Description: 使用DSP软件实现UART功能.一般教科书上提供的UART收发的程序往往是一段采用轮循（Polling）方式完成收发的简单代码。但对于高速的AVR来讲，采用这种方式大大降低了 MUC的效率。在使用AVR时，应根据芯片本身的特点（片内大容量数据存储器RAM，更适合采用高级语言编写系统程序），编写高效可靠的UART收发接口（低层）程序。下面是一个典型的USART的接口程序。-use DSP software UART functions. General textbooks UART transceivers provide the procedure is often used for Round Robin (Polling) transceiver accomplished a simple code. But for the AVR-speaking, the adoption of this approach greatly reduces the efficiency of MUC. The use of AVR, according to the characteristics of the chip itself (large-capacity on-chip data RAM memory, more suitable for the preparation of high-level language system procedures), the preparation of highly efficient and reliable UART interface transceiver (lower) process. Below is a typical USARTs interface procedures.

Description: Also the USART automatically senses the start of transmission of RX line and then inputs the whole byte and when it has the byte it informs you(CPU) to read that data from one of its registers.
The USART of AVR is very versatile and can be setup for various different mode as required by your application. In this tutorial I will show you how to configure the USART in a most common configuration and simply send and receive data. Later on I will give you my library of USART that can further ease you work. It will be little complicated (but more useful) as it will have a FIFO buffer and will use interrupt to buffer incoming data so that you are free to anything in your main() code and read the data only when you need. All data is stored into a nice FIFO(first in first out queue) in the RAM by the ISR.
