I'm not sure there is that level/type of support here. The code is not compilable as provided, and I don't have this board.

Review if your project includes an stm32f1xx_it.c type file with an USART1_IRQHandler() function.You don't explain what the code does on your board now, does it work as expected, does the LED toggle? Does it echo back characters to the terminal.If you are not wedded to the HAL, I have posted working IRQ examples for the STM32F1 parts using the SPL.

hi,

The code working as follows:when the board gets connected, the led will be turned on and we can type anything on the keyboard,all that appears on the screen/terminal.But the led doesnt turn off .It continues to be on and nothing happens to led2.It remains off all the time.But it doesnt work as an interrupt.My project includes an stm32f1xx_it.c type file with an USART1_IRQHandler() function.but i havent written any code in it.
