代码说明：

  //实验板的AVR程序，uart应用，和计算机通讯，回送PC发送的数据 //接线定义：PD0-RXD PD1-TXD 开关位置：SW6-7/8打开。 //使用串口调试器，使用十六进制方式，首先让PC发送一个字符给MCU，然后将接收到MCU返回的值。 //记事：本程序旨在对uart的理解与演示，程序适合初学者使用. //使用片外8MHz晶体，9600bps波特率(//Experimental board AVR procedures, uart applications, and computer communications, PC loopback send data// connection definition: PD0-RXD PD1-TXD switch location: SW6-7/8 open.// Use the serial port debugger, use the hexadecimal mode, let PC send a character to the MCU, and then will receive the MCU to return value.// Note: This program seeks to UART understanding and demonstration of procedures suitable for beginners to use.// Use the chip 8MHz crystal, 9600bps baud rate)
