STM32 MCUs Products

We are using STM32l412 microcontroller in one of our project but every time if we need to flash the firmware we need to power the target board USB is not powering the controller while programming

How to send 32 bit data on HAL_SPI_Transmit

I want to send uint32_t spiData1 = 0x48240000; using HAL_SPI_Transmit func but I'm unable to send this data.How can I do the following thing.

HSI48 and CRS accuracy issue

Hi all, I am using the STM32H755 Nucleo board to test a proof of concept clock recovery solution. I am using the CRS external GPIO sync pin with a 1kHz refclk to synchronise the HSI48, and output the synchronised clock on MCO1. The issue I am having...

STM32H750 with Dual-Flash , can not work after enable the TimeOutActivation in memorymapped mode.

If i enable the TimeOutActivation in the memorymappedmode then device hangup randomly. if i disable the TimeOutActivation then it work normally.The code snippet as below :QSPI_EnableMemoryMappedMode(QSPI_HandleTypeDef *hqspi)  s_command.InstructionMo...

STM32G031J6 stuck in non programmable mode

Hi there, during the development I have accidently flashed (via ST-LINKv2 SWD) two chips (stm32g031j6) with program which sets PA13 as INPUT, PC14 PWM OUTPUT and initiated hardware SPI (pins PA12, PA11, PA1). After flashing this program, chip does no...

SRAM reserved location usage

Hi, I am using STM32F779NI and Keil IDE. I have defined SRAM start area in Target options from0x20000000 with size as 0x80000. Now, I want to write a keyword at known location in the memory. The memory area should be selected such that incremental de...

Unstable ADC readings with STM32F030

Hello all I have a problem with unstable ADC readings with my STM32F030I use CubeMX to set up my device.My ADC init :static void MX_ADC_Init(void) {   /* USER CODE BEGIN ADC_Init 0 */   /* USER CODE END ADC_Init 0 */   ADC_ChannelConfTypeDef sC...

Hi everybody, I'm currently trying to write a program on a STM32F303RE that measures an analog signal. I tryed to use the code from @[John Craven]​ but it didn't work. Can anybody help me?

In this post: https://community.st.com/s/question/0D50X00009XkYXZSA3/adc-with-dma-triggered-by-adc-watchdog-signal-peak-recordingJohn Graven posted his Code which I took and changed it a bit for my purpose. Unfortunately my Buffer adc_buf and my vari...

STM32L0 Eval board: DMA with 4 ADC channels not able to capture samples in sequencer mode

This is with reference to get your input regarding ADC channel reading in STM32L0 Evaluation board.I am using 4 ADC channels being configured under DMA for one of our flagship program which is running very critical by considering high business volume...
