| 摘 要： | 对基于S3C4480微处理器和uClinux操作系统的嵌入式系统，利用异步串行通讯芯片TL16C554A实现了多串行通讯接口的扩展。针对半双工RS-485通信方式，在串口驱动程序中采用直接判断TL16C554A的缓冲区状态的方法，实现了数据收发的自动控制。本文的设计和方法已经成功应用在远程监控系统中，系统性能稳定可靠。

| Abstract: | Based on the microprocessor S3C44B0 and uClinux,extended multiple serial ports are realized by an asynchronous communications element of TL16C554A.Under the half-duplex RS-485 communication mode,a novel control method of receiving and sending data is implemented by straightly distinguishing the state of TL16C554A's buffer in the serial ports driver.The results have been successfully applied into a remote monitor system,the system runs steadily and reliability. |
