用8251A实现PC机通信与控制的研究

摘要

In order to broad pc-8251A chip based on a variety of communication and control, the article deeply studies the performance of 8251A chip with logic algebra and human interact way. Second,the article summaries the needle on the pc 8251A chip communication and control. At last, the article with an example design of a hardware interface circuit and software programs.%该文为拓广PC机基于8251A芯片的各种通信和控制方式,用逻辑代数和人类正确交互方式对8251A芯片的性能进行了深入研究,总结出了PC机针8251A芯片的多种可行的具体通信和控制方式,并结合一个通信实例设计了相关硬件的接口电路和软件的代码.
