Usart 1 how rs232

[FSant.18]

I need to use the serial usart1 how comunication and receiver data by interrupt​

[S.Ma]

As setup details are missing, the answer will be generic: Get the cube sw package for the stm32 family you chose, browse the folder for the nucleo closest to your target mcu and look in uart example witg interrupt.
