCU or not? (Please see the working code below.)Thank you very much for your kind help in advance.

I am attempting to get the display example running on a nucleo board. I am following this document:um2787-getting-started-with-the-xcubedisplay-stm32cube-expansion-package-stmicroelectronics.pdfI am getting the following issues and I don't know how to resolve them:I tried to click the resolve button but it resulted in more yellow triagles and this when I closed the component selector.The document doesn't describe what to do if it doesn't go as planned. It also describes the setup for a different Eval board. However it states both in the start of the document and on the webpage for the display expansion that this should work for the nucleo board. I'm fairly new to STs tools so I have no idea how to resolve these. Any help is greatly appreciated.
