摘要
串行数据通信是各种单片机多机应用系统和开发系统中不可或缺的功能 ,而如何实现通信双方速率的匹配极为重要。文中提出了一种由从机自动适应主机波特率的新方法 ,此法方便实用 ,握手时间快。此方法成功地应用于SST89C5 4 / 5 8构成的 IAP编程系统中 ,同样也适用于各种类型的单片机系统。
In the system of distributed and emluator for singlechip, it is absolutely necessarily to use the serial port to transmit data.And it is important how to realize bilateral matching of baud rate. This paper presents a new method for hypocomputer to automatic follow the maincomputer′s baud rate. The method is simpler and it is quicker to set up ACK. The method was applied to the IAP for SST89C54/58 successfully. In the same way, It is applicable for other type systems of singlechip.
