&par Example Description

This example provides how to establish multi-Processor communication in USART.
In this example, USART1 as the slave and enter mute mode, USART2 as the master will
send the address flame to wake up USART1, and then send data.
if USART1 received data equal to USART2 sent data, LED2 will on, else LED2 will twinkle.


&par Hardware Description

J2 and J3 Should be shorted.
using LED2(PB5).
using LED3(PB4).
USART1 RX(PD6) -> USART2 TX(PD3)
