Hello,

I am use STM32Cube ver. 4.16  and STM32F3xx HAL Driver version number V1.3.0.When using HAL_UART_Receive_IT , during more than once unless you remove a communication cable 

: the program enters an IT IRQ infinite loop

During more than once unless you remove a communication cable

Hi yildirim.yi_it,

What kind of error you get then ? Is it overrun error ? Since you have generated the code using CubeMx 4.16 , may you share you .ioc file. -Hannibal-

Communication cable to plug and unplug several times , it IRQ endless loop.

Yes, errorcode = 8 Overrun. Attach File .ioc

Hi

yildirim.yi_it

,

It seems you have an overrun error due to pending interrupt.

In order to clear the pending interrupts we provide a specific macros in stm32f4xx_hal_uart.h file that can be used directly by the application (when needed).

Please refer to the Exported macro section in stm32f4xx_hal_uart.h file. The specific macro to clear the overrun pending interrupt is

__HAL_UART_CLEAR_OREFLAG()

Thus you can perform this to avoid overrun issue:

__HAL_UART_CLEAR_OREFLAG(…)
HAL_UART_Receive_IT(…)
