Hi,I'm trying to do 3-WIRE SPI communication with DAC60501,but no matter what I do, the output value doesn't change.I checked the waveform with a scope and it all was OK.The first falling edge of SYNC starts the operation cycle --> CPHA= 1 Edge 

"C5" typo corrected in title to "C0"Does have the STM32C5 and STM32U5 microcontroller documents e.g hardware user manual?Could you please help me to confirm this?

Hi,  I don't understand why CubeMX is limiting me through their IOC file to select an ADC clock below 2MHz. The datasheet says 140 kHz is the minimum ADC clock frequency for the STM32G07. Anyone has any answers or help ?. 

Hello,I had two related questions to clarify - 1. Can multiple Op-Amps be used in the differential mode simultaneously and their output fed to ADC for measuring input DC voltage?2. Also, since the Op-Amps inside the STM32G4 MCU are not rail-to-rail, they only output 0-3.3V for the given input. I am only interested in measuring DC input. Connecting the Op-Amp GND to system ground (0V) would give me the full range of output for DC (NOT 1.65-3.3V, but 0-3.3V), right? Thanks.

    I want to try the VL53L7CH, I purchased the SATEL-VL53L7 and the x-nucleo-53l7A1. When I look at the boards on the SATEL-VL53L7 they look identical. But the description says it supports both the CX and CH models. Can someone clear this up?

Hello!I am attempting to charge a 3.7 V Li-ion battery using the SPV1050 on the STEVAL-ISV019V1 evaluation board, but there is a current coming from the battery into VBATT which ranges from 400 uA to 1 mA.The current remains even when no load is connected, and when a solar cell is connected to PV+. Additionally, the current remains when the battery is replaced with a 4 V voltage source in series with a 1 kOhm resistor.After reviewing the datasheet of the SPV1050 and the evaluation board, no components draw anywhere near this current so I suspect that my chip is damaged. However, the control logic and MPPT mechanism works perfectly fine so I am confused.I'd be very grateful if anyone could help!

Hi,I,m looking for a way to remove or hide the keychar of the keyboard's keys or button, i'm using the custom keyboard from TouchGFX demo or examples, and i have a new asset that already have the keychar or key label. For this reason, i need to remove the keychar and prevent the keyboard class from drawing them.How i can do that?Best regards.

Hi Expert, Good day. Refer to the attached label image. One label shows MSL 1 and the other shows MSL 3 for MPN LIS2DW12TR. However, the Reliability Evaluation Report for this P/N indicates MSL 1. Both labels have the same COO but different MSL levels. Is it possible or Is there any PCN behind this change? [images deleted by a moderator] Looking for your support on this.   Thank you.

I'm configuring an STM32G031, using the STM32CubeMX perspective in STM32CubeIDE.  I want to optimise for low power consumption.  My device uses the ADC and I see the ADC has a minimum acceptable frequency, 140kHz according to the data sheet (data sheet table 57, fADC must be at least 0.14MHz).I've configured the clock so that SYSCLK = 2MHz (HSI 16 MHz oscillator, divided by 8).  The ADC clock is also shown as 2MHz.  That makes sense.But in the ADC configuration panel, the only clock options I can select are "sync divided by 1" or "async divided by 1".  I expected to be able to select higher dividers, down to "async / 8" (which would be 250kHz).  I can't even select "sync/async divided by 2" (which would be 1MHz).  All those slower options are greyed out, and when I mouse over them there's a tooltip that says something like "prescaler does not respect fADC fmin fmax conditions" or something like that.Is this a configuration

Hi all,Board: STM32H745I-DISCOIDE: 1.16.1 I am facing some issues with trying to execute code on the SDRAM. I have a 2nd stage bootloader that loads the user application onto QSPI located at 0x9000 0000. After that, I copy the user application code to the SDRAM 0xD0000000. This part works as verified in the debugger. However when I try to jump to the SDRAM address, my program is not executing. And it seems like the SDRAM has lost connection? Attached below is the image(sdram_becomes_unreadable.PNG) where my bootloader jumped to the SDRAM address but unable to read from the SDRAM. There is no hard fault.. Background: I have tried to load the user application onto QSPI and jump to the QSPI address, my program executes successfully. I have checked my MPU configuration to make sure that SDRAM is MPU_INSTRUCTION_ACCESS_ENABLE. Below is my MPU configuration&n

Hi, I am reaching out to kindly request NUCLEO-C051C8 project files ( It seems that ST uses Altium).Altium files would greatly facilitate my development.Please help me.

Hi,I am using LPUART and LPDMA on STM32U575. But I am getting Data Transfer Error.I have tried LPUART with GPDMA it works fine but LPUART with LPDMA giving Data Transfer Error.So I have two questions:1. Can we use LPUART & LPDMA together?2. What will be the cause of Data transfer error and how to configure LPDMA ?Can you please guide me on this?

I was going through the reference manual of STM32G4 series MCU. I saw information on using Op-Amps inside the STM32G4 as Inverting and Non-inverting amplifiers. There was no mention of them used as differential amplifiers, can they be used as differential amplifiers?

According to the UM2829 manual stating that it supports "SLAVE_I2C STREAMING on I²C pulses", I would like to ask whether this means that image data can be obtained via I2C like the VD55G1, or if it only refers to synchronization signals between image data, with image transmission being possible only through MIPI CSI. Additionally, is there any code for obtaining images via I2C, such as starting to read from which address?

Heyho,how can I put a constant at the end of the STM32's used flash? (using: STM32CubeIDE)Not at a specific address (that's not a problem), but I'd like to have a constant always at the end of the used internal flash, independent of any other source code changes.I just find that there's some ASCII characters = "ASCII" (twice) and lots of 0x00 at the end of my H7 and F7 bin files - that from my sources or placed by CubeIDE? Thanks!

Hi, I have problem config LTDC for 1280x720 @60Hz. Without caching it works no problem, but slow. We are using 32MB SDRAM 16bit, config at 100MHz. When we use MPU to cache SDRAM, code as below: ``` MPU_Region_InitTypeDef MPU_InitStruct; /* Disable the MPU */ HAL_MPU_Disable(); // Region 0: All 32MB cached MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.BaseAddress = 0x60000000; MPU_InitStruct.Size = MPU_REGION_SIZE_32MB; MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS; MPU_InitStruct.IsBufferable = MPU_ACCESS_NOT_BUFFERABLE; MPU_InitStruct.IsCacheable = MPU_ACCESS_CACHEABLE; MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER0; MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0; MPU_InitStruct.SubRegionDisable = 0x00; MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE; HAL_MPU_ConfigRegion(&MPU_InitStruct); // Region 1: Last 4MB as non-cacheable f

Hi we are looking for optical flow sensor and try to configure VD56G3 camera for this purpose which is connected to rasberry pi 4.I came across research artice which states that it does support optical flow using  MIPI CSI-2 interface.https://arxiv.org/pdf/2305.13087 However just looking at the

function HAL_InitTick() in generated code from STM32Cube IDE does not register the TimeBase_TIM_PeriodElapsedCallback after HAL_TIM_Base_Start(&htim6). it just returns the result if Timer Start.setting up the callback is done after this but never reached when HAL_TIM_Base_Start() worked fine. As a result, the tick does not count. if(HAL_TIM_Base_Init(&htim6) == HAL_OK) { /* Start the TIM time Base generation in interrupt mode */ return HAL_TIM_Base_Start_IT(&htim6); } HAL_TIM_RegisterCallback(&htim6, HAL_TIM_PERIOD_ELAPSED_CB_ID, TimeBase_TIM_PeriodElapsedCallback); /* Return function status */ return HAL_ERROR; }Edited to apply source code formatting - please see How to insert source code for future reference.

Is there any publicly available info on how the profiler works?

I'm a USB newbie and am trying to use the STM32F411CEU6 as a USB mic. I'm currently using FreeRTOS (cmsisV1) and the Cubemax USB library. My device currently enumerates normally, but when the host sends a URB_ISOCHRONOUS_IN request, my MCU won't handle it properly (according to SWD and serial port debugging, I found that the MCU won't even enter the OTG_FS_IRQHandler interrupt when the host sends this request). This has been bothering me for a long time. Here are my descriptors and some configuration code:__ALIGN_BEGIN static uint8_t USBD_AUDIO_CfgDesc[] __ALIGN_END = { /* Configuration Descriptor Head */ 0x09, // bLength 0x02, // bDescriptorType = CONFIGURATION 0x6D, 0x00, // wTotalLength = 109 bytes 0x02, // bNumInterfaces = 2 (Audio Control + Audio Streaming) 0x01, // bConfigurationValue 0x00, // iConfiguration 0x80, // bmAttributes: Bus powered 0x32, // bMaxPower: 100mA /* -------- Audio Control Interface (Interface 0)

Hi community, I'm having struggles with EXTI in WBA55CG. I want to implement a function, when the button is clicked, a message is sent via BLE. I have found the stm32wbaxx_hal_exti.c file. Can I follow exactly the same as the instructions or what i add more? Thank you.
