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.
