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? ...

There are fast and slow channels for the ADC of STM32H750. It's only a hint in the reference that analog switching is different speed for GPIO mux and ADC input mux. If there more exact information on the speed of slow channels?

STMicroElectronics Virtual com port driver behaviour on Windows 10

What happens if STMicroelectronics virtual com port driver version 1.0 and 1.3.1 is sitting on windows 10 computer? How will it behave? As inbuilt / inbox / out of the box windows driver is sufficient for Windows 10, what version of the driver will ...
