STM32 MCUs Products

How, recover from and prevent wrong (?) definition of BOOT0/SWCLK after first firmware download.

Hi, I am using the STM32G071KBU6N. It has the BOOT0 and SWCLK (PA14) on the same pin. Defined the pin as SWCLK in STM32CubeMX. So I assume that the SYS registers are set right in the software generation. However after the first download of the first ...

STM32H7 STM32F4 spi

Hello, I am trying to use an ADC (AD7124) which is communicating through SPI with the MCU.Previously, I managed to run the ADC with STM32F4. For this I used the libraries provided by the ADC manufacturer. While the ADC is running prefectly with STM32...

Clock multiplexer of USART2 in STM32F051R8?

Dear all,The MCU : STM32F051R8T on Discovery BoardIssue : USART1 and USART2 are required. The clock of USART1 can be configured by CubeMX. However, it is not possible for that of USART2DetailsThe clock source of USART1 ...

STM32F030 SPI Problem

Hi, I'm using stm32f030cct6 and control the sx1276.​I configured SPI1 like that​void SPI1_Init(void){ SPI_InitTypeDef SPI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure;​ RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA | RCC_AHBPeriph_GPIOB, ENABLE); R...

HSERDY flag doesn't set - NUCLEO-STM32L4R5ZI

Hello,I am trying to config my board using HSE as SYSCLK (my board has MCO from ST-LINK as external clock supply by default - 8MHZ)The goal is set SYSCLK = 8Mhz, HCLK =4Mhz , PCLK1/2 = 2MhzProblem: HSERDY was never set within the TIME OUTPlease lets ...

Why does the DMA gets out of sync when doing a sequence of regular AD conversions on stm32f103C8TX? This only happens with DMA_NORMAL.

It works with DMA_CIRCULAR (but I do not want or need continuous DMA transfers.)You see by the terminal output below that reading 2 analog inputs works OK. However, after a while (< 1 minute) the 2 analog values are exchanged now. Apparently the DMA ...

I plan to use UART1 and CAN on STM32F103C6 (48pins). Do I need to remap CAN having USART1 configured in asynchronous mode (CTS RTS disabled)? Can UART1 and CAN work on its default pins simultaneously.

Hi, I want to implement canopen protocol on a stm32H7, How can I do this with HAL drive? thank you.

WDT

Hello,I am working with STM32F4 family.I want to add WDT mechanism to my application as a "safety belt"I already have devices released for customers, so my question is :Is it safe to add the WDT mechanism to my application but not to the bootloader? ...
