STM32 MCUs Embedded software

HAL_UART_Receive_DMA(&huart1,... and HAL_UART_Receive_DMA(&huart2,.... Usually work well but not if I use in the same program TIM2 with the following instruction HAL_TIM_Base_Start_IT(&htim2).... The timer TIM2 keep working.

STM32F769i-disco - is there a way to tell if the board is connected to USB like by using vbus or another facility?

I'm really trying to tell if the board is connected to an external comm port to turn off usart sends so they don't potentially backup and slow things down. I know other products expose thinks like vbus sensing? Don't know much about it. I tried to...

When is the IDLE line detection interrupt triggered for UART?

Hello,I'm trying to use the async Zephyr UART stm32 api, but I've encountered an issue. I'm using STM32F412.I'm trying to use the Zephyr UART stm32 async API(with DMA), with 3Mbps. I can see that the received data are correct so the baudrate/frame/DM...

ORE flag of USART_ISR is not being cleared by HAL layer in STM32-Nucleo-H7A3Zi dev-kit.

Hi community. Greetings of the day!I'm using ThreadX RTOS thread to receive the data from USART and I'm sending it to the ThreadX queue & transmitting it to the USART(Tera-term display).What happening is that I'm using IT(interrupt) method to receive...

STM32Cube - UART Polling Parity/Overrun Errors Checks Missing

Hello,We are using UART polling and had it configured using STM32Cube. That was great until we realised there wasn’t any built-in checks for parity errors, overrun errors, …. How come those errors seems to be checked within the handler when using non...
