STM32 MCUs Products

Hi all, I am trying to get the USART1 working with STM32F072VB micro (only USART-1 and no other peripheral). At CubeMX, I have seleted PA9 and PA10 as the GPIO pins configured for USART-1 and have selected the NVIC option at USART configuration at CubeMX.

huart1.Instance = USART1; huart1.Init.BaudRate = 9600; huart1.Init.WordLength = UART_WORDLENGTH_8B; huart1.Init.StopBits = UART_STOPBITS_1; huart1.Init.Parity = UART_PARITY_NONE; huart1.Init.Mode = UART_MODE_TX_RX; huart1.Init.HwFlowCtl =...

Hi guys, I hope everyone is fine. I am working on bootloader. For this i use ST's X-CUBE-IAP-USART software and trying to use this software for adapt my MCU. I am having trouble with clock settings while doing this.I wonder if anyone has been dealing?

How should filter and mask ids be in stm32f446re processor? How can be filter id and mask id in EXID? I am new here. I am waiting your help. Thanks.

Cannot Re-Enable EXTI After Disabling It

I want to write an application in which whenever an external interrupt occurs on a GPIO pin, the EXTI gets disabled until a certain amount of time is passed, and then it gets enabled again.What I tried is that I have put the following lines in the HA...

STM32L0x2: How to use PH0 for external clock and PH1 as GPIO?

Hi, I’m working on a board with an STM32L072RZ. I have and external clock source connected to PH0. And I want to use PH1 as GPIO. According to the Reference Manual RM0376 at section 9.3.13 this should be possible. But in section 7.2.1, the document a...

Data bits shifted in SPI communication on STM32L462 after repeating one successful session (consisting of NSS falling edge, 3 separated transmissions with HAL_SPI_TransmitReceive, NSS, rising edge)

Data bits are shifted on second SPI session (BSY bit stay high at the end of data transfer in slave mode) We are using STM32L462VET6, and initialize SPI2 in full duplex slave mode (CPOL=1, CPHA=2-edges) with software NSS and baudrate 960 kHz with HCL...
