HAL UART Overrun causes it to never receive data again in normal and interrupt modes

HAL_UART_Receive and HAL_UART_Receive_IT contain a bug. To reproduce (I use STM32L412KB nucleo 32 for this):Connect a terminal emulator to the ST-LINK as serial port.Configure that serial port in CubeIDE if default not chosen.Use for example the foll...

Resolved! TouchGFX: UART to UI WITHOUT RTOS!!!

I am trying to display UART data received to UI WITHOUT RTOS but I am unsure how to code the model, I am getting error every time. I read the documentation and tried to reproduce the same thing but in vain. I watched a lot of videos on youtube but th...

Using a defined constant inside HAL_UART_Transmit

stm32l4xx_hal_uart.c: UART_WaitOnFlagUntilTimeout() does not clear ORE

I am using STM32CubeIDE 1.7.0 with a NUCLEO-L432KC (STM32L432K). I wanted to add support for stdio via the VCP UART and successfully implemented __io_putchar(). However, I struggle(d) to get __io_getchar() to work by using HAL_UART_Receive() (because...

STM32CubeIDE & C++ - Redirected printf no longer works - How to use cout?

Hi,I have a "C" project where the printf detailed below works for outputting to a UART.When I change the STM32IDE compiler to a C++ project, the printf no longer works./**************************************************** * UART Redirect ...

Does STM32G070RBT6 MCU support USART(RS-232) software (XON/XOFF) flow control by default? If not, then after enabling HW flow control using .ioc file is there anything else that I will have to do to get the Hw flow control working?

I am using USART2 in DMA mode for Tx/Rx. I have attached the USART configuration after enabling HW flow control CTS/RTS. Are the configurations corrrect or do I have to modify anything?
