How to manage two UART (USART2 and USART1) under Interrupt

If you like it, share it

There are different possibility to use the UART under Interrupt, for instance use PRINTF but this mode use a loot of code or, more efficiency is to use the Call Back.

In this example we use the Call Back modality.

This project was tested on NUCLEO-F030R8, was developed using the Cube-MX and the project is for ATOLLIC.
Thanks to Cube-MX is easy move this project on other STM32 mcu but also generate the same project for other IDE (KEIL, IAR, etc)

For use this project connect the NUCLEO-F030R8 to PC and use a terminal emulator, we suggest TeraTerm.
This because the USART2 is transferred to the PC like a USB virtual com port.
